This chapter will entail a review of the available processes that can be utilized to properly analyze how and why a polymer insert in a total knee arthroplasty implant failed. total knee arthroplasty polyethylene wear analysis...

... Inflammatory cytokines have been proposed as potential biomarkers for damage in total knee arthroplasty (TKA). This study sought to compare the levels of inflammatory cytokines (TNF-α, IL-1β, IL-6, IL-8, MCP-1, MIP-1α, MIP-3α, GM-CSF, and M-CSF) in synovial fluid of retrieved cadaveric primary...

... for pending implant failure, serve as a potent surrogate endpoint for clinical trials, and provide important insights into the role of implant performance on clinical success in joint arthroplasty. total hip arthroplasty total knee arthroplasty adverse local tissue reaction histopathology retrieval...

... Total knee arthroplasties are subjected to high slip velocities and constantly changing velocity vector directions, as they mimic the anatomical conditions of the natural joint. Together with fluid film thickness and applied load, the velocity difference between the two bodies defines the amount...

... In this study, patients who played sports after undergoing a total knee arthroplasty (TKA) were functionally analyzed and their degree of satisfaction was surveyed. The study group consisted of seven men and four women (out of a group of 89 total knee arthroplasties). They were evaluated...

... wear against a failed metal backed patellar component. In the absence of these extreme wear conditions, we have not observed significant problems associated with Ti-6Al-4V as a bearing surface in total knee replacements at follow-ups of 7 years. titanium wear total knee arthroplasty Miller...

.... Femoral and patellar implants were retrieved from 40 patients undergoing revision total knee arthroplasty (TKA). Only all-polyethylene dome-shaped components were selected. Patellar implants were studied and graded for evidence of wear. Conformity data were then compared with wear data to assess...
