Partially mineralized fibrous tissue situated between tendon and bone is believed to be tougher than either tendon or bone, possibly serving as a compliant, energy absorptive, protective barrier between the two. This tissue does not reform following surgical repair (e.g., rotator cuff tendon-to-bone re-attachment) and might be a factor in the poor outcomes following such surgeries. Towards our long-term goal of tissue engineered solutions to functional tendon-to-bone re-attachment, we tested the hypotheses that partially mineralized fibrous matrices can derive toughness from mobility of mineral along their fibers, and that in such cases toughness is maximized at levels of mineralization sufficiently low to allow substantial mobility...

CONTEXT: Surgical cuff repair is indicated in full-thickness rotator cuff tear when non-operative treatment fails. Surgical cuff repair can comprehend surgery of long head of the biceps when concomitant biceps pathology is present. However, the studies executed up to now do not have yet clearly defined if additional biceps surgery affects the shoulder functionality in patients who underwent rotator cuff repair. OBJECTIVE: The aim of this study is to verify if the concomitant biceps surgery prejudices the shoulder functionality during the short-term period in rotator cuff repair patients...

BACKGROUND: Retearing mechanism after transosseous equivalent (TOE) rotator cuff repair has not been fully clarified yet. OBJECTIVE: The purposes of this study were to compare the stress distribution pattern in the tendon stump between knotted and knotless TOE repair and to investigate the role of suture tension applied during medial knot tying using a 3-dimensional finite element (3D-FE) method. METHODS: Both knotted and knotless TOE repairs were simulated on the 3D-FE human rotator cuff tear model...

PURPOSE: The optimum treatment strategy for the surgical management of partial-thickness rotator cuff tears (PTRCT) is evolving. In this study, two research questions were sought to be answered: "Does the repair technique for PTRCTs involving >50% of the tendon thickness have an effect on structural and functional outcomes of arthroscopic repair?" and "Is there a difference in outcomes of arthroscopically treated articular- and bursal-sided PTRCTs?". METHODS: A systematic review according to the PRISMA statement was conducted to identify all literature published reporting on outcomes of arthroscopic treatment of PTRCTs classified with the Ellman classification with minimum 2-year follow-up...

BACKGROUND: Pseudoparalysis remains one of the most challenging conditions in shoulder surgery. Long thought of as an unsolvable problem, recent advances in surgical techniques offer potential return of overhead motion in the setting of massive irreparable rotator cuff tears. This article summarizes the available literature including existing definitions and the results of different treatment approaches regarding range of motion, outcome scores, and reversal. METHODS: In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic review of the MEDLINE database, Cochrane database, Physiotherapy Evidence Database, and Google Scholar database was performed for studies that defined a preoperative shoulder group as having pseudoparalysis...

BACKGROUND: The original approach for the repair of torn rotator cuffs involved an open technique with sutures passing through the greater tuberosity and tendon. The development of suture anchors allowed for an all-arthroscopic approach with anchor configurations attempting to re-create a transosseous fixation pattern. Presently, an arthroscopic approach can be combined with a transosseous suture configuration without using anchors. PURPOSE: To evaluate cyclic loading, ultimate load to failure, and the failure mechanisms of transosseous-equivalent (TOE) repair with anchors and anchorless transosseous (AT) repair of rotator cuff tears...

CONTEXT: Recent advances within the field of genetics are currently changing many of the methodologies in which medicine is practiced. These advances are also beginning to influence the manner in which physical therapy services are rendered. Rotator cuff pathology is one of the most common diagnoses treated by the sports physical therapist. The purpose of this commentary is to educate sports physical therapists on the recent advances regarding how genetics influences rotator cuff pathology, including rotator cuff tears, and provide a perspective on how this information will likely influence post-operative shoulder rehabilitation in the near future...

