Electronic Thesis and Dissertation Repository
Post-traumatic osteoarthritis commonly occurs as a result of a traumatic event to the articulation. Although the majority of this type of arthritis is preventable, the sequence and mechanism of the interaction between joint injury and the development of osteoarthritis (OA) is not well understood. It is hypothesized that alterations to the joint alignment can cause excessive and damaging wear to the cartilage surfaces resulting in OA. The lack of understanding of both the cause and progression of OA has contributed to the slow development of interventions which can modify the course of the disease. Currently, there have been no reported …

The metallic femoral components of total knee replacements are subject to in vivo surface damage and roughening that can severely limit the service lifetime of the bearing system. To date, there are no national standards by which to characterize the severity and damage modes of these critical bearing surfaces, and therefore it remains difficult to accurately assess how femoral damage influences total joint replacement bearing longevity. In vitro and in vivo studies have shown that severe surface damage of the femoral component can occur, however, there is still no defined test methodology that can identify or replicate the types of …
