Preparing for Knee Replacement Surgery

by Shari
Deciding to undergo a total knee replacement (TKR) surgery is not an easy decision to reach. There are many factors that lead us to undergo this elective surgery. Most often it is because our quality of life is poor and we become frustrated with what we are unable to do. Also, having chronic pain can be very wearing and there comes a point when we really can’t tolerate it anymore. 

It is at that point that we agree to have this surgery (see Knee Replacements and Yoga). Because many of us are pro-active in our health care and expect to be equal partners with our health care providers, we’ve been asked to write about how best to prepare for this surgery.

In general, when you consider practicing yoga for a specific condition or goal (which is when it crosses over into yoga therapy), for best results you should be global in your approach. Just muscle strengthening for a particular joint (knee) is not enough, as I will discuss below. So I’m going to break down pre-operative preparation into three basic categories.

Preparing for Emotional Health

The first area to consider is your emotional health and wellbeing. Setting your intentions is very important. Being able to do visualization, meditation, and basic breathing (pranayama) for stress management is critical pre-operatively. Practicing these skills so they become habitual will set the scene for a successful surgery and post-operative recovery. See The Relaxation Response and Yoga for information about using yoga to manage your stress.

You can also prepare spiritually for your upcoming surgery. Start by honestly confronting your own fears and emotional responses to having the surgery. Imagine what life will be like post operatively. The essence of yoga is cultivating equanimity in the face of difficulty. You might not always like what you have to accept but to surrender to it fully is how you can come to grips with difficult decisions.

So commit to your decision to undergo Knee Replacement Surgery as you would to any other form of work or practice (see Tapas: Working with Dedication). Choosing this surgery and doing the work to accept and fully believe in the success of the surgery sets your neural immunological system for success in a good surgical outcome. Your brain, emotions and belief systems are all part of your inherent healing mechanisms.

To address your psycho-emotional health pre-operatively, you can also examine your current sleep habits. Healthy sleep is imperative both pre-operatively to prepare us for the surgery as well as in the post-operative period.

Whether you employ principles of deep physical relaxation, practice good sleep hygiene habits, or both depends on you. See 5 Tips for Better Sleep for information.

Preparing Your Energetic Body

To prepare your energetic body for surgery, look at your breathing patterns and postural habits. When observing your breathing patterns, notice how you breathe and what you do with your breath when you are fearful or anxious versus when you are safe and relaxed. Observe what happens to your breathing pattern and overall postural holding when you imagine the surgery and the necessary care and work that will follow the surgery. Knowing your typical breathing patterns will allow you to cultivate breathing patterns to promote your sense of safety and relaxation.

To cultivate breathing patterns that promote safety and relaxation, I recommend taking a simple, comfortable position like Savasana and practicing simple Ujaii breathing with no retention or manipulation of the breath pattern.

Learning to identify your physical holding patterns can also aid your physical comfort both pre- and post-operatively. Pain is a stressor and affects you physically, so it is important to practice breathing to relax both your physical body as well as your mind.

Preparing Your Physical Body

Preparing physically for the operation is not just about strengthening your knee muscles; you should give attention to several physical areas, including your core, your hips, your legs, your ankles, and your upper body. And, obviously the way you can do asana will vary from person to person, as some of you can still get down to the floor while others cannot. But if you want to practice supine or seated poses and can’t get down to the floor, trying practicing on a tabletop. (Scoot your butt onto the table and then swing your legs up and onto the tabletop.) 

The key to your preoperative management from a yogic therapy perspective is to consider your entire body. You may be having the surgery on “just your knee” but the effects of the procedure are global in how you will recover and heal.  

Core. For basic core strength, practice Boat pose (Navasana) and variations. 
You can do leg lifts in Construction Rest position (on your back with knees bent and soles of the feet on the floor) or Bridge pose. March by lifting foot leg off of the ground and holding it up for a count of 5, and then repeat on the other side. Continue to alternate until your hips are fatigued.

