ClinConnect Summary

This clinical trial is studying how different surgical approaches for total hip replacement may affect a condition called leg dysmetria, which is when the legs are not the same length after surgery. The researchers want to see if using special navigation technology during surgery helps position the hip joint correctly and safely, compared to traditional methods. They will also look at how long the surgery takes and how accurately the surgery is planned.

To be eligible for this trial, participants should be between 50 and 80 years old and have significant pain from hip osteoarthritis, which is a type of joint disease that causes pain and stiffness. Participants will be monitored for a year after their surgery to evaluate how well the procedure worked. It’s important to note that certain health conditions, like uncontrolled diabetes or previous hip surgeries, may exclude individuals from participating. Overall, this study aims to improve surgical outcomes for people undergoing hip replacement surgery.
