Tendons are susceptible to injury, either due to major overload or repeated sublinical injury. Individual fibres can withstand 2-5% strain before undergoing plastic deformation & permanent elongation. Tendons as a whole can withstand up to 20-50% strain, while still demonstrating a linear response and return to normal length. Under normal usage, tendons are strained only to 25-33% of maximum st...

OBJECTIVE To present the outcomes of posterior cruciate ligament (PCL) double-bundle reconstruction using autologous hamstring tendons, with a minimum follow-up of two years. METHODS Evaluation of 16 cases of PCL injury that underwent double-bundle reconstruction with autogenous hamstring tendons, between 2011 and 2013. The final sample consisted of 16 patients, 15 men and one woman, with a m...

PURPOSE To report the mid-term results of flexor hallucis longus (FHL) tendon transfer for reconstruction of chronically ruptured Achilles tendons. METHODS 24 men and 12 women aged 56 to 78 (mean, 70) years underwent FHL tendon transfer for reconstruction of chronically ruptured Achilles tendons by a single surgeon. Ruptures were secondary to trauma (n=20), long-term steroid intake (n=12), or...

The use of radiofrequency ablation for thermomodulation of connective tissues has gained acceptance with some surgeons. It is now mainly used for shoulder instability, and two techniques are commonly applied - ablation in a uniform pattern (paintbrush) and ablation in a linearly dispersed fashion (grid). The use of these techniques for shrinkage of tendons or cruciate ligaments is not widely ac...

The long-term goal of this research is to identify the dominant mechanisms that control the dynamic tension in submerged cables. This goal addresses the need to suppress or alleviate the dynamic component of cable tension that may adversely affect the performance of underwater cables and any mission they are used to support. For instance, large dynamic tension forces may degrade the positioning...

Introduction: Postoperative finger function after flexor tendon graft is occasionally unsatisfactory. Postoperative adhesion inhibits the restoration of excursion and strength of the grafted tendons. Hyaluronic acid (HA) is not only a lubricant but also a factor to prevent adhesion. The purpose of this study is to evaluate the changes of excursion resistance between potential graft donor source...

background clinical tendon injuries represent serious and unresolved issues of the case on how the injured tendons could be improved based on natural structure and mechanical strength. the aim of this studies the effect of aquatic activities and alogenic platelet rich plasma (prp) injection in healing achilles tendons of rats. methods forty rats were randomly divided into 5 equal groups. sevent...

BACKGROUND de Quervain's disease is a condition in which there is pain in the radial styloid process caused by stenosing tenosynovitis of the abductor pollicis longus (APL) or/and extensor pollicis brevis (EPB) tendons in the first extensor compartment of the wrist. In this study we studied variations in the tendons of the EPB in the first extensor compartment and its site of insertion. METHO...

BACKGROUND Deer tendons are believed more effective than cattle tendons in tonifying kidney yang (shen yang) and enhancing bone and tendons. This study aims to differentiate the two types of tendons by a loop-mediated isothermal amplification (LAMP) test and bone remodeling bioassays. METHODS Internal control primers to detect both types of tendons and specific primers for deer tendons were d...

PURPOSES To assess the tensile strength of the modified 4-strand cruciate technique for obliquely lacerated tendons, and to compare the findings with the strength of transversely lacerated tendons repaired at various grasping depths. METHODS 60 porcine front foot tendons were evenly divided into 4 groups. In groups 1 to 3, tendons were transversely lacerated and repaired with grasping points ...
