Background: To determine the natural progression of conservatively treated rotator cuff tears, we evaluated changes in radiologic and clinical parameters in patients whose recalcitrant tears were neglected after conservative treatment. Methods: A total of 73 patients with recalcitrant rotator cuff tears in spite of conservative treatment were included in this study. We measured changes in tear size and in the extent of fatty infiltration of the rotator cuff by comparing the initial and final follow-up magnetic resonance imagings (MRIs). To determine factors influencing the change in tear size, we collected the medical history of patients taken at the time of initial admission. Results: The average follow-up period was 20.1 months, and the average increase in tear size across this period was 6.2 mm. In terms of steroid injection, we found that the increases in tear size of the steroid injection group (p=0.049) and of the sub-group that had received more than three steroid injections (p=0.010) were significantly greater than that of the non-steroid injection group. Conclusions: We found that the increase in cuff tear size was on average 6.2 mm across the follow-up period, indicating that neglecting cuff tears may cause them to progress into more severe tears. We also observed that a history of steroid injection might be a possible risk factor for a worse prognosis of cuff tears. Therefore, we suggest that patients with rotator cuff tears and a history of steroid injection are recommended aggressive modes of treatment such as surgery.

Rotator cuff tears commonly affect the shoulder joints. Despite developments in surgical techniques and instrumentation, the treatment of massive rotator cuff tears remains challenging. The problems associated with rotator cuff repairs, such as inferior mechanical properties and high retear rates are yet to be solved. Recently, patch augmentation has been suggested as an alternative treatment because it can reinforce mechanical properties at the initial stage of healing and reduce gap formation. The purpose of this article was to comprehensively summarize the concepts and the consensus surrounding patch augmentation and evaluate the clinical and anatomical outcomes after patch augmentation for massive rotator cuff tears.

Objectives : To evaluate the effects of arthroscopic acromioplasty and debridement for partial thickness articular side rotator cuff tears, Method: We divided 97 patients into 2 groups according to treatment protocol, with both groups having confirmed intra-articular partial tears of the rotator cuff. In group Ⅰ, we debrided the frayed and fibrotic cuff margin while in group II, we performed subacromial decompression in addition to debridement. After the surgery we checked all the patients with the modified UCLA shoulder rating scale. Results: The follow-up observation 12 months after surgery revealed that 44 patients in group I were rated as excellent in 32 cases, good in 10 cases, fair in 1 case, and poor in one case, while 53 patients in group II, were rated as excellent in 38 cases, good in 17 cases, and fair in 2 cases. Twenty-four month after surgery we observed that patients in group I were rated as excellent in 23 cases, good in 16 cases, fair in 4 cases, and poor in 1 case, while patients in group II were rated as excellent in 34 cases, good in 17 cases, and fair in 6 cases. Conclusion: The use of acromioplasty on partial thickness tears of rotator cuff, even in the cases of intra-articular nature, is preferable to the procedure performed without it.

Background: The Korean Shoulder Scoring System (KSS) is a reliable and valid procedure for discriminative assessment of the clinical status of patients with rotator cuff tears. This study evaluates the correlation between the preoperative KSS and factors in patients with rotator cuff tears. Methods: From November 2009 to June 2016, 970 patients who underwent arthroscopic rotator cuff repair were retrospectively evaluated. A total of 490 patients met the study criteria. Preoperative factors included age, sex, symptom duration, mediolateral (ML) and anteroposterior (AP) tear size, acromiohumeral distance (AHD), tangent sign, tendon involvement (type I, supraspinatus; type II, supraspinatus and subscapularis; type III, supraspinatus and infraspinatus; type IV, all 3 tendons), fatty infiltration of rotator cuff muscles (group I, Goutallier stages 0 and 1; group II, Goutallier stages 2, 3, and 4), and KSS. Results: Old age, ML tear size, and AP tear size negatively correlated with the preoperative KSS (p<0.001). AHD showed a positive correlation with the preoperative KSS (p<0.001). A significantly inferior preoperative KSS was found in females and type III tendon involvement (p<0.001). For supraspinatus and infraspinatus, the preoperative KSS of group II fatty infiltration showed a significantly lower score than group I fatty infiltration (p<0.05). Conclusions: A relatively lower preoperative KSS was associated with old age, large tear size, narrow AHD, female, type III tendon involvement, and group II fatty infiltration of the supraspinatus and infraspinatus. Our study indicates that preoperative KSS can be a good measurement for the preoperative status of patients with rotator cuff tears.

