I am 27 y/o with damaged cartilage in my left knee (MRI) and my knee cap pinches closer on the inside (X-RAY) primarily where the pain is. I recently had 3 shots of Orthovisc. The 1st 2 shots provided instant relief with stairs and weight bearing. The 3rd shot really hurt going in followed by a couple hours of heightened pain and now the pain is back to where it was before the shots. What happened with the 3rd shot? Was it injected in a different location behind the knee?
