| Objective To investigate whether bone graft is needed to fill the defect of the osteotomy end in high tibial osteotomy (HTO).Methods A retrospective analysis was performed on 98 patients who underwent HTO in the Second Affiliated Hospital of Anhui Medical University from June 2019 to March 2022 and met the exclusion criteria, including 50 patients in the bone graft group (9 patients with iliac bone graft, 41 patients with allogeneic bone graft), and 48 patients in the non-bone graft group. The healing degree, correction angle, distraction height, postoperative weight-bearing time and various complications were compared between the two groups. Preoperative and postoperative HKA, MPTA, HSS, VAS, WOMAC knee arthritis index, knee extension-flexion ROM at 1, 3, 6 and 12 months were compared.Results All 98 patients were included in the study and were followed up for 12 to 33 months, with an average follow-up time of (20.2±7.3) months. There were no significant differences in the correction angle, elongation height, HKA and MPTA between the two groups (P>0.05), and there were no significant differences in the healing degree at the last follow-up (P>0.05). The weight-bearing time of the bone graft group was earlier than that of the non-bone graft group (P<0.05). There were no obvious complications in both groups (one case of delayed wound healing in non-bone graft group). Compared with preoperative, HSS score, VAS score, WOMAC knee arthritis index and ROM in the two groups were significantly improved after operation (P<0.05), but there was no difference between the two groups at the same time (P>0.05).Conclusion No bone grafting during HTO has no effect on the clinical effect under indication. |
