Kinesiophobia after total knee arthroplasty is an important parameter affecting recovery. However, the relationship between kinesiophobia and the factors it may cause is not clear. Therefore, this study aimed to examine the relationship between kinesiophobia, pain, fear of falling, mobility and proprioception in the early period after total knee arthroplasty.

Various biopsychosocial factors affect the recovery process and quality of life after total knee arthroplasty. This situation reaches a level that can affect the daily life activities of patients, especially in the long term. Especially kinesiophobia is one of these factors. This condition also affects the proprioceptive sense in the knee, the capacity to move and the fear of falling. However, studies have generally examined long-term effects after total knee arthroplasty. Early studies are limited in number. More studies are needed to better understand the relationship between kinesiophobia and biopsychosocial factors. Additionally, the lack of relationship between the patients' kinesiophobia level, fear of falling, and proprioception in the early period after TKA draws attention. Therefore, this study aimed to examine the relationship between kinesiophobia, pain, fear of falling, mobility and proprioception in the early period after TKA.

Inclusion Criteria:

• Being between the ages of 18-80
• Total knee arthroplasty surgery due to knee osteoarthritis
• Volunteering to participate in the study

Exclusion Criteria:

• Previously had knee surgery or fracture
• Diagnosed with rheumatoid arthritis
• Those with severe obesity (BMI > 40 kg/m2)
• Those with sensory and motor impairments
• Revision knee arthroplasty planned
• Venous thromboembolism
• Neurological diseases (MS, Parkinson, etc.)
• Early post-surgical complications

Individuals who have undergone total knee arthroplasty surgery will be included in the study. Patients will be divided into two groups, high and low kinesiophobia levels, according to the Tampa Kinesiophobia Scale.
