PROPRIOCEPTION, KINESIOPHOBIA AND FUNCTIONAL RECOVERY AFTER GONARTHROSIS SURGERY

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.

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • The study included individuals aged 50-75 years who had undergone unilateral total knee arthroplasty and were 4-6 weeks post-operatively. Participants were required to have the cognitive capacity to understand the study instructions and to be able to walk independently.

Exclusion criteria

  • Individuals who had undergone bilateral total knee arthroplasty, those with advanced osteoarthritis in the other knee, those with neurological or orthopedic diseases affecting mobility, those who had undergone another major joint surgery within the last six months, and those with vestibular system disease were excluded from the study.

Treatment and study plan

Primary outcomes

  1. Womac

    Time frame: 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 outcomes

  1. Berg Balance Scale

    Time frame: 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.

  2. Proprioception Assessment

    Time frame: 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.

  3. The Causes of Kinesiophobia Scale

    Time frame: 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.

  4. The Adolescent Sensory Profile

    Time frame: 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.