Hips. To strengthen your hip abductors, price side-lying leg lifts (sometimes known as “clamshell”). If you can lie on your belly, practice left lifts in Locust pose (Salabasana).

Also, lie on your back with pillows under your knees to support them in a bent-knee position, and then, one leg at a time, lift from your heel to straighten your knee.  

Knees. For your problem knee, you can work on cultivating range of motion. You will either be having difficulty bending your knee (flexion) or straightening it (extension). 

If you have problems bending your knee, try sitting on the edge of a chair with your leg stretched out in front of you. Then slowly step your foot backward the chair, gradually bending your knee, as far as you can. You can also try working with Dancer’s pose (Natarajasana), balancing on your good leg and slowly lifting your problem leg behind you in a bent knee position. 

If you have problems straightening your knee, you can work with your leg in Krounchasana (Heron pose), either on the floor or seated on a chair, slowly straightening your upright leg as much as possible. Or, you can sit on one chair with another chair directly in front of you. Bring your problem leg onto the second chair seat so it is fully supported (your foot can be hanging off the edge), and slowly straighten your leg as much as possible, coming into a slight forward bend if desired.  

Ankles. Simple ankle circles are excellent for circulation. 
For ankle flexibility, try sitting on the edge of a chair legs stretched out in front of you and, keeping the soles of your feet on the floor, walk your feet slowly back toward the chair until you feel a stretch on your calves and heel cords. 

To strengthen the calves, practice rising onto your toes in Mountain pose. Start in Mountain pose with your soles of the feet completely on the ground and on an inhalation, rise up onto the balls of your feet. Exhale, and return to Mountain pose and repeat the cycle several times. This will also help cultivate your ability to balance. If it’s not possible to do this standing, you can make the same movements while sitting on the edge of your chair, with your feet on the floor in front of you. 

Balance. Although balance is important to continue to cultivate, standing on your pre-operative leg in traditional yoga balance poses may not be possible due to pain and instability. So try this two-legged balance pose, which is a version of Mountain pose. Start in classic Mountain pose, with your feet parallel to each other. Then step your right heel in front of your left toes, so your two feet are in line with each other. To come out of the pose, step your right foot back to a parallel position with your left, and then repeat on the other side by stepping your left heel in front of your right toes.

You can also work with other aspects of balance and proprioception. Try Mountain pose with your eyes closed, for example. You might not realize how much you use your sight to balance, and removing sight from the equation helps foster other balancing abilities. Add in arm and/or head motions to challenge your balance even further. 

Upper Body Strength. Because your arms will typically have to bear more weight after your knee replacement (because you can’t fully bear weight on the leg with the new knee replacement), working on upper body strength in advance will help you be more mobile after the operation.

To build upper body strength, try the chair version of Upward Plank pose. This helps build the muscles you’ll need for walking with crutches or a walker post-operatively.
You can also work with either full Plank pose or the version on the forearms, which build both upper body and core strength.   
Standing Poses. Depending on your pain levels, full weight bearing may be limited for you and not causing pain or further joint deterioration is important. So learning to be flexible in how you do your standing poses is key. Rather than giving up these poses temporarily, you can continue to practice your standing poses with the aid of a chair. For example, you can do Warrior 2 pose with your pelvis on a chair seat, the bent front leg to one side of the chair and the straight leg stretched behind you on the other side. Other standing poses, including Warrior 1, Extended Side Angle, and Triangle pose, can be done in the same manner. 

Inverted and Restorative Poses. Supported inverted poses like Legs Up the Wall (Viparita Karani) are great for reducing swelling in the legs both pre- and post-operatively, as well stress management. However, you may not be able to get down to the floor to set up for and practice this pose. In this case, the easiest way to do Legs Up the Wall pose is on your bed, with your legs supported either by the headboard or the wall. Figuring out how to do this pose pre-operatively is a good idea because it will really help with edema management post-operatively.

