HOW TO DECREASE WEAR IN TKR
David Dalury
John Hopkins Hospital
Baltimore (USA)
Polyethylene wear is an inevitable aspect of TKR. Early TKR
designs had little osteolysis and wear. Mid 1980s designs
which introduced modularity had higher rates of wear. Newer
designs addressed shortcomings such as poorer locking
mechanisms, flat on flat designs and improved polyethylene.
The most intriguing “newer” design is the rotating platform.
Rotating platforms decrease wear by increasing contact area
and decreasing contact stresses.
Wear in TKR can be decreased by appropriate surgical
technique, implant design and patient selection. This paper
will discuss these topics in detail.
