n: number of patients who participated varied depending on patients' ability to cooperate.

TUG test: Timed up and go test.

^a na: not applicable. No statistical calculations were done due to the small number of patients in each group.

^b Patient satisfaction: Excellent = 4, good = 3, inadequate = 2, poor = 1. In group A, 20/23 scored 3–4 as compared to 12/20 in group P 7 days postoperatively.

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

EQ-5D health outcome: 1 = perfect health; 0 = poor health.
