Proximal tibial fracture following anterior cruciate ligament reconstruction surgery: a biomechanical analysis of the tibial tunnel as a stress riser.

Purpose: This is the first biomechanical study to examine the potential stress riser effect of the tibial tunnel or tunnels after ACL reconstruction surgery. In keeping with literature, the primary hypothesis tested in this study was that the tibial tunnel acts as a stress riser for fracture propagation. Secondary hypotheses were that the stress riser effect increases with the size of the tunnel (8 vs.

Radiographic and clinical analysis of pelvic triple osteotomy for adult hip dysplasia.

Background: Adult Hip Dysplasia (AHD) has been strongly linked with the development of hip osteoarthritis. The complexity and therefore resultant steep learning curve of the Bernese osteotomy for AHD has been well described. The purpose of this study was to analyse the efficacy of a technically less demanding interlocking pelvic triple osteotomy.
