"Ultra sound (US):~Pulsed ultrasonic waves were delivered at a 1 MHz frequency and at an intensity of 1 watt/ cm2 via a transducer with a diameter of 5 cm and effective radiating area of 3.5 to 5cm² for 9.5 min (Medserve, England) (Huang et al., 2001). Patients were positioned in a supine position with the affected knee flexed at 90° and the sound head was held stationary over the tibiofemoral joint medial to the patellar tendon to enhance energy penetration into the joint space (White et al., 2007).~Exercise program:~The subjects were treated with a group-exercise program composed of a range of motion of all lower limb and 45 min strengthening exercises with 5 min stretching exercises of lower limb muscles 3 times per week under the supervision of the same physiatrist (Fitzgerald and Oatis"
