Fractures around the knee in elderly patients: Balancing fixation and arthroplasty approaches, a multicenter experience.

Introduction: In recent years, a discernible shift has occurred in the approach to knee pathologies, specifically in the management of acute fractures. Traditionally, fractures were primarily treated through osteosynthesis, whereas prosthesis replacement was primarily reserved for degenerative issues. Outcomes of this investigation aim to elucidate the potential indications and contraindications for the use of prosthetic interventions in the management of such fractures and to propose a scoring system that can be adopted for the choice between the two different approaches.

The role of femoral head size in metal-on-metal hip arthroplasty: analysis of a cohort of 3813 patients with long term follow-up.

Metal-on-metal (MoM) large headed arthroplasties were suggested to decrease failure rates by means of reduced volumetric wear and enhanced implant stability. However, they caused high rates of revisions due to adverse reaction to metal debris, osteolysis, pseudotumor growth, and other issues. The study aims to present the long-term outcomes of MoM arthroplasties on a large cohort of patients, evaluating the impact of head sizes on survival rate.

Pseudotumor from ceramic-on-ceramic total hip arthroplasty.

Introduction And Importance: Total hip arthroplasty is one of the most performed surgical interventions in the world. Adverse local tissue reactions and pseudotumors are infrequent but dangerous eventualities, which are often related with metal-on-metal or metal-on-polyethylene implants. This study wants to highlight how adverse local tissue reactions and pseudotumors must be taken into consideration during the diagnostic process.
