I had a successful TKR last June. Very pleased with results and have resumed active lifestyle. Fishing, biking, playing with grandkids etc. Over the weekend I did something very dumb. While playing with twin grandchildren ( 8 years old ) in their pool, I jumped in to dunk a basketball. Unfortunately, I forgot that the goal was in the shallow end. (haven't been in the pool for over a year ) I landed straight legged on my TKR leg and it HURT ! I can walk without sharp pain but knee just aches like bone pain before TKR. Pain increases during day and sleep is VERY tough. I begged and have appointment this afternoon with surgeon who did my surgery. Hope I haven't ruined great result. Any similar experiences or thoughts? Thanks.
