Abstract:
Objective Non-traumatic and posteromedial subchondral osteonecrosis of trochlea tali (NTPSOTT) is a special type of necrosis of the talus , for which early diagnosis and treatment are particularly important .This study investigated the clinical ef-fectiveness of autogeneic cancellous bone transplantation in the treatment of NTPSOTT . Methods We retrospectively analyzed 21 cases of NTPSOTT treated by autogeneic cancellous bone transplantation and evaluated using the Clinical Rating System of the American Orthopedic Foot and Ankle Society ( AOFAS) , Visual Analogue Scale ( VAS) , and X-ray and CT examinations . Results The pa-tients were followed up for 12-26 months and all healed desirably , with the graft well integrated into the surrounding tissue , but no as-similation, collapse of the articular surface , or narrowing of the joint space .The last follow-up visit revealed significantly improved AOFAS score (90.55 ±6.73 vs 50.87 ±11.42, P=0.009) and VAS score (1.32 ±0.81 vs 6.43 ±1.66, P=0.027) as compared with the baseline . Conclusion Autogeneic cancellous bone transplantation is preferable for the treatment of NTPSOTT , which can effectively reduce the pain in the ankle , maintain the joint space , and protect the function of the ankle .
