Comparison of Gliding Resistance of Tendons about the Ankle

چکیده
INTRODUCTION: The etiology of posterior tibial tendon dysfunction (PTTD) is unclear although it has been suggested that it may be related to a preexisting flexible flatfoot. Obesity, diabetes, and hypertension may increase the risk of PTTD according to epidemiological studies. It is uncertain how tendonopathy can severely affect the PT tendon, while adjacent tendons, flexor digitorum longus (FDL) and flexor hallucis longus (FHL), are unaffected. We propose that mechanical resistance in the gliding portion of the PT tendon is significantly greater than FDL and FHL. The purpose of this study is to compare the gliding resistance of PT, FDL, and FHL in intact and flatfoot conditions, and in different ankle poitions. We hypothesize that the PT gliding resistance is greater than FDL and FHL in all testing conditions.

The Effect of Lubricin on the Gliding Resistance of Mouse Intrasynovial Tendon
The purpose of this study was to investigate the role of lubricin on the gliding resistance of intrasynovial tendons by comparing lubricin knockout, heterozygous, and wild type mice. A total of thirty-six deep digital flexor (DDF) tendons in the third digits of each hind paw from eighteen adult mice were used, including six lubricin knockout mice (Prg4 -/-), six heterozygous mice (Prg4 +/-), an...

This study investigated the effects of lubricin on the gliding of repaired flexor digitorum profundus (FDP) tendons in vitro. Canine FDP tendons were completely lacerated, repaired with a modified Pennington technique, and treated with one of the following solutions: saline, carbodiimide derivatized gelatin/hyaluronic acid (cd-HA-gelatin), carbodiimide derivatized gelatin to which lubricin was ...

PURPOSE To investigate the effects of tendon surface treatment using hyaluronic acid (HA) and lubricin on the gliding resistance of human extrasynovial palmaris longus (PL) tendon in vitro. METHODS Thirty-two fresh-frozen cadaver human fingers and 16 ipsilateral PL tendons were used. Each PL tendon was divided into 2 pieces, which were randomly assigned into 4 experimental groups. After the g...
متن کاملHuman synoviocyte lubricin and bovine synovial fluid lubricin equally improve gliding resistance in a canine model in vitro.
The lubricating ability of human synoviocyte lubricin and bovine lubricin purified from synovial fluid was investigated and compared using a canine in vitro tendon model. Our null hypothesis was that these two forms of lubricin would have equal lubricating ability. Forty two canine hind-limbs were used. The peroneus longus (PL) tendons were harvested, along with the proximal phalanx and flexor ...
متن کاملRepopulation of intrasynovial flexor tendon allograft with bone marrow stromal cells: an ex vivo model.
PURPOSE Delayed healing is a common problem whenever tendon allografts are used for tendon or ligament reconstruction. Repopulating the allograft with host cells may accelerate tendon regeneration, but cell penetration into the allograft tendon is limited. Processing the tendon surface with slits that guide cells into the allograft substrate may improve healing. The purpose of this study was to...
