The purpose of this study was to evaluate the predictive value MRI in determining hamstring autograft size preoperatively for pediatric ACL reconstructions. Children and adolescents from 10-20 years old that had undergone reconstruction using were identified 2017-2018. Semitendinosus gracilis cross-sectional area diameter measured on preoperative knee MRIs field interest (FOI) distance measurem...

Background: Baseball pitching is a dynamic movement where the lower extremities generate and sequentially transfer energy to upper maximize ball velocity. The need for body muscular strength produce adequate push-off landing forces has been documented; however, influence footwear surface inclination on muscle activation remains unknown. Objectives: Determine how in molded cleats turf shoes from...

The question of which graft to use for anterior cruciate ligament (ACL) reconstruction continues to be debated at meetings around the world. The overall choice of grafts consists of autografts, allografts, and synthetic grafts. By far the two most commonly used grafts are central third bone-patellar tendon-bone and hamstring tendon, either semitendinosus alone or semitendinosus combined with gr...

Anterior cruciate ligament (ACL)-deficient knees have impaired proprioception, and, although mechanoreceptors have been found in the ACL, the existence of a reflex elicited from these receptors has not been directly demonstrated in humans. In eight patients that underwent knee arthroscopy and had no sign of ACL disease, thin wire electrodes were inserted into the proximal and mid parts of the A...

The longitudinal impedance of single skeletal muscle fibers has been measured from1 to 10,000 Hz in an oil gap apparatus which forces current to flow longitudinally down the fiber. The impedance observed is purely resistive in some fibers from the semitendinosus muscle and in two fibers from the sartorius muscle. In other fibers from the semitendinosus muscle a small phase shift is observed. Th...

During routine cadaveric dissection for the undergraduate students in the Department of Anatomy, we noted multiple muscular variations in a middle-aged male cadaver. All the variations were seen at the back of thigh (flexor compartment) of right lower limb. An anomalous muscle of 17 cm length with average width of 1.5 cm. was inserted to the semitendinosus, a third head of biceps femoris of 6.5...

Introduction The hamstring muscles are frequently implicated in posterior thigh pain due to strains. The hamstring muscles are the three most superficial muscles that span the posterior thigh, and consist of the biceps femoris, semitendinosus, and semimembranosus. The long head of biceps femoris originates from the inferiomedial aspect of the ischial tuberosity and inserts into the head of the ...

OBJECTIVE To demonstrate the results obtained from foot and ankle tendon reconstructions using the tendon of the semitendinosus muscle. The clinical results, the patient's degree of satisfaction and complications in the graft donor and recipient areas were evaluated. METHODS This was a retrospective study in which the medical files of 38 patients who underwent this surgical procedure between ...

The purpose of this anatomical study was to explore the morphological variations of the semitendinosus and gracilis tendons in length and cross-section and the statistical relationship between length, cross-section, and body height. We studied the legs of 93 humans in 136 cadavers. In 43 specimens (46.2%) it was possible to harvest the tendons from both legs. We found considerable differences i...
