While TKA surgery has proven to alleviate pain, restore function and improve quality of life in patients with advanced degenerative arthritis of the knee, a sizable portion of the population is dissatisfied with their outcome. Numerous papers, mainly from the West, have shown this cohort to be about 18%. Factors such as associated low back pain, history of mental health problems, use of a fixed-bearing insert, and poor post-operative function have been shown to influence post-surgery outcomes negatively. However, most of these data are from western developed countries, and very few are from developing countries like India. Many factors are variable in patients from India who undergo TKA compared with patients from the West. Unlike the West, where a central healthcare system governs the modalities and delivery of healthcare, India has a multi-payer healthcare model paid for by a combination of private and public health insurance funds. Hence the factors responsible for dissatisfaction will be different for patients from India. Unlike the West, only 18% of total outpatients and 44% of inpatient care are in the public health sector. Variation in utilization of services across of the country also results in wide practice preferences among surgeons in surgeries like TKA.

Analysis of satisfaction outcomes following in TKA in India on a national scale will enable researchers analyse causes of dis-satisfaction, and also aim to improve outcomes in future. This multicentre observational study will help us analyse the satisfaction following TKA, across India.
