ClinConnect Summary

This clinical trial is studying a specific hip problem called a cam deformity, which is an abnormal shape of the hip joint that can cause pain and may lead to osteoarthritis (OA) if not treated. The goal is to understand how surgical treatment, which involves removing the cam deformity, can relieve pain and improve hip function in young adults who have been experiencing hip pain for more than six months. Researchers want to see how this surgery can help prevent further damage to the joint and reduce the chances of developing OA in the future.

To participate in the trial, individuals must be at least 18 years old and have hip pain for over six months, but they should not have any arthritis or significant joint deformities. Participants will undergo surgery and will need to attend follow-up visits to assess their recovery and improvements. It's important to note that certain conditions, such as recent joint injuries or specific health issues, may prevent someone from joining the study. This trial is currently recruiting participants, and anyone interested should discuss it with their healthcare provider to see if they qualify.
