To evaluate whether pre-operative anthropometric data can predict the optimal diameter and length of hamstring tendon autograft for anterior cruciate ligament (ACL) reconstruction. This was a cohort study that involved 169 patients who underwent single-bundle ACL reconstruction (single surgeon) with 4-stranded MM Gracilis and MM Semi-Tendinosus autografts. Height, weight, body mass index (BMI),...

Background: Hamstring tendons are secondary hip extensors. Their harvest for graft in anterior cruciate ligament(ACL) reconstruction may create deleterious effect on hip extension strength. This is of particular importance in sportsthat need powerful hip extension force like climbing and sprinting. Due to scarcity of a comprehensive study in thisarea, we designed this prospect...

A bilateral anterior cruciate ligament (ACL) tear is one of the rare injuries that seen in orthopaedics practice. Although few single-staged ACL ruptures have also been documented, most happen on two different occasions. there isn't a clear consensus, accounts both and two-staged reconstruction literature. This case report provides surgeons with options to consider while treating this unusual i...

BACKGROUND A growing body of evidence indicates that in patients after anterior cruciate ligament reconstruction (ACLR) with a combined semitendinosus and gracilis (STGR) graft there are large deficits in the internal rotation strength, which has led some authors to recommend harvest of only ST tendon whenever possible. The purpose of this study was to assess the isometric (IT) and peak torque ...

functional and aesthetic results [3]. In case of more extensive defects involving both scrotal and perineal skin loss, we favor split thickness skin grafts for defect coverage. As noted by Huettinger et al. [1], graft fixation remains a challenge. We have developed a VAC fixation technique, the so-called “sandwich technique” [4], that we have used successfully for many years now. We feel that i...

BACKGROUND Strength of graft fixation is the weakest link in anterior cruciate ligament reconstruction. HYPOTHESIS There is no difference in initial fixation strength between different hamstring tendon graft femoral fixation devices. STUDY DESIGN Randomized experimental study. METHODS Each of six devices was used in the fixation of 10 quadrupled human semitendinosus-gracilis tendon grafts...

OBJECTIVE Treating brachial plexus injuries is a major challenge, especially lesions that are presented late, with more than 12 months of evolution. We retrospectively analyzed patients who underwent one of the possibilities for attempting to restore the function of upper limbs affected under such conditions: microsurgical transfer of the gracilis muscle for elbow flexion. METHODS Eight patie...

The myotendinous junction (MTJ) is a specialized structure in the musculotendinous system, where force is transmitted from muscle to tendon. Animal models have shown that the MTJ takes form of tendon finger-like processes merging with muscle tissue. The human MTJ is largely unknown and has never been described in three dimensions (3D). The aim of this study was to describe the ultrastructure of...
