Identifying patient subgroups with different trends of patient-reported outcomes (PROMs) after elective knee arthroplasty.

The results suggest three main PROMs trajectories in patients undergoing elective TKA. Most patients reported improved quality of life and joint functioning at 6 months, which then stabilized. However, other subgroups showed more varied trajectories. Further research is needed to confirm these findings and to explore the potential clinical implications of these results.