Background: This study measured the rate of adrenal insufficiency among rotator cuff tear patients, and determined the roles of steroid treatment and herbal medicine as specific risk factors of adrenal insufficiency. Methods: We prospectively evaluated the 53 patients who agreed to participate in the study and underwent arthroscopic rotator cuff repair due to a chronic full-thickness tear from March 2012 to September 2013. The diagnosis of adrenal insufficieny was made by rapid adrenocortical hormone test before the operation. We collected information regarding their history of steroid and herbal medicine treatment within the last 12 months. Results: The rate of adrenal insufficiency among the rotator cuff tear patients in our study was 18.9% (10 of 53 patients). Steroid treatment (p=0.034), frequency of local steroid injection (p=0.008), and herbal medicine treatment (p=0.02) showed significant association with the risk of adrenal insufficiency. Conclusions: In this study, careful taking of a patient's medical history, such as the use of steroids and herbal medicine, is important when investigating adrenal function before surgery.

목적: 회전근 개 파열의 봉합 가능성은 수술적 치료의 적응증을 정립하는데 매우 중요하다. 저자는 회전근 개의 봉합 가능성 및 치유에 영향을 주는 요소들과 회전근 개 파열의 수술적 치료의 적응증에 대해서 고찰하였다. 대상 및 방법: 회전근 개 파열의 봉합 가능성은 수술적 봉합 가능성과 술 후 회전근 개 파열의 치유 가능성의 측면에서 고려되어야 한다. 회전근 개 파열의 자연 경과에 대한 이해 역시 수술적 치료를 할 것인지 보존적 치료를 할 것인지를 결정하는데 큰 도움을 준다. 결과: 회전근 개의 치유 가능성을 예측하는 세가지 일반적인 범주가 있는데 첫째로 수술적 요소, 생물학적 요소, 환경적 요소이다. 수술의는 수술적 기법을 스스로 선택함으로써 수술적 요소를 제어할 수 있으며, 생물학적 요소는 나이와 급성 외상의 유무, 만성화 정도, 파열의 정도 등을 고려하여 주의 깊게 수술 적응 대상을 선택함으로써, 환경적 요소는 흡연 및 비스테로이드성 소염진통제(nonsteroidal anti-inflammatory drug, NSAID) 사용을 피함으로써 더 좋은 임상 결과를 기대할 수 있다. 결론: 회전근 개 파열의 자연 경과와 봉합 가능성에 대한 정확한 이해는 회전근 개 파열의 수술적 치료의 적응증을 정립하고 만족스러운 임상결과를 얻는데 큰 도움을 줄 수 있다.

Background: The purposes of the study were to examine rotator cuff tendon degeneration with respect to harvesting location, to determine a rationale for debridement of the torn end, and thus, to determine adequate debridement extent. Methods: Twenty-four patients with a full-thickness rotator cuff tear were included in the study. Tendon specimens were harvested during arthroscopic rotator cuff repair from three locations; from torn ends after minimal regularization of fraying (native end group, NE group), from torn ends after complete freshening of the frayed end (freshened end group, FE group), and from the macroscopically intact portion just distal to the musculotendinous junction (musculotendinous junction group, MTJ group). Control samples were harvested from patients admitted for surgery for proximal humerus fracture. Harvested samples were evaluated using a semi-quantitative grading scale. Results: Mean total degeneration scores in the NE group ($13.3{\pm}3.21$), the FE group ($12.5{\pm}2.30$), and in the MTJ group ($10.8{\pm}3.10$) were significantly higher than those in the normal control group ($5.0{\pm}2.87$; all p<0.001). Mean total degeneration score in the NE group was significantly higher than that in the MTJ group (p=0.012), but was not from that of the FE group. Mean total degeneration score in the FE group was not significantly different from that of the MTJ group. Conclusions: Tendon degeneration exists throughout the entire tendon to the macroscopically intact portion of full-thickness rotator cuff tear. Therefore, aggressive debridement to grossly normal appearing, bleeding tendon is unnecessary for enhancing healing after repair.
