Does Additional Biceps Augmentation Improve Rotator Cuff Healing and Clinical Outcomes in Anterior L-Shaped Rotator Cuff Tears? Clinical Comparisons With Arthroscopic Partial Repair.

Background: The repair of anterior L-shaped tears is usually difficult because of the lack of anterior rotator cuff tendon to cover the footprint. The biceps tendon is usually exposed from the retracted anterolateral corner of the torn tendon and can be easily used to augment rotator cuff repair. Hypothesis/Purpose: This study compared the clinical outcomes of the biceps augmentation technique with those of partial tendon repair for the arthroscopic treatment of large anterior L-shaped rotator cuff tears to evaluate the role of additional biceps augmentation in tendon healing.

Comparison of Intra-articular Findings and Clinical Features Between Patients With Symptomatic Anterior Instability After Recurrent Shoulder Subluxation and Dislocation.

Purpose: The purpose of this study was to compare the prevalence of concomitant intra-articular pathologies and clinical manifestations after arthroscopic stabilization between patients with symptomatic anterior instabilities following recurrent shoulder subluxations and dislocations.

Methods: Among patients who underwent arthroscopic stabilization, 28 patients who experienced shoulder subluxations (subluxation group, 26.7 ± 1.

Clinical outcomes of non-operative treatment for patients presenting SLAP lesions in diagnostic provocative tests and MR arthrography.

Purpose: In the present prospective study, the functional outcomes of non-operative treatment were evaluated in patients aged between 30 and 45 years presenting SLAP lesion in diagnostic provocative tests and magnetic resonance (MR) arthrography.

Methods: Forty-six patients with a symptomatic SLAP lesion who participated in recreational level of sports were prospectively enroled. SLAP lesion was diagnosed using combinations of several clinical tests and MR arthrography findings.

Efficacy of a Subacromial Corticosteroid Injection for Persistent Pain After Arthroscopic Rotator Cuff Repair.

Background: Corticosteroid injections have been widely used for reducing shoulder pain. However, catastrophic complications induced by corticosteroid such as infections and tendon degeneration have made surgeons hesitant to use a corticosteroid injection as a pain control modality, especially during the postoperative recovery phase.

Purpose: To determine the effectiveness and safety of a subacromial corticosteroid injection for persistent pain control during the recovery period and to analyze the factors causing persistent pain after arthroscopic rotator cuff repair.

Intra-articular lesions and their relation to arthroscopic stabilization failure in young patients with first-time and recurrent shoulder dislocations.

Background: This study aimed to compare the frequency of intra-articular lesions between young patients with first-time shoulder dislocations and those with recurrent shoulder dislocations and to assess the correlation between intra-articular lesions and failure of arthroscopic stabilization.

Methods: The study enrolled 33 patients who underwent arthroscopic Bankart repair after first-time shoulder dislocation before the age of 30 years. There were 89 age-matched patients who were treated arthroscopically for recurrent dislocation included as a control group.

Recovery of Muscle Strength After Intact Arthroscopic Rotator Cuff Repair According to Preoperative Rotator Cuff Tear Size.

Background: The recovery of muscle strength after arthroscopic rotator cuff repair based on the preoperative tear size has not yet been well described.

Purpose/hypothesis: The purpose of this study was to evaluate the recovery period of muscle strength by a serial assessment of isometric strength after arthroscopic rotator cuff repair based on the preoperative tear size. The hypothesis was that muscle strength in patients with small and medium tears would recover faster than that in those with large-to-massive tears.

Use of plate fixation without coracoclavicular ligament augmentation for unstable distal clavicle fractures.

Background: The purpose of this study was to evaluate the clinical and radiologic outcomes of unstable distal clavicle fractures treated with anatomic plate fixation without coracoclavicular ligament augmentation and to compare the outcome of Neer type IIA with that of type IIB.

Methods: Twenty-five patients with unstable distal clavicle fractures who underwent anatomic plate fixation without coracoclavicular ligament augmentation were enrolled prospectively, including 9 patients of Neer type IIA and 16 patients of Neer type IIB. Clinical outcomes were evaluated using Constant and University of California-Los Angeles (UCLA) scores.

The effect of defect orientation and size on glenohumeral instability: a biomechanical analysis.

Purpose: The purpose of this study was to determine the relationship between bony stability and percentage of anterior glenoid bone loss and the effect of bone loss orientation.

Methods: Twelve cadaveric shoulders were studied. Glenoid bone defects were simulated in two different osteotomy angles: 0° and 45° to the superoinferior (SI) axis of the glenoid.

The Correlation of Tunnel Position, Orientation and Tunnel Enlargement in Outside-in Single-Bundle Anterior Cruciate Ligament Reconstruction.

Purpose: Tunnel widening after anterior cruciate ligament (ACL) reconstruction is a frequently described phenomenon. The possible etiology is multi-factorial with some mechanical and biological factors. Among those, we intended to determine the relation between the location and orientation of the femoral tunnel and the femoral tunnel enlargement after outside-in single-bundle ACL reconstruction.
