Article Abstract
Metal-on-metal is one potential bearing option for total hip arthroplasty (THA). Proponents of the bearing have suggested that if the tribology is optimal, volumetric wear may occur at levels at least one order of magnitude lower than metal-on-polyethylene bearings. We present a unique postmortem case of a well fixed, metal-on-metal, McKee-Farrar total hip arthroplasty implanted 30 years previously that was clinically asymptomatic in life. Clinical and radiological examination is supplemented by tribological examination of the bearing and histopathological examination of the cement-bone interface.

Purpose: Robotic-assisted total knee arthroplasty (RA-TKA), which is increasingly used to improve surgical precision, can face adoption difficulties due to a learning curve marked by longer operating times. The aim of this study was to evaluate the learning curve associated with the VELYS™ robot in five surgeons from the same centre with different annual arthroplasty volumes using navigated assistance with personalised alignment. The primary aim was to assess the learning curve for each surgeon.

Purpose: The factors influencing patient-reported outcome measures (PROMs) in individuals with developmental dysplasia of the hip (DDH) remain poorly understood. The aim of this study was to determine the differences in hip-related PROMs in both borderline and true hip dysplasia.
Methods: A total of 245 patients with symptomatic DDH were enrolled.

Background: Total hip arthroplasty (THA) is a common intervention for severe hip disorders. However, postoperative instability and dislocation continue to present significant challenges. To address these issues, dual mobility (DM) cups and large femoral heads (LFH) have been employed, each offering unique biomechanical benefits.

Background: Acetabular reconstruction is often challenging in revision hip arthroplasty, especially in the face of moderate to severe acetabular bone deficiency. In some severe bone defects, double-metal tantalum cups can improve the contact area between bone and implants, increase the surface area for bone ingrowth, and better restore the anatomical position of the acetabulum. Furthermore, with a good press-fit, the auxiliary screw has a minimal effect on acetabular cup stability.

Background: Total hip arthroplasty (THA) has theoretical advantages and disadvantages over hemiarthroplasty for femoral neck fractures. Numerous studies have suggested equivalent reoperation rates between the procedures. The purpose of this study was to use the reverse fragility index (RFI) to evaluate the statistical robustness of randomized controlled trials (RCTs) reporting nonsignificant differences in reoperation rates between hip hemiarthroplasty and THA for femoral neck fractures.
