My first TKR was in March 2014, so my shots started years before that. They were "gel" shots, hyaluronic acid, but I was given only one shot at a time and told I could not have shots any closer than 6 months apart. I don't recall any kind of "series" of shots being offered or available at the time. Like @AndyL0711 said, it is major surgery but still considered elective. As a result, I had to go through just about every test imaginable to make sure that I would survive an elective surgery. I'm not sure if that is still the protocol.
Recovery was initially tough at times, but I have no regrets having had both knees replaced. Even though X-rays showed my left knee in worse condition from the arthritis, it was the pain in my right knee that drove me to it. I could not complete my follow through when swinging a golf club due to the pain. There was no way I was giving up playing golf! I was back to swinging a golf club on the range, starting with chipping and putting, I would say about 6 weeks after each surgery, but was not cleared to actually go out on the course until just about 10 weeks after. My surgeon's concern was me falling, maybe getting into or out of a trap, or slipping on wet grass. A fall onto the knee early on could prove to be problematic.
