Background: Despite the importance of hamstring tendon autograft, one major disadvantage in applying this technique in the surgical reconstruction of anterior cruciate ligament is individual variability in the tendon diameter. Hence, the purpose of the present study was to use anthropometric parameters such as gender, height and body mass index to predict 4-strand (quadruple) hamstring ten...

+MacLeod, T D; Snyder-Mackler, L; Axe, M J; Buchanan, T S + Center for Biomedical Engineering Research, University of Delaware, DE [email protected] ABSTRACT INTRODUCTION: Anterior cruciate ligament (ACL) reconstruction is commonly performed with a cadaveric allograft (ALLO) or a hamstring semitendinosus-gracilis (STG) autograft. Knee flexor strength deficits following STG reconstruction are a g...

Introduction Old neglected posterior type of elbow dislocations is not very common and generally requires open reduction. It was usually treated with open reduction and K-wire stabilization. We did a newer method in which in addition cruciate type ligament reconstruction; we have reconstructed lateral ulnar collateral ligament (LUCL) and UCL (medial collateral ligament) using semitendinosus gra...

In order to obtain broader insights into the equine musculoskeletal system, we studied the fibre type composition of 2 locomotory muscles in biopsies from Dutch Warmblood foals taken at 3 different ages in the first year postpartum. The muscle fibre types were determined histochemically as well as immunohistochemically. ATPase-characterised IIB fibres appear to express either IId or type lIa pl...

The relationship between semitendinosus muscle force and knee joint kinematics during isometric torque production was examined in the frog (Rana pipiens) hindlimb. Passive muscle sarcomere length was monitored by laser diffraction during knee rotation, and joint center of rotation was determined later using principles of rigid body kinematics. Contractile force at the distal tibia, resulting fr...

The calmodulin/Ca2+-dependent serine/threonine phophatase, calcineurin (CaN), has been implicated in controlling muscle fiber phenotype. However, little information is available concerning the expression of CaN in porcine skeletal muscle. Therefore, the porcine CaN alpha (CaN-A) was cloned by reverse transcription-PCR and its expression characterized in selected porcine skeletal muscles. We suc...

OBJECTIVE To evaluate the surgical aspects that may offer good anatomic and functional results in posterior cruciate ligament (PCL) reconstruction using an autologous graft of the quadriceps tendon and double semitendinosus through a double femoral tunnel. METHODS Fourteen patients with isolated PCL lesions, instability and pain were operated on by arthroscopy and evaluated according to the I...
