I had a total knee replacement about a year ago.It was me left knee.It was in March of 2011 that I had the procedure.Seven months later November 2011 I had my right knee done.Around March 2012 I had a mishap.My Knee started to bend while I was bending over to fix something.It Bent back too far and I could not stop.I ended up on the floor As time went on things got worse.I had an X-ray and it showed a fracture of the right knee. That was repaired in July 2012.Four weeks later after the cast was off Another X-Ray showed that the repair has started to unravel.My question is two fold. Has anyone ever had a problem with Knee Replacement.Secondly How Long should one wait between Knee replacements.?View Thread
