What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests the Birmingham Hip Resurfacing System for individuals with hip arthritis. The aim is to evaluate the long-term safety and effectiveness of this treatment for non-inflammatory arthritis, like osteoarthritis (where protective cartilage on bone ends wears down), and inflammatory arthritis, such as rheumatoid arthritis (where the immune system attacks the joints). Individuals with hip arthritis considering hip resurfacing surgery might be suitable candidates. Participants must be available for follow-up visits for at least ten years to help researchers assess the treatment's effectiveness. As an unphased trial, this study allows participants to contribute to valuable research that could enhance future arthritis treatments.

Do I have to stop taking my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What prior data suggests that the Birmingham Hip Resurfacing System is safe for arthritis patients?

Research has shown that the Birmingham Hip Resurfacing (BHR) System is generally safe and well-tolerated by patients. Studies have found that the BHR system lasts a long time, with 95.1% of implants functioning well after 15 years, meaning most patients did not need a replacement during that period.

Another study found similar results, indicating that the BHR system is effective and durable, especially for patients with larger hip sizes. While these results are promising, some patients may have different experiences. Overall, the treatment appears to have a strong safety record. ^{1 2 3 4 5}

Why are researchers excited about this trial?

The Birmingham Hip Resurfacing System is unique because, unlike traditional total hip replacements, it preserves more of the patient's natural bone. This system is particularly appealing for younger, active individuals with arthritis who might outlive a conventional hip implant and require a revision surgery later. Researchers are excited about this treatment because it potentially offers better range of motion and stability, allowing patients to maintain a more active lifestyle.

What evidence suggests that the Birmingham Hip Resurfacing System is effective for arthritis?

Research has shown that the Birmingham Hip Resurfacing (BHR) System, which participants in this trial will receive, effectively treats hip arthritis. In the U.S., studies have found that the BHR has a high success rate, with 96% to 99% of patients not needing additional surgery even after 10 years. For men, the BHR system has a 95.1% success rate over 15 years, indicating that most implants function well without issues. Another study reported a similar success rate of about 96.5% after 12 years. These results suggest that the BHR system can provide a long-lasting solution for people with arthritis. ^{2 4 5 6 7}
