Methods: 36 patients aged from 21 to 67 years were treated. In 27 patients (group 1), the ankle arthroscopy was performed with the removal of free osteochondral bodies, debridement, tunneling or microfractioning in the affected area followed by the use of PRP (fig.1). In 9 patients (group 2), the above procedures were performed with arthrotomy and osteotomy of the medial malleolus and osteochondral autotransplantation was performed (fig.2). In the autotransplantation, the defect place was filled with PRP. The functional condition of the ankle was assessed by VAS and AOFAS before treat- ment, 3 and 12 months after treatment. 
Results: In the group of arthroscopic treatment, after 3 months, the pain syndrome in VAS decreased from 6.4 ± 0.4 to 2.3 ± 0.3, and after 12 months to 1.7 ± 0.2. Ac- cording to AOFAS, the function of the joint increased from 35 ± 5.4 points to 73 ± 4.7 points in 3 months, and to 89 ± 2.9 in 12 months. 
In the group of patients with osteochondral autotransplanta- tion, the pain with VAS before treatment was 8.1 ± 0.6, 3 months after treatment, the pain syndrome decreased to 3.6 ± 1.8, and after 12 months to 2.1 ± 0.3. The joint function of AOFAS from 34 ± 2.8 points after 3 months increased to 67 ± 4.1, and after 12 months it was 83 ± 2.9. 
Conclusions: A differentiated approach to the choice of treatment tactics for patients with post-traumatic osteochondral ankle defects and the use of regenerative technologies in the system of treatment, allowed to obtain good results in the treatment of patients with minimal grade.
