Total Knee Arthroplasty: An Examination of Alternative Bearing Surfaces

Total knee arthroplasty (TKA) is a widely performed surgical procedure that provides pain relief and functional restoration to patients with end-stage knee osteoarthritis. While TKA has demonstrated high success rates, the longevity of the implant can be affected by factors such as wear of the bearing surfaces and the development of periprosthetic osteolysis (PPOL). The bearing surfaces are the components of the implant that articulate with each other, and their wear can lead to the generation of debris, which can trigger an inflammatory response and potentially lead to osteolysis (bone loss) … Read more
