Abstract:Abstract: Objective To investigate the effect of arthroscopic repair of rotator cuff combined with intraarticular injection of sodium hyaluronate + tranexamic acid + diprospan in the treatment of rotator cuff injury with secondary frozen shoulder. Methods 41 cases of patients with rotator cuff injury complicated with secondary frozen shoulder were analyzed retrospectively in the department of joint surgery in our hospital From August 2015 to may 2017, 12 males and 29 females, aged 42 ~ 68 years (mean 55.5 years), course of disease 6 ~ 11 months. The patient complained of shoulder pain and limited mobility. MRI showed rotator cuff tear.step one is to manipulation release under general anesthesia,Then the arthroscopic release, and according to the shape and size of the rotator cuff tear to choose the corresponding operation of rotator cuff suture.After closing the incision, the glenoid humeral joint was placed in the drainage tube and 20 mg sodium hyaluronate + 10 ml tranexamic acid + 1 ml diprospan was perfused, Drainage tube was placed under the shoulder peak and sodium hyaluronate 20mg + tranexamic acid 10ml was perfused. Finally, According to the situation of bone and rotator cuff tear after operation, the rehabilitation program was designed individually. Results The operation was completed successfully. All incisions healed in stage Ⅰ, One patient was discharged from hospital one month after operation because the pain was not relieved and was hospitalized again for anti-inflammatory and analgesic treatment. no related complications occurred in other cases.The average follow-up time was 9 months,(Visual analogue scale (VAS) vas pain score decreased from 5 ~ 10 points (7.0 ± 1.2) to 0 ~ 3 points (1.1 ± 0.1) after operation. reoperative Shoulder range of motion: external rotation 5 ~ 50°(29.6 ± 13.4)°, anterior flexion 30 ~ 135°(82.8±30.4)°, abduction 30 ~ 140°(83.4 ± 29.4)°; Postoperative: external rotation 25 ~ 60°(51.3 ± 8.6) °, anterior flexion 85 ~ 180°(160.3 ± 22.8)°, abduction 80 ~ 180°(157.1 ± 22.3)°. Conclusions Arthroscopic combined with joint cavity perfusion in the treatment of rotator cuff injury combined with secondary frozen shoulder can effectively alleviate pain, improve joint mobility, accelerate rehabilitation, clinical effect is satisfactory.
