Rebecca Irwin and Dr. John Kennedy of HSS were awarded a research grant for a project entitled “The Effect of Platelet Rich Plasma and Tribosupplementation in Osteochondral Lesions Treated with Microfracture: An in vivo Rabbit Model” from the Arthroscopy Association of North America (AANA). This work will test the hypothesis that decreased friction improves integration of repaired cartilage with native host tissue by decreasing shear stresses during repaired cartilage development. If tribosupplemntation aids in cartilage repair, this information could alter the clinical approach to osteochondral lesion repair and directly impact treatment options for patients.
