Atrophy patterns in isolated subscapularis lesions.

Background: While supraspinatus atrophy can be described according to the system of Zanetti or Thomazeau there is still a lack of characterization of isolated subscapularis muscle atrophy. The aim of this study was to describe patterns of muscle atrophy following repair of isolated subscapularis (SSC) tendon.

Methods: Forty-nine control shoulder MRI scans, without rotator cuff pathology, atrophy or fatty infiltration, were prospectively evaluated and subscapularis diameters as well as cross sectional areas (complete and upper half) were assessed in a standardized oblique sagittal plane.

Single versus double row suture anchor fixation for greater tuberosity fractures - a biomechanical study.

Background: Fractures of the humeral greater tuberosity (GT) are a frequent injury progressively treated with arthroscopic suture anchor repair. Yet, no biomechanical study has been performed comparing fixation strength of arthroscopic single- (SR) vs. double row (DR) fixation.

Patients' expectations of shoulder instability repair.

Purpose: To analyze and compare patient expectations of primary and revision shoulder stabilization and to assess the factors associated with patients' expectations.

Methods: Pre-operative patient expectations after shoulder instability repair were prospectively assessed using a self-designed questionnaire. The survey included questions on the expected level and type of return to sports, instability, pain, risk of osteoarthritis, and overall shoulder condition.

Long-term Results After Arthroscopic Repair of Isolated Subscapularis Tears.

Background: Although some reports have presented short- to midterm results after arthroscopic repair of isolated subscapularis (SSC) tendon tears, long-term evaluation is still lacking.

Hypothesis: Long-term results after arthroscopic repair of isolated SSC tears are comparable with the functional and radiological short- to midterm outcomes described in the literature.

Study Design: Case series, Level of evidence, 4.

Results of Arthroscopic Bankart Repair for Anterior-Inferior Shoulder Instability at 13-Year Follow-up.

Background: Anterior-inferior shoulder instability is a common injury in young patients, particularly those practicing overhead-throwing sports. Long-term results after open procedures are well studied and evaluated. However, the long-term results after arthroscopic repair and risk factors of recurrence require further assessment.
