Polymotion Hip Resurfacing System for Hip Osteoarthritis and Dysplasia

This study is looking at the safety and effectiveness of the Polymotion Hip Resurfacing (PHR) System. This system is a type of hip surgery that aims to be an alternative to a total hip replacement, especially for younger, more active individuals. It involves replacing only the surface of the hip joint, rather than removing the entire ball and socket. Researchers will compare the PHR System to traditional total hip replacement surgery. You might be able to join if you are between 21 and 65 years old and need hip resurfacing due to non-inflammatory arthritis (like osteoarthritis) or mild hip dysplasia. The main goal is to see how safe and effective the PHR System is after 24 months. The current status of this study is unclear.

Study design
This is an interventional study planning to enroll 238 participants. It compares the Polymotion Hip Resurfacing System to total hip arthroplasty.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
The primary goal of the study will be measured at 24 months after the intervention.

What this trial measures

  • The primary objective of this study is to evaluate the safety and clinical effectiveness of the Polymotion Hip Resurfacing System.24 months

    The proportion of Polymotion subjects achieving Month-24 composite clinical success (CCS) will be compared to a propensity-score matched total hip arthroplasty control group collected from Rush University Medical Center, with the goal of demonstrating non-inferiority. Composite clinical success will be analyzed via Harris Hip Scores measuring pain, activity, and function, absence of device subsidence, progressive radiolucencies, osteolysis or migration through radiographic assessment, and the absence of serious safety events (secondary surgical interventions for the index hip or serious device-related adverse events).
