Rehabilitation after total knee arthroplasty (TKA) should consider control of postoperative pain and swelling, protection of the healing graft, restoration of full range of motion symmetric to the contralateral knee, strengthening of the muscles that stabilize the knee, hip, and trunk, enhancing neuromuscular control, and a gradual progression to functional activities that are required for return to the normal daily life. The effects of concomitant injuries and surgical procedures must also be considered in planning an individualized rehabilitation program. However, it is still unclear regarding the optimal exercise prescription after TKA. In the current study, the investigators plan to develop an exercise protocol and evaluate the result in a multidisciplinary approach, i.e. bone mineral density assessment. The exercise prescription consisted of cyclic exercise, aerobic exercise and resistant training exercise for first, second and third year, respectively. Cyclic exercise is advantaged safety and effectiveness of hydraulic resistance equipment, as well as the exercise can be quantitatively determined. Aerobic exercise is privileged by the cardiopulmonary endurance improvement, along with muscle strengthening in the associated muscle groups. Resistance exercise is specified for the indicated muscle groups, especially knee extensors, flexors, ankle plantar flexor and dorsi flexor in TKA reconstructed patients. The investigators hypothesis that using this cyclic exercise process can improve the body composition, muscle strength, bone mass density, level of oxidative damage indicators, gait performance, quality of life, knee joint range of motion, function of cardiopulmonary and fitness. This project will establish the scientific basis for rehabilitation protocol involving knee surgery.

| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline bone mineral density | Bone mineral density measurement is measured by dual-energy x-ray absorptiometry (DXA). Measurements are made over the lumbar spine and over the upper part of the hip and the measurement is assessed at pre-operation, three month, six month and nine month after operation, and twelve-month follow-up. | pre-operation; three month ; six month and nine month after operation; twelve-month follow-up |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline lower extremity muscle strength | Lower extremity muscle strength, including extension and flexion of the hip, knee and ankle were tested by the HUMAC NORM system (CSMi, Stoughton, MA) with the eccentric/concentric contraction mode at an angular velocity of 60 degrees/s.Isokinetic tests were performed five times for each participant, and each test was separated by a rest period of 3 min. The participants are assessed at pre-operation, three month, six month and nine month after operation, and twelve-month follow-up and received verbal encouragement during the exertion of peak torque. |

| Motion analysis | Gait analysis by VICON three-dimensional, 8-camera motion capture system.The outcome measurement is assessed at pre-operation, three month, six month and nine month after operation, and twelve-month follow-up. | pre-operation; three month ; six month and nine month after operation; twelve-month follow-up |
| Change from baseline SF-36 questionnaire assessment | SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower score the more disability. The higher the score the less disability. Eight sections including physical function, role limitation due to physical problems, bodily pain, general health, vitality, social functioning, role limitation due to emotional problems, and mental health. Additionally, the eight health domains can be used to provide a physical component summary and mental component summary score. The outcome measurement is assessed at pre-operation, three month, six month and nine month after operation, and twelve-month follow-up. | pre-operation; three month ; six month and nine month after operation; twelve-month follow-up |
| Change from baseline KOOS questionnaire assessment | KOOS contains 5 subscales with a total of 42 items: 1) pain, 2) other symptoms, 3) function in daily living (ADL), 4) function in sport and recreation and 5) knee-related quality of life. Each question receives a score from 0 to 4 and the scores are transformed to a 0-100 score (0, extreme symptoms, 100, no symptoms). The User's Guide, is available from www.koos.nu. The outcome measurement is assessed at pre-operation, three month, six month and nine month after operation, and twelve-month follow-up. | pre-operation; three month ; six month and nine month after operation; twelve-month follow-up |
