Wolfram Thomas, Tom Sascha Thomas, Luca Tafuro, Sebastian Walter
The purpose of this study is to present a "smart," open, minimally invasive surgical technique for rotator cuff repair of the shoulder. On the basis of an anatomic study by Tichy, we use a coracoacromial mobile window: We split-not detach-the deltoid muscle by respecting its fibers' orientation and resect the coracoacromial ligament before repairing the torn rotator cuff tendons with anchors. The described approach is fast, is technically uncomplicated, and can be carried out with a standard set of instruments...

Recent advances to improve outcomes in rotator cuff repair include using arthroscopic double-row suture-bridge techniques in an effort to reconstruct the rotator cuff footprint and improve fixation. However, when using this technique for larger tears, it can be difficult to get the lateral portion of the rotator cuff into an anatomic position. This report describes a triple-row modification of the suture-bridge technique that results in significantly more footprint contact area and contact pressure compared with the double-row and standard suture-bridge techniques...

PURPOSES: There is a lack of substantial clinical evidence endorsing the clinical outcomes of osteotomy for peroneal tendon dislocations. The aim of this study was to compare the post-operative reoperation rates following osteotomy techniques and soft tissues procedures using large database in order to investigate the efficacy of bony techniques. METHODS: Patients who underwent osteotomy and soft tissue procedures for peroneal tendon dislocations were identified and subsequently analysed using the United Healthcare Orthopedic and the Medicare datasets (PearlDiver Patient Record Database, PearlDiver Technologies Inc...

OBJECTIVES: To investigate outcomes after surgical repair of distal biceps tendon rupture and the influence of arm dominance on isokinetic flexion and supination results. BACKGROUND/PURPOSE: While relatively uncommon, rupture of the distal biceps tendon can result in significant strength deficits, for which surgical repair is recommended. The purpose of this study was to assess patient reported functional outcomes and muscle performance following surgery. METHODS: A sample of 23 participants (22 males, 1 female), who had previously undergone surgical repair of the distal biceps tendon, were re-examined at a minimum of one year after surgery...

BACKGROUND: Repair of distal biceps tendon ruptures has become widely accepted. Unfortunately, care of retracted-degenerated injuries remains a challenge for orthopedic surgeons. Complication rates appear to increase when surgery is performed in chronic cases compared to those operated acutely. Multiple techniques for chronic reconstruction with the use of grafts have been described. Recently Morrey, from the Mayo Clinic, proposed a direct anatomic repair of retracted distal biceps tendon ruptures in extreme flexion (60°-90°) to avoid grafting...

Massive rotator cuff tears are difficult to treat surgically due to retraction, degeneration and fraying of the ends of torn tendons, severe fatty infiltration and atrophy of the respective muscles. Procedures developed to close the gap between the rotator cuff and the greater tuberosity of the humerus, such as soft tissue release may be inadequate for large tears. Human or porcine dermal allografts still have uncertain benefits, and tendon transfers seem to be associated with poor outcomes, donor site morbidity and altered mechanics...

BACKGROUND: Quadriceps tendon (QT) ruptures are uncommon and mostly occur in those who are 50-60 years of age. Timely surgical repair can result in a good functional outcome, however, little is known about the outcome in the older patient. METHODS: A retrospective review of all QT ruptures between 2009 and 2014 was conducted. Patients over the age of 80 were included. Those with penetrating trauma or partial ruptures were excluded. A chart review was undertaken to gather demographic and operative details...

BACKGROUND: The study of new genetic biomarkers in genes related to connective tissue repair and regeneration may help to identify individuals with greater predisposition to injury, who may benefit from targeted preventive measures, and those who require longer recovery time following a muscle, ligament or tendon injury. The present study investigated whether single nucleotide polymorphisms of the Elastin gene could be related to MCL injury. METHODS: 60 top class football players were studied to identify single nucleotide polymorphisms for the Elastin (ELN) gene using Allelic Discrimination analysis...

