UKA: Definition, Uses, and Clinical Overview
UKA stands for **unicompartmental knee arthroplasty**, often called a **partial knee replacement**. It replaces only the **damaged compartment** of the knee rather than the entire joint. UKA is commonly used for **localized knee arthritis** when the rest of the knee remains relatively preserved. It is performed by orthopedic surgeons and is part of standard knee reconstruction options.
