Researchers want to understand what happens to your spine and posture after you have hip or knee replacement surgery. Many older adults have arthritis in both their joints and spine, but doctors don't yet know how replacing a hip or knee affects the way your spine aligns and how your body balances itself when standing.
Hip and knee replacements are very successful at relieving pain, but doctors rarely study how these surgeries might change your spine alignment and posture. This study aims to fill that gap by tracking whether your body balance improves or changes after surgery.

You will have measurements and imaging of your spine and body alignment taken before your surgery and at least once during your follow-up year. These measurements help doctors track whether your posture and spinal alignment change after your hip or knee replacement. The study simply observes and documents these changes — you are not receiving any new medication or experimental treatment.
