BACKGROUND: The established surgical technique for lesion of the anterior cruciate ligament (ACL) is reconstruction with an autologous tendon. However, patients after ACL-replacement have increased osteoarthritis rates. Possible explanations are persistent knee instability and the loss of the ACL's proprioceptive function. Therefore, surgeons have developed an alternative treatment to preserve the ACL by readapting femoral ACL lesions by temporary protective dynamic intraligamentary stabilisation (DIS)...

PURPOSE: Floating knee injuries are relatively uncommon injuries. We report the prevalence, location, and severity of heterotopic ossification (HO) around the knee in patients treated with antegrade tibial intramedullary nailing and ipsilateral antegrade versus retrograde femoral intramedullary nailing as well as how the severity of HO around the knee affects knee range of motion (ROM). METHODS: From 2004 to 2014, 26 floating knee injuries were included. Radiographs were reviewed to determine presence, location, and severity of HO...

CONTEXT: Recent epidemiology studies indicated a steady increase of anterior cruciate ligament (ACL) injury in young athletes. ACL reconstruction (ACLR) is currently a standard of the care, but effect of ACLR graft including bone patellar tendon bone (BTB), hamstring tendon (HT), or iliotibial band (ITB) on balance and hop performance is understudied. OBJECTIVE: To compare balance and hop deficits between uninvolved and reconstructed limbs in each autograft type (aim 1) and among the three autograft groups (aim 2)...

Accidental self-inflicted knife injuries to digits are a common cause of tendon and nerve injury requiring hand surgery. There has been an apparent increase in avocado related hand injuries. Classically, the patients hold the avocado in their non-dominant hand while using a knife to cut/peel the fruit with their dominant hand. The mechanism of injury is usually a stabbing injury to the non-dominant hand as the knife slips past the stone, through the soft avocado fruit. Despite their apparent increased incidence, we could not find any cases in the literature which describe the "avocado hand"...

Due to the exposure of the hands in the daily routine, defect wounds of the hand are common. The injury severity varies and ranges from small fingertip defects to large soft tissue lesions with exposed tendons, nerves and vessels. The complete extent of the soft tissue defect is often only recognizable after meticulous debridement. A considerable variety of techniques for defect coverage are available to the surgeon but the actual challenge is to select the most appropriate procedure which will result in the smallest possible residual defect...

This is the first report of extensive bilateral patellar tendon ossification occurring over a prolonged time after a unilateral knee injury. An 84-year-old Japanese man with a spinal cord injury caused by a burst fracture of the T12 vertebra presented with a bony hard prominence on the left knee, which was injured in a traffic accident when he was 77 years old. Radiography revealed extensive ossification of the bilateral patellar tendons. We review the English literature with a focus on the localization of bilateral heterotopic ossification of the knee in patients who had a central nervous system injury...

BACKGROUND: Trigger finger is a common clinical disorder, characterised by pain and catching as the patient flexes and extends digits because of disproportion between the diameter of flexor tendons and the A1 pulley. The treatment approach may include non-surgical or surgical treatments. Currently there is no consensus about the best surgical treatment approach (open, percutaneous or endoscopic approaches). OBJECTIVES: To evaluate the effectiveness and safety of different methods of surgical treatment for trigger finger (open, percutaneous or endoscopic approaches) in adults at any stage of the disease...

INTRODUCTION: Chronic lateral ankle instability occurs in up to 20% of ankle injuries. Most can be treated conservatively, but surgical reconstruction is required if conservative treatment fails. Modified Broström-Gould procedure is an effective surgical treatment and the augmentation of this procedure with a periosteal flap may confer additional stability. We report on the outcome of a technique combining a modified Broström-Gould procedure augmented with a periosteal flap in patients with chronic lateral ankle instability...

Agenesis, functional deficiency and the common type of the flexor digitorum superficialis of the little finger are reported in the literature to be highly variable with significant discrepancy between clinical and cadaveric frequencies. The aim of this systematic review was to generate overall clinical and cadaveric weighted frequencies, along with ancestry-based, side-based, sex-based and laterality-based frequencies. A systematic literature search identified 34 studies including 12,213 forearms/hands that met the inclusion criteria...

BACKGROUND: Achilles tendon insertional sleeve avulsions occur when the Achilles distal tendon sleeve ruptures off of its insertion into the calcaneal tuberosity, sometimes with a small bony fragment from calcific tendinosis. Little evidence exists describing the outcomes and rerupture rate after operative management of Achilles tendon sleeve avulsions. METHODS: A retrospective chart review was performed to identify patients who sustained an Achilles sleeve avulsion injury treated with operative repair between October 2005 and July 2014...

BACKGROUND: Open Achilles tendon surgery with the patient in the supine position potentially avoids the complications of the prone position, but the safety and viability of the supine position for this procedure are not known. The aim of this study was to test the hypothesis that supine positioning for open repair of acute Achilles tendon ruptures would be safe, with low wound and neurologic complication rates. METHODS: Supine position safety in acute Achilles tendon repair was investigated...

Rene B Svensson, Stuart T Smith, Patrick J Moyer, S Peter Magnusson
Connective tissues are ubiquitous throughout the body and consequently affect the function of many organs. In load bearing connective tissues like tendon, the mechanical functionality is provided almost exclusively by collagen fibrils that in turn are stabilized by covalent cross-links. Functionally distinct tendons display different cross-link patterns, which also change with maturation, but these differences have not been studied in detail at the fibril level. In the present study, a custom built nanomechanical test platform was designed and fabricated to measure tensile mechanics of individual fibrils from rat tendons...

Brianne K Connizzo, Alan J Grodzinsky
Tendinopathy is a significant clinical problem thought to be associated with altered mechanical loading. Explant culture models allow researchers to alter mechanical loading in a controlled in vitro environment while maintaining tenocytes in their native matrix. However, current models do not accurately represent commonly injured tendons, ignoring contributions of associated musculature and bone, as well as regional collagen structure. This study details the characterization of a mouse rotator cuff explant culture model, including bone, tendon, and muscle (BTM)...

Healthy tendons are maintained in homeostasis through controlled usage of glucose for energy and redox equilibrium. Tendon cell stress imposed by overuse injury or vascular insufficiency is accompanied by activation of wound healing pathways which facilitate an adaptive response and the restoration of homeostasis. To understand this response at the gene expression level we have studied the in vivo effects of injected TGF-β1 in a murine model of tendinopathy, as well as treatment of murine tendon explants with either TGF-β1 or hypoxia in vitro...
