“Longitudinal Assessment of Cartilage Injury and Remodeling After Anterior Cruciate Ligament Rupture and Reconstruction:”
The proposed study will establish novel relationships between intra-articular mesenchymal stem cell (MSC) recruitment, synovial inflammation, biomarkers of cartilage degeneration and joint inflammation, clinical patient factors, and downstream alterations in cartilage composition and morphology to provide novel insights into the pathoetiology of post-traumatic osteoarthritis (PTOA) after ACL injury and reconstruction. The study aims to enroll N=38 total patients with primary, isolated rupture to their anterior cruciate ligament (ACL), who have agreed to participate in the study and who will undergo primary surgical reconstruction by an orthopaedic physician at our two sites. Patients will undergo baseline magnetic resonance imaging (MRI), baseline clinical evaluation, and undergo a baseline blood draw. Subsequent imaging and clinical evaluations will be longitudinally performed at several postoperative timepoints up to 12 months postoperatively.
