Application of the technique of autologous matrix-induced chondrogenesis in the treatment of patients with osteoarthritis of the first metatarsophalangeal joint

Introduction To date, there is no unified approach to the choice of tactics in surgical treatment of osteoarthritis of the first metatarsophalangeal joint (OA of the first MTP joint). On the other hand, it is known that the technique of autologous matrix-induced chondrogenesis has been successfully used for osteochondral defects in the hip, knee and ankle joints. Therefore, we have proposed to use this technique in the treatment of patients with OA of the first MTP joint. Purpose To study the possibility of surgical treatment of patients with OA of the first MTP joint with the use of chondroplasty utilizing the technique of autologous matrix-induced chondrogenesis, to demonstrate the immediate and mid-term results of such operations. Materials and methods Chondroplasty was performed in 15 patients (16 feet) with OA of the first MTP joint. The examination determined the range of motion in of the first MTP joint; the condition was assessed according to such scales as VAS for pain, AOFAS, FFI. Chondroplasty in of the first MTP joint was performed with the technique of induced chondrogenesis using a collagen matrix. The results of the operations were evaluated after 3, 6 and 12 months. Results As early as 3 months after the operation, there was a marked significant increase in the range of motion and a decrease in pain of the first MTP joint. Moderate positive dynamics were observed after 6 and 12 months. Conclusion The results of the operations showed that chondroplasty of the first MTP joint is an effective method of surgical treatment that provides pain relief and significantly improves the quality of life of patients with OA of the first MTP joint. However, it is necessary to study long-term results.
