A Convergent Tibial Tunnel Technique for Concomitant Anterior Cruciate Ligament Reconstruction and Meniscal Root Repair.

Modern arthroscopic knee-reconstruction techniques involve the use of multiple bone tunnels and fixation devices to restore the anatomy and stability of the knee after traumatic injury. In these injuries, however, tunnel collision can be problematic, especially when combining anterior cruciate ligament reconstruction with meniscal root repairs or multiligament reconstructions. We describe a multiple tibial tunnel technique to allow fixation of both anterior cruciate ligament graft and meniscal roots through convergence to a single tibial cortical aperture.

A comparison of stiffness of six knee braces with application for posterolateral corner reconstructions.

Posterolateral corner knee injuries are clinically significant, and often require surgical reconstruction. The optimal knee brace following posterolateral corner reconstructions has not yet been determined via clinical nor biomechanical study. We sought to evaluate the stiffness of six types of knee braces to determine the ideal brace type for reducing varus forces, which may have clinical utility for posterolateral corner knee reconstruction rehabilitation.

A Ten-Year Radiostereometric Analysis of Polyethylene Wear Between Oxidized Zirconium and Cobalt Chrome Articulations in Total Hip Arthroplasty.

Background: Oxidized zirconium (OxZi) femoral heads combine the decreased abrasive properties of ceramics with the toughness of metal alloys to lower wear and increase the durability of total hip arthroplasty. The purpose of this study was to compare the 10-year polyethylene wear rates between OxZi/XLPE and cobalt chrome (CoCr)/XLPE articulations.

Methods: A radiostereometric analysis (RSA) was performed on two cohorts of 23 patients who underwent total hip arthroplasty using either OxZi/XLPE or CoCr/XLPE at a minimum of 10-year follow-up.

Comparative study of outcomes for elderly hip fractures presenting directly to a referral hospital versus those transferred from peripheral centres.

Background: The geography of rural Australia poses a myriad of logistical dilemmas, including the provision of timely access to emergency orthopaedic hip fracture surgery. Current guidelines support surgery within 48 h, and delays to transfer to a referral hospital may result in worse outcomes and increase mortality rates. The aim of this study was to examine the effect of transfer delays on the clinical outcomes of hip fractures in a rural setting.

Natural history of medial clavicle fractures.

Background: Fractures of the medial third of the clavicle comprise less than 3% of all clavicle fractures. The natural history and optimal management of these rare injuries are unknown. The aim of our study is to describe the demographics, management and outcomes of patients with medial clavicle fractures treated at a Level 1 Trauma Centre.

'Beware the lump in the foot!': predictors of recurrence and survival in bone and soft-tissue sarcomas of the foot and ankle.

Background: Although benign lumps around the foot and ankle are common, sarcomas in this area are frequently missed, and the consequences can be disastrous. Patients are often referred to tumour centres after suboptimal prior surgical excision. The predictors of local recurrence, metastasis and survival in this cohort have yet to be elucidated.
