BACKGROUND: Numerous biomechanical studies have addressed normal shoulder function and the factors that affect it. While these investigations include a mix of in-vivo clinical reports, ex-vivo cadaveric studies, and computer-based simulations, each has its own strengths and limitations. A robust methodology is essential in cadaveric work but does not always come easily. Precise quantitative measurements are difficult in in-vivo studies, and simulation studies require validation steps...

Although the exact function of the subacromial bursa as it relates to rotator cuff repair is still debatable, most surgeons would agree that the more invasive the procedure, the more likely there will be scarring and/or adhesions, which can lead to decreased motion. So, when performing subacromial bursectomy during rotator cuff repair, "Observe due measure, moderation is best in all things [subacromial]."

Delamination of rotator cuff tears presents a challenge to shoulder arthroscopists. Tear pattern recognition and an understanding of anatomy as it relates to the superior capsule guide treatment strategies. The key to management of a delaminated rotator cuff tear is to recognize differential retraction of respective layers. Successful outcomes of surgical management require conscientious and deliberate restoration of the attachment points of the cable. The goal is to produce an anatomic repair.

BACKGROUND AND OBJECTIVE: Calcific tendinitis is commonly found in the rotator cuff; however, it is very rare in the long biceps tendon (LBT). Furthermore, calcific tendinitis involving the LBT in the hemiplegic shoulder after a stroke has not been previously reported. MATERIALS AND METHOD: We present a case of a 63-year-old man who suffers from a stroke and atypical calcific tendinitis involving the LBT as a rare cause of hemiplegic shoulder pain. The patient had experienced intractable pain in the right hemiplegic shoulder for more than 6 months with a waxing and waning course...

Background: Painful dysfunctional shoulders with irreparable rotator cuff tears (IRCTs) in active patients are a challenge. Arthroscopic superior capsular reconstruction (ASCR) is a new treatment option originally described using a fascia lata autograft harvested through an open approach. However, concerns about donor site morbidity have discouraged surgeons from using this type of graft. Hypothesis: ASCR using a minimally invasive harvested fascia lata autograft produces good 6-month and 2-year shoulder outcomes in IRCTs, with low-impact thigh morbidity at 2 years...

BACKGROUND: Recent orthopedic research has questioned the effect of opioid use on surgical outcomes. This study investigated this in the context of arthroscopic rotator cuff repair. We hypothesized that preoperative opioid use would be associated with inferior outcomes and greater postoperative opioid requirements. METHODS: A database query identified adult patients with full-thickness or partial-thickness supraspinatus tears surgically treated between 2011 and 2015...

HYPOTHESIS: We hypothesized that a new method considering the humeral head would distinguish rotator cuff tears (RCTs) and osteoarthritis (OA) better than the critical shoulder angle (CSA). METHODS: A total of 1011 patients were tested in this study and divided into 4 groups: those with RCTs (n = 493), those with OA (n = 73), those with anterior instability (n = 361), and those with adhesive capsulitis (n = 84). The CSA and new radiologic parameters including the humeral head were measured in the true anterior-to-posterior view: the Y angle connecting the lower end of the glenoid (LG), the center of the humeral head (CH), and the upper end of the glenoid (UG); the G angle connecting UG, CH, and the lateral tip of the acromion; the YG angle connecting LG, CH, and the lateral tip of the acromion; and the R angle connecting UG, LG, and CH...

STUDY DESIGN: Single-blind, randomized controlled trial. BACKGROUND: Treatments for rotator cuff (RC) tendinopathy include RC muscle strengthening to promote better muscle recruitment in order to minimize subacromial narrowing during active movement. Glenohumeral adductors recruitment has also been shown to prevent such narrowing in asymptomatic individuals; therefore, adding glenohumeral adductor coactivation during RC strengthening could enhance the efficacy of RC strengthening...

AIMS: In patients with a rotator cuff tear, tear pattern and tendon involvement are known risk factors for the development of pseudoparalysis of the shoulder. It remains unclear, however, why similar tears often have very different functional consequences. The present study hypothesizes that individual shoulder anatomy, specifically the moment arms (MAs) of the rotator cuff (RC) and the deltoid muscle, as well as their relative recruitment during shoulder abduction, plays a central role in pseudoparalysis...

The shoulder joint is functionally and structurally complex and is composed of bone, hyaline cartilage, labrum, ligaments, capsule, tendons and muscles. It links the trunk to the upper limb and plays an important biomechanical role in daily activities. Indications for imaging of the shoulder have considerably increased in the last few years. The article focuses mainly on Magnetic Resonance Imaging (MRI) as well as MR and CT arthrography, diagnostic procedures of choice for assessment of internal derangement of the shoulder...

BACKGROUND: Platelet rich plasma (PRP) is widely used in rotator cuff repairs but its effect on the healing process is unclear. Several cell culture studies on the effect of allogenic PRP have reported promising results but are not transferable to clinical practice. The aim of the present study is to assess the possible effect of autologous PRP on rotator cuff tendon cells. The amount of growth factors involved with tendon-bone healing (PDGF-AB, IGF-1, TGF-β1, BMP-7 and -12) is quantified...

CASE: An active elderly patient with bilateral chronic rotator cuff tear underwent a reverse total shoulder arthroplasty (RTSA) on the right shoulder and an arthroscopic superior capsular reconstruction (ASCR) with a fascia lata autograft on the left shoulder. To our knowledge, this is the first reported case that compares these 2 techniques for irreparable rotator cuff tears in the same patient. CONCLUSION: The patient had very good midterm (2 and 8 years of follow-up) functional outcomes with both treatment options...

Despite advancements in surgical techniques and materials for rotator cuff repair procedures, primary repair failures remain common. This study examines the use of electrochemically aligned collagen (ELAC) threads woven into biotextile scaffolds as grafts to repair critical infraspinatus tendon defects in New Zealand White rabbits. Three surgical treatment groups were evaluated: rabbits undergoing direct repair as operative controls, rabbits receiving ELAC scaffolds alone, and rabbits treated with mesenchymal stem cell (MSC)-seeded ELAC scaffolds...

BACKGROUND: The Patient-Reported Outcomes Measurement Information System (PROMIS) Global-10 was recently developed to assess physical and mental health and provide an estimated EuroQol-5 Dimension (EQ-5D) score. This instrument needs to be validated for specific patient cohorts such as those with rotator cuff pathology. HYPOTHESIS: There is moderate to high correlation between the PROMIS Global-10 and legacy patient-reported outcome measures; PROMIS Global-10 will not show ceiling effects; and estimated EQ-5D scores will show good correlation and low variance with actual EQ-5D scores...

Partial articular-sided supraspinatus tendon avulsion (PASTA) tears are a common clinical problem that can require surgical intervention to reduce patient symptoms. Currently, no consensus has been reached regarding the optimal repair technique. The PASTA Bridge technique was developed by the senior author to address these types of lesions. A controlled laboratory study was performed comparing the PASTA Bridge with a standard transtendon rotator cuff repair to confirm its biomechanical efficacy. A 50% articular-sided partial tear of the supraspinatus tendon was created on 6 matched pairs of fresh-frozen cadaveric shoulders...
