I would appreciate your opinion. I know he will have some ideas. In my own experience, you are going to have to deal with the causes of this or you are heading for knee replacement in 10-20 years. I would be testing for my intracellular magnisium level and seeing a Rolfer in consultation. I also would be avoiding those movements that caused knee symptoms.
ANY symptoms mean damage is being done.
Let me know how you are doing in about a month. This is a resolvable problem AND it needs to be resolved. The first scope was after a severe fall while running a relay race with a 230lb man on my shoulders. My knee gave way and was forced into the ground. The first surgery resulted in the removal of both plicae.
