Purpose: Proprioceptive function has been known to be important to shoulder stability. However, the function in rotator cuff tear patients is rarely investigated. The purpose of current study is to report the proprioceptive function in rotator cuff tear patients and to analyze the proprioceptive function regarding the tear size and the presence of subscapularis tear. Materials and Methods: Between 2011 and 2012, total 76 patients (male 28 and female 48) were recruited and average age was 61.7 years old (range, 38~76). Preoperatively, joint position senses in internal and external rotation were measured for proprioceptive function testing by method of active re-positioning technique. The absolute difference from set point was measured. Proprioceptive function was further analyzed according to tear size of rotator cuff, the presence of subscapularis tear, visual analogue scale of pain, shoulder functional score (American society of elbow and shoulder score), and ranges of motion in shoulder. Results: The absolute difference for external rotation was $4.9^{\circ}{\pm}2.9^{\circ}$, in normal joint and $4.9^{\circ}{\pm}3.0^{\circ}$for involved joint in rotator cuff tear patients. This difference was not significant statistically (p=0.87). The absolute difference for internal rotation was $4.0^{\circ}{\pm}2.7^{\circ}$in normal joint whereas $4.8^{\circ}{\pm}3.7^{\circ}$ for involved joint showing statistically significant difference (p=0.043). There was some trend that the proprioceptive function of internal rotation was more impaired in the bigger tear size group (more than medium tear) compared to the smaller tear size group (partial thickness and small tear, 5.0 vs. 4.0, p=0.061). The impairment of internal rotation proprioception was also accentuated in patients with subscapularis tear (4.8 vs. 4.0, p=0.065). The proprioceptive function of internal rotation was decreased when the pain visual analogue scale was increased (5.2 vs. 4.0 p=0.04), shoulder functional score was decreased (6.1 vs. 4.2, p=0.005), or range of motion in shoulder joint was restricted (5.3 vs. 3.7, p=0.041). Conclusion: The deficit of proprioceptive function was observed in rotator cuff tear patients. Proprioception for internal rotation was impaired in patients with the bigger tear size and subscapularis tear. Pain, shoulder function score, and range of motion were also shown to be related with the deficit in proprioceptive function.

Purpose : To evaluate the diagnostic efficiency of the subacromial bursoscopy with glenohumeral air infusion technique for detection of the full thickness tear which we used to think as a partial thickness tear, because it was hidden by bursal tissue. Materials and methods : We chose 65 cases and divided them into 2 groups. The group I was 18 cases with partial thickness rotator cuff tears on glenohumeral arthroscopic evaluation, and the group 2 was 37 cases with full thickness rotator cuff tears which were repaired. We inflated the glenohumeral Joint with 50-100ml of air and observed air bubble leakage simultaneously on bursoscopy. Results : In group I, we could detect air leakage in 3 cases and found that it was full thickness tear. In group II, 2 cases revealed too much air leakage proved that it was incomplete repair and was in need of additional suture. Conclusion : Air infusion technique is though to be a valuable method in differentiation between the partial and full thickness tear and for evaluation of the security of the repair.

We verified reason of pain by rotator cuff disease using shoulder sonography and found a correlation between shoulder pain and stress. To find out the accuracy of sonographic prediction of rotator cuff disease among the patients with shoulder pain we surveyed 184 patients in S hospital in Seoul Korea between January to October 2012. These patients were previously diagnosed with the torn rotator cuff, adhesive capsulitis and impingement syndrom with shoulder pain. In most times, the rotator cuff disease was diagnosed among the physical workers who use shoulder excessively and also in the women in their 50~60 years of age(144 patients, 78.3%). There were significant correlation between rotator cuff disease and the stress of pain, between sonographic prediction and pain(p<.05). There were significance between shoulder pain and stress in daily life according to result for survey of BEPSI-K(p<.05).

With increased development of patch graft, the number of repair using patch graft in massive rotator cuff tear has increased. Understanding characteristics of various patch graft might be helpful for selection of type of patch, and to improve the outcomes for the treatment of massive rotator cuff tears using patch grafts. Therefore, this paper reviews various studies dealing with clinical outcomes of rotator cuff repair using diverse patch grafts in massive rotator cuff tears.
