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.

Conditions

Anterior Cruciate Ligament Reconstruction

Outcome Measures

Primary Outcomes (4)

• Kinesiophobia

  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.

  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.

  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.

  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.

  Baseline

Secondary Outcomes (1)

• Return to sports after ACL injury

  Baseline

Eligibility Criteria

• Age: 18 Years - 35 Years
• Sex: all
