Chronic anterior dislocation of the glenohumeral joint often leads to functional impairment and pain. Duration of dislocation is correlated with complications, and this injury is traditionally treated with an open procedure. A right-hand - dominant woman in her late 70s presented with traumatic chronic anterior dislocation of the glenohumeral joint. Her physical exam and imaging studies were consistent with anterior shoulder dislocation, a large Hill-Sachs deformity, and rotator cuff and anterior labral tears. A shoulder reduction under anesthesia was performed followed by an arthroscopic double-row rotator cuff repair. In addition, a labral repair was performed via percutaneously inserted suture anchors. Following this treatment, stability was restored to the glenohumeral joint. The patient progressed well with physical therapy and, at 1-year follow-up, the patient had returned to all routine activities pain-free. Arthroscopic repair of chronic primary traumatic anterior shoulder dislocations requiring surgical treatment is a valuable alternative to open procedures and should be considered in higher-functioning elderly patients. Percutaneous suture anchor placement minimizes trauma to an already pathologic rotator cuff and joint capsule.
