Purpose
The objective of this study is to assess tendon integrity, shoulder function and subscapularis (SCP) power in comparison to the contralateral normal shoulder after arthroscopic SCP repair using the SICK stitch technique.
Methods
This study assessed 32 patients with arthroscopically repaired SCP lesions. The mean age was 63.3years. All patients were assessed with a clinical examination and ultrasound pre and postoperatively. Shoulder function was evaluated using specific clinical tests and established scoring systems. The muscular strength was measured using an Isoforce Control EVO2 device in two positions for SCP (standing and sitting).
Results
At a mean follow up of 18 months n=30 patients showed significantly improved range of motion and clinical scores (pre, post), Constant score (39.2, 66.7), subjective shoulder test (3.5, 92.32), subjective shoulder value (46.6, 88.2) and disabilities of arm, shoulder and hand score (69.3, 34). All tendons showed full integration in ultrasound and there was no significant difference for lesion size or additional SSP lesion. In comparison to the contralateral side a good restoration of power was observed.
Conclusions
After arthroscopic repair of the subscapularis tendon using the SICK-stich technique, patients show a good restoration of shoulder function and power accompanied by good patient satisfaction. Additionally treated lesions did not significantly affect the surgical outcome.
