Abstract：【Objective】To compare the efficacy of two kinds of PEEK suture anchor in arthroscopic rotator cuff repair. 【Methods】A total of 34 patients with rotator cuff tears who received arthroscopic rotator cuff repair in Hunan Provincial People's Hospital (the First Affiliated Hospital of Hunan Normal University) from September 2017 to March 2019 were randomly divided into the observation group and the control group, with 17 patients in each group. In the observation group, PEEK suture anchor nail from the Delta Medical's PEEK suture anchor was used during the operation; The control group was treated with PEEK suture anchor of the Smith & Nephew. The clinical effective rate, intact rate of rotator cuff, VAS score, range of motion of shoulder joint and incidence of complications were compared between the two groups. 【Results】 Six months after operation, the clinical effective rate in the observation group was 76.5% (13/17), which had no significant difference compared with 62.5% (10/16) in the control group (P>0.05). Three months after operation, MRI showed that 15 cases (88.2%) in the observation group had intact rotator cuff, 2 cases (11.3%) had Sugaya Grade Ⅳ incomplete rotator cuff, and 16 cases (100%) in the control group had intact rotator cuff; Six months after operation, the rotator cuff was intact in 15 cases (88.2%) in the observation group, while only 13 cases (81.3%) in the control group; Sugaya Ⅴ type complete re tear did not occur 3 months and 6 months after operation in both groups. There was no significant difference in VAS scores between the two groups before operation under rest and active activity (P>0.05); In the passive activity state, the preoperative VAS score of the observation group was lower than that of the control group (P<0.05). There was no significant difference in VAS scores between the two groups at 3 and 6 months after operation under resting and active activities (P>0.05); In the passive activity state, the VAS scores of the observation group at 3 and 6 months after operation were significantly lower than those of the control group (P<0.05). The shoulder joint range of motion of active flexion and abduction in both groups was significantly improved 6 months after operation (P<0.05); The range of motion of active and passive abduction and external rotation shoulder joints in the observation group before operation was significantly higher than that in the control group (P<0.05), and the range of motion of passive abduction and external rotation shoulder joints 6 months after operation was significantly higher than that in the control group (P<0.05). There was no loosening, displacement or breakage of the anchor in both groups 2 weeks and 3 months after operation; There were no complications such as infection, vascular or nerve injury. 【Conclusions】 Two kinds of PEEK suture anchors have good efficacy in arthroscopic rotator cuff repair, improving shoulder joint function and relieving pain. However, the PEEK suture anchor of Demei Company has lower cost and is suitable for patients with rotator cuff tear, especially low-income people.
