Medial femoral condyle cartilage restoration using a single-stage combined autologous-allogenic technique: a case report

IntroductionCartilage injjuries in the knee pose a significant treatment dilemma. Multiple cartilage restoration procedures currently exist, but often come with significant cost and multistage procedures.Case presentationWe report a case of a young, active female who, due to insurance limitations, was unable to undergo matrix-associated autologous chondrocyte implantation. The patient was instead treated with a single-stage combined autogenous-allogenic cartilage restoration. In the follow-up period, the patient endorsed marked improvements in Knee injury and Osteoarthritis Outcome Score, International Knee Documentation Committee Subjective Knee Form, and Western Ontario and McMaster Universities Osteoarthritis Index scores as compared to preoperative scores.ConclusionSingle-stage cartilage restoration with a combined autogenous-allogenic graft technique offers an acceptable alternative to currently available cartilage techniques, with excellent short-term patient-reported outcomes.
