Knee Replacement Exercise Modification

Knee Replacement Exercise Modification

Today, I wanted to reply to a question that I got on the blog.

Here’s what Deborah asked of me:

Rick, what is happening in the video demo with the other leg? It appears to me that you have to over-flex the other knee while rolling forward and back. I won’t be able to do this with my clients who have knee pathology because it requires way too much flexion of the other knee. Generally, both knees are problematic. Can you explain why you show it this way?

Thank you very much Deborah for the question.

The exercise that we are talking about is, I have my client sitting, and let’s say that this is the knee that has been replaced in the knee replacement. What I was getting them to do is to lean forward and increase that flexion of the knee so I can bring it back and then get them to lean forward and increase that flexion of the knee.

Now, Deborah’s comment was, this is how I usually end up having the knee. The reason why I end up doing the exercise this way is because a lot of times when it relates to knee replacements one knee is replaced at a time as opposed to both. So they replaced one and see how it goes and they end up replacing the second.

Usually, the other knee is the good knee and ends up having better flexion in that knee. If this opposite knee is problematic, there are two options that I would recommend.

What I can do if both of the knees are problematic, is I can go from a straight position and I can bring in a ball.


I can also move that ball closer to me to make it more challenging, so bringing it back working on that flexion, and then straightening out. Pulling that heel back and working on that flexion. And this opposite knee, the other knee, is more in a straight position.


I have them both straight with good alignment of the leg, pulling that heel back to the comfortable point that is the pain-free point. Straightening and coming back up and I can keep the other leg straight as much as I can.


To make it more challenging, I can bring the ball closer to me and pull it towards me and end up getting more flexion in that knee.


Now if that ends up being too much of an issue or they just can’t do it, the next option that I can do is I can move to a bed. I recommend that they get on the bed, it’s a lot easier to get on and off the bed compared to on and off the floor.

Once again I am going to use that ball, my legs are straight and I can put my hands where I want, and I am getting them to pull that heel towards the seat and straighten out. Again, pull that heel towards the seat and straighten out.


Now, this left knee I can keep wherever I want, whatever is a comfortable position. It could be slightly bent or perfectly straight. I can put a pillow underneath it for support. I am making the exercise more challenging by moving the ball closer to my seat. I am bringing the heel towards the seat and straightening out and working towards that flexion.


So there you go, thank you very much Deborah for the question. I hope that helps out and explains why I chose that exercise and why I do that exercise, and gives you two options that you can recommend or give to your clients or you can do it for yourself when it comes to a knee replacement exercise.
