BACKGROUND: Recent studies have shown a correlation between scapular geometry and the development of atraumatic rotator cuff tears. However, a paucity of literature is available on the effects of critical shoulder angle (CSA) and acromial index (AI) on functional outcomes after arthroscopic rotator cuff repair. Hypothesis/Purpose: The purpose was to investigate the influence of CSA and AI on 24-month functional outcomes after arthroscopic rotator cuff repair. The hypothesis was that a larger CSA or AI would result in poorer postoperative outcomes...

This Level II study assessed clinically relevant outcomes for repair of large, retracted infraspinatus tendons (ISTs) using a demineralized bone matrix (DBM) sponge (FlexiGraft) hydrated in platelet-rich plasma (PRP) versus direct repair in a validated canine model. Adult research dogs (n = 10) were used. The IST was transected in each shoulder (n = 20) and randomized to direct repair or repair with DBM-PRP interposition at 4 weeks posttransection. At 12 weeks postrepair, dogs were sacrificed, and the repair evaluated by magnetic resonance imaging (MRI), histology, and biomechanical testing...

BACKGROUND: Current evaluation of muscle fatty infiltration has been limited by subjective classifications. Quantitative fat evaluation through magnetic resonance imaging (MRI) may allow for an improved longitudinal evaluation of the effect of surgical repair on the progression of fatty infiltration. HYPOTHESES: We hypothesized that (1) patients with isolated full-thickness supraspinatus tendon tears would have less progression in fatty infiltration compared with patients with full-thickness tears of multiple tendons and (2) patients with eventual failed repair would have higher baseline levels of fatty infiltration...

Surgical repair is a common treatment for rotator cuff tear; however, the retear rate is high. A high degree of suture repair strength is important to ensure rotator cuff integrity for healing. The purpose of this study was to compare the mechanical performance of rotator cuffs repaired with a mesh suture vs traditional polydioxanone suture II and FiberWire sutures in a canine in vitro model. Seventy-two canine shoulders were harvested. An infraspinatus tendon tear was created in each shoulder. Two suture techniques-simple interrupted sutures and 2-row suture bridge-were used to reconnect the infraspinatus tendon to the greater tuberosity, using 3 different suture types: mesh suture, polydioxanone suture II, or FiberWire...

BACKGROUND: Treatment choices for total shoulder arthroplasty (TSA) in the absence of full-thickness rotator cuff tears (RCTs) are not clearly defined in current literature. This study investigated the prevalence and effect of preoperative partial-thickness RCTs and muscular degenerative changes on postoperative outcomes after TSA. METHODS: Medical records and magnetic resonance imaging studies were reviewed for patients who underwent TSA for primary glenohumeral osteoarthritis with minimum 2-year follow-up to determine preoperative tear classification, Goutallier grade, and supraspinatus tangent sign...

Rotator cuff tear is a common disease affecting patients after stroke. It's a cause of pain and dysfunction that may compromise normal stroke rehabilitation. For many cases there is still controversy between whether to use surgical or conservative intervention. Treatment for cuff tears range from physical therapy to surgery. This paper describes for the first time the effect of Fascial Manipulation(®) (FM(®)) on rotator cuff tear in a post stroke patient. A 69 year old female stroke patient with full absence of distal components of the tendons of the rotator cuff, functional limitations on active movement of shoulder flexion and abduction of the left arm and perceived pain scored 10/10 on the Visual Analogic Scale, was assessed and treat with one session of FM(®) A basic theory that explains the healing results of FM(®) is that mechanoreceptors, such as spindle cells and other receptors, are located in the deep fascia and activated when movement are performed...

Superior capsular reconstruction (SCR) is a novel technique for treating irreparable rotator cuff tears in younger patients in whom a reverse total shoulder arthroplasty is not the optimal treatment choice. This case study describes a middle-aged male with a recurrent, massive, irreparable rotator cuff tear treated with SCR that subsequently failed at the glenoid attachment. The patient underwent successful arthroscopic revision of the SCR. The case illustrates the MRI and arthroscopic correlations of the failed dermal allograft reconstruction, which to our knowledge has not been previously shown in the radiology literature...

BACKGROUND: In 2013 Moor et al introduced the concept of the critical shoulder angle (CSA) and suggested that an abnormal CSA was a leading factor in development of rotator cuff tear (RCT) and osteoarthritis (OA) of the shoulder. This study assessed whether the CSA was associated with RCT and OA and tested the inter- and intrarater reliability of the CSA when measuring RCT and OA. MATERIALS AND METHODS: The study was performed as a retrospective case-control study...

BACKGROUND: Arthroscopic rotator cuff repair (ARCR) can be associated with significant postoperative pain. Concern for opioid abuse has led surgeons to identify alternative, efficacious methods of postoperative analgesia. To determine whether transcutaneous electrical nerve stimulation (TENS) can have a similarly beneficial effect after shoulder procedures, we conducted a prospective double-blinded randomized trial in patients undergoing outpatient ARCR. METHODS: All patients undergoing ARCR of a full-thickness rotator cuff tear by the senior authors were identified...

BACKGROUND: Hyperlipidemia (HL) has been identified as a risk factor for rotator cuff tear, but no studies have evaluated its effects on healing. The purpose of this study was to evaluate the effect of HL and statin use on rotator cuff healing after arthroscopic repair. METHODS: This was a retrospective review of 85 patients (86 shoulders) who underwent arthroscopic rotator cuff repair with postoperative ultrasound evaluation. Ultrasound findings were graded no retear, partial-thickness retear (PT), or full-thickness retear (FT)...

BACKGROUND: Higher critical shoulder angle (CSA) is correlated with rotator cuff tears (RCTs), whereas lower CSA is associated with glenohumeral osteoarthritis (OA). Our goal was to investigate whether patients with concurrent glenohumeral OA and full-thickness RCTs demonstrate a higher CSA than patients with OA alone. METHODS: Using a 2-surgeon shoulder arthroplasty registry, we identified 31 patients with glenohumeral OA and full-thickness RCTs confirmed by plain radiography and magnetic resonance imaging, respectively...
