Correlation of Acromial Morphology With Risk and Direction of Shoulder Instability: An MRI Study.

Background: The influence of bony morphology on the development of posterior shoulder instability is not well known.

Purpose: To determine if acromial morphology, as measured on magnetic resonance imaging (MRI), is associated with posterior or anterior shoulder instability.

Design: Cross-sectional study; Level of evidence, 3.

Knotless All-Suture, Soft Anchor Bankart Repair Results in Excellent Patient-Reported Outcomes, High Patient Satisfaction, and Acceptable Recurrent Instability Rates at Minimum 2-Year Follow-Up.

Purpose: To evaluate minimum 2-year outcomes after arthroscopic knotless all-suture soft anchor Bankart repair in patients with anterior shoulder instability.

Methods: This was a retrospective case series of patients who underwent Bankart repair using soft, all-suture, knotless anchors (FiberTak anchors) from 10/2017 to 06/2019. Exclusion criteria were concomitant bony Bankart lesion, shoulder pathology other than that involving the superior labrum or long head biceps tendon, or previous shoulder surgery.

Open Fixation of Displaced Greater Tuberosity Fractures Yields Similar Patient-Reported Outcomes to Acute Arthroscopic Rotator Cuff Repair at 2 Years: A Matched Cohort Analysis.

Purpose: To evaluate and compare patient-reported outcomes (PROs) after isolated greater tuberosity (GT) fracture fixation versus acute rotator cuff repair (RCR) at a minimum of 2 years.

Methods: Patients who underwent isolated GT fracture fixation were compared in a 1-to-3 fashion with patients who underwent arthroscopic RCR for an acute rotator cuff tear by a single surgeon from January 2006 and to July 2018. Data were prospectively collected and retrospectively reviewed.

Minimum 2-Year Clinical Outcomes of Medial Meniscus Root Tears in Relation to Coronal Alignment.

Background: The effect of coronal plane alignment on the outcomes of repairs of the medial meniscus root remains unclear.

Hypothesis: Increased preoperative varus alignment is associated with higher failure rates and lower patient-reported outcomes (PROs) after isolated repair of the medial meniscus root.

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

Arthroscopic Axillary Nerve Neurolysis From the Anteroinferior Glenoid Through the Quadrilateral Space to the Terminal Deltoid Branches.

Axillary nerve compression is a rare cause of posterolateral shoulder pain. Once the diagnosis is confirmed and after failure of conservative measures, open procedures have been the mainstay of treatment for several decades. More recently, arthroscopic techniques have been proposed, which offer several advantages, including improved access to difficult locations, better visualization, and less surgical morbidity.

Mid-Term Outcomes of Arthroscopically-Assisted Anatomic Coracoclavicular Ligament Reconstruction Using Tendon Allograft for High-Grade Acromioclavicular Joint Dislocations.

Purpose: The purposes of this study were to assess clinical and radiographic outcomes of arthroscopically-assisted, anatomic coracoclavicular ligament reconstruction using tendon allograft (AA-ACCR) for the treatment of Rockwood type III-V injuries at minimum 2-year follow-up and to perform subgroup analyses of clinical and radiographic outcomes for acute versus chronic and type III versus type IV-V injuries.

Methods: In this retrospective study of prospectively collected data, patients who underwent primary AA-ACCR for the treatment of type III-V dislocations and had minimum 2-year follow-up were included. Preoperative and postoperative patient-reported outcome scores (PROs) were collected, including American Shoulder and Elbow Surgeons score, Single Numeric Assessment Evaluation score, Short Form-12 Physical Component Summary, Quick Disabilities of the Arm Shoulder and Hand score, and patient satisfaction.

Total Shoulder Arthroplasty After Previous Arthroscopic Surgery for Glenohumeral Osteoarthritis: A Case-Control Matched Cohort Study.

Background: When comprehensive arthroscopic management (CAM) for glenohumeral osteoarthritis fails, total shoulder arthroplasty (TSA) may be needed, and it remains unknown whether previous CAM adversely affects outcomes after subsequent TSA.

Purpose: To compare the outcomes of patients with glenohumeral osteoarthritis who underwent TSA as a primary procedure with those who underwent TSA after CAM (CAM-TSA).

Study Design: Cohort study; Level of evidence, 3.

Primary reverse shoulder replacement with a short stem: A systematic literature review.

Background: Total shoulder arthroplasty implant designs have continued to evolve over the years. One recent change has been the shortening of the humeral component to preserve bone stock and to facilitate revision surgery. Despite promising clinical results, radiographic bone adaptions occur frequently in short-stem total shoulder arthroplasty, and limited data exist on short-stem reverse shoulder arthroplasty (RSA).

Clinical Outcomes of Arthroscopic Suprascapular Nerve Decompression for Suprascapular Neuropathy.

Purpose: To report clinical outcomes following arthroscopic suprascapular nerve (SSN) decompression for suprascapular neuropathy at the suprascapular and/or spinoglenoid notch in the absence of major concomitant pathology.

Methods: We retrospectively reviewed prospectively collected data of 19 patients who underwent SSN release at the suprascapular and/or spinoglenoid notch between April 2006 and August 2017 with ≥2 years of follow-up. Patients who underwent concomitant rotator cuff or labral repairs or had severe osteoarthritis were excluded.
