OBJECTIVES To evaluate the prevalence of a vascular network adjacent to the insertion of the pes anserinus, so that it could be used as an anatomical reference point to facilitate harvesting flexor grafts for arthroscopic reconstruction of the anterior cruciate ligament (ACL). METHODS Thirty patients with ACL tears who were going to undergo ACL reconstruction using the tendons of the semitend...

The volume occupied by the extracellular space has been investigated in six types of voluntary muscles: sartorius (frog), semitendinosus (frog), tibialis anticus longus (frog), iliofibularis (frog), rectus abdominis (frog), and diaphragm (rat). With the aid of four types of probe material, three of which are conventionally employed (inulin, sorbitol, sucrose) and one of which is newly introduce...

In cross-sections of single fibers from the frog semitendinosus muscle the number of thick myofilaments per unit area (packing density) is a direct function of the sarcomere length. Our data, derived from electron microscopic studies, fit well with other data derived from in vivo, low-angle X-ray diffraction studies of whole semitendinosus muscles. The data are consistent with the assumption th...

The purpose of this study was to evaluate the existence of differences in the rehabilitation of patients after ACL reconstruction using bone-patellar tendon-bone graft and the four-strand semitendinosus and gracilis tendon grafts, through a literature revision. The researched databases were MEDLINE, EMBASE, LILACS, COCHRANE and PEDro. The inclusion criteria were published studies with methodolo...

The semitendinosus muscle has a unique anatomical structure. Its long and strong distal tendon is frequently selected as a material for autogenous grafts in anterior cruciate ligament reconstruction. The article provides an overview of literature concerning the little known process of spontaneous regeneration of the semitendinosus tendon after its harvesting. Subsequent to harvesting, the muscl...
