"All participants in experimental group were adviced to see periopertive knee photograph before rehabilitation everyday.~Postoperative knee ROM were recorded at day 3, 6 week, 3 month and 6 month. Flexion and extension angle were measured with long arm goniometer.~The outcome assessors were blinded to treatment groups."

"All participants in active comparator group didn't receive perioperative knee photograph.~Postoperative knee ROM were recorded at day 3, 6 week, 3 month and 6 month. Flexion and extension angle were measured with long arm goniometer.~The outcome assessors were blinded to treatment groups."
