It all depends upon the level of recovery every patient is making. With our clinic Enhanced recovery protocols, patients usually get significant pain reductions in about 2-3 weeks with discomfort left at 6 weeks when they can drive. It is important to continue with physiotherapy as flexibility will positively affect the recovery and return to driving!

If your knee truly is 20 degrees short of extension and only bends to 60 degrees then its range of movement is from 20-60 degrees (ie 40 degrees)- which for a total knee replacement is extremely unusual. You mentioned the surgery was performed 3 years ago and that you have had several further attempts at increasing the range of movement including MUAs, CPM and an open (?arthrolysis) yet you have failed to improve. Some more answers to questions are required - was it a TKR following an arthrodesis (fusion of the knee), do you have an underlying neuromuscular disorder, have you consulted your original surgeon to discuss this further.etc...? Assuming your pain and dysfunction is similar to (or worse) than that before the surgery and no medical comorbidities preclude you from having further surgery then revision knee replacement would be a reasonable option.

Yes knee replacements can clunk and usually it is not significant. All knee replacements have hard bearings while the natural knee has soft bearings. There the natural separation of the bearing surfaces can cause clunks in knee replacements as they come back together. This clucking is worst when the knee has more fluid in it and the muscles are week. Therefore you get most clunking in the weeks following surgery and in a good knee it settles over a few months but never goes away entirely in some.

Yes. Assuming no medical contradictions, naproxen for a month or so would be a good idea. Naproxen is a non steroidal anti inflammatory drug(NSAID) and will reduce pain and swelling and help rehabilitation.
