Introduction Distal femoral replacement (DFR) is a potential treatment option following periprosthetic fracture (PPF) of a total knee arthroplasty (TKA). However, there is limited literature regarding implant survivorship and complication rates. The aim of this study was to examine patient demographics and trends in usage, implant survivorship and...

Background Minocycline black bone disease is a rare finding that can cause concern when unexpectedly encountered during routine arthroplasty. Prolonged minocycline use can cause selective staining of subchondral bone, whilst peri-articular soft tissue and cartilage appear uninvolved. Methods A systematic review according to PRISMA guidelines was p...

Case: A 57-year-old man presented with tricompartmental left knee osteoarthritis, as well as proximal tibiofibular joint arthritis and a ganglion cyst. He underwent simultaneous total knee arthroplasty and proximal tibiofibular joint arthrodesis, with an excellent outcome. Conclusion: Proximal tibiofibular joint arthritis is uncommon and may be...

Total knee arthroplasty (TKA) is associated with significant postoperative pain. The population receiving TKA is generally elderly and often have multiple comorbidities that can present a challenge to postoperative management. Safe and effective multimodal pain management has led to improved outcomes while minimizing complications and side effects....

Case: A 9-year-old boy sustained a right distal clavicle physeal separation with superior and posterior displacement through the periosteum. He was treated surgically with open reduction, Kirschner wire fixation, and periosteal repair and had an excellent outcome. Conclusion: Distal clavicle fractures are rare in children, and acromioclavicular...

Background: Paget's disease of bone (PDB) is a common destructive condition of bone that affects 1-2% of the population, most typically those over the age of 55 years. It is usually asymptomatic. Objective: The aim of this article is to describe the clinical presentation, diagnosis and management of patients with PDB. Discussion: Most cases of...

Background: Osteoarthritis of the hip and knee is a common cause of pain and reduced mobility. Arthroplasty reliably improves quality of life for most patients when non-operative measures have failed. However, hip and knee arthroplasties are major operations that carry significant risks, including the need for revision surgery. Objective: The pu...

The specialty of orthopaedics includes management of musculoskeletal pathology of the upper limbs, spine and lower limbs across the lifespan, from the very young to the very old.

Objective To assess the intra- and inter-observer reliability of three commonly referenced radiographic classification systems for knee osteoarthritis in a cohort of arthroplasty candidates.Materials and methodsPre-operative radiographs of 112 patients who subsequently underwent primary total knee arthroplasty were evaluated by four independent obs...

Background: Anterior cruciate ligament (ACL) reconstruction is a common orthopaedic procedure. We developed a novel, low dose computed tomography (LDCT) protocol to assess tunnel position post-operatively. The effective radiation dose of this protocol is < 0.5millisieverts (mSv), which is significantly less than the 2 mSv dose for a conventional C...

Background: Joint replacement surgery is a highly effective treatment option for patients with severe osteoarthritis (OA) of the hip and knee when other treatments have failed. Unfortunately, as a result of the COVID-19 pandemic, a temporary suspension of non-urgent elective surgery was implemented. Thousands of patients currently awaiting hip and...

Background Major lower limb amputation is occasionally required in the management of end-stage pathology where other treatment options have failed. The primary aim of this study was to determine the 30-day and 1-year mortality rates of patients undergoing nontraumatic major lower limb amputation. Secondary aims were to investigate risk factors for...
