Total Knee replacements (tkr) may sound like the silver bullet. But timing is key. The medical industry is a bit leary of saying the tkr will last much longer than 15-20 yrs (activity level/wear/tear on device is obviously important). However, statistics on success rates of 2nd tkr is much less successful, with much higher complications.

If the math works out and you're likely to need a 2nd tkr, depending on your knee issues, researching cartilage restoration could help prolong and possibly eliminate tkr. Research "denovo nt" solutions. Downside is many insurance plans don't cover procedure. However, sometimes health trumps $.

Best of luck,
