Follow-up Study of Prevision Hip Stem Implants Comparing Different Variants in Revision Hip Surgery

What this Trial Is About

Researchers are evaluating the safety and performance of the Prevision hip stem in patients undergoing revision hip arthroplasty or treatment for periprosthetic hip fractures. This observational post-market clinical follow-up study aims to confirm that the functional outcome of the Prevision hip stem is not inferior to previous implant generations after two years. The study also compares patient outcomes across different implant variants within the Prevision family. The Prevision hip implant system includes both modular and monobloc cementless and cemented hip stems that can be implanted using mostly the same instruments, allowing easy switching between variants. Modular stems feature components connected with a specific conical connection and may include locking screws for added bone fixation. All implant variants are available at study sites, and switching between them during the study is encouraged to assess differences in patient outcomes. Participants will be followed up with assessments including the functional outcome of hip revision surgery after two years, as well as secondary measures like implant survival, quality of life, complications, patient satisfaction, pain scores, and radiologic evaluations at 2 and 5 years. Patients must attend follow-up visits for ongoing monitoring, with the total study duration extending up to five years to capture long-term outcomes and safety.
