Clinical Trial Summary

With IRB approval and informed consent, patients (n=10) (18-50 years old) with post-traumatic knee OA and requiring a tibial plateau and meniscus arthroplasty plus a femoral condyle arthroplasty will be enrolled in the study. Primary criteria for inclusion will be Grade IV changes in the articular cartilage of the femoral condyle and tibial plateau and meniscal pathology in the medial or lateral femorotibial joint as determined by physical examination, diagnostic imaging and knee arthroscopy by the PI. Exclusion criteria include Grade III or IV changes in any other compartment of the knee, acute injury to any other part of the affected lower extremity, or inability to comply with the protocol. After enrollment, patients will undergo standardized knee radiography, and complete assessments (described below). Size-matched (standard clinical methodology) proximal tibia with meniscus and distal femur allografts from the same donor will be obtained from a tissue bank (Musculoskeletal Transplant Foundation, Edison, NJ) who has licensed the MOPS technology. The medial or lateral femoral condyle will be replaced using our novel instrumentation and technique described above. Tibial plateau-meniscus grafts will be trimmed and used to replace the entire medial or lateral tibial condyle while sparing the attachments of ACL, PCL and respective collateral ligament. The tibial plateau graft will be fixated using commercial available implants used for bone fixation. In the event that the meniscus has been detached from the tibial plateau during graft harvest, the periphery of the meniscus will be sutured to the capsule following standard meniscus transplant procedure. Patients will undergo controlled post-operative rehabilitation according to standard protocols for osteochondral with concurrent meniscus allografts. Range of motion, VAS pain score, SF-12, Tegner score, International Knee Documentation Committee (IKDC) subjective and objective scores, PROMIS Bank v1.2 - Physical Function-Mobility, PROMIS v1.1 - Global Health, PROMIS Bank v1.1- Pain Interference, PROMIS Bank v1.2 - Physical Function and Marx score as well as complete radiographs of the affected knee will be obtained prior to surgery and at 6 weeks, 3 months, 6 months, and 12 months after surgery to evaluate healing, function and evidence for arthrosis.
