[Effect of total arthroscopic rotator cuff repair on pain degree and complications of elderly patients with rotator cuff injury within 72 hours after operation].

Objective: To analyze the clinical effect of rotator cuff repair and small incision rotator cuff repair under the total arthroscopy in elderly patients with rotator cuff injury.

Methods: A total of 60 elderly patients with rotator cuff injury from January 2017 to November 2018 were selected as the research objects, including 37 males and 23 females;aged from 61 to 77 years old with an average of (63.45±12.34) years old;disease duration ranged from 6 to 12 months, with an average of (5.32±1.02 ) months;29 cases on the left side and 31 cases on the right side. Among them, 30 patients underwent total arthroscopic rotator cuff repair (observation group), 30 patients underwent small-incision rotator cuff repair(control group). The scores of University of California, Los Angeles(UCLA) shoulder rating scale, before and after surgery in the two groups were observed and recorded. The American Shoulder and Elbow Surgeons(ASES) score, Constant-Murley score, shoulder flexion range of motion, external rotation range of motion, abduction range of motion, visual analogue scale(VAS) within 72 hours after surgery, as well as the complcations were compared.

Results: The postoperative UCLA score, ASES score and Constant-Murley score between two groups were significantly higher than those before operation (<0.05). There was no significant difference in postoperative UCLA, ASES and Constant-Murley score between two groups (>0.05). The shoulder flexion range of motion, external rotation range of motion and abduction range of motion between two groups were significantly higher than those before operation (<0.05). There was no significant difference between the two groups after operation (>0.05). The VAS at 24, 48 and 72 h after operation in observation group were significantly lower than those in control group (<0.05). The total incidence of complications in observation group(13.33%, 4/30) was sinificantly lower(<0.05)than that in control group(33.33%, 10/30).

Conclusion: Total arthroscopic rotator cuff repair and small incision rotator cuff repair can improve the shoulder function after rotator cuff injury in elderly, but the degree of pain and complications within 72 hours after total arthroscopic rotator cuff repair are significantly better than small incision rotator cuff repair, which can be selected according to the clinical situation and needs of patients.
