Failure Of Primary Total Knee Arthroplasty: Establishing A Baseline For Retrieval Analysis Using Well-Functioning Necropsy Specimens, Meredith Perkins

Theses and Dissertations (ETD)

Introduction. Total knee arthroplasty (TKA) is an effective treatment for end-stage osteoarthritis of the knee. While many patients have positive functional and pain outcomes following primary TKA, a subset of patients have suboptimal outcomes, such as unexplained pain or aseptic loosening of the implant components necessitating revision of the index procedure. The understanding of the exact etiology of these suboptimal outcomes of primary TKA is in its infancy. In order to elucidate the etiology of failure in primary TKAs, a baseline for the factors contributing to arthroplasty failure and dissatisfaction must first be established. The purpose of this study …

Total Knee Arthroplasty Wear Is Caused By Malrotation And Excessive Laxity, Erik Woodard

Theses and Dissertations (ETD)

Total knee arthroplasty is a proven technique which combines specially designed components and surgical processes to treat cartilage degeneration and alleviate pain in arthritic knees. However, this technique is limited by component design and surgical precision. Due to these limitations, knee arthroplasty components will eventually wear out, causing rejection and necessitating the need for a replacement. For this reason, it would be beneficial to experts if the primary causes of this wear could be identified in order to minimize the number of replacements.

This study aims to determine if a correlation exists between instability of a knee joint and the …
