Knee strengthening exercise that is simple to do at home. This simple quadriceps knee extension exercise is easy to do at home and helps get your leg stronger. This is an open kinetic chain exercise, which is good for strength, but you also need to do some closed chain excesses for functional strength once able.
We’re going to work on a straightening exercise. This is an open chain exercise, but we’re still trying to get a bit of strength in that quadricep muscle, in the thigh here, post-surgery. We’ve just had the brace off here for a little over a week. What we want to do is working on straightening the leg, pulling the toes up, trying to get to full straightening without cheating through your hip. Because the quadricep muscle in your thigh is weak, when you lift the leg you want to lean back through your body. Other ways to do this are sitting in a chair when you have back support. Think about tilting your hip forward just a bit more — it’s a little harder to straighten, but you’re really making the quadricep work through a full range, and a little bit of a lag with the quadricep here so that it’s harder for him to get there. So again, working with repetitions to fatigue, maybe do three sets of 10-15 repetitions.
