Cartilage Contact and Early Degeneration following ACL Reconstruction

Funding Source: National Institutes of Health 1R21AR062733-01 (PIs: Thelen/Kijowski)
Individuals who undergo knee ligament reconstructive surgery are at high risk for developing osteoarthritis (OA) at a relatively young age. This study will develop new imaging technologies to access whether small changes in joint mechanics that persist after surgery contribute to the early onset of OA. The technology and results will provide a scientific basis for evaluating new treatment options that better restore normal knee function and mitigate the potential for OA to occur.
