Keywords: Shoulder joint, joint position sense, rotator cuff tear, isokinetic muscle strength


Objectives: All-arthroscopic surgery and mini-open surgery for repairing rotator cuff tears are widely used and clinically developed. The purpose of our study is to compare the functional results, isokinetic shoulder muscle strength and shoulder position sense of patients who have undergone all-arthroscopic and mini-open surgery to repair their rotator cuff tears.

Material and Methods: The results from 28 patients (20 females and 8 males) with isolated rotator cuff tears were evaluated. Twelve had have all-arthroscopic surgery (ASR) (mean age 54.3 yrs) and 16 had have mini-open surgery (MOP) (mean age 51.5 yrs). Clinical and functional results were compared using the American Shoulder and Elbow Surgeons (ASES), and Disabilities of the Arm, Shoulder and Hand (DASH) indices. Shoulder Muscle Strength and shoulder joint position sense were measured with an isokinetic dynamometer (CSMI Humac Norm, USA).

Results: Mean age of the patients was 52.8 yrs (min-max: 40-67). Mean post-operative ASES and DASH scores of ASR-operated patients were 78 and 18.8, respectively. MOP- implemented patients had mean ASES and DASH scores of 86 and 13.6, respectively. As for functional results, there was no statistically significant difference (p>0.05). For patients who went through either surgery, there were no statistically significant different result in terms of isokinetic shoulder muscle strength (internal rotation, external rotation, adduction, abduction) and joint position sense results (p>0.05).

Conclusion: There were no significant differences between two methods in means of functional outcomes, joint strength and position sense. But, these two methods should be investigated by more comprehensive studies.
