Abstract:Objective To investigate the clinical effect of shoulder arthroscopic rotator cuff repair combined with shoulder three needles in treatment of rotator cuff injury.Methods 86 patients with rotator cuff injury from June 2021 to May 2023 were divided into two groups using a random number table method. The research group received 43 cases of rotator cuff repair under arthroscopy combined with shoulder three needles rotator cuff repair, while the control group received 43 cases of rotator cuff repair under arthroscopy combined with placebo needling. Then compare the pain level, shoulder joint function, and shoulder joint range of motion between the two groups before and 6 months after surgery, and calculate the excellent and good shoulder joint function rates between the two groups at 6 months after surgery, and compare the changes in inflammatory factors between the two groups at before and 4 weeks after surgery.Results 6 months after surgery, the visual analogue scale (VAS) score of both groups was lower than that before surgery, and the VAS score in research group (including the moderate tearing subgroup and the major tearing subgroup) was lower than that of the control group (including the moderate tearing subgroup and the major tearing subgroup), while the American Shoulder and Elbow Surgeons (ASES) score and shoulder joint range of motion were higher than those before surgery, and the ASES score and shoulder joint range of motion in research group (including the moderate tearing subgroup and the major tearing subgroup) were higher than those of the control group (including the moderate tearing subgroup and the major tearing subgroup), the differences were statistically significant (P < 0.05). 6 months after surgery, the excellent and good rate of shoulder joint function in the research group was higher than that in the control group, the difference was statistically significant (P < 0.05). At 4 weeks after surgery, the levels of tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), interleukin-6 (IL-6), and interleukin-8 (IL-8) in both groups were lower than those before surgery, and the research group (including the moderate tearing subgroup and the major tearing subgroup) were lower than those of control group (including the moderate tearing subgroup and the major tearing subgroup), the differences were statistically significant (P < 0.05).Conclusion Arthroscopic rotator cuff repair combined with shoulder three needles can alleviate the pain level of patients with rotator cuff injury, improve shoulder joint function and range of motion, increase the excellent and good rate of shoulder joint function, and reduce inflammatory reaction. It is worthy of clinical application.
