Hybrid bone and cartilage transplantation - an innovative technique for surgical treatment of osteochondritis dissecans of the knee joint

The article is devoted to the surgical treatment of osteochondritis dissecans of the knee joint. This disease accounts for up to 2% of all diseases of theknee joint and occurs in approximately 30 patients per 100.000 people. Materials and methods: The authors ofthe article developed the technique of“Hybrid bone-cartilage transplantation” based on the replacement of pathologicallyaltered subchondral bone with a healthy, spongy autologous bone and collagen membrane implantation. This technique of operation was applied in 31 patients.The article presents indications, contraindications, surgery technique, criteria for evaluating treatment outcomes. A series of clinical cases described confirmsthe high efficiency of this surgical technique. Results: treatment outcomes up to 2 years were studied in all 27 patients. Good treatment results were observed in 26 patients. In all cases, good regenerationof the osteochondral defect was achieved. Conclusion: The analysis oftreatment outcomes for patients after “hybrid osteochondral transplantation” allows the article authors to recommend this techniquefor widespread use in clinical practice.
