I’m six months post-bilateral TKR with ROM 126/0 in both knees after 50 intense sessions of physical therapy. Prosthetic placement is perfect. However, I’m 3-5 degrees hyperextended in my left knee at the standing phase of my gait. I have pain, stiffness and instability in my left knee. I also have left foot supination, left hip pain while walking and have calcium fragments in my left quad near the kneecap. I used the best knee surgeon in town who said he’s never had a patient complain of post-op hyperextension and that I’m “hyper-sensitive” and “hyper-aware.” Are there any exercises that can fix this. My surgeon has suggested that a slight heel lift in my shoe may help but is already considering surgical repair next year.
