Summary

This study is checking the long-term safety and performance of two hip implant devices (RingLoc Bipolar Acetabular Cup and Endo II Femoral Head) used in hip replacement surgery. Researchers will follow 116 patients who had their surgery at least eight years ago, tracking complications, revisions, and patient-reported outcomes like pain and mobility. The goal is to confirm these implants continue to work well over time.
