Well, I almost made it 30 years. When I was 17 years old and heading into my 2nd knee operation, my surgeon told me that I would eventually have to have my knee replaced. A third operation followed a few years later that removed a huge chunk of my medial meniscus in my left knee, and I knew that the surgeon's prediction would definitely come true, it was only a matter of time. Well, that time has come. Knee has been getting progressively worse with the years, even though I gave up all my strenuous activities years ago. A few weeks ago I was sitting on my sofa reading, and when I got up I could barely move my leg without serious pain. This was not the first time this has happened to me - for years it was only once or twice a year. More recently it has been every month or two. Finally decided it was time to get the knee checked out again, get the MRI, and see what was going on. I've had the cortisone shots, the synvisc, and while they offered very temporary relief, I knew it was time to consider surgery. MRI confirmed what I had been feeling - medial compartment was kaput. Doc said that the meniscus that was left was frayed and "holding on by a thread." He asked about the conservative options and how they worked on me. I told him that while they offered some relief, it was very short lived. After a good long conversation, he recommended a partial replacement. He said he didn't like operating on someone my age, but in my case there wasn't any other good option. This was the conclusion I had reached as well. I have my surgery scheduled for September 26th. I'm not overly worried about the operation - I've had three in the past and I know what to expect. Main concern I have is with pain management. I have a very strange metabolism, and most pain medications do not affect me at all, even opioids. Don't drink frequently, and I have never used drugs, but I have an incredible tolerance to both. I've been prescribed all manner of pain meds, and I could be taking Pez for all I could tell - no relief from pain, no drowsiness, no disorientation. So I'm wondering how I'll do with the surgery. I do plan to talk to the surgeon and anesthesiologist to discuss options.
