ABSTRACT
Objective:To evaluate the radiologic and clinical outcomes of supramalleolar dome osteotomy in the treatment of varus-type ankle arthritis.Methods:From June 2018 to December 2019, 13 patients with varus-type ankle arthritis underwent supramalleolar dome osteotomy at Department of Foot and Ankle Surgery, Beijing Jishuitan Hospital. Of them, 13 (5 males and 8 females) were included in the study. Their average age at surgery was 47.2 years (range, from 16 to 65 years). By the modified Takakura staging for arthritis, 3 cases were stage 2, 4 cases stage 3a and 6 cases stage 3b. Comparisons were made between preoperation and the last follow-up in ankle-hindfoot score of American Orthopedic Foot and Ankle Society (AOFAS), foot function index (FFI), visual analogue scale (VAS), Takakura staging, dorsal extension, plantar flexion, range of motion (ROM), tibial anterior surface angle (TAS), tibial lateral surface angle (TLS), and talar tilt (TT).Results:This cohort were followed up for 12 to 29 months (average, 17.2 months). At the last follow-up, AOFAS score (86.5±8.0), FFI (14.5±1.6), VAS score (1.5±1.0), Takakura staging (2.7±1.3), ROM (39.4°±8.0°), TAS (92.4°±6.0°), TT (3.7°±4.4°) were significantly improved than the preoperative values (68.3±14.4, 43.7±3.0, 4.2±1.4, 3.2±0.8, 43.3°±7.6°, 78.2°±8.3° and 7.0°±5.1°), and dorsal extension (10.9°±4.4°) was significantly smaller than the preoperative value (13.6°±5.1°) (all P<0.05). There were no significant differences between preoperation and the last follow-up in plantar flexion (29.7°±4.6° versus 28.5°±5.2°) or TLS (77.8°±4.5° versus 78.1°±5.3°) ( P>0.05). Conclusions:Supramalleolar dome osteotomy has shown promising short-term clinical efficacy in the treatment of varus-type ankle arthritis. It can significantly relieve pain, improve function, substantially correct deformity and retard progression of arthritis, but it may affect dorsal extension.
