BACKGROUND Novel interventions that can safely and effectively overload muscle early following anterior cruciate ligament reconstruction are needed to minimize atrophy and weakness that often becomes longstanding. EVIDENCE ACQUISITION Eccentrically induced forces can be safely applied during the early stages of rehabilitation following surgery and serve as a potent stimulus for increasing mus...

Autologous bone-patellar tendon-bone autograft is a common choice for anterior cruciate ligament reconstruction and from both biologic and biomechanical perspectives is well-suited for this purpose. A centrally harvested, 10 mm wide patellar tendon graft has an estimated initial load-to-failure of 2977 N, and interference screw fixation of associated bone blocks provides initial pull-out streng...

The purpose of this study was to dynamically assess the functional outcome of patients who had undergone successful anterior cruciate ligament reconstruction using an autologous patellar tendon technique and to determine whether their dynamic knee function was related to quadriceps and hamstring muscle strength. The knee kinematics and kinetics of 22 subjects who had undergone anterior cruciate...

BACKGROUND Many individuals do not resume unrestricted, preinjury sports participation after anterior cruciate ligament reconstruction, thus a better understanding of factors associated with function is needed. The purpose of this study was to investigate the association of knee impairment and psychological variables with function in subjects with anterior cruciate ligament reconstruction. HY...

BACKGROUND Noncontact anterior cruciate ligament injuries occur two to eight times more often in women than in men. Changes in ligament laxity and strength have been associated with female hormones such as relaxin. HYPOTHESIS Relaxin receptors are present within the female anterior cruciate ligament. STUDY DESIGN Controlled laboratory study. METHODS Remnants of anterior cruciate ligament ...

BACKGROUND Following anterior cruciate ligament injury and subsequent reconstruction transverse plane tibiofemoral rotation becomes underconstrained and overconstrained, respectively. Conflicting reports exist on how rotations influence loading at the knee. This investigation aimed to determine the mechanical effects of internal and external tibial rotation offsets on knee kinematics and ligame...

conclusions ipbsn injury is a common complication following arthroscopically-assisted aclr and, ifn not significant, oblique direction of the incision is associated with decreasedn incidence of the injury. ipbsn injury has no effect on the function but because of then disturbance with patients' satisfaction, authors believe the oblique incision isn preferable to avoid the nerve injury during me...

background :disruption of anterior cruciate ligament (acl) is a common ligamentous injury of the knee. the choice of graft for (acl) reconstruction remains controversial. this prospective, randomized clinical trial aimed to compare clinical results of bone-patellar tendon-bone (bptb) grafts and four-strand semitendinosus-gracilis (st) grafts for acl reconstruction over a 3-year follow-up interv...

Injuries to the medial collateral ligament (MCL) are very common and there seems to be a consensus supporting the conservative management of grade I and II tears. Grade III tears are also usually treated conservatively unless associated with injuries to the anterior cruciate ligament or posterior cruciate ligament. This article outlines rehabilitation programs for conservative treatment of MCL ...
