Background: Osteoarthritis (OA) of the knee is a degenerative, non-inflammatory joint condition marked by articular cartilage disintegration and the growth of new bone (osteophytes) at the joint surfaces and borders. It impairs one’s ability to function and makes one disabled. It is the most common rheumatic disease. Because the Knee is a weight-bearing joint and a crutch joint, it is the most usually afflicted joint by Osteoarthritis.
Materials and Methods: A Correlational study was conducted to find out the correlation between Knee Society Score (KSS) and Oxford Knee Score (OKS) on 142 Osteoarthritis Knees. Purposive sampling was used to collect data from the Orthopaedics OPD at AIIMS Jodhpur from October to December 2018. 
Results: On evaluation, the mean age of the patients was 60.191.01. Bilateral Knee Osteoarthritis affected about 42% of the patients. Approximately half of the patients were obese. Only 34% of patients had compliance in physiotherapy. Analgesics and massage treatment are used by about 76% of the patients to relieve knee pain. In the Knee Society Score, the majority of the patients (82.4%) had a bad knee condition, with a mean score of 49.071.06. In OKS, about half of the patients (46.5%) had Moderate to Severe Knee Osteoarthritis, with a mean score of 22.697.09. The correlation coefficient between the Knee Society
Score and the Oxford Knee Score is 0.660. As a consequence of the analysis, both scales have almost the same outcome, indicating that they are moderately associated. The Knee Society Score is highly associated with occupation and physiotherapy, whereas the Oxford Knee Score is significantly related to the patients’ age alone.
Conclusion: According to the study, there is a moderate correlation between the Knee Society Score (KSS) and the Oxford Knee Score (OKS). These scores should be included during the diagnosis of Knee Osteoarthritis for improved patient care.
