First Metatarsal Head Osteochondral Defect Treatment With Particulated Juvenile Cartilage Allograft Transplantation: A Case Series:

Background:Focal damage to articular cartilage, also called an osteochondral defect (OCD), can be a cause of pain and decreased range of motion. Recent advancements have led to transplantation techniques using particulated juvenile articular cartilage allograft. This technique has been applied to the first metatarsal head to a very limited degree, with no published results to our knowledge. The aim of this study was to review the clinical results of patients who underwent particulated juvenile cartilage allograft implantation for first metatarsal head OCDs.Methods:We performed a retrospective consecutive case series study. Nine patients, at an average age of 41 years, were treated for symptomatic focal osteochondral defects of the first metatarsal head with particulate cartilage grafting from 2010 to 2016. Patients were contacted by phone to assess interest in returning to the office for follow-up, where weightbearing radiographs of the foot were obtained and a foot examination was performed.Results:At an...
