Abstract:Objective To analyze the effects of Mason-Allen single-row technique and modified compression double-row suture on arthroscopic repair of rotator cuff tears.Methods The 96 patients with rotator cuff tears admitted to Huangshi Hospital of Traditional Chinese Medicine from April 2021 to September 2023 were selected. They were divided into two groups based on different treatment methods, where 46 patients in the control group were treated with the Mason-Allen single-row technique and 50 patients in the observation group underwent the modified compression double-row suture. The outcomes of the two groups were compared.Results At 6 months postoperatively, the improvements in shoulder forward flexion, internal rotation, abduction, external rotation, and the muscle strength ratio in the observation group were all greater than those in the control group (P < 0.05). The differences of the Constant-Murley scores, ASES scores and SST scores before and 6 months after surgery in the observation group were higher than those in control group (P < 0.05). At 1 month postoperatively, the observation group showed a greater decrease in VAS scores and a greater increase in UCLA scores compared to the control group (P < 0.05). The Sugaya classification outcomes in the observation group were better than those in the control group (P < 0.05). The complication rate of the observation group was lower than that of the control group (P < 0.05). The operative duration of the observation group was longer than that of the control group (P < 0.05).Conclusions Compared with the Mason-Allen single-row technique, the modified compression double-row suture for arthroscopic repair of rotator cuff tears can more effectively alleviate pain, reduce the incidence of rotator cuff re-tear and complications, and improve the shoulder range of motion and muscle strength of patients.
