Abstract:
OBJECTIVE:To evaluate the short-term efficacy of proximal fibula osteotomy in the treatment of knee osteoarthritis, and to analyze the effect of osteotomy on the tension of the lateral knee soft tissue of patients and verify the reliability of the Arch string theory.
METHODS:A total of 71 patients with varus knee osteoarthritis from December 2019 to March 2022 were included, 3 patients dropped out, and 68 patients completed all trials, collected 27 males and 41 females, aged from 51 to 79 years old, with an average of (68.0±7.0 ) years old. The follow-up time ranged from 4 to 12 weeks, with an average of (3.76±1.94) weeks. After admission, the patient underwent Proximal fibula osteotomy, and the tension of lateral knee soft tissue, visual analogue scale (VAS) of pain, the western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and other indicators were recorded before surgery and 1 month after surgery in the weight-bearing state.
RESULTS:According to the VAS, the curative effect of a single index was evaluated by referring to the score before and after treatment by Bao Zongzhao. Thirty seven cases were markedly effective, 27 cases were effective, and 4 cases were ineffective. After surgery, 3 patients presented with weakness of dorsalis pedis extension and 1 presented with paresthesia of dorsalis pedis, which disappeared after symptomatic treatment . The VAS and WOMAC score at 1 month after operation were lower than those before operation, and the differences were statistically significant(P<0.001). The tension of lateral knee soft tissue 1 month after operation was lower than that before operation, and the difference had statistical significance(P<0.001).
CONCLUSION:Proximal fibula osteotomy is safe and effective in the treatment of varus knee osteoarthritis in the short term. One month after osteotomy, the tension of lateral knee soft tissue increases under weight-bearing state, but the long-term changes still need further observation and follow-up.
