Evaluating the performance of a modular hip stem in revision hip surgeries
Official title: Medacta M-Vizion™ Macroscopic Radiographic Study, Multi-center, Post-Market Outcomes Study
Run by Medacta USA · NCT05721859 · Data updated 2026-11-12
This study is testing if a new modular hip stem can stay stable during revision hip surgeries for patients and if it will move less than 5mm over two years.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients aged 21 to 80 who require a revision total hip replacement and are receiving the M-Vizion femoral component.
✕Probably not a fit
Patients with neuromuscular deficiencies or systemic disorders that affect bone health may not benefit from this study.

What this trial studies
This observational study aims to assess the performance of the M-Vizion modular stem in patients undergoing revision hip arthroplasty. It focuses on measuring the subsidence of the femoral stem within the canal over a two-year period. Participants will be monitored to ensure they meet the inclusion criteria and comply with the study protocol. The study seeks to determine if the M-Vizion stem will result in less than 5mm of subsidence, indicating effective performance.
Why it matters
Potential benefit: If successful, this study could lead to improved outcomes and stability for patients undergoing revision hip arthroplasty.
How similar studies have gone: Other studies have shown promising results with similar modular hip stem approaches, indicating potential for success.

Inclusion Criteria: * Must be able to read, understand, and provide written informed consent on the Institutional Review Board (IRB) approved Informed Consent Form (ICF). * Ability to understand and provide written authorization for use and disclosure of personal health information. * Subjects who are able and willing to comply with the study protocol and follow-up visits. * Patients requiring a revision total hip replacement. * Subjects undergoing revision THA who will receive an M-Vizion femoral component according to the indications for use. * Male and female patients ages 21 - 80 years of age at the time of surgery. Exclusion Criteria: * Patients with neuromuscular or neurosensory deficiency, which would limit the ability to assess the performance of the device. * Patients with a systemic or metabolic disorder leading to progressive bone deterioration. * Patients bone stock is compromised by disease or infection, which could possibly prevent adequate support and/or fixation to the prosthesis. * Patients with an active or suspected latent infection in or about the hip joint. * Patients that are incarcerated.
