Is robotic hip replacement worth the extra cost? Compare component positioning accuracy, recovery differences, and long-term outcomes.
In traditional (manual) hip replacement, the surgeon uses mechanical guides, templates, and their own expertise to prepare the bone and position implant components. This technique has been refined over 50+ years with millions of successful surgeries worldwide. Outcomes: 95%+ satisfaction rate, 25-30 year implant survival. The vast majority of hip replacements performed globally still use manual technique. Surgeon skill and experience remain the most important factors in outcomes.
Robotic systems (Mako by Stryker, ROSA by Zimmer Biomet, Velys by DePuy) use pre-operative CT scans to create a 3D model of the patient's hip anatomy. The surgeon plans optimal component positioning on a computer before surgery, then uses a robotic arm that provides real-time feedback and boundaries during bone preparation. The surgeon controls the process at all times — the robot provides guidance, not autonomous action.
Robotic assistance improves the consistency of component positioning, which may reduce the risk of dislocation and accelerated wear. Early studies show fewer outliers in cup placement and more accurate leg length restoration. However, both techniques achieve 95%+ satisfaction. Choose your surgeon based on experience and volume first — a high-volume manual surgeon will likely outperform a low-volume robotic surgeon. If your preferred surgeon offers robotic assistance, it is a reasonable advantage.
