Anyone here have knee problems?
20+ years ago I had an arthroscopy done because a sports med doc thought I had partially torn the meniscus in my left knee. When I woke up he told me it was arthritis and my knee looked like it was 65 years old (due to too much basketball in my earlier years) and that I would need a knee replacement by the time I was 50. I held the replacement off until I was 59 and was tired of the constant pain when walking or standing. Stairs were not my friend either.
Anyway, the total knee replacement three years ago was the best thing I ever did - I was bowling again 3 months after replacing the knee in my sliding leg. It's a great thing to be able to walk without pain. Only thing is that I'll never have a NBA career since the I'm not supposed to either run or jump on the replaced knee.
Suggest you get a really good joint specialist to check out your knee.
