INTRODUCTIONOsteoarthritis or degenerative arthritis is the most common non-inflammatory degenerative joint disease. Osteoarthritis occurs more frequently in older adults, targeting both gender and usually including postmenopausal women. It usually affects weight-bearing joints such as the knee and hip, where the knee joint is mainly affected in India due to cultural and other practices such as sitting on the floor, kneeling, sitting cross-legged , squat, etc. (Jayanth Joshi, Parakashkotwal). Particularly, the rural population is more prone to such conditions due to activities involving increased physical stress, such as going to the bathroom in Indian toilets, sitting cross-legged during meals and heavy manual labor, while the urban population is less prone due to the involvement of technology which replaces and diminishes. manual loading. As aging occurs, cartilage begins to degenerate by flaking or forming tiny cracks. In advanced osteoarthritis, there is a complete loss of the cartilage cushion between the bones of the joints. Repeated use of worn joints over the years can mechanically irritate and inflame the cartilage, causing joint pain, stiffness and swelling. Osteoarthritis is classified into 2 large groups according to the cause: primary osteoarthritis and secondary osteoarthritis. Primary osteoarthritis is the most frequently diagnosed form of osteoarthritis. It is considered largely due to “wear and tear” from overtime. Age 50 to 60 is the strongest risk factor and the longer a person uses their joints, the more likely they are to suffer from this form of osteoarthritis. Secondary osteoarthritis results from conditions such as significant trauma, congenital joint abnormalities, metabolic defects, diseases and disorders that impair the normal function and structure of cartilage. Age groups 45 to 50 are more likely to be affected. Risk factors such as trauma, sedentary lifestyle, overuse of joints, and heredity lead to this type of osteoarthritis. However, the intensity of osteoarthritis symptoms varies from one individual to another; they generally become more severe, more frequent and more debilitating over time. Say no to plagiarism.

Subsequently, it becomes continuous even at rest. The joint becomes swollen due to synovitis and stiffness gradually sets in following intense pain. This makes movement painful and restricted, where crackling sounds are felt during passive movement of the joint. There may be some flexion deformity and advanced cases exhibiting genu varum deformity, ie. Lightness of the arc (Hunter Hsu et al,2018). Osteoarthritis treatment can be carried out in the form of non-surgical and surgical management. Non-surgical treatment options include physical therapy interventions, lifestyle modifications, weight loss, knee braces and supports, pharmacological support like NSAIDs and corticosteroids. surgical management includes osteotomy, unicompartmental knee arthroplasty, and total knee arthroplasty (Hunter Hsu et al, 2018). Physiotherapy interventions includeexercise therapy to strengthen surrounding structures, electrotherapy modalities for pain relief, thermotherapy, cryotherapy, supportive devices like orthodontic appliances, taping to improve the condition of patients. functional capacity and quality of life (Riann M.Palmeiri et al 2010) An important aspect in treatment planning is not only the diagnosis of the disease, but also the assessment of the level of disability and functional capacity. Studies have shown that diagnosis alone does not predict service needs, length of hospitalization, level of care, or functional outcomes. Although there are many questionnaires to assess the functioning of a person suffering from osteoarthritis, osteoarthritis researchers at Western Ontario and McMaster Universities (WOMAC) have found that it is commonly used in a clinical context with good validity and reliability. . The Western Ontario and McMaster Universities Osteoarthritis Index is commonly used to evaluate patients with osteoarthritis. It includes five questions on pain, two on stiffness, and seventeen on pain level. disability in performing ADLs (Mohammad H Ebrahimzadeh et al., 2015). Scores for each subscale range from 0 to 20 for pain, 0 to 8 for stiffness, and 0 to 68 for physical function. The sum of all subscores gives a total WOMAC score. A higher score indicates a serious condition, ie. increased pain, stiffness and functional limitations (WOMAC index, 2013). The World Health Organization developed the International Classification of Functioning, Disability, and Health, a multipurpose classification that helps organize information on functioning and disability by providing fine detail about health and its associated conditions. (WHO Geneva 2002). ICF provides a list of activities and participation similar to activities of daily living. It is useful to the person suffering from any form of disability, not only to identify their health care and rehabilitation needs, but also to identify and measure the level of disability and the effect of the physical and social environment that she experiences in her daily life. The functioning of individuals assessed by the ICF is the result of the interaction between bodily functions, body structures, activity and participation, and environmental factors. Changes in one component can influence other components. Although the International Classification of Diseases (ICD-10) is the most widely used classification, there is growing interest in the use of the ICF, particularly as it relates to disability. Defining and measuring disability is difficult because it involves many aspects of life and interactions between the person and their environment. In view of this, WHO launched a project on the assessment and classification of functioning, disability and health by representatives of more than 100 countries, researchers and consumers as part of an international collaboration , to produce the ICF as a universal framework (WHODAS 2.0). Although the ICF contains a detailed classification of functional individuals, which helps to diagnose a health problem by applying the ICF before it is diagnosed clinically, this seems to be a limitation because its use in daily clinical practice takes time-consuming and tedious (Sven Bolte et al., 2014). Quantitative and qualitative data can be organized through the ICF.PROCEDURESSample collection: Data was collected using the full core set of the International Classification of Functioning, Disability and Health (ICF) For.
