Primary | WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) | The WOMAC is a self-administered questionnaire consisting of 24 items divided into 3 subscales Pain (5 items): during walking, using stairs, in bed, sitting or lying, and standing upright Stiffness (2 items): after first waking and later in the day Physical Function (17 items): using stairs, rising from sitting, standing, bending, walking, getting in / out of a car, shopping, putting on / taking off socks, rising from bed, lying in bed, getting in / out of bath, sitting, getting on / off toilet, heavy domestic duties, light domestic duties. The test questions are scored on a scale of 0-4, which correspond to: None (0), Mild (1), Moderate (2), Severe (3), and Extreme (4). The scores for each subscale are summed up, with a possible score range of 0-20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function. Usually a sum of the scores for all three subscales gives a total WOMAC score. Higher scores on the WOMAC indicate worse pain, stiffness, and functional limitations. |

Secondary | KSS (Knee society score) | The Knee Society Score it comprises two parts, the first addressing pain, stability and range of movement. The second part examines function, with particular reference to walking distance and stair climbing. Maximum scores of 100 are possible in each section, consider a negitive outcome as zero. Grading for the knee Society Score Excellent: Score 80-100 Good: Score 70-79 Fair: Score 60-69 Poor: Score below 60. A Knee Society Score questionnaire will be used in the study. |
