Objective: The aim of this study is to examine the relationship between kinesiophobia, pain, functional status and self efficacy in patients with knee osteoarthritis.

Material and Methods: The study was performed on 72 individuals diagnosed with Stage 2 and Stage 3 knee osteoarthritis according to the Kellgren Lawrence classification. The Tampa Scale for Kinesiophobia (TSK) was used to evaluate kinesiophobia, and the Visual Analogue Scale (VAS) was used to assess pain. The Western Ontario and McMaster Universities Arthritis Index (WOMAC) was used to asses the functional status. Self efficacy was assessed using the Arthritis Self Efficacy Scale (ASES).

Inclusion Criteria:

• Being between the ages of 40-85 and diagnosed with stage 2-3 bilateral knee osteoarthritis according to Kellgren Lawrence classification.

Exclusion Criteria:

• With a history of lower extremity surgery and a major trauma, orthopedic knee injuries such as tendinopathy, bursitis, ligament and meniscus injuries, a neurological or cardiopulmonary disease that may affect the evaluations, and any other joint in the lower limb that may cause reflected pain in the knee, individuals who had inflammatory rheumatic disease such as gout, rheumatoid arthritis, have participated in physical therapy and rehabilitation program in the last 6 months and who have been given knee injections
