Could pain in knee be caused by strain of the vastus medialis or  sprain of medial collateral ligament?
Patient: I have a history of trauma to the knee.  A physician diagnosed me as having sprained my medial colateral ligament and a 1st degree medial meniscus tear.  The physical therapist disagreed and said it was a only a strain of the vastus medialis.  So i was treated for that.  I was fine until returning to biking left my knee sore.  Now I'm experiencing slight pain.  My knee becomes extremely stiff after having a shower. What is going on? Doctor: Hi. My opinion is that a vastus medialis strain would have healed with physical therapy, but a meniscal injury can cause persistent pain or discomfort. An MRI will give a definite diagnosis. Meniscal tears do not heal easily and you may need an arthroscopy to clean it. I advise a visit to an Orthopaedic surgeon. Hope this answers your question.
