Hello @katienaturegirl, Welcome to Connect. I think you have made an excellent choice prolonging the surgery as long as possible and choosing to lose some weight along with physical therapy and injections. I had my right knee replaced 2 years ago at age 76 and it had been bone on bone for 3 or 4 years and I finally couldn't avoid surgery if I wanted to remain mobile. I also had several cortizone injections prior to the replacement and had asked my surgeon about hyaluronic acid injections but he told me that he didn't think it would help at the stage of my knee. One thing that really helped my recovery and the surgery go well was doing the pre and post knee replacement exercises faithfully and building up the leg strength. Here's some information you may find helpful

Has your doctor recommended any specific exercises along with the physical therapy to help strengthen the knee?
