I have noticed that my patients are getting better and better results from their knee replacements. I have been doing total knees in private practice for 26 years, so I have a good experience to look back on. i will give some credit to the rotating platform total knee, which I think has many advantages over fixed bearing knees. Besides being able to rotate more from side to side, I believe it has a “self-centering” function that helps balance the knee, particularly when the implants rotate going from full extension to full flexion. I see much less evidence of instability and excellent range of motion. The recovery also seems to be faster to me. The good news is, Total Knee Replacement is getting better – you should have yours done by a qualified joint replacement expert- one that does over 100 total knees a year, and has done a joint replacement fellowship.
