The study is aimed at investigating the effects of action observation and motor imagery training in patients undergoing total knee arthroplasty. Fifty participants will be enrolled during hospital admission and randomized into 2 groups (AO+MI and CTRL groups). AO+MI will undergo 12-minute AO+MI intervention for 3 days (preoperative day, first and second postoperartive days), whereas CTRL group will undergo usual care. At baseline, first and third postoperative days, participants will be assessed for mobility, pain, range of motion, quadriceps acrivation failure and patient's bady-pain representation by a blinded operator.

Observation and imagination of functional tasks that will be performed during the postoperative rehabilitation program.
Participants will be educated about the postoperative rehabilitation program
Changes in functional mobility
It will be assessed using the Timed Up and Go test
Time frame: At baseline, at 1 day and 3 days after surgery
Changes in active and passive knee range of motion
It will be assessed using an inertial measurement unit
Time frame: At baseline, at 1 day and 3 days after surgery
Changes in perceived pain
It will be assessed using Numerical Rating Scale (0-10 points), where 0 means no pain and 10 means maximum pain.
Time frame: At baseline and 3 days after surgery
Changes in body pain representation at the level of the knee joint
It will be assessed using the Pain Drawing Body Chart
Time frame: At baseline and 3 days after surgery
Changes in quadriceps activation failure
It will be assessed using the Quadricpes Activation Battery
Time frame: At baseline, at 1 day and 3 days after surgery
