Picture taken looking down while sitting: Right knee (longer scar) was from Cartilage Transplant Surgery in 2000. The TKR scar that was done in 2008 is imbedded in the long scar and hardly visible. The left knee is from my recent TKR surgery seven weeks out, and seems to be healing nicely. What a difference!!! Various smaller scars are from scopes and lateral releases & surgeries done throughoutt the 1990's.
