I injured my knee about 12 weeks ago. I had an MRI and my main issues are a grade II sprain of the MCL and a sublaxation of my patellar tendon. I had 8 weeks of physical therapy and they said that wearing a knee brace would not allow my muscles to strengthen and that they needed to be stronger to make my knee track correctly. Today I went to the doctor and he said that I needed to wear a brace to see if that would help the tracking. So are my muscles going to become weaker from wearing the brace? Should I try to do physical activity without it?
