OBJECTIVE To verify whether the combination of tibial cross pin fixation and femoral screw fixation presents biomechanical advantages when compared to femoral cross pin fixation and tibial screw fixation for the reconstruction of the anterior cruciate ligament (ACL). METHODS Thirty-eight porcine knees and bovine extensor digitorum tendons were used as the graft materials. The tests were perfo...

bone-patellar tendon auto graft is probably the most widely used graft for acl reconstruction. several methods for graft fixation have been described. to avoid intra-articular hardware we adopt biological fixation with a femoral trapezoidal press-fit fixation. a prospective study was performed on 30 consecutive active people who underwent acl reconstruction with this technique by two surgeons b...

  Background: No uniform consensus exists to decide type of fixation for arthroscopic anterior cruciate ligament reconstruction. Hypothsis: There is similar functional outcome after rigid fix compared to other methods of fixation which has been published. Study design: Retrospective observational study. Methods: A total of 50 patients underwent arthroscopic anterior cruciate ligament reconstruc...

The purpose of this study was to compare clinical and radiological outcomes of the first 191 fully porous-coated hip resurfacing arthroplasties with 96 hybrid hip resurfacing arthroplasties performed during the same period at a minimum 2-year follow-up to evaluate the initial fixation of uncemented femoral resurfacing components. The results of this study indicate that fully porous-coated femor...

BACKGROUND Recommendations for bone tunnel placement during anterior cruciate ligament (ACL) reconstruction have become more precise. However, these recommendations differ neither with the choice of graft nor with the method of fixation used. The influence of the method of femoral fixation used on the biomechanical function of a soft tissue ACL graft remains unknown. HYPOTHESIS Our null hypot...

Controversy exists regarding the optimal method of fixation for primary total hip replacement, particularly the femoral component. We performed a systematic literature review to explore whether cemented total hip replacement can achieve better clinical and radiological outcomes. A total of 29 publications were selected using computer-aided and manual searches. A qualitative comparison of result...

BACKGROUND Femoral neck fractures typically occur as a result of high-energy mechanisms among non-geriatric patients. Complications, including femoral neck shortening, non-union, and avascular necrosis, are relatively common after the internal fixation of this fracture pattern. These complications have serious effects on young patients. The Pauwels classification, which is the first biomechanic...

OBJECTIVE The less invasive surgical stabilisation (LISS) plate fixation method is an orthopaedic procedure for the fixation of distal femoral fractures. Early physiotherapy treatments of motion and mobilisation have been advocated following this procedure. This article critically appraises the evidence base assessing the early rehabilitation of patients following LISS fixation for distal femor...

This review considers methods used to quantify lag screw placement within the femoral head following proximal femoral fracture. Implants used for fixation of femoral neck fractures can lead to unwanted outcomes in some patients. Cutting out of the screw within the femoral head has been shown to be the commonest cause of failure and is related to lag screw placement within the femur. Until now, ...
