Hamstring tendon harvesting. Reviewing anatomic relationships and avoiding pitfalls.
The gracilis and semitendinosus tendons remain popular grafts for many reconstructive procedures, including anterior cruciate ligament reconstruction. Surgeons who use other grafts for ACL reconstruction should have the hamstring tendon techniques in their arsenal in the event other grafts are unavailable or undesirable. Detailed knowledge of the anatomy of the medial side of the knee is paramo...
متن کاملElectromechanical delay of the knee flexor muscles is impaired after harvesting hamstring tendons for anterior cruciate ligament reconstruction.
BACKGROUND Changes in electromechanical delay during muscle activation are expected when there are substantial alterations in the structural properties of the musculotendinous tissue. In anterior cruciate ligament reconstruction, specific tendons are being harvested for grafts. Thus, there is an associated scar tissue development at the tendon that may affect the corresponding electromechanical...
متن کاملSingle-tunnel double-bundle anterior cruciate ligament reconstruction with anatomical placement of hamstring tendon graft: can it restore normal knee joint kinematics?
BACKGROUND Anatomical reconstruction techniques that can restore normal joint kinematics without increasing surgical complications could potentially improve clinical outcomes and help manage anterior cruciate ligament injuries more efficiently. HYPOTHESIS Single-tunnel double-bundle anterior cruciate ligament reconstruction with anatomical placement of hamstring tendon graft can more closely ...
متن کاملAnterior Cruciate Ligament Reconstruction with Hamstring Tendons Has no Deleterious Effect on Hip Extension Strength
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...
متن کاملElectrophysiological Assessment of Injury to the Infra-patellar Branch(es) of the Saphenous Nerve during Anterior Cruciate Ligament Reconstruction Using Medial Hamstring Auto-grafts: Vertical versus Oblique Harvest Site Incisions
BACKGROUND It was suggested that the direction of incision for medial hamstring tendons harvesting influences the incidence of injury to the infrapatellar branch of the saphenous nerve (IPBSN), a common complication following arthroscopically-assisted anterior cruciate ligament reconstruction (ACLR). OBJECTIVES The main purpose of current study was to compare the incidence of IPBSN injury bet...
