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 tendons ...

PURPOSE During the early postoperative period, the stability of the fixation of a hamstring graft to the bone tunnel is the primary factor in limiting rehabilitation. The aim of this study was to evaluate if the initial fixation strength of a new suspension screw is comparable to that of the biodegradable interference screw fixation technique in the hamstring reconstruction of the anterior cruc...

Despite the popularity of anterior cruciate ligament (ACL) reconstruction procedures, the ideal graft for reconstruction remains a matter of controversy. The ideal graft for ACL reconstruction should have histologic and biomechanical characteristics similar to those of the native ACL; should be quickly and fully incorporated within the bony tunnels; should maintain its viscoelastic properties f...

BACKGROUND Tibial fixation of hamstring tendon grafts has been the weak link in anterior cruciate ligament reconstruction. HYPOTHESIS Use of a central four-quadrant sleeve and screw provides superior fixation when compared with standard interference screw fixation. STUDY DESIGN Controlled laboratory study. METHODS In eight pairs of cadaveric knees each anterior cruciate ligament was recon...

Purpose To assess graft slippage at the site of femoral fixation by follow-up magnetic resonance imaging (MRI) after anterior cruciate ligament (ACL) reconstruction with a four-strand autogenous hamstring tendon using RigidFix (DePuy Mitek). Materials and Methods Twenty-one subjects diagnosed with ACL rupture underwent ACL reconstruction using hamstring autograft with the transtibial techniqu...

PURPOSE Sensory disturbance around the surgical incision due to injury of the infrapatellar branch of the saphenous nerve can be seen in the anterior cruciate ligament reconstruction. In this research, we aimed to compare the incidence, extent of sensory loss, its clinical effect, and natural course caused by two different skin incisions used for hamstring graft harvest. METHODS Vertical inci...

We describe a case of painful snapping in the medial aspect of the knee of a 40-year-old man, following a knee hyperflexion injury. Dynamic real-time ultrasonography determined that the snapping was due to the distal tendon of sartorius passing over a medial meniscal cyst. The patient subsequently underwent arthroscopic decompression of the cyst instead of an inappropriate hamstring tendon harv...

Objectives The complications associated with iliac crest bone-graft harvest have resulted in the development of alternative harvest sites. Lower extremity alternative sites that have been reported for foot and ankle procedures include greater trochanter, proximal tibia, distal tibia, and calcaneus. These sites have been studied in terms of complications, postoperative pain, and quality of the h...

Background: The anterior half of the peroneus longus tendon (AHPLT) has recently gained popularity to become alternate graft choice for cruciate ligament reconstruction due its acceptable biomechanical properties, easy and safe harvest. Methods: A retrospective study was conducted compare results (ACL) with AHPLT hamstring at minimum 3 years follow-up. Knee stability, International Documentatio...

BACKGROUND The results of revision anterior cruciate ligament reconstruction are limited in the current literature, and no studies have previously documented the outcome of revision anterior cruciate ligament reconstruction using solely hamstring tendon grafts. HYPOTHESIS Revision anterior cruciate ligament reconstruction with 4-strand hamstring tendon graft affords acceptable results and is ...
