Arthroscopic versus mini-open rotator cuff repair: a cohort comparison study.
OBJECTIVE
To critically compare arthroscopic and mini-open rotator cuff repair.


METHODS
Retrospective case control study.


METHODS
Nine patients who had an arthroscopic rotator cuff repair (ARCR) were matched for age, gender, dominance, side of injury, history of trauma, duration of symptoms, and type of rotator cuff injury, with 12 patients who had a mini-open rotator cuff repair (MOR). Comparison included a preoperative and postoperative physical examination as well as a completed Simple Shoulder Test (SST) questionnaire at the latest follow-up at a minimum of 27 months.


RESULTS
Both groups had significant reductions in pain scores (P < .01) and there was no significant difference in preoperative or postoperative active flexion or external rotation between both groups (P > .20). Although the ARCR group showed a significant improvement in strength (P < .01) and the MOR group did not, no patient had less than 4/5 strength. The impingement sign remained positive in 1 MOR patient, but all patients had a negative Jobe's test result. Pain and Tasks assessment by SST questionnaire showed that neither group had night pain or discomfort when using their arms overhead. There were no significant differences in the overall SST scores between groups.


CONCLUSIONS
Because all patients in each group were satisfied with the procedure and there were no objective differences in outcome, we conclude that there is no difference in outcome between ARCR and MOR. Thus, the choice of one approach over the other is best based on surgeon or patient preference.


METHODS
