Randomization will performed by the four-block technique. Patient and assessor who will gather the data will blinded about the type of treatment modality (Double-Blinded). We will use a randomization table and will divide all the patients into four blocks. The patients will allocate to three groups based on the treatment including Light, LLLT, and control groups, Blinding description: Randomization will performed by the four-block technique. Patient and assessor who will gather the data will blinded about the type of treatment modality (Double-Blinded). The patient and investigator will blinded about type of Intervention. N/A Knee osteoarthritis. Intervention 1: Intervention group: light (Bioptron light) , The patients received (Bioptron) light and the same exercise program quadriceps isometric with ice which applied during first 3days after the operation. Intervention 2: Intervention group: LLLT (Low-Level Laser) or RJ laser, The patients received 804 nm GA AL AS LLLT (RJ laser) at power out of 500 mv and a degree of dosage 10J per session in 2 points (5J/Point) on posterior of the knee, which applied during first 3days after the operation. They receive same exercise and ice. Intervention 3: Control group: The Patients just received an exercise program with ice as in all groups.
