n: number of patients who participated varied depending on patients’ ability to cooperate. Knee extension and knee flexion: significant difference between the groups at 27 h.

Oxford knee score: 12 (the best possible) to 60 (the worst possible).

Preop. score vs. 14 days postop. scores: p = 0.05 (group A); p < 0.001 (group P).

Preop. score vs. 3-month and 6-month postop. scores: p = 0.001 (group A); p < 0.001 (groupP).

EQ-5D health outcome: 1 = perfect health; 0 = poor health; and negative values = very poor health outcome.

Preop. values vs. 6-month values: p = 0.001 (group A); p < 0.001 (group P).
