Abstract: ［Abstract］ Objective〖HTSS〗To explore the efficacy of cystic wall sclerotherapy combined with arthroscopic treatment of popliteal cyst and its impact on prognosis.
〖HTH〗〖WTHZ〗Methods〖HTSS〗Seventy cases of popliteal cyst were selected as research subjects. The patients were divided into observation group(n=38) and control group(n=32) according to the treatment method. The observation group was treated with cystic sclerosis combined with arthroscopy, and the control group was treated with arthroscope. The therapeutic effects of the two groups were observed, the Visual Angalogue Scale(VAS) scores and Lysholm scores of the two methods were evaluated. Logistic regression was used to analyze the risk factors of postoperative recurrence.
〖HTH〗〖WTHZ〗Results〖HTSS〗After treatment, the VAS scores of the two groups showed a downward trend, the Lysholm score showed an upward trend, and the observation group showed significant changes. the total rate of observation group was significantly higher than that of the control group(P＜0.05). the recurrence rate of the observation group after 5 years was lower than that of the control group(P＜0.05), the single factor analysis and multivariate analysis showed that operative time ≥1 h, postoperative infection, and lobulated cyst were independent risk factors for postoperative recurrence(P＜0.05).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗The long-term curative effect of cystic wall sclerotherapy combined with arthroscopy for the treatment of arthroscope is better, and the recurrence rate is lower, for patients with operation time ≥1 h, postoperative infection and lobulated cyst should be alert to postoperative recurrence.
