BACKGROUND: Following anterior cruciate ligament (ACL) reconstruction, the mechanical loading of the tissues has a significant impact on tendon-to-bone healing. The purpose of this study was to determine the effect of the timing of the initiation of mechanical loading on healing of a tendon graft in a bone tunnel. METHODS: ACL reconstruction using a flexor tendon autograft was performed in 56 mice randomized to 4 groups with differing times to initiation of postoperative mechanical loading: (1) immediate, (2) 5 days, (3) 10 days, or (4) 21 days following surgery...

BACKGROUND: Early repair of isolated supraspinatus tears could prevent further deterioration of the rotator cuff; however, there is no consensus on the management of such tears because of a lack of long-term outcome studies. The purposes of this study were to report the 10-year outcomes of isolated supraspinatus repairs and to investigate the factors that favor healing and recovery. METHODS: We retrieved the records of all 511 patients who, in 2003, underwent repair of full-thickness isolated supraspinatus tears, performed by 15 surgeons at 15 centers...

PURPOSE OF THE STUDY Our study aimed to evaluate a group of patients who in the period from 2005 to 2014 underwent a four-corner arthrodesis of the wrist in our department. We also wanted to verify the hypothesis as to whether the use of conventional dorsal plate without the application of bone grafts leads to comparable results as the use of dorsal locking plates and routine application of bone grafts. MATERIAL AND METHODS Throughout the years 2005 to 2014 the four-corner arthrodesis of the wrist was performed in our department in a total of 62 patients, in two cases bilaterally...

We evaluated the surgical outcomes of Haglund's triad using a central tendon-splitting approach, with Achilles tendon partial detachment and debridement, excision of the retrocalcaneal bursa, resection of Haglund's prominence, and reattachment of the Achilles tendon. The medical records of 22 patients (22 heels) who had undergone surgical correction of Haglund's triad from January 2010 to December 2015 were reviewed retrospectively. The visual analog scale pain score, American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scale score, and 36-item Short-Form Health Survey physical and mental component scores were prospectively collected preoperatively, 6 months postoperatively, and at the last visit...

INTRODUCTION: Suboptimal healing of the tendon bone interface (TBI) remains an unsolved problem. One solution is a biocompatible tissue engineered construct that promotes augmented healing. We hypothesisze that 1.) the presence of Platelet Rich Plasma (PRP) and prolonged in vitro incubation produces tissue engineered tendon bone interface scaffolds with greater reseeding of viable Adipo-derived Stem Cells (ADSC) and 2.) when implanted with extracellular matrix hydrogel, constructs will display superior in vivo strength repair and biocompatibility...

BACKGROUND: Platelet-rich plasma (PRP) has been applied as an adjunct to rotator cuff repair to improve tendon-bone healing and potentially reduce the incidence of subsequent tendon retears. PURPOSE: To investigate whether the midterm clinical and radiographic outcomes of arthroscopic supraspinatus repair are enhanced after repeated postoperative applications of PRP. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1. METHODS: A total of 60 patients (30 control; 30 PRP) were initially randomized to receive 2 ultrasound-guided injections of PRP to the tendon repair site at 7 and 14 days after double-row arthroscopic supraspinatus repair or not...

PURPOSE: Platelet-rich plasma containing large amounts of growth factors is purported to increase repaired flexor tendon strength. However, the use of bovine thrombin has the risk of antibody formation. We evaluated the effects of the newer generation autologous platelet-rich fibrin (PRF) on flexor tendon healing. METHODS: We performed surgical repair of 32 flexor tendons from the index and ring digits of the hind paws of 8 New Zealand white rabbits. In the PRF group, the PRF membrane was either wrapped around or interposed between the repair sites...

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: The operative reconstruction of a torn or insufficient anterior cruciate ligament has become a routine surgical procedure in orthopedics. The long-term success of an anterior cruciate ligament reconstruction depends on the ability of the graft to heal adequately in a bone tunnel. Investigators studying reconstructions described healing within a tunnel as osseous ingrowth and incorporation. In particular, helping the healing using autologous material for the best integration process was a new idea that helped us to set up this study...

Electrospinning is a simple and versatile technique that relies on the electrostatic repulsion between surface charges to continuously draw nanofibers from a viscoelastic fluid. It has been applied to successfully produce nanofibers, with diameters down to tens of nanometers, from a rich variety of materials, including polymers, ceramics, small molecules, and their combinations. In addition to solid nanofibers with a smooth surface, electrospinning has also been adapted to generate nanofibers with a number of secondary structures, including those characterized by a porous, hollow, or core-sheath structure...

BACKGROUND: In order to introduce new pharmacological agents with the intent to inhibit the adhesion formation, it is important to test such products on laboratory animals under a protocol that can evaluate the quantitative and qualitative aspects of healing of the tendons. Most experimental models focus on the tensile strength and histological analysis of the tendons, failing to sufficiently quantify the degree of the adhesion formation. METHODS: The experiment included six male New Zealand rabbits that underwent surgery of their right forepaws...

Tendons are dense, fibrous connective tissues which carry out the essential physiological role of transmitting mechanical forces from skeletal muscle to bone. From a clinical perspective, tendinopathy is very common, both within the sporting arena and amongst the sedentary population. Studies have shown that light therapy may stimulate tendon healing, and more recently, intense pulsed light (IPL) has attracted attention as a potential treatment modality for tendinopathy; however, its mechanism of action and effect on the tendon cells (tenocytes) is poorly understood...

PURPOSE: Age-related modifications of tendons, such as reduced tenocyte proliferation and modified extracellular matrix (ECM) turnover, have been previously described, but results are often incomplete and discordant. The aim of this study was to investigate, using morphological and molecular methods, the effect of ageing on human tendons and tenocytes, especially focusing on the collagen turnover pathways, in order to understand how the ageing process could influence tendon biology and structure...

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...

Tendon healing is slow and usually results in inferior fibrotic tissue formation. Recently, application of tendon derived stem cells (TDSCs) improved tendon healing in animal studies. In a chicken model, local injection of antioxidants reduced tendon adhesion after tendon injury. An in vitro study demonstrated that supplementation of H2O2 reduced tenogenic marker expression in TDSCs. These findings suggested that the possibility of TDSCs is involved in tendon healing and the cellular activities of TDSCs might be affected by oxidative stress of the local environment...
