Abstract:

Objective　To observe, evaluate, and analyze the clinical effects of different arthroscopic operations in the treatment of patients with osteoarthritis and popliteal cyst. Methods　A total of 40 patients with osteoarthritis and popliteal cyst admitted to Department of Orthopedics, Yangjiang People's Hospital from July 2021 to March 2022 were selected and divided into a control group and an observation group according to the operations, with 20 cases in each group. There were 9 males and 11 females in the control group; they were (49.03±8.01) years old. There were 10 males and 10 females in the observation group; they were (48.91±7.59) years old. The control group were treated through the single posterior medial arthroscopic approach by valvulotomy and internal drainage, and the observation group through double posterior medial arthroscopic approaches by joint cleaning and popliteal cyst resection. The incidences of complications such as incision infection, joint infection, and vascular and nerve injury and patient satisfaction after the operation, the scores Visual Analogue Scale (VAS) and knee joint function and Rauschning-Lindgren grades before and after the operation, and the recurrence rates were compared between the two groups. Independent sample t and χ² tests were applied. Results　The incidence of postoperative wound infection, joint infection, and vascular and nerve injury in the observation group was significantly lower than that in the control group [10.00%(2/20) vs. 40.00%(8/20)], with a statistical difference (χ²=3.333, P<0.05). The VAS scores 3, 6, and 9 months after the surgery were significantly lower than those before the treatment in both groups (all P<0.05), and the scores in the observation group were significantly lower than those in the control group (all P<0.05). The knee function scores 3, 6, and 9 months after the surgery were significantly higher than those before the treatment in both groups (all P<0.05), and the scores in the observation group were significantly higher than those in the control group (all P<0.05). There were no significant changes in the Rausning-Lindgren grading in the two groups between before surgery and 3, 6, and 9 months after the surgery (all P>0.05); there were no statistical differences in the Rausning-Lindgren grading between the two groups at the corresponding time points (all P>0.05). After 12 months' follow-up, the recurrence rate of in the observation group was significantly lower than that in the control group [5% (1/20) vs. 20% (4/20)], with a statistical difference between the two groups (P<0.05). The satisfaction of the observation group was higher than that of the control group [95.00% (19/20) vs. 80.00% (16/20)], with a statistical difference (P<0.05). Conclusion　Joint clearance and popliteal cyst resection through double posterior medial arthroscopic approaches in the treatment of patients with osteoarthritis and popliteal cyst can effectively reduce the incidence of complications, and the knee function recovery effect is more satisfactory, with the advantage of a low recurrence rate and high patient satisfaction, so it is worthy of clinical promotion and application.
