Evaluation of Noise Induced by Ceramic-ceramic Friction Torques of Total Hip Prostheses With Customized Femoral Stem

Evaluation of Noise Induced by Ceramic-ceramic Friction Torques of Total Hip Prostheses With Customized Femoral Stem

Evaluation of noise induced by ceramic-ceramic friction torques of total hip prostheses with customized femoral stem.

Retrospective and prospective multicentric study.

On a series of patients operated on for more than two years after a total hip arthroplasty that resulted in the implantation of a ceramic-on-ceramic prosthesis with a customized femoral stem:

Primary objective: To assess the frequency of occurrence of joint noise.

Secondary objectives:

• To describe the characteristics of the noise nuisance (date of onset, frequency, intensity, impact...)
• To evaluate the individual and surgical factors associated with the occurrence of noise pollution.

Inclusion Criteria:

• Patient aged 18 years or older, who has been informed of the research
• Patient who has had a fourth generation ceramic/ceramic hip replacement implanted for at least two years as a first-line replacement
• Patient who has had a three-dimensional preoperative examination leading to the design and implantation of a custom femoral stem
• Patient regularly monitored since surgery and for whom all clinical and radiological data are available at the three-month and two-year follow-up visits

Exclusion Criteria:

• Patient operated for revision
• Patient under legal protection, guardianship or curators
• Patient who has indicated his opposition to the use of his medical data (by completing and returning the non-opposition form which will be sent to him)
