Artrosis of the Knee, Knee Osteoarthritis (OA)
Conditions
Brief summary
This observational study aims to investigate the relationships between proprioception, causes of kinesiophobia, sensory processing characteristics, and functional recovery in individuals undergoing gonarthrosis surgery. Postoperative functional recovery can be influenced by sensorimotor and psychological factors such as impaired proprioception, fear of movement, and changes in sensory processing. However, the interaction between these factors has not been sufficiently clarified. Participants will complete a sociodemographic and clinical information form, the Western Ontario and McMaster University Osteoarthritis Index (WOMAC), the Causes of Kinesiophobia Scale, and the Adolescent/Adult Sensory Profile. Proprioception will be assessed using the Joint Position Perception Test.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Womac | 04.04.2026-05.05.2026 | Womac is a widely used, self-administered questionnaire designed to evaluate pain, stiffness, and physical function in patients with knee or hip osteoarthritis. It consists of 24 items (5 for pain, 2 for stiffness, 17 for physical function). Higher scores indicate worse symptoms and greater functional limitations. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Proprioception Assessment | 04.04.2026-05.05.2026 | Proprioception (deep sense) assessment measures the body's ability to perceive its position in space, its movement, and joint angles. |
| Berg Balance Scale | 04.04.2026-05.05.2026 | The Berg Balance Scale is a 14-item, 0-56 point scored, highly valid, objective performance test used to measure static and dynamic balance and assess fall risk. It includes daily living movements such as getting up from a chair, standing, standing on one leg, and turning over. |
| The Causes of Kinesiophobia Scale | 04.04.2026-05.05.2026 | This is a validated and reliable tool in Turkish that helps identify the biological and psychological causes underlying fear of movement. It evaluates pain, fear of re-injury, and functional limitations in terms of their biological and psychological sub-dimensions. It is used in cases of chronic pain and avoidance of movement. |
| The Adolescent Sensory Profile | 04.04.2026-05.05.2026 | The Adolescent Sensory Profile is a scientific assessment tool that measures individuals' responses to sensory stimuli (sound, light, texture, movement, smell) in daily life. By identifying sensory processing patterns, it analyzes how sensitive a person is to environmental inputs or how they seek out these inputs. |