For Savasana and reclined restorative poses, again, even if you have trouble getting up and down from the floor, you need not give up these important poses. One option is to practice these poses on a tabletop. Another option is to practice the poses on a firm bed that is not the one you usually sleep in.

Do You Really Need Knee Replacement Surgery? Maybe Yoga Can Help Instead

by Nina
Nude Woman on Her Knees by Michelangelo
“If you do not have bone-on-bone arthritis, in which all of the cushioning cartilage in the knee is gone, think about consulting a physical therapist about exercise programs that could strengthen the joint, reducing pain and disability, Riddle says.” —New York Times

I’m sure that by now we all know someone who has had a knee replacement due to arthritis of the knees (see Arthritis and the Knee and Yoga for background information). And while some this procedure is a clearly life changing for people who advanced knee arthritis, there is growing evidence that people may be electing to have the procedure prematurely gaining limited benefits from it. So many people considering the procedure might be better off finding other ways to improve their knees, such as strengthening the muscles around their knee joints and moving their knee joints regularly through their complete range of motion.

A recent article in the New York Times Think Twice Before Choosing Knee Replacement discussed two major studies published this year, in which researchers at Virginia Commonwealth University in Richmond conducted a surgical-validity assessment. In the studies Use of a validated algorithm to judge the appropriateness of total knee arthroplasty in the United States: a multicenter longitudinal cohort study. and Using surgical appropriateness criteria to examine outcomes of total knee arthroplasty in a United States sample., the researchers concluded that knee replacements should be judged appropriate for only those whose arthritis in the knee was “medically proven to be advanced.” (“Medically advanced” in this context means not just having severe pain but also being impaired in your physical functioning as well, such as, being unable to climb stairs, get out of a chair, or walk without aid.) The reason for this was that only those with advanced arthritis actually saw significant benefits from the surgery:

“The same researchers also found that people who were good candidates for surgery — basically, they had really bad knees — benefited substantially from the surgery, reporting much less knee pain and much better physical functioning in the months immediately following the procedure and again two years later. On one commonly used measure of knee function, their scores improved by about 20 points on average. By contrast, subjects whose surgeries the scientists deemed inappropriate did not improve much. After a year, their scores on knee function had risen by only about two points.” —New York Times

For people whose arthritis of the knees is not advanced, the New York Times recommended questioning the need for surgery and consulting your doctor to learn how advanced your arthritis really is. And if you make a decision to postpone the surgery and try exercise instead, yoga has a lot to offer you. Start by reading Baxter’s article on knee arthritis Arthritis of the Knee and Yoga for background information on the condition and to see which poses and practices he recommends in general.

Although this NY Times mentioned only strength building as a way of helping to manage arthritis of the knee, Shari says in her post Yoga for Osteoarthritis that moving joints through their range of motion is also essential for keeping them healthy. And this is where yoga can be especially beneficial, because the wide variety of poses allows you to move your knees through their full range of motion.

“People stop moving with arthritis because it hurts, but when you stop the joint motion you decrease the nutrition to the joint structures. The body tries to repair the area by laying down more bone to protect the area and the result is spurring, which then cause more irritation from the “bones rubbing.”

When the cartilage has deteriorated and there is no movement, the synovial fluid that bathes the inside of all synovial joints decreases, which then decreases nutrition to the joint and the cycle reinforces itself with pain=no movement=more pain with swelling and inflammation=even less movement. 

