INTRODUCTION: The hamstring tendon autograft is widely used for anterior cruciate ligament reconstruction because of its superior tensile strength and lower donor site morbidity. The successful reconstruction surgery depends on not only initial graft fixation but also biologic integration of the graft. The healing process of transplanted tendon graft to bone via the development of fibrovascular...

BACKGROUND The decision as to whether or not an athlete is ready to return to sport (RTS) after ACL reconstruction is difficult as the commonly used RTS criteria have not been validated. PURPOSE To evaluate whether a set of objective discharge criteria, including muscle strength and functional tests, are associated with risk of ACL graft rupture after RTS. MATERIALS AND METHODS 158 male pro...

BACKGROUND AND OBJECTIVES Graft harvest with or without the middle hepatic vein (MHV) affects venous return and function of the remaining liver. The aims of this study are to compare the remnant liver volume and spleen changes in the donors of different types of graft harvest and to evaluate the influence of resection with or without the MHV on the remnant liver volume regeneration, spleen volu...

Although regarded as a gold standard, harvesting of autologous bone graft is associated with donor site morbidity and a number of complications. An alternative is allograft with limited availability as the main shortcoming. Femoral heads as allografts are now routinely obtained during total hip arthroplasty. A small but valuable amount of pure cancellous bone graft of high quality can be obtain...

OBJECTIVE This study aims to present the graft pathology at the time of harvest and its impact on long-term survival. METHODS The remnants of the bypass grafts from 66 consecutive patients with coronary artery disease receiving a coronary artery bypass grafting were investigated pathologically, and pertinent predictive risk factors and survival were analyzed. RESULTS Medial degenerative cha...

UNLABELLED The purpose of this cadaver study about the ACL graft was to compare a "Lateral Tibial Tunnel" (LTT) and a "classic, anteroMedial Tibial Tunnel" (MTT), as to fixation strength and mode of failure. Ten pairs of fresh frozen human proximal tibias were used. In one of both tibias a classic anteromedial tunnel was used, versus a lateral tibial tunnel in the contralateral knee. Autologous...

From individual randomized studies, it is unclear whether patellar tendon grafts or hamstring tendon grafts yield the best functional results after ACL reconstruction. Therefore, we performed a meta-analysis to provide quantitative data to compare patellar with hamstring grafts after ACL reconstruction with regard to knee function. We searched computerized databases for randomized controlled tr...

The Four-Strand Hamstring Tendon Autograft has been long established as the gold standard for surgical reconstruction of the Anterior Cruciate Ligament. Some studies have suggested wider grafts, such as a Five-Strand hamstring graft, may provide greater strength and a larger scaffold for incorporation of the graft into the bone tunnels, leading to greater postoperative anterior stability of the...

OBJECTIVE To compare the incidence of peri-incisional dysesthesia according to the skin incision technique for hamstring tendon graft harvest in anterior cruciate ligament reconstruction. METHODS Thirty-three patients with ACL rupture were separated in two groups: group 1, with 19 patients submitted to the oblique skin incision to access the hamstrings and group 2-14 patients operated by vert...
