Hybrid bone and cartilage transplantation - an innovative technology for the surgical treatment of large osteochondral defects of the knee joint

The article is devoted to the current direction of modern orthopedics - surgical treatment of osteochondritis dissecans of the knee joint. This disease accounts for up to 2% of all diseases of the knee joint and occurs in approximately 30 patients per 100.000 people.Materials and methods: The authors of the article developed the technique of “Hybrid bone and cartilage transplantation”, based on the removal of pathological subchondral bone, its replacement by autologous bone and collagen matrix implantation. Such an operation technique was applied in 27 patients. The article presents the indications and technique of the operation, criteria for evaluating treatment outcomes.Results: treatment outcomes up to 2 years were studied in all 27 patients. Good treatment results were observed in 22 patients. In all cases, high-quality consolidation of bone tissue and regeneration of the cartilaginous surface of osteochondral defects were achieved.Conclusion: The analysis of treatment outcomes for patients after “hybrid osteochondral transplantation” allows the article authors to recommend this technique for widespread use in clinical practice.
