This study was undertaken to elucidate the mechanism of biological repair at the tendon-bone junction in a rat model. The stump of the toe flexor tendon was sutured to a drilled hole in the tibia (tendon suture group, n = 23) to investigate healing of the tendon-bone junction both radiologically and histologically. Radiological and histological findings were compared with those observed in a sh...

In this study, we innervated bio-inspired proprioception into a soft hand, facilitating robust perception of textures and object shapes. The tendon-driven finger with three joints, inspired by the human finger, was detailed. With tension sensors embedded in tendon that simulate Golgi organ body, 17 types can be identified under uncertain rotation angles actuator displacements. Four classifiers ...

The underlying mechanisms for the viscoelastic behavior of tendon and ligament tissue are poorly understood. It has been suggested that both a flow-dependent and flow-independent mechanism may contribute at different structural levels. We hypothesized that the stress relaxation response of a single tendon fascicle is consistent with the flow-dependent mechanism described by the biphasic theory ...

During rapid movements, tendons can act like springs, temporarily storing work done by muscles and then releasing it to power body movements. For some activities, such as frog jumping, energy is released from tendon much more rapidly than it is stored, thus amplifying muscle power output. The period during which energy is loaded into a tendon by muscle work may be aided by a catch mechanism tha...

BPC 157, a pentadecapeptide derived from human gastric juice, has been demonstrated to promote the healing of different tissues, including skin, muscle, bone, ligament and tendon in many animal studies. However, the underlying mechanism has not been fully clarified. The present study aimed to explore the effect of BPC 157 on tendon fibroblasts isolated from Achilles tendon of male Sprague-Dawle...

Chronic patellar tendon ruptures are a difficult clinical problem. Treatment options include repair and augmentation with hamstring tendons and other grafts. We describe a technique of extensor mechanism reconstruction using an allograft consisting of quadriceps tendon, a patellar bone block, patellar tendon, and a tibial bone block. This technique is a salvage procedure indicated only in the m...

The plantaris muscle originates from the lateral supracondylar line of the femur in the posterior of the knee and courses distally in an inferomedial direction near the medial head of the gastrocnemius and along themedial border of the Achilles tendon. The tendon of the plantaris muscle either inserts with the Achilles tendon or can have its own independent insertion on the calcaneus (4). The m...

MM Al-Qattan, HM Clarke, V Bowen. Conservative management of transverse partial flexor digitorum profundus tendon lacerations in zone 2. Can J Plast Surg 1995;3(3):157-160. The experience with six patients managed conservatively following transverse partial flexor digitorum profundus tendon lacerations in zone 2 is presented. Four patients who were mobilized using elastic traction experienced n...

Chronic disruption of the extensor mechanism is a devastating problem after total knee arthroplasty. Quadriceps tendon ruptures occur at an estimated 0.1% prevalence in the setting of total knee arthroplasty. Complete tears of the quadriceps tendon generally have poor results and high rates of rerupture. We present a case of a quadriceps tendon rupture after total knee arthroplasty which rerupt...

The present study investigated the mechanical role of the dorsoventral curvature of the Achilles tendon in the conversion of the shortening of the plantarflexor muscles into ankle joint rotation. Dynamic, sagittal-plane magnetic resonance spin-tagged images of the ankle joint were acquired in six healthy subjects during both passive and active plantarflexion movements driven by a magnetic reson...
