With this study is to evaluate knee joint position sense in patients with gonarthrosis under conditions with and without visual input.
Knee injuries, such as ligament ruptures or cartilage damage, can significantly impair proprioception. Previous studies have shown that individuals with knee injuries often exhibit reduced proprioceptive acuity, which may lead to altered movement patterns and consequently increase the risk of re-injury. Moreover, even asymptomatic knees may demonstrate proprioceptive errors due to underlying, undiagnosed conditions such as osteoarthritis, suggesting that proprioceptive dysfunction itself may contribute to injury occurrence. The role of visual input in the assessment of proprioception is also of considerable importance. Studies have demonstrated that visual feedback can enhance proprioceptive accuracy by providing additional sensory information that supports joint position sense. In contrast, the absence of visual cues has been associated with increased joint positioning errors, indicating that proprioception is not solely dependent on proprioceptive feedback but is also influenced by visual input. Investigating the interaction between visual and proprioceptive information is therefore crucial for the effective regulation of motor control.

Proprioception Measurement
During the measurement, the inclinometer was aligned so that its axis passed through the knee joint line, and it was positioned on the proximal one-third of the fibula and secured in place using a strap. Measurements were performed both with visual input and with visual input eliminated. After reaching the target position, the participant maintained the final position for 5 seconds before returning to the starting position.
Time frame: Each measurement was repeated three times with 1-minute intervals between trials. A 2-minute rest period was allowed between conditions involving changes in visual input.
