BACKGROUND Stable and well-aligned placement of tibial components during primary total knee arthroplasty is challenging in patients with bone defects. Although rectangular block-shaped augmentations are widely used to reduce the shearing force between the tibial tray and bone compared with wedge-shaped augmentations, the clinical result remains unclear.(More)
OBJECTIVE The aim of the study was to compare the dislocation rate between total hip arthroplasty (THA) via direct anterior approach (DAA) and via posterior approach (PA). METHODS We compared a consecutive series of 139 THAs via DAA with 177 THAs via PA. All study patients received ceramic-on-ceramic bearing surfaces and similar uncemented prostheses.(More)
BACKGROUND Fixed angle sliding hip screw devices allow controlled impaction between the head neck fragment and the femoral shaft fragment in the surgical treatment of pertrochanteric fractures. This study was performed to evaluate the frequency and pattern of comminution at the fracture site, which may prevent the intended impaction. MATERIALS AND METHODS(More)
UNLABELLED There is conflicting evidence about the benefit of using corticosteroid in periarticular injections for pain relief after total knee arthroplasty (TKA). We carried out a double-blinded, randomised controlled trial to assess the efficacy of using corticosteroid in a periarticular injection to control pain after TKA. A total of 77 patients, 67(More)
