Objective- To determine the effect of collagen type I on hydroxyproline content in Achilles tendon in dogs. Design- Experimental in vivo study. Animals- A total of 12 adult dogs. Procedure- Under general anesthesia and aseptic condition the dorsal surface of right Achilles tendon was exposed and after complete separation of connective tissue, it was splitted (striking 10 times) in full thic...
An Achilles tendon allograft with its bony calcaneal attachment was successfully used to repair a spontaneous rupture of a severely degenerative and irreparable Achilles tendon. After 18 months of follow-up, the patient is satisfied and the Achilles tendon power has returned to a normal level.
The purpose of this study was to evaluate the surgical outcomes of reconstruction of chronic Achilles tendon ruptures using various methods, including Achilles tendon allograft. Between October 2003 and March 2010, twelve patients with chronic Achilles tendon ruptures and a defect gap of >4 cm underwent surgical reconstruction with V-Y advancement, gastrocnemius fascial turn-down flap, flexor h...
Objective * These authors contributed equally to this work. To explore tendon-bundle technique for treating Achilles tendon rupture with no defects. Methods Patients with full unilateral Achilles tendon rupture with no defects were included. The Achilles tendon medial edge surgical repair approach was used, revealing horsetail-like rupture bundles. Tendon bundles were anatomically realigned and...
Purpose To ascertain in cadavers where the sural nerve crosses the gastro-soleus complex and where the gastrocnemius tendon merges with the Achilles tendon in relation to the calcaneal tuberosities. Methods Twelve cadaveric lower limbs (6 right and 6 left) were dissected. The distances between the calcaneal tuberosities and the lateral border of the Achilles tendon where the sural nerve cross...
OBJECTIVE This study was undertaken to examine whether bone morphogenetic protein 7 (BMP-7) induces ectopic cartilage formation in the rat tendon, and whether transplantation of tendon treated with BMP-7 promotes meniscal regeneration. Additionally, we analyzed the relative contributions of host and donor cells on the healing process after tendon transplantation in a rat model. METHODS BMP-7 ...
BACKGROUND Chronic Achilles tendon tears could hinder patients and represent a challenge to surgeons. Although many different surgical techniques have been proposed for reconstruction of a neglected Achilles tendon rupture, there is no clear evidence to support one technique over the others, but the use of a technique that could allow for an "anatomical" reconstructions seems desirable. METHO...
The elastic properties of the human Achilles tendon are important for locomotion; however, in vitro tests suggest that repeated cyclic contractions lead to tendon fatigue - an increase in length in response to stress applied. In vivo experiments have not, however, demonstrated mechanical fatigue in the Achilles tendon, possibly due to the limitations of using two-dimensional ultrasound imaging ...
INTRODUCTION Deep infection after reconstruction of chronic Achilles tendon rupture is a major and intractable complication. CASE REPORT We report a case of late deep infection following a surgery for chronic Achilles tendon rupture, and its simple and successful treatment with negative pressure wound therapy (NPWT). Six months following the reconstruction of chronic Achilles tendon rupture, ...
OBJECTIVE To measure the biomechanical effects of immobilization on the Achilles' tendon. DESIGN Experimental, controlled study. SETTING Physiatry research laboratory. ANIMALS Twenty adult rabbits. INTERVENTION One hindlimb immobilized in a cast for 4 weeks (n=10) or 8 weeks (n=10). The contralateral legs (n=20) served as controls. MAIN OUTCOME MEASURES Cross-sectional Achilles' tendo...
