Background
Femoral offset refers to the distance between the center of the femoral head and the axis of the femur. This systematic review investigates how changes in femoral offset (increased, decreased, or restored) after hip arthroplasty (hip replacement surgery) affect patient outcomes.
Methods
The review included studies analyzing the impact of femoral offset on patient-reported outcomes (PROs) such as hip function and pain relief. Studies compared the results for patients with different femoral offset adjustments.
Key Findings
Some studies showed better outcomes with increased femoral offset, while others favored restored offset. The best results were typically observed in patients who had their femoral offset restored to normal levels.
Conclusions
Restoring femoral offset during hip arthroplasty appears to lead to better functional outcomes and higher patient satisfaction.
What Does This Mean for Patients
If you are undergoing hip replacement, the surgeon may focus on restoring the natural alignment of your femoral offset to improve your long-term results, including pain relief and mobility.
