REVIEW
Min Lu, Erik Nathan Hansen
As the burden of deep hardware infections continues to rise in orthopaedics, there is increasing interest in strategies for more effective debridement of colonized tissues and biofilm. Hydrogen peroxide has been used medically for almost a century, but its applications in orthopaedic surgery have yet to be fully determined. The basic science and clinical research on the antiseptic efficacy of hydrogen peroxide have demonstrated its efficacy against bacteria, and it has demonstrated potential synergy with other irrigation solutions such as chlorhexidine and povidone-iodine...

BACKGROUND: Dislocation is a leading cause of revision after primary total hip arthroplasty (THA). Although more common in the first few years after the procedure, dislocation can occur at any time. This study investigated the difference in late dislocation in ceramic-on-ceramic (CoC) bearings compared with metal-on-polyethylene and ceramic-on-polyethylene bearings in THA. METHODS: Data were used from the Australian Orthopaedic Association National Joint Replacement Registry, and the cumulative percent revision for dislocation was estimated using the Kaplan-Meier method for the different bearing surfaces...

INTRODUCTION: Severe post-traumatic ankle arthritis poses a reconstructive challenge in young and active patients. Although technically demanding and despite unsolved immunological issues, bipolar fresh total osteochondral allograft (BFTOA) represent an intriguing option to arthrodesis and prosthetic replacement. The purpose of this paper is to evaluate the outcomes of a series of 48 ankle BFTOA at 10 years follow up and to investigate the rate of survival long term. METHODS: 58 patients underwent BFTOA, of these 48 were available for follow up...

BACKGROUND: Osteotomy is a rational approach to slowing knee osteoarthritis progression by modifying loads, thereby avoiding joint replacement in younger individuals. Varus femoral osteotomy is recommended only in patients with more than 10° of valgus. The objective here was to assess outcomes of tibialvarus osteotomy in patients with lateral compartment tibio-femoral osteoarthritis and less than 10° of valgus. MATERIAL AND METHODS: A single-centre retrospective study was conducted in 19 consecutive patients managed by high tibialvarus osteotomy between January 2005 and May 2012...

This report presents the first case of a knee dislocation following septic arthritis after arthroscopy. A 65-year-old woman had an arthroscopy with irrigation and debridement (I&D) of the joint and microfracture for the chondral lesions. She had complaints of postarthroscopic infection but non-steroidal anti-inflammatory medication and local ice compression was recommended. She revisited her physician twice and at the last visit she had a large purulent effusion in her knee. The gram stain of the joint fluid aspirate demonstrated gram-positive cocci and the cultures grew methicilline-sensitive Staphylococcus aureus...

Osteolysis around joint replacements may develop due to migration of wear particles from the joint space into gaps between the interface bone and the implant where they can accumulate in high concentrations to cause tissue damage. Osteolysis may appear in various postoperative times and morphological shapes which can be generalized into linear and focal. However, there are no clear explanations on the causes of such variations. Patients' degree of sensitivity to polyethylene particles (osteolysis thresholds), the local particle concentration and the access route provided by the interface gaps have been described as determining factors...

INTRODUCTION: Primary synovial osteochondromatosis of the hip is a benign disorder, which is not frequently seen clinically. The characteristic of this disease is proliferation of synovium and formation of loose bodies inside the joint. It is known that only the loose bodies derived from synovium were called synovial osteochondromatosis. Although it can take place in any joint, the knee is most commonly affected, involvement of the hip joint is relatively rare. We report a young man who has multiple synovial osteochondromatosis in his left hip...

Taggart T Gauvain, Michael A Hames, William C McGarvey
One of the main challenges in ankle replacement is correction of any deformities in the operative limb. Deformity can be found proximal and distal to the ankle joint as well as in the ankle joint. There are static and dynamic deformities that can create unbalanced ankle joints causing early and often catastrophic failure. Surgeons must recognize the deformities that are present and use sound judgment to balance the ankle joint with procedures before, during, or after total ankle implantation. This article helps clinicians to identify deformity and provides a basic template to consider how to address each challenge...
