BIOMECHANICAL CONSIDERATIONS FOR TOTAL KNEE ARTHROPLASTY

摘要

Total knee replacement (TKR) is now recognized as a viable surgical option for managing dogs with severe to end-stage stifle joint osteoarthritis. The goal of this presentation is to briefly review the biomechanics of the normal stifle joint and to describe how this information has been used to guide the design and manufacture of contemporary TKR implants. The influence of implant design, surgical technique and post-operative care on TKR function and survival will also be discussed, with particular reference to the critical issue of mechanical wear of the articular surfaces and disruption of the cement-bone or implant-bone interface.
