Observational and Prospective Multicenter Study to Evaluate the Long-term (10 Years) Performance and Safety (10 Years) of ATF Implants and Lapé Médical Devices Implanted During Total Hip Arthroplasty or Hemiarthroplasty.

Study start date: June 7, 2021

Inclusion Criteria: * Male or female indicated for hip replacement surgery with hip prosthesis manufactured by ATF Implants and/or Lapé médical; There are different indications for hip replacement surgery. The main ones are listed below: * Dysplasia * Primary Coxarthrosis * Secondary Coxarthrosis * Perthes disease * Epiphysiolysis * Ankylosing spondylitis * Trochanteric bursitis * Arthritis * Degenerative arthritis * Post-traumatic arthritis * Rheumatoid arthritis * Femoral neck fracture * Osteonecrosis * Revision Depending on the specificities of the devices (size, absence/presence of a coating, material), indications may vary. This information can be found in the instruction for use. It is the surgeon's responsibility to select the most appropriate prosthesis for a given patient according to the patient's medical records and the instruction for use in force at the time of the procedure accompanying the medical device. Exclusion Criteria: * There are various contraindications for hip arthroplasty. The main ones are listed below: * An acute or chronic, local or systemic infection * Severe muscular, neurological or vascular deficiency compromising the affected extremity * A bone defect or insufficient bone quality that may compromise the stability of the implant * Any concomitant disease (dysplastic coxarthrosis with extreme coxa valga, short neck and severe varus) that may affect the function of the implant * Sensitivity to the material (allergy) Depending on the specificities of the devices (size, absence/presence of a coating, material), contraindications may vary. This information can be found in the instruction for use of the devices.
