I had shots in my right knee in April . They put a shot in my right knee every week for 5 weeks.The last shot they gave me hit the bone or something and I have had pain ever since. They want to do a knee replacement.However in 2001 I had an accident and had 5 fractures above my knee on my left leg. The Dr.had to put a rod in my leg and about 3 years later he removed the rod and said the screws were regressing. It left my leg over an inch shorter than my right leg so I have to have lifts on my left shoe and I walk with a limp. in 2007 I had to have back surgery . They fused the L 4-5. What I was wondering if the injury to my left leg would interfere with recovery if I have the knee replacement.
