The modified-KLICC score: a novel tool to predict outcomes following debridement, antibiotics, and implant retention after early acute periprosthetic hip infection Open
Aims Two preoperative risk models have been designed to predict debridement, antibiotics, and implant retention (DAIR) failure: KLICC and CRIME-80 scores. However, external validation of both scores is scarce. We aimed to validate these sc…

Fracture of a triple-polished tapered cemented femoral stem at the Morse taper after metal-on-metal primary total hip arthroplasty Open
Total hip arthroplasty, one of the most successful orthopaedic procedures, is influenced by several variables. Corrosion at the modular junction is known as trunnionosis. Despite being reported infrequently, corrosion between the femoral h…

Gait instability may indicate liner failure in patients with total hip arthroplasty. A report of three cases Open
Total hip arthroplasty is one of the most common and successful orthopaedic procedures performed worldwide. Uncemented modular acetabular components and highly cross-linked polyethylene liners are the implants of choice for most arthroplas…

Bilateral Intracapsular Hip Fracture in a Patient With Low Functional Demand Treated With a One-stage Bilateral Hemiarthroplasties. A Case Report and Literature Review. Open
Bilateral femoral neck fracture is a rare injury. While they may be of traumatic origin, they are generally associated with some underlying condition that predisposes to this pathology, such as neurological disorders or bone metabolism dis…

Preliminary Outcomes of the Cementless UNITED Hip System for primary Total Hip Arthroplasty at a Minimum Two-year Follow-up Open
Introduction: This study aimed to report the initial results of the cementless UNITED hip system in primary total hip arthroplasty (THA) with a minimum follow-up of 2 years. Methods We retrospectively studied a consecutive series of 203 ce…
