It is used in **total knee arthroplasty (knee replacement)** to preserve the **posterior cruciate ligament (PCL)**. The goal is to replace worn joint surfaces while keeping part of the knee\u2019s native ligament system. You will see CR knee discussed in orthopedic surgery notes, implant catalogs, and knee replacement planning."}
