Traumatic Arthritis

The purpose of this research is to gather clinical and radiographic (X-ray) information about EMPHASYS™ acetabular shell (also called a hip 'cup') placement in total hip replacement surgery using a non-invasive surgical navigation system called VELYS™ hip navigation system with CUPTIMIZE™ Advanced Hip-Spine Analysis software. Data collected in this study will be compared with data collected from implantations using different cup positioning instrumentation and techniques to assess performance.

The main objective of the study is to evaluate the safety, performance and clinical benefits of the Persona implant and its instrumentation in primary total knee arthroplasty

This is a Post-Marketing Surveillance of SMS femoral stem prosthesis.

The general objective of this study is to assess the performance and safety of the KeriFlex® silicone joint implant and its associated instruments, used in accordance with the labeling and instructions in force. The performance and safety of the KeriFlex® joint implant will be established in the short and long term with regard to the life cycle of the implant.

The goal of this randomized, controlled, monocentric, single-blind, 2-arm, feasibility clinical investigation is to evaluate the safety of MectaShield hydrogel coating and to capture its preliminary clinical performance in the prevention of early peri-prosthetic joint infection (PJI) in patients undergoing cementless revision hip arthroplasty. The main questions it aims to answer are: * demonstrate that the hydrogel coating MectaShield does not interfere with primary stability; * evaluate clinical and functional outcomes, the rate of PJI and possible adverse events. Participants will undergo cementless revision hip arthroplasty; during surgery MectaShield hydrogel coating is applied on orthopaedic implants' surfaces (femoral stem and, if revised, acetabular cup) as a protective barrier for the prevention of bacterial adhesion. Surgery and follow-up are completed as per local standard practice. Stability will be assessed radiologically, while functional outcomes and PJI will be monitored by HOOS-PS, ASESPIS scores and according to the consensus document presented by European Society of Radiology (ESRa), the European Association of Nuclear Medicine (EANM), the European Bone and Joint Infection Society (EBJIS), and the European Society of Clinical Microbiology and Infectious Diseases (ESCMID). Researchers will compare the results of the treatment group with those from a control group receiving cementless revision hip arthroplasty without the application of MectaShiled hydrogel coating.

The primary objective of this study is to obtain long-term implant survivorship (out to 10 years) and to assess clinical, patient-reported outcome measures, and radiographic data for the commercially available Physica system. For ancillary arm, from baseline to 5-year follow-up.

The purpose of this study is to evaluate the safety and effectiveness of the EcoFit Hip with implacross E polyethylene for total hip replacement surgery.
