Hi all! I am a 63 year old active and fit male. 18 years ago I had an OATS procedure (bone graph) to repair a piece of detached bone on my right medial condyle. I re-gained about 80% usage over the next 2 years but it has since slowly declined now to about 50%. I can still do most things except run/jog but I have always had level 2-7 pain that I control with meloxicam only as needed. I have bad bouts that can last 1-2 months where pain and some limping are regular but I still function, and other months where it's almost normal. X-ray/MRI show the OATS repair is failing and close to bone on bone but not there yet. I found a great doctor, Dr Haynes and he thinks I would be a perfect candidate for a partial whenever I'm ready. I do pass most of the questionnaires but I know a PKR will need to be done eventually and wonder if I should do it now while I'm healthy, have good coverage, and time off, or wait until it wears all the way out in ?? years. I'd love to hear from some of you who were on the fence as I am, and how it worked out for you. Thanks!
