Abstract:Objective To observe the effects of simultaneous arthroscopic lysis of shoulder joint adhesions and the rotator cuff repair on muscle strength and function recovery in patients with rotator cuff injury and shoulder joint adhesion. Methods Sixty-four patients with rotator cuff injury combined with shoulder joint adhesion from December 2014 to December 2016 were selected as study objects and divided into study group (n=33) and control group (n=31) according to different treatment method. The simultaneous arthroscopic lysis of shoulder joint adhesions with rotator cuff repair was performed in study group, and two-stage rotator cuff repair was conducted after 3-month shoulder function training and surgery for relaxation in control group. The operative situation, shoulder mobility, muscle strength of affected limbs, American Shoulder and Elbow Surgery Association (ASES) score and visual analogue scale (VAS) were observed in two groups.? Results The operation was successfully completed in study group. In control group, 23 cases underwent two-stage rotator cuff repair after function training, and 8 cases received surgery ahead of time because of unbearable pain. After postoperative 3-, 6-, 12-month, the activity degrees of anteflexion, abduction, external rotation and internal rotation in both two groups gradually increased compared with those before operation (P<0.05), and they were significantly lower in study group than those in control group only 3 months after operation (P<0.05). At 12 months after operation, the muscle strength of anteflexion, external rotation, internal rotation and ASES scores of affected limbs in both two groups were significantly higher than those before treatment, and VAS score was significantly lower than that before treatment (all P<0.05). However, there were no statistical differences in them between two groups (all P>0.05).? Conclusion Compared with two-stage rotator cuff repair, simultaneous arthroscopic lysis of shoulder joint adhesions and rotator cuff repair for treatment of patients with rotator cuff injury and shoulder joint adhesion can also effectively improve the muscle strength and promote the recovery of shoulder function.
