ClinConnect Summary

This clinical trial is designed to compare different surgical techniques for hip replacement in patients with a condition called coxarthrosis, which is a form of arthritis affecting the hip joint. The study will look at how well these surgeries restore normal hip movement and function by measuring certain parameters before and after the procedures. Participants will undergo a special type of imaging called EOS radiography before their surgery and then again at three months and one year after surgery, along with a CT scan after three months.

To be eligible for this study, participants must be at least 18 years old and scheduled for one of the three types of hip surgeries: total hip replacement, Minihip, or hip resurfacing. They should not have severe arthritis in the other hip, and must be willing to follow the study requirements. Participants will be asked to complete questionnaires and undergo clinical examinations at various points during the study. The trial is currently not recruiting, but it aims to provide valuable insights into how different surgical approaches can affect recovery and hip function.
