Periprosthetic fractures after hip replacement

Achieving the best outcome—pitfalls to avoid and practices to adhere to

Surgical treatment of periprosthetic femoral fractures (PPFF) is a challenging task. Understanding individual patients’ injury histories and needs, correct diagnosis, presurgical preparation, and optimal implant selection are all part of the equation leading to good outcomes. Best patient outcomes can be achieved through a patient-centered approach and a close look at the latest findings in this very dynamic research area.

Unicompartmental knee arthroplasty (UKA)

Treating single compartment knee osteoarthritis—options and observations

Unicompartmental knee arthroplasties (UKAs), also known as partial knee arthroplasties, can achieve outcomes and survivorship comparable to those of total knee arthroplasties (TKAs) and high tibial osteotomies (HTOs). Indications and counterindications, procedure volume considerations, and thresholds for revision are constantly being reassessed, based on increased data on reported patient outcomes. Proper patient selection remains critical to achieve good results.

Computer-assisted surgery (CAS)

The evolution of CAS and what the future might hold for us

Robotic surgery, computer-assisted navigation, and personalized instrumentation and implants are no longer science fiction: Many institutions already use some of these technologies for precision and planning support. Computers can calculate basic operations 10 million times faster than the human brain. Will they eventually replace orthopedic surgeons in the operating room?

Periprosthetic joint infection (PJI)

The growing risk of PJI and how to manage it

Did you know that dragonflies have a nanoscale surface pattern on their wings that prevents microorganisms from attaching to them? Researchers are studying this phenomenon, together with other innovative avenues, to advance the options available in the prevention, diagnosis, and treatment of periprosthetic joint infection (PJI). Here we consider the nuances and difficulties that surgeons encounter when dealing with deep infection in their arthroplasty patients. Expert surgeons, Olivier Borens and Andrej Trampuz, provide valuable commentary and insights about the strategies available to address PJI.

Positioning of the acetabular component

Acetabular cup positioning—a patient-specific approach

Let us take a close look at the multi-factorial considerations in accurate acetabular cup placement during total hip arthroplasty (THA). This is a challenging aspect of the procedure as it requires knowledge and visualization of anatomy and component position in three dimensions, amongst other things. Understanding each patient’s unique kinematics and structure, screening for spinal and/or other comorbidities, and careful pre-operative planning all play an important part in providing a personalized procedure and positive outcome for patients.
