  • Articulating components should minimise the generation of wear particles in order to optimize long-term survival of the prosthesis.

  • A good understanding of tribological properties helps the orthopaedic surgeon to choose the most suitable bearing for each individual patient.

  • Conventional and highly cross-linked polyethylene articulating either with metal or ceramic, ceramic-on-ceramic and metal-on-metal are the most commonly used bearing combinations.

  • All combinations of bearing surface have their advantages and disadvantages. An appraisal of the individual patient’s objectives should be part of the assessment of the best bearing surface.

Introduction Patients with untreated developmental dysplasia of the hip (DDH) may eventually develop secondary osteoarthritis, beginning in early adulthood. Arthroplasty is the main treatment of choice. In some countries, DDH is the main cause

. 27 Evidence for a threshold of > 60° is mounting due to previously published data, showing that an alpha angle exceeding 60° is associated with clinical symptoms and the development of incident osteoarthritis. 28 , 29 During flexion, internal

Background The interest in treating hip pathologies, such as developmental dysplasia of the hip (DDH), femoroacetabular impingement (FAI) and labral tears in patients without radiographic signs of osteoarthritis (OA), has rapidly increased

Introduction Total hip arthroplasty (THA) is a common procedure for primary osteoarthritis but increasing numbers are also being performed for other pathologies such as secondary arthritis, inflammatory arthropathies and trauma. Estimates

Introduction The surgical treatment of symptomatic end-stage hip osteoarthritis has evolved over the last three hundred years from rudimentary excision surgery to modern robotic total hip arthroplasty (THA). 1 Prior to the advent of
