It is performed when the knee has deformity, instability, bone loss, or other challenges that require additional planning and specialized implants. It is commonly used for advanced arthritis or post-traumatic knee damage when standard techniques may not provide reliable alignment or stability. Although it is \u201cprimary\u201d (not a revision), it can use tools and implant features that overlap with revision surgery."}
