Decisions, decisions!

So I had an appointment with my orthopedic surgeon today because my knees have been getting worse and worse. After taking new xrays, the surgeon asked me about total knee replacements. He showed me the xrays and went over how bad my knees really are. Your knees should be rounded and smooth. My knees are pointed, jagged and shaped odd. According to the doctor they are about 90 years old even though I am only 28. The surgeon wants to do an arthroscopic surgery on them first. That will clean them up and the recovery is about 2 weeks. The problem with that is that it only lasts for 5-10 years and then my knees will get just as bad as they are now. The alternative is the total knee replacements. The recovery is around 6 weeks but the outcome should be awesome. I am not sure what way we are going to go yet, but I think we are leaning more towards the knee replacements because I can't remember the last time that my knees were anywhere close to 100%.
