Description
Jennifer Hong and co-authors review partial knee replacement on the outer side of the joint in a 2025 paper. Replacing only the worn lateral compartment can spare the rest of the knee, but the operation stays rare next to its inner-side twin. The outer compartment's bones, loose meniscus, and soft tissue supports move differently, demanding distinct implants and technique.
Older rules limited the surgery to a narrow few patients. Modern evidence widens the gate to younger, heavier patients and those with mild kneecap wear. Fixed-bearing implants guard against dislocation, and robot help sharpens placement. Recent series report over ninety percent of implants surviving ten to fifteen years, with faster recovery and happier patients than full replacement in some measures.