Acute rupture of the Achilles tendon is common and seen most frequently in people who participate in recreational athletics into their thirties and forties. Although goals of treatment have not changed in the past 15 years, recent studies of nonsurgical management, specifically functional bracing with early range of motion, demonstrate rerupture rates similar to those of tendon repair and result in fewer wound and soft-tissue complications. Satisfactory outcomes may be obtained with nonsurgical or surgical treatment...

Rupture of the proximal tendon enthesis of the hamstring muscle (ICM) accounts for approximately 10% of all injuries of the ICM. It occurs most commonly in athletes and active middle-aged individuals. The complete rupture of all three tendons in active patients is generally seen as an indication for surgical repair of the tendon enthesis; however, the correct diagnosis is often not reached in a timely manner. This can lead to prolonged symptoms with pain, weakness and neuralgia. Operative treatment consists of anchor repair of the tendons resulting in good clinical outcome in several case series...

BACKGROUND: Bone marrow aspirate has been used in recent years to augment tendon-to-bone healing, including in rotator cuff repair. However, the healing mechanism in cell-based therapy has not been elucidated in detail. METHODS: Sixteen athymic nude rats were randomly allocated to 2 groups: experimental (human mesenchymal stem cells in fibrin glue carrier) and control (fibrin glue only). Animals were sacrificed at 2 and 4 weeks. Immunohistochemical staining was performed to evaluate Indian hedgehog (Ihh) signaling and SOX9 signaling in the healing enthesis...

REVIEW
Jared R Thomas, Jeffrey Nathan Lawton
Although rare, biceps and triceps tendon ruptures constitute significant injuries that can lead to profound disability if left untreated, especially in the athletic population. Biceps rupture is more common than triceps rupture, with both resulting from a forceful eccentric load. Surgical repair is the treatment method of choice for tendinous ruptures in athletes. Nonoperative management is rarely indicated in this population and is typically reserved for individuals with partial ruptures that quickly regain strength and function...

A three-dimensional (3D) scaffold fabricated via electrohydrodynamic jet printing (E-jetting) and thermally uniaxial stretching, has been developed for tendon tissue regeneration in our previous study. In this study, more in-depth biological test showed that the aligned cell morphology guided by the anisotropic geometries of the 3D tendon scaffolds, leading to up-regulated tendious gene expression including collagen type I, decorin, tenascin-C and biglycan, as compared to the electrospun scaffolds. Given the importance of geometric cues to the biological function of the scaffolds, the degradation behaviors of the 3D scaffolds were investigated...

Flexor tendon rupture is an unusual complication following collagenase injection to relieve contractures. These patients require a close follow-up and in the event of tendon rupture, a decision has to be made whether to repair the tendon or manage the complication conservatively. The authors report the utility of MRI in the prognostication and management of a patient with Dupuytren's contracture, who underwent collagenase injection and subsequently developed flexor digitorum profundus tendon rupture.

: Background Despite the low incidence of deep vein thrombosis (DVT) in foot and ankle surgery, some authors report a high incidence of symptomatic DVT following Achilles tendon rupture. The purpose of this study was to identify DVT risk factors inherent to Achilles tendon repair to determine which patients may benefit from prophylaxis. Methods One hundred and thirteen patient charts were reviewed following elective and nonelective Achilles tendon repair. For elective repair of insertional or noninsertional Achilles tendinopathy, parameters examined included lateral versus prone positioning and the presence versus absence of a flexor hallucis longus transfer...

OBJECTIVES: This study aimed to evaluate the histological and mechanical features of tendon healing in a rabbit model with second-harmonic-generation (SHG) imaging and tensile testing. MATERIALS AND METHODS: A total of eight male Japanese white rabbits were used for this study. The flexor digitorum tendons in their right leg were sharply transected, and then were repaired by intratendinous stitching. At four weeks post-operatively, the rabbits were killed and the flexor digitorum tendons in both right and left legs were excised and used as specimens for tendon healing (n = 8) and control (n = 8), respectively...
