She underwent robotic arm-assisted total knee arthroplasty (RA-TKA). Although the saw blade did not require replacement during surgery, a fracture associated with the tibial checkpoint occurred. The error of implant placement from the intraoperative plan was within 3.4\u00b0. After 1 year, the Forgotten Joint Score was 77, and she was independent in activities of daily living.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>RA-TKA allows safe and precise bone resection, achieving appropriate alignment even in osteopetrosis.
