In reply to stevelucocq:
Yeah, LOTS of recent experience. Daughter had two tears in knee cartilage last november. Short version of story is; because of youth (15 year old) all advice was to try to let it heal itself. After 5 months, not much progress, so arthroscopy booked. Still much pain, but that is partly because knee is weaker.
Advice from us - make sure the doc you see about it is a specialist and understands sports injuries, and the nature of the sport involved. Don't know how old you are; that does make a difference to treatment.
If you want full story, PM me, it would be a LONG post.
Most recent chapter - its mostly good, she finished 5th in YCS two weeks after op, and 6th in junior BBC 4 weeks after op, which wasn't bad.
