Objective To observe the effect of knee arthroscopic enlarged valve resection(AEVR)combined with cyst wall resection(CWR)on popliteal cyst.Methods A retrospective analysis was conducted on the clinical data of 80 patients with popliteal cyst from June 2022 to June 2023.They were divided into two groups based on different surgical methods.Group A received 39 cases of traditional open cystectomy(TOC),while group B received 41 cases of AEVR-CWR.The perioperative indicators,length of hospital stay,pain status,knee joint function,knee joint range of motion,popliteal cyst grading,postoperative complications,and cyst survival were compared between the two groups.Results The surgical bleeding volume,total incidence of postoperative complications,and residual cyst rate at 6 months after surgery in group B were lower than those in group A,the incision length,and hospital stay in group B were shorter than those in group A,surgery time in group B was longer than that in group A,the differences were statistically significant(P＜0.05).After surgery,the visual analogue scale(VAS)of both groups was lower than that before surgery,and group B was lower than group A,the difference was statistically significant(P＜0.05).After surgery,the Lysholm score of both groups were higher than that before surgery,and group B was higher than group A,the knee range of motion of both groups were greater than that before surgery,and group B was greater than group A,the differences were statistically significant(P＜0.05).After surgery,the Rauschning-Lindgren grading of both groups was better than that before surgery,and group B was better than group A,the difference was statistically significant(P＜0.05).Conclusion The combination of AEVR and CWR can reduce surgical bleeding,shorten incision length and hospital stay,alleviate pain,improve knee joint range of motion,knee joint function,and grading of popliteal cysts,reduce the total incidence of postoperative complications and the residual rate of cysts at 6 months after surgery,but the surgery time has been extended.
