Hi all, I had MPFL surgery on my right knee almost 8 weeks ago. They attached a synthetic bit of rope instead of using my hamstring. They gave me stretches and some rehab to do while at home which was done. Im really struggling to get more than a 60 degree angle bend with my leg as when i try, it feels really stiff, pulls and generally alot of pain when i get to around 45-50 degrees. My Dr has told me i have 4 weeks to bend it at least 90 degrees or they will put me to sleep and do it themselves.....! Any advice would be great as im really worried.