BACKGROUND: Rotator cuff tears are a common source of pain and disability, and poor healing after repair leads to high retear rates. Bone loss in the humeral head before and after repair has been associated with poor healing. The purpose of the current study was to mitigate bone loss near the repaired cuff and improve healing outcomes. METHODS: Sclerostin antibody (Scl-Ab) treatment, previously shown to increase bone formation and strength in the setting of osteoporosis, was used in the current study to address bone loss and enhance rotator cuff healing in an animal model...

BACKGROUND: Application of fibroblast growth factor 2 (FGF-2) may improve the healing response after rotator cuff (RC) surgical repair. This study aimed to determine whether FGF-2-impregnated gelatin hydrogel sheet (GHS) incorporation into the bony trough on the greater tuberosity facilitates healing after RC surgical repair in rabbits. METHODS: We assigned 120 adult male Japanese white rabbits treated with unilateral surgery for supraspinatus tendon repair into the following groups: suture-only group (suture); suture and GHS with phosphate-buffered saline (carrier); suture and GHS with 3 µg of FGF-2 (F3); and suture and GHS with 30 µg of FGF-2 (F30)...

Rotator cuff injuries are among the most common in orthopaedics, with rotator cuff repair surgery consistently reported as one of the most commonly performed orthopaedic procedures. Patient satisfaction is becoming an increasingly important outcome metric as health care continues to evolve with regard to quality measures affecting physician reimbursement. Evidence supports that postoperative patient satisfaction, an important quality outcome metric, is highly influenced by preoperative patient expectations, which are in turn governed by patient knowledge and understanding...

BACKGROUND: In patients with rotator cuff tears, muscle degeneration is known to be a predictor of irreparable tears and poor outcomes after surgical repair. Fatty infiltration and volume of the whole muscles constituting the rotator cuff were quantitatively assessed using 3-dimensional 2-point Dixon magnetic resonance imaging. METHODS: Ten shoulders with a partial-thickness tear, 10 shoulders with an isolated supraspinatus tear, and 10 shoulders with a massive tear involving supraspinatus and infraspinatus were compared with 10 control shoulders after matching age and sex...

BACKGROUND: Gout commonly involves joint inflammation, and clinical epidemiological studies on involved tendons are scant. Rotator cuff tears are the most common cause of shoulder disability, and surgery is one of the choices often adopted to regain previous function. PURPOSE: To investigate the risk of receiving rotator cuff repair surgery among patients with gout and to analyze possible risk factors to design an effective prevention strategy. STUDY DESIGN: Cohort study; Level of evidence, 3...

BACKGROUND: Addressing preoperative shoulder stiffness before rotator cuff repair (RCR) is advocated, but the effectiveness of this approach is debatable. We hypothesized that 1-stage treatment of concomitant rotator cuff tear (RCT) with shoulder stiffness has comparable results with isolated RCT. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, the databases including MEDLINE, Embase, Cochrane Library, and Scopus were searched using the keywords of "shoulder stiffness" OR "adhesive capsulitis" OR "frozen shoulder" AND "rotator cuff...

Pain control after arthroscopic rotator cuff repair will invariably encompass a multimodal approach which will include, in some form, an anesthetic block. The authors of "Effects of a Single-Dose Interscalene Block on Pain and Stress Biomarkers in Patients Undergoing Arthroscopic Rotator Cuff Repair: A Randomized Controlled Trial" demonstrate better pain control and a decrease in levels of the stress biomarker insulin with the use of a single-dose interscalene block (SISB) and general anesthesia compared to general anesthesia alone...

Large rotator cuff tear size and advanced muscle degeneration can affect reparability of tears and compromise tendon healing. Clinicians often rely on direct measures of rotator cuff tear size and muscle degeneration from magnetic resonance imaging (MRI) to determine whether the rotator cuff tear is repairable. The objective of this study was to identify the relationship between gene expression changes in rotator cuff muscle degeneration to standard data available to clinicians. Radiographic assessment of preoperative rotator cuff tear severity was completed for 25 patients with varying magnitudes of rotator cuff tears...
