Fear of re-injury after anterior cruciate ligament reconstruction surgery (ACLR) affects individuals' return to sports and physical activity negatively. The aim of this study is to evaluate the effects of proprioception and muscle strength on kinesiophobia in patients who have undergone anterior cruciate ligament reconstruction surgery.
Factors such as graft type, patient age, activity level and athletic experience, as well as psychological factors such as psychological readiness for return to sports, fear of re-injury, and motivation during the rehabilitation process, affect returning to sports after ACLR. Fear is a psychological reaction that occurs after injury and is clearly seen during the period when athletes continue to actively participate in sports. Individuals' confidence in their knees and pain after surgery affect their fear of movement. While kinesiophobia provides benefits in protecting injured body parts in the acute phase of pain, it can lead to inactivity, emotional stress and risk of re-injury in the long term. Kinesiophobia changes the biomechanics of movements and pain perception. Insufficient muscle strength and instability in the knee negatively affect confidence in the knee. The aim of this study is to evaluate the effects of proprioception and muscle strength on kinesiophobia in patients who have undergone anterior cruciate ligament reconstruction surgery.

RECRUITINGKinesiophobia
The Tampa Kinesiophobia Scale consists of seventeen items. Scores obtained from the scale range from 17 to 68, with higher scores indicating greater severity of kinesiophobia.
Time frame: Baseline
Joint position sense
Measurement of knee joint position sense by the active and passive repositioning technique with isokinetic dynamometer at 30˚ and 60˚.The deviation from the target angle is recorded in degrees. A high deviation from the target angle indicates a deficiency in proprioceptive sense.
Time frame: Baseline
Muscle strength
Assessment for knee extensor and flexor muscles with isokinetic dynamometer at 60 º/sec and 240º/sec angular velocity. The peak torque value (Nm), which is measured by the device and indicates the maximum force the subject can reach, will be used in the assessment.
Time frame: Baseline
Dynamic stability
The single leg dynamic stability test by the Biodex Balance System® (Biodex Medical Systems, Inc. USA). Low values of the stability index indicate better balance and stability, while higher scores indicate a lower ability to maintain postural stability.
Time frame: Baseline
Return to sports after ACL injury
The ACL Return to Sports after Injury (ACL-RSI) scale is a 12-item scale, scored from 0 to 10, that evaluates psychological readiness for return to sports after ACL injury. High scores indicate positive psychological readiness.
Time frame: Baseline
