My question is regarding a partial ACL Tear involving the posterior lateral bundle in my left knee. I have been experiencing for several months a pinching sensation in my knee. Anytime I flex and bend the knee when walking without a brace I can feel the pinching. It's slightly less with the brace on and provides temporary relief. It’s gotten to the point that I don't want to have to wear a brace every time I go out. The pinching sensation is no fun, and I am ready for my left knee to feel normal again. Do you think I should get another MRI? After my second knee surgery on the left knee for a Medial meniscectomy, anterior synovectomy, and fat pad resection, my PT at the time noticed I was hyperextending my left knee and it took them until mid-August to finally get me into a top shelf ACL knee brace.
