Design outcomes

Primary

Measure	Time frame
Improvement of early functional mobility assessed by a modified telephone-based 6-minute walk test at 6 weeks postoperatively. This parameter is evaluated preoperatively, at discharge (day 5–7), and during telephone follow-ups at weeks 6, 12, 26 and 52. Data are collected through standardized structured telephone interviews assessing walking distance, walking time, and joint function. Pain intensity (NRS 0–10 at rest and during movement) is recorded simultaneously as a supportive primary parameter.	—

Secondary

Measure	Time frame
Patient satisfaction assessed through the modified Knee Society Score (m-KSS) and the Forgotten Joint Score (FJS-12). Health-related quality of life measured by the telephone versions of SF-12 and EQ-5D at all follow-ups (weeks 6, 12, 26 and 52). Functional daily living abilities assessed by the modified Barthel Index and structured telephone interviews. Analgesic consumption recorded via standardized telephone interview. Postoperative complications (Clavien-Dindo classification), revision surgeries and length of hospital stay.	—
