PURPOSE: Arthroscopic techniques tend to become the gold standard in rotator cuff repair. However, little data are reported in the literature regarding the improvement of postoperative outcomes and re-tear rate relative to conventional open surgery. The aim of this study was to compare clinical outcomes and cuff integrity after arthroscopic versus open cuff repair. METHODS: We prospectively assessed clinical outcomes and cuff integrity after an arthroscopic or open rotator cuff repair with a minimum follow-up of 12 months...

Rotator cuff tears are one of the primary causes of shoulder pain and dysfunction in the upper extremity accounting over 4.5 million physician visits per year with 250,000 rotator cuff repairs being performed annually in the United States. While the tear is often considered an injury to a specific tendon/tendons and consequently treated as such, there are secondary effects of rotator cuff tears that may have significant consequences for shoulder function. Specifically, rotator cuff tears have been shown to affect the joint cartilage, bone, the ligaments, as well as the remaining intact tendons of the shoulder joint...

Medial collateral ligament tears usually will be treated through non-surgical methods, but, in some cases such as those with tears at the distal insertion where the reduction could be blocked by the pes anserine tendons (Stener-like lesion), surgery will be performed. Here, we present a surgical technique in such cases. In this retrospective case series, we describe six patients diagnosed with Stener-like lesion based on clinical evaluation and imaging results. In the one-year follow-up visit, there was no complaining of pain or joint instability and full range of motion and negative valgus stress test were reported in all cases...

Introduction: Partial thickness rotator cuff tears (PTRCTs) are common, with an incidence between 17% and 37%, and a high prevalence in throwing athletes. Different surgical procedures are suggested when partial tears involve the articular portion of the rotator cuff, including arthroscopic debridement of the tear, debridement with acromioplasty, tear completion and repair, and lately transtendon repair. This systematic review describes the transtendon repair and examines indications, contraindications, complications and clinical outcome...

Isolated dorsoradial capsule injuries of the thumb metacarpophalangeal joint are different from those associated with collateral ligament disruption. Early suspicion of this rare injury is important because, if overlooked, ulnarward subluxation of extensor pollicis longus tendon can develop. Functionally, active thumb extension becomes impaired, and over the long term, a thumb Boutonniere's deformity becomes established. Joint hypermobility/instability may predispose to this injury. The 2 cases presented illustrate this through anatomic differences...

BACKGROUND: Fatty degeneration of the rotator cuff muscles is associated not only with postoperative retear but also with postoperative muscle weakness; therefore, fatty changes in the muscles may affect the clinical outcome even in patients with these tears who have intact tendons after arthroscopic rotator cuff repair (ARCR). PURPOSE: To evaluate the effect of fatty infiltration on the clinical outcome in patients with intact tendons after arthroscopic repair of large/massive cuff tears...

Rotator cuff tear is a common orthopedic condition. Metalloproteinases (MMP) and their inhibitors (TIMP) seem to play a role in the development of joint injuries and in the failure of tissue healing. However, the mechanisms of regulation of gene expression in tendons are still unknown. Epigenetic mechanisms, such as DNA methylation and microRNAs regulation, are involved in the dynamic control of gene expression. Here, the mRNA expression and DNA methylation status of MMPs (MMP1, MMP2, MMP3, MMP9, MMP13, and MMP14) and TIMPs (TIMP1-3) and the expression of miR-29 family members in ruptured supraspinatus tendons were compared with non-injured tendons of individuals without this lesion...

A rotator cuff tear is a common injury in athletes and workers who repeatedly perform overhead movements, and it is not uncommon for this demographic to return to activity shortly after treatment. A biceps tenotomy is often performed in the presence of a rotator cuff tear to help reduce pain and improve joint function. However, the effect of this procedure on the surrounding tissues in the glenohumeral joint is unknown. Therefore, the purpose of this study was to investigate the effect of a biceps tenotomy in the presence of a supraspinatus rotator cuff tear followed by overuse activity on ambulatory function and mechanical and histologic properties of the remaining rotator cuff tendons and glenoid cartilage...

BACKGROUND: The treatment of massive irreparable rotator cuff rupture has still no consensus among shoulder surgeons. It is assumed that symptomatic rotator cuff tendon rupture is accepted as irreparable if retraction amount of tendon is Patte stage 3 on MRI; degree of fatty atrophy is Goutallier stage 3 or 4; narrowing of acromiohumeral distance is lesser than 7 mm and excursion of tendon to repair has decreased and patient has severe pain. Biodegradable balloon is one of the newest methods for the treatment of irreparable massive rotator cuff ruptures...

Tears in the annulus fibrosus (AF) of the intervertebral disc can result in herniation of the nucleus pulposus and progressive disc degeneration. Understanding AF failure mechanics is particularly important as research moves towards developing biological repair strategies for herniated discs. Unfortunately, failure mechanics of fiber-reinforced tissues, particularly those with fibers oriented off-axis from the applied load, is not well understood. Therefore, the objective of this study was to investigate the effectiveness of mid-length notch geometries in producing repeatable and consistent tissue failure within the gauge region of AF mechanical test specimens...

BACKGROUND: Rotator cuff muscle fatty degeneration after a chronic tendon tear is an irreversible pathologic change associated with poor clinical outcomes of tendon repair, and its exact pathogenesis remains unknown. We sought to investigate the role of transplanted bone marrow cells in the development of fatty degeneration, specifically in adipocyte accumulation, using a mouse model. METHODS: Fourteen mice were divided into 2 bone marrow chimeric animal groups: bone marrow transplantation (BMT) group and reverse BMT group...
