I had both knees replaced without a problem. It is nearly a year since I had the left knee replaced and I have achieved 130 degree bend with zero degree straightness, the right knee is at 125 degree bend with almost zero degree bend this knee was done 6 months ago. I would recommend OSC (which I already have) to anyone. The physical therapy has created a high level of efficiency and really has helped my rehabilitation. I would like to thank Dr. Scott and Mike Swanson for all they have done for me.
