BACKGROUND The prevalence of rotator cuff repair continues to rise, with a noted transition from open to arthroscopic techniques in recent years. One reported advantage of arthroscopic repair is a lower infection rate. However, to date, the infection rates of these 2 techniques have not been directly compared with large samples at a single institution with fully integrated medical records. PU...

Arthroscopic rotator cuff repair is being performed by an increasing number of orthopaedic surgeons. The principles, techniques, and instrumentation have evolved to the extent that all patterns and sizes of rotator cuff tear, including massive tears, can now be repaired arthroscopically. Achieving a biomechanically stable construct is critical to biologic healing. The ideal repair construct mus...

Rotator cuff tear has been a known entity for orthopaedic surgeons for more than two hundred years. Although the exact pathogenesis is controversial, a combination of intrinsic factors proposed by Codman and extrinsic factors theorized by Neer is likely responsible for most rotator cuff tears. Magnetic resonance imaging remains the gold standard for the diagnosis of rotator cuff tears, but the ...

OBJECTIVES All-suture anchors are increasingly used in rotator cuff repair procedures. Potential benefits include decreased bone damage. However, there is limited published evidence for the relative strength of fixation for all-suture anchors compared with traditional anchors. MATERIALS AND METHODS A total of four commercially available all-suture anchors, the 'Y-Knot' (ConMed), Q-FIX (Smith ...

For the past few decades, the repair of rotator cuff tears has evolved significantly with advances in arthroscopy techniques, suture anchors and instrumentation. From the biomechanical perspective, the focus in arthroscopic repair has been on increasing fixation strength and restoration of the footprint contact characteristics to provide early rehabilitation and improve healing. To accomplish t...

BACKGROUND Rehabilitation and overuse of the shoulder after rotator cuff repair are a concern in patients with comorbid disability in other extremities. Improvement of outcomes can be hampered in this situation. This study was to describe the clinical outcomes of rotator cuff repair in patients with comorbid disability in other extremities. METHODS In two tertiary institutions, 16 patients wi...

The formation of fibrocartilage at the healing site following a rotator cuff tear repair is a major problem in the field of tendon‑bone healing. The present study aimed to enhance the healing of the tendon‑bone interface following rotator‑cuff tear repair by the interposition of hydroxyapatite (HA) encapsulated with transforming growth factor β1 (TGFβ1). Using an acute rotator cuff repair model...

BACKGROUND Recurrent defects after open and arthroscopic rotator cuff repair are common. Double-row repair techniques may improve initial fixation and quality of rotator cuff repair. PURPOSE To evaluate the load to failure, cyclic displacement, and anatomical footprint of 4 arthroscopic rotator cuff repair techniques. HYPOTHESIS Double-row suture anchor repair would have superior structural...

Tendon-to-bone healing after rotator cuff repair surgery has a failure rate of 20%-94%. There has been a recent interest to determine the factors that act as determinants between successful and unsuccessful rotator cuff repair. Vitamin D level in patients is one of the factors that have been linked to bone and muscle proliferation and healing, and it may have an effect on tendon-to-bone healing...

BACKGROUND Arthroscopic rotator cuff repair is described as being a successful procedure. These results are often derived from clinical general shoulder examinations, which are then classified as 'excellent', 'good', 'fair' or 'poor'. However, the cut-off points for these classifications vary and sometimes modified scores are used.Arthroscopic rotator cuff repair is performed to improve quality...
