Comparison of the effect of total arthroscopic surgery and arthroscopic debridement combined with posterior open resection
To compare the clinical efficacy of total arthroscopic surgery and arthroscopic debridement combined with posterior open resection in the treatment of popliteal cysts. Methods Sixty patients with popliteal cyst were selected and randomly divided into two groups, 30 cases in each group. The observation group was treated with double posteromedial approach total arthroscopic surgery, and the control group was treated with arthroscopic debridement combined with posterior open resection. The clinical indicators, VAS score and Lysholm score of knee joint function before and after surgery, the incidence of complications, and the recurrence of six months after surgery were compared between the two groups. Results The operation time and total length of incision in the observation group were shorter than those in the control group, and the blood loss was less than that in the control group (all P<0.05). After operation, the VAS scores of the two groups of patients were lower than those before operation, and the Lysholm scores were higher than those before operation. The postoperative VAS scores of the observation group were lower than those of the control group, and the Lysholm scores were higher than those of the control group (all P<0.05). Six months after the operation, there were 2 cases of cyst recurrence in the control group, and no recurrence in the observation group, and there was no significant difference between the groups (P>0.05). No neurovascular injury, infection, joint adhesion and other complications occurred in both groups. Conclusion Double posteromedial approach total arthroscopic surgery and arthroscopic debridement combined with posterior open resection can effectively treat popliteal cysts. However, the double posteromedial approach arthroscopic surgery has a more significant effect, with smaller surgical incision, shorter operation time, less intraoperative blood loss, and faster postoperative recovery. It is a surgical method more worthy of clinical promotion.
