Re. Oxford knee procedures...eleven years ago I had both knees done at the same time. Awful post op pain that was poorly managed by The Number One Oxford surgeon in a major Midwest city. I returned at five years for a long term follow up, stated ongoing discomfort, especially after golf. X-Rays were fine so the knees were fine thank you very much. Continued to struggle with periodic cortisone shots in a new city with a new doc. Current xrays show major wear on the plastic slide and some loosening from the bone. He wondered why the Oxford was used since I am quite bow legged and there is a lot of pressure on the joint. Even so, we walk 4-5 miles a day, then elevate and thank goodness for tramadol. But....come Friday a total knee is going in with the other one likely being done within the next year. I was told they should last close to 20 years. My advice to anyone considering them is to do your research better than I did. Probably not a good choice if your legs are not real straight. And....if arthritis is an underlying issue, it will likely not be eliminated by a partial and may well continue into the rest of the knee-over time of course-and might require a total revision at some time. And, if you decide on an Oxford, get a surgeon who does a bunch of them and ask them about their rate of success and how many require revision surgery. Best wishes to anyone who needs knee replacement...
