This may not be exactly what you are looking for, but I work with a lot of sports professionals and enthusiasts with a lot of experience with knee problems (including IT band, ACL, MCL and arthritis). There is a lot you can do with excellent supplements (made in US, clinically tested, top rated company for business ethics and sanitary conditions) for both muscle repair/recovery and joint issues & inflammation. You could certainly go this route while investigating your medical options. If it takes care of the whole problem, excellent. If not, it will reduce the inflammation and pain, and speed your recovery from any surgery you decide to pursue. If you want to speak to someone with experience in this area (free), this is a great network of people who help.
