Despite general agreement on the effects of knee valgus and internal tibial rotation on anterior cruciate ligament (ACL) loading, compelling debate persists on the interrelationship between these rotations and how they contribute to the multi-planar ACL injury mechanism. This study investigates coupling between knee valgus and internal tibial rotation and their effects on ACL strain as a quanti...

BACKGROUND Internal tibial rotation is a risk factor for anterior cruciate ligament (ACL) injury. The effect of restraining tibial rotation (RTR) to prevent ACL injury during single-leg landing is not well understood. We aimed to investigate the effect of impact load and RTR on ACL injury with respect to flexion angle. We hypothesized that RTR could protect the knee from ACL injury compared to ...

OBJECTIVE To describe the typical tibial diaphyseal fracture ("footballer's fracture") and to clarify the circumstances and mechanism of the injury. METHODS In an attempt to obtain a detailed analysis of the types of injury suffered, and thereby highlight areas for prevention, 100 consecutive adult football players with a tibial diaphyseal fracture were studied prospectively. Details of the c...

Fractures of the Proximal tibial epiphysis are rare. We report a case of proximal tibial epiphyseal fracture with completely separated and displaced physis . The injury was a result of high speed road traffic accident. The fracture displacement was such that it was difficult to put it in any existing classification system except poland type 4. The injury has a high risk of neurovascular comprom...

BACKGROUND The functional disability and high costs of treating anterior cruciate ligament (ACL) injuries have generated a great deal of interest in understanding the mechanism of noncontact ACL injuries. Secondary bone bruises have been reported in over 80% of partial and complete ACL ruptures. PURPOSE The objectives of this study were (1) to quantify ACL strain under a range of physiologica...

The aim was to compare fear of re-injury, patient reported function, static and dynamic tibial translation and muscle strength assessed before and 5 weeks after an anterior cruciate ligament (ACL) reconstruction between individuals who sustained a subsequent ACL graft rupture or a contralateral ACL injury within 5 years after the reconstruction, and individuals with no subsequent injury. Ninete...

Injuries of the proximal tibial epiphysis are rare. They predominantly occur in adolescent males following, signfficant trauma. They usually involve a Salter Harris Type II, III or IV injury, and are associated with a high level of growth disturbance. We present the case of a twelve year old boy, who suffered a Type I proximal tibial epiphyseal injury. The mechanism of injury has not been previ...

background: the treatment of open tibial fractures is still an orthopaedic challenge and full of complications. in many cases the use of external fixator that has been known as a non-:union: machine is obligatory with a high incidence of pin track infection and other complications. the aim of this study was to compare the use of external fixation as a definite method for treatment of open tibia...