Yoga is so perfect for arthritis because it can stop that cycle by providing infinite variations in joint mobility and ways to maintain the joint alignment to improve joint weight bearing. You need to keep the joint moving in its full range of motion to keep the joint healthy, and yoga allows you to do that.” —Shari Ser

You should also consider your particular anatomical structure when thinking about managing your arthritis of the knee joints. Do you have bowlegs or knock-knees? Or do you typically hyperextend your knee joints? (If you don’t know, ask your yoga teacher or health professional to help you assess your knees for these conditions.) Because these three conditions are quite common, we’ve written specific posts on them. See:

Friday Q&A: Pain After a Knee Replacement, Part 2

This week’s question is a follow-up question that came in after the post we did on yoga and knee replacements (see Knee Replacements and Yoga) and Shari's answer to another reader about pain after a total knee replacement (see Friday Q&A: Pain After a Total Knee Replacement). It seems that pain isn't uncommon after a knee replacement, but in this case, the pain is coming several years after the replacement:

Q: My partial knee replacement was April 2007. I started back to Yoga this past summer-one day a week, but I found child pose with the knees wide uncomfortable, but I did do it for a few weeks this fall. I now have some pain in my knee and I'm hoping that I haven’t loosed the cement in the joint. Any help would be appreciated.

A: Thanks for writing in about this new pain in your knee. As always, I am not able to diagnose or prescribe a yoga program for you without first doing a more detailed history and physical exam in person, but I can share some thoughts that come to mind from the situation you find yourself in.

One of the challenging things to discern for new yoga students, or those returning after a long break from doing yoga is: How to gauge if “uncomfortable” is a potentially harmful warning sign from your body? This is tricky, because it may simply be that you are getting some intense sensation feedback from the body as you stretch and strengthen parts of your body that have been neglected for a long time. With the knees in particular, learning to recognize the difference between the healthy stretch sensation of the muscles and connective tissue lengthening versus the compression of the tissues and bones that often happens deep folds of the knee joints is an important skill to cultivate. The compression sensations can sometimes indicate pinching of tissues that could lead to inflammation, injury or bruising that may not resolve quickly or could lead to more chronic pain. It is sometimes hard to skip these poses—like Child’s pose—in a public class since they are so common unless you have an alternative offered by your teacher.  I often suggest that folks with knee pain flip onto their backs and draw the knees to the chest, essentially an upside down Child’s pose. Then almost all the pressure is off the knee joint and usually no pain is felt. The other thing to try is to vary the distance of the knee spread in regular Child’s pose until you find a distance that does feel uncomfortable.

It is also important to recognize that undergoing a knee replacement does not equal having the same healthy knee anatomy and movement you had before the surgery and the underlying knee problem that lead to your surgery. One of my students who had knee surgery to clean out a lot of arthritis damage to his cartilage found that his range of motion was less after the surgery than before, but he was now pain free. His challenge became how to gradually see if he could improve the range of motion without leading to recurrent pain.And another student of mine who had one knee replaced, but also had a second bad knee, found that although the new knee operated normally, the second knee become more painful secondary to the new way he was walking with essentially two very different knees. And sadly, having a successful repair does not guarantee that future dysfunction and pain will not arise.

In this case, it is also important to recognize the effect of the passage of time on both the surgerized knee and your other knee. A substantial amount of time has passed from 2007 until this summer of 2013. And with that the knees can undergo gradual changes in the architecture and function of the joint, such that the repaired knee can undergo undesirable changes, and unrelated changes could also have taken place. It could be that something has loosened in the replaced knee parts, but it could just a likely be some other structure, tendon, muscle or other structure, that could be the source of this new pain. This needs investigating! 

Until you have an exam and get a diagnosis from your orthopedic MD, avoid the positions that create immediate or delayed pain in the affected knee. Poses like Child’s pose include Hero pose, Thunderbolt pose (as well as poses that have just one leg in the deep flexion fold at the knee joint), front knee in Pigeon pose variations, the front knee in deep drop knee lunges, and any Lotus preps or full and half Lotus pose. Even some simple seated poses like Sukasana (Seated Crossed Legs) can be worth avoiding until you know what you have going on. Once you get a clear picture of what is happening, I’d suggest setting up a private session with an experienced yoga teacher or yoga therapist to design a home practice that can address your unique situation.

