Official title
Pathogenesis-Prevention of Post-Traumatic Osteoarthritis (OA): Effects of Distraction and Motion on OA
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Joint injury and trauma dramatically increase the risk of developing osteoarthritis (OA). The purpose of this study is to determine what factors lead to decreased pain, improved joint function, and repair of the joint surface in post-traumatic OA. Study hypotheses: 1) Ankle motion during distraction will result in clinically significant improvements in Ankle Osteoarthritis Scale scores, SF-36 scores, and improved cartilage thickness distribution over the habitually most heavily loaded portion of the articular surface, as compared to the use of distraction without ankle motion. 2a) Ankles with low geometric surface irregularity and greater range of motion will have better preservation of neo-chondroid tissue (increased normalized cartilage thickness and reduced longitudinal compressive strain in the habitually heavily regions of the articular surface) than those with high surface irregularity. 2b) Low geometric surface irregularity and greater range of motion will have reduced habitual focal or regional contact stress elevation. 3) Joints that have better improvements in Ankle Osteoarthritis Scale scores and improved cartilage thickness distribution over habitually heavily loaded portion of the articular surface will have improved normalization of synovial fluid markers of biosynthetic/degradative activity and oxidative stress.
