Postoperative range of motion, according to the difference between pre- and post-TKA based on posterior condylar offset (PCO) and posterior condylar offset ratio (PCOR). Postoperative ROM did not differ regardless of PCO and PCOR differences in both the AR (p = 0.935 and 0.688) and the PR group (p = 0.940 and 0.552)
