Case: We present a case of late onset, bearing wear-induced failure of locking mechanism, resulting in bearing dislocation and rapidly progressive severe metallosis in a medial fixed-bearing (FB) unicompartmental knee arthroplasty (UKA).
Conclusion: Bearing dislocation is a rare complication of chronic wear in FB UKA, and early recognition is essential to prevent metallic component articulation-induced metallosis and catastrophic failure.

Intraprosthetic Dislocation Following Dual Mobility Total Hip Arthroplasty: A Retrieval Analysis Study.
Arthroplast Today
February 2025
Department of Orthopaedic Surgery, Fiona Stanley Fremantle Hospitals Group, Murdoch, Western Australia, Australia.
Background: Dual mobility (DM) implants in total hip arthroplasty provide excellent range of motion with low dislocation rates. A complication of this design is intraprosthetic dislocation (IPD), where the polyethylene (PE) liner dissociates from the femoral head. In older designs, IPD occurred due to a small head size and late PE wear with head-capture-mechanism failure.

Background: Dislocation remains a common complication following total hip arthroplasty (THA). Previous literature has shown that the femoral head-to-neck ratio is essential in hip motion, function, and stability. While large femoral heads and dual mobility bearings have been developed to improve stability, it remains unknown if the ratio between femoral head size to acetabular cup size also plays a role in stability.

Introduction: Bony and ligamentous ankle injuries are some of the most commonly treated injuries by orthopedic surgeons. Open ligamentous ankle injuries without an associated fracture or dislocation are rare and to our knowledge have only sparsely been described in the literature. We present a case and successful treatment of an open lateral ankle injury with capsular rupture and ligamentous damage without fracture or dislocation in a 22-year-old female.

Department of Orthopedic Surgery, Yamaguchi University Graduate School of Medicine, Ube, JPN.
Background: Two-stage revision is known as the gold-standard method for knee prosthetic joint infection (PJI), but the most suitable treatment method remains controversial. Typically, weight-bearing is restricted during the interval between the stages. The aim of this study was to evaluate the clinical outcomes of unrestricted weight bearing with cement spacers fabricated using the Knee Articulating Spacer Mold (KASM®; Ortho Development Corporation, Draper, UT, USA) for knee PJI.

Introduction: Mobile-bearing (MB) inserts, designed to minimize aseptic loosening and to reduce contact stresses leading to polyethylene wear, are an alternative to fixed-bearing (FB) inserts. Most studies have shown no significant difference between MB and FB constructs, and there is limited long-term data comparing the two constructs [1,2,3,4]. The purpose of this study was to report the outcomes of a randomized controlled trial comparing MB versus FB inserts on patients with minimum 20-year follow-up.
