Description
Anne Ruth van Meijeren and four co-authors compare two ways of aligning a replacement knee in a 2026 study. Up to ten percent of knee replacement patients end up dissatisfied. Robotic surgery lets surgeons align the new joint to the patient's anatomy rather than a mechanical template, and ligament balance is thought to drive satisfaction.
In two hundred patients, the robot simulated both alignment plans inside the same knee during the operation, measuring how far each side of the joint opened under stress. The personalized plan balanced ligaments far more often across knee shapes. In one shape, balanced knees jumped from about eight percent under the template plan to about eighty-nine percent under the personalized one. The authors treat native knee shape as a guide, noting the analysis is exploratory. Balance in the operating room still has to prove itself in long-term comfort.
