Our user asked: "Hello, I had a concern. First off, let me say that the knee problem I am trying to correct is Patellar Subluxation, I am doing a strengthening program from a phycsical therapist and am currently working on flexibiity as well. Now, one exercise that I have been doing is a sing leg press on the Paramount Leg Press machine. I notice that as I reach the end of my set, my leg gets a little exhausted and starts to wobble, mostly inward. I have experienced no pain thankfully, but am concerned about this. Should I keep my knee as still as possible? and do you think that I can pontentially worsen my subluxating knee cap in result of my knees wobbling. I appreciate your time and effort, and I look forward to hearing from you! thanks!"

Ask a PT Response: "The "wobbling" or shaking of the knee is not unusual for this type of injury when performing the leg press. You are right to have some concern about sustaining further injury with performing the leg press as poor technique and mechanics could lead to injury. For my patients who experience this, I would either decrease the weight that they are pressing or decrease the number of reps and sets performed while closely supervising and getting constant feedback from the patient. Weight, reps or sets are gradually increased as to minimize the "wobbling" while achieving the objective of strengthening. Best of luck in your recovery."
