Partial Knee Replacement (unicompartmental knee replacement) is an operation that has been around for more than 60years! It actually was the precursor to today’s modern Total Knee Replacement operation. The operation has gone through many evolutions along the way and today is a very technical and highly successful operation when applied to the right patient. This operation enjoys superior results compared to Total Knee Replacement (TKR) in many characteristics including: natural feel, range of motion, stair climbing ability, speed of recovery after surgery and longevity of survivorship. Any individual patient with knee arthritis may or may not be a candidate for this procedure.

Metal on Metal

Fifteen years ago lab studies revealed that metal-on-metal hip replacements had lower overall wear compared to metal-on-plastic hips. Engineers measured the volume of wear particles produced over simulated 10, 20 and 30-year spans of hip wear in the laboratory. The smallest volume of wear was produced by ceramic balls rubbing against ceramic sockets. Only slightly more wear was produced by metal balls rubbing against metal sockets. The traditional coupling of metal balls against plastic sockets produced far more wear than the other two. As a result, engineers believed that ceramic-on-ceramic and metal-on-metal wear surfaces in hip replacement would exhibit superior long-term performance in patients. That’s not the way things turned out.
