Proprioception, Muscle Strength and Kinesiophobia After Anterior Cruciate Ligament Reconstruction

Recruiting

• Conditions: Anterior Cruciate Ligament Reconstruction

• Registration Number: NCT06538792
• Lead Sponsor: Bezmialem Vakif University

Brief Summary

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.

Detailed Description

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.

Primary Outcome Measures

Name	Time	Method
Kinesiophobia	Baseline	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.
Joint position sense	Baseline	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.
Muscle strength	Baseline	Assessment for knee extensor and flexor muscles with isokinetic dynamometer at 60 º/sec and 180º/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.
Dynamic stability	Baseline	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.

Secondary Outcome Measures

Name	Time	Method
Return to sports after ACL injury	Baseline	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.