Friday Q&A: Pain After a Total Knee Replacement

Q: I have had a TKR (total knee replacement) in March this year (5 months ago). I still have pain and swelling in the repaired knee, mainly on the outer side and behind the knee. Is there any yoga exercise recommended to stabilize the knee and make it healthy?

A: I am sorry to read that your Total Knee Replacement (TKR) has not resolved all the issues you hoped it would have accomplished. Literature review states that 90% of all patients are pain free after six months, but sometimes the recovery period can take a full 12 months. Ten percent of TKR patients are not pain free within this time period.

Pain is a symptom of an underlying problem. The cause of the pain needs to be thoroughly addressed by the surgeon who performed your surgery. My advice would be to return to him and have him perform a complete exam, including diagnostic studies (X-ray, CT scan, blood work) to rule out any underlying infection and to ascertain the alignment of the knee prosthesis.

The other thing you might consider is a complete orthopedic examination by a physical therapist who is skilled with post-operative TKR rehabilitation, especially someone who can evaluate the biomechanical basis of your knee pain and look completely at your legs, hips, pelvis, back and how you move in space. A wonderful resource for you to check out is called Bridgebuilders to Awareness in Healthcare, a group of yogi rehabilitation professionals who blend traditional physical therapy and other rehabilitation disciplines with the practice and application of yoga in a therapeutic context to assist you in your journey back to wellness.

It is very common for the TKR to correct the arthritic cause of pain but if the patella is not tracking well and is not aligned within the patellar groove, then the imbalance when the quadriceps tendon contracts to straighten your knee will be extremely irritating. So if you are doing straight leg raises with or without weights, long arc quadriceps sets, or any other quadriceps strengthening exercises, the first thing you can do is stop anything that causes knee pain when the knee muscles are contracting. After you and your surgeon rule out any underlying pathology or prosthesis problems, you also may want to try to figure out how your current pain is different from your old pain. If you had knee issues similar to the ones you are having now then it is definitely important for you to see a rehabilitation professional.

If you are currently in a yoga class or have a home yoga practice, you really need to pay strict attention to the alignment of your hips, knees and feet as well as attention to how you move into and out of poses. You might want to stop all standing poses for now and instead work on passive inversions like Legs Up the Wall pose (Viparita Karani) or Chair Shoulderstand to see if you can mechanically drain some  of the edema. If the edema and swelling is under the knee cap, you could ask your surgeon if he will aspirate the fluid, and if he agrees, it might not be a bad idea to ask him to culture it to make sure there is no infection lurking in the joint.

I am sorry that I can’t give you a specific "yoga exercise" for stability because I can’t see your body and how it moves. But if you are feeling that your knee is unstable, this is a sure sign that the leg is weak and it is unable to balance on itself. Please be patient and be a good detective. If your surgeon's assessments all come back negative, that is a good conclusion because you will know you can work on the specific issues at hand. With diligence and compassion for your knee, it will hopefully progress and allow you to resume the activities that are important for you.

Knee Replacements and Yoga

by Shari

Nina asked me to add to Baxter’s previous post Arthritis of the Knee and Yoga about what the next step might be when your own self-care management techniques are not as effective and your quality of life is severely impacted. So I thought I would you give some background about the elective procedure total knee replacement and why you might elect to have it done. Professionally, I see a lot of total knee replacements in my work as a home health physical therapist, and I also have yoga students who come to my class either after the procedure or beforehand as they are preparing themselves for the surgery.

Although many people will never need surgery for arthritis of the knee, if you have severe joint damage, extreme pain that isn’t helped by other treatments, or very limited motion as a result of the condition, knee replacement surgery may be necessary. So if the arthritis pain in your knee worsens, and the exercise that once helped you feel better has become unbearable, your doctor may recommend a total knee replacement (TKR). Surgery for osteoarthritis can provide several benefits, including :
  • improved movement
  • pain relief
  • improved joint alignment
When you research the procedure, you will discover there are gender-specific knees, which are knee replacement models designed for women, and dozens of other options, too, including different materials, sizes and models from a variety of manufacturers. How do you choose? Generally, you don’t. Surgeons typically determine which implant they’ll use when they are in the operating room and actually looking at the structure and size of your bones.
X-Rays of Knee Replacements (from Wikimedia)
Prior to surgery, however, you should have an informed conversation with the doctor about your options so you can ask good questions about why a particular model might be chosen, and determine if you’re comfortable with the doctor’s approach and experience or whether you’d like a second opinion.

