2.3. Regular Physical Therapy Intervention
knee flexion, TKA, pain
Regular physical therapy was started on the day after surgery. All participants performed wheelchair practice, ROM exercises, strength training, and walking training according to their pain and general conditions. Our TKA protocol is to perform walking exercises with a walker one week after surgery, with a goal of 90° knee flexion. Two weeks after surgery, patients practice walking with a T-cane with a goal of 100° knee flexion. Three weeks after surgery, the patient will practice climbing up and down steps to be discharged from the hospital. Physical therapy interventions were conducted for 40 min each in the morning and afternoon, for a total of 80 min.
