Based on expert and patient focus group discussions, a set of evaluation items was established, followed by designing a self-administered questionnaire assessing importance, frequency, and difficulty. From February to December 2024, TKA patients at 1\u202fyear post-surgery and age-matched healthy controls were recruited at Honghui Hospital, Xi\u2019an, China.

The study included 713 TKA patients and 675 age-matched healthy controls, and 14 high-frequency activities were identified based on importance ratings. No significant functional differences were observed between TKA patients and controls in individuals under 65\u202fyears. In the 65\u201375-year group, only females showed decreased performance in picking up items from the ground (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.001).