When only a portion of your knee has severe arthritic wear and tear symptoms, as confirmed by diagnostic testing as well as subjective complaints, you may be recommended to undergo a “partial or unicompartmental knee replacement.” This may be recommended because it helps to straighten up the joint, which has changed its position as a result of osteoarthritis. Partial knee replacement can be more effective and durable if appropriate and are less invasive. Recovery time is less because there is less surgical trauma.When the entire knee joint is replaced that is called a total knee replacement, and the ends of the femur, top of the tibia and often the patella (knee cap) are fully replaced.

When you are ready to return to your yoga class, you should take time to talk with your teacher about your knee replacement. I will routinely ask these students a series of questions:

1.    How long ago was the surgery?
2.    Are you still in pain?
3.    Are you still in physical therapy?
4.    Do you have any hip or back pain (either before or after the knee replacement)?
5.    How much mobility do you currently have? Can you get up and down from the floor?
6.    Do you have arthritis in any other joints?

So be prepared to provide your teacher with this information. Knee range of motion will vary widely both in a recent post-operative knee as well as a knee replacement that is over one year old. A lot depends on how much motion you lost prior to the surgery and how hard you worked postoperatively. The answer to the question “Can you get up and down from the floor?” is important because it tells the teacher a lot about a student’s flexibility and strength. Knee flexion will vary considerably, but I have never seen a knee replacement with 155 degrees flexion nor have I ever seen someone able to do a deep squat. Whether this just happens to be my student demographic or not, I don’t know.

When resuming yoga practice, alignment is a big deal with knee replacements because post operatively you want to avoid torque forces through the joint because that affects cement in the joint. “Closed chain activities,” where your weight is shifted with your foot remaining on the floor,” where your foot is lifted off of the floor with subsequent weight bearing will affect the joint differently. For standing poses, I teach students with recent knee replacements to pick their feet up and then replace and position as opposed to pivoting to change directions. Down the road, you can introduce pivoting if it doesn’t cause pain or discomfort. Liberal usage of props; walls, chairs, blocks will assist the student in not over-doing too quickly.

Strengthening all of the muscles that cross the knee joint as well as secondary stabilizers is also important. This means front, back and side leg muscles. Attention to hip alignment and strength also translates to protection of the knee replacement. Kneeling is problematic but not necessarily injurious to the new knee. Finally, pay attention to the feet—where is the weight on the foot? A lot of individuals who suffer from arthritic hips and knees have feet that need some tender loving attention. Baxter in his prior posts talked about feet (see Your Feet on My Mind), and I agree that where the body meets the ground and how we stack up from there is crucial in protecting our joints for longevity, especially when we become bionic.

I would like to add that lot depends on your pre-surgical state of health. If you have been active up till the day of the surgery then your recovery time will take about three months till you feel like you have integrated the new knee into your body. This is a rough estimate, but it seems about right for a traditional total knee replacement. Minimally invasive and partial knee replacements have less trauma, so healing and function comes more quickly. For those individuals who have lost a lot of mobility and have developed severe range of motion loss and significant loss of muscle strength, the recovery time will be more arduous because of all the structural as well as cardiac changes.

Finally I want to emphasize this: talk to your surgeon before and after surgery to know what your particular limitations and precautions may be, and remember to share them with your yoga teacher. Remember this is an invasive surgical procedure and everyone heals in a different manner. Be kind to yourself and remember that with a lot of hard work you will regain function and improve the quality of your life. This the reason why you decided to undergo this surgical option in the first place.
