Experience in repairing tibial defect with mortise and tenon bone grafting for severe knee osteoarthritis
Objective:To explore the surgical experience and technical optimization of mortise and tenon bone grafting in repairing tibial defect in severe knee osteoarthritis.Methods:A total of 50 pa-tients of the First Affiliated Hospital of Baotou Medical College of Inner Mongolia University of Science and Technology with tibial plateau defect for severe knee osteoarthritis were repaired by mortise and tenon bone graft.Results:All surgeries successfully completed without serious complications.All pa-tients were followed-up for 6 months to 11 years,with an average follow-up of 9.3 years.The post-operative KSS score was 84-92,with an average of 88 scores,which was significantly improved com-pared with that before surgery.Good knee range of motion were found in all patients at the last follow-up.In the last follow-up,the imaging results showed that defects of the tibial plateau bone were effectively repaired,the knee prosthesis was in good position and of reliable bearing function,and all the bone grafts were completely fused with the tibia without bone resorption,osteonecrosis or other complications.In the last follow-up,for patients with large defects of the tibial plateau,the defect of the tibial plateau was repaired by increasing the osteotomy angle combined with pressure bone grafting,and the transplanted autogenous bone in all patients was completely integrated into the host bone with-out any clinical symptoms.Conclusion:Mortise and tenon bone grafting in repairing tibial plateau de-fect for severe knee osteoarthritis is more compact and stable in the early stage.By further improving the surgical details,the contact gap between bone fragments and main bone is smaller and the scope of adaptation is wider,which is a good surgical method and worthy of promotion.
