Modular polyethylene failure and attendant revision play an increasing role in hip arthroplasty. In spite of well-fixed, well-aligned components, bearing exchange has a high risk of chronic instability, which may be attributed to the resection of stabilizing soft tissue structures to gain exposure. This creates a difficult situation for the surgeon and an inexplicable one for the patient with a previously well-functioning implant. The senior author modified a technique previously described by Shaw that included an osteotomy of the posterior one third of the greater trochanter and preservation of posterior soft tissues. Thirty-five patients underwent 47 revision procedures utilizing this approach, including 16 modular component and 31 more extensive procedures. There were no dislocations or significant complications and no loss of reduction or nonunion. The approach offers excellent exposure while preserving stabilizing soft tissues.

Multimodal analgesia and anesthesia have become the gold standard in total joint arthroplasty to reduce postoperative pain and opioid consumption and minimize complications associated with opioid use. There are several elements in an effective multimodal protocol, including oral medications, periarticular injection, regional nerve blocks, and spinal and general anesthesia. Many nonopioid medications are often used, such as acetaminophen and NSAIDs.

It is important to provide an overview of the current management of periprosthetic fractures, including techniques for osteosynthesis and revision total hip and knee arthroplasty, as well as special considerations for periprosthetic acetabular fractures, periprosthetic tibial fractures, and interprosthetic femur fractures. In addition, the guiding principles for the management of potential subsequent complications including infection, nonunion, and instability are discussed.

Understanding the risk factors of periprosthetic femur fracture can aid surgeons in the prevention of these injuries. The Vancouver classification provides a reproducible description of the factors that should be considered in the treatment of patients with periprosthetic femur fractures: fracture site, implant stability, and bone stock.

Ankle arthritis is a severely disabling condition. Treatment poses many unique challenges to orthopaedic surgeons because ankle kinematics differs from that seen in the hip or knee joint and the loads transmitted through the ankle are greater during activity. Historically, motion-sacrificing procedures dominated management of ankle arthritis.

Hip arthroplasty in patients with a history of paediatric hip disorders presents a significant challenge for orthopaedic surgeons. These patients are typically younger and have greater functional demands. Therefore, achieving optimal biomechanical conditions is crucial, involving placement of the acetabulum at the ideal centre of rotation and securing a stable femoral component with good offset to preserve abductor muscle function and restore leg length.
