INTRODUCTION: The aim of the study was to investigate to what extent the semitendinosus and gracilis tendons had regenerated a minimum of six years after harvest for anterior cruciate ligament (ACL) reconstruction. The place of insertion and the area of the regenerated tendons were compared with the normal contra lateral side. To evaluate the function of the regenerated tendons, the strength in...

Nonenzymatic glycation of connective tissue matrix proteins is a major contributor to the pathology of diabetes and aging. Previously the author and colleagues have shown that nonenzymatic glycation significantly enhances the matrix stability in the Achilles tendon (Reddy et al., 2002, Arch. Biochem. Biophys., 399, 174-180). The present study was designed to gain further insight into glycation-...

OBJECTIVES The effects of disease progression and common tendinopathy treatments on the tissue characteristics of human rotator cuff tendons have not previously been evaluated in detail owing to a lack of suitable sampling techniques. This study evaluated the structural characteristics of torn human supraspinatus tendons across the full disease spectrum, and the short-term effects of subacromia...

UNLABELLED The purpose of the present study was to investigate exercise-related changes in oxygenation in rat skeletal muscles and tendons noninvasively with PET/CT and the hypoxia-selective tracer (64)Cu-diacetyl bis(N(4)-methylthiosemicarbazone) (ATSM) and to quantitatively study concomitant changes in gene expression of 2 hypoxia-related genes, hypoxia-inducible factor 1alpha (HIF1alpha) and...

OBJECTIVE Tendon injuries produce considerable morbidity, long-lasting disability, and remain a considerable challenge for clinicians and patients. The objective of the study was to assess the effect of amnion-derived multipotent progenitor (AMP) cells and amnion-derived cell cytokine solution on Achilles tendon healing by using a rat model. METHODS Achilles tendons of Sprague-Dawley rats wer...

Aging changes mechanical properties of tendons, influencing the transmission strength, postural stability, and risk falling. Tendon stiffness can be modified by exercise intervention. Thus, this systematic review aimed to analyze effects different training programs on triceps sural quadriceps patellar tendons in older adults.

Studies of animal tendons have not yielded clear conclusions about how graft configuration affects stiffness and strength. A recent study of sheep tendons [1] showed that two different braiding techniques reduced failure load by 47% and 57%, respectively, from the parallel strand configuration. Braiding reduced stiffness by 82% and 85%. In a study of calves’ tendons [2], braiding and twisting d...

A 12-year-old hunter gelding became severely lame as a result of a laceration to the sheath of the digital flexor tendons of its left hindlimb, but there was no apparent damage to the tendons. The injury became chronically infected with Pseudomonas and Streptococcus species and Escherichia coli which did not respond to antibiotic treatment, and the horse remained lame. A postmortem examination ...

muscles. These flexor muscles move the fingers through cordlike extensions called tendons, which connect the muscles to bone. The flexor muscles start at the elbow and forearm regions, turn into tendons just past the middle of the forearm, and attach to the bones of the fingers (see Figure 1). In the finger, the tendons pass through tunnels that keep them close to the bones, which helps them wo...

The use of volar locking compression plates for the treatment of fractures of the distal radius is becoming increasingly popular because of the stable biomechanical construct, less soft-tissue disturbance and early mobilisation of the wrist. A few studies have reported complications such as rupture of flexor tendons. We describe three cases of rupture of extensor tendons after the use of volar ...
