BACKGROUND: Distal tibial tuberosity-high tibial osteotomy is a surgical treatment for knee osteoarthritis, but there is still a lack of clinical studies on its effect on ankle joints. OBJECTIVE: To observe the effects of distal tibial tuberosity-high tibial osteotomy on ankle angle on coronal plane of the radiography of the full length of lower limb in weight loading. METHODS: Data of 40 patients (41 knees) with distal tibial tuberosity-high tibial osteotomy from March 2021 to March 2022 were retrospectively analyzed, including 31 females and 9 males, 20 left knees and 21 right knees, aged 49-75 years, mean (63.44±6.57) years. The radiographic data of the full length of the lower limb in weight loading were collected before, week 2 and week 48 postoperatively. Hip-knee-ankle angle, talar tilt angle, tilt angle of the ankle, tibiocrural angle, and tibial articular surface angle were measured before and after surgery. RESULTS AND CONCLUSION: (1) Hip-knee-ankle angle improved from (-6.24±3.69)° before operation to (2.59±3.49)° week 2 postoperatively and (2.15±3.49)° week 48 postoperatively. The tilt angle of the ankle changed from (-7.90±3.11)° before operation to (-2.51±2.59)° week 2 postoperatively and (-2.46±2.42)° week 48 postoperatively, with statistically significant difference (P < 0.001). (2) There was no significant difference in talar tilt angle, tibiocrural angle, and tibial articular surface angle before and week 2 postoperatively. (3) No significant difference in the angle changes was detected between week 2 and week 48 postoperatively. (4) It is indicated that distal tibial tuberosity-high tibial osteotomy can not only correct genu varus but also improve ankle angle. This result remains stable after 48 weeks of weight-bearing activities. [ABSTRACT FROM AUTHOR] |
