Postrange of motion (°)	120.0 [105.0–125.0]	115.0 [100.0–120.0]	0.295
Post‐FTA (°)	176.5 [175.5–176.8]	176.0 [175.0–176.0]	0.052

Post‐WBLR (%)	50.0 [49.0–50.0]	49.3 [47.6–50.3]	0.610
KOOS pain (points)	88.9 [86.1–92.4]	77.8 [77.0–88.9]	0.162
KOOS symptoms (points)	91.1 [85.7–96.4]	85.7 [75.0–90.0]	0.206
KOOS ADL (points)	86.8 [82.7–87.9]	70.7 [67.6–89.0]	0.139
KOOS sports/rec. (points)	55.0 [25.0–75.0]	50.0 [35.0–56.3]	0.933

Note: Data are presented as medians [interquartile ranges]. Comparisons between MB and FB were performed using the Mann–Whitney U test. A p‐value < 0.05 was considered significant.
