The goal of this observational study is to evaluate psychological readiness, kinesiophobia, subjective knee function, sport activity level, and return-to-sport status in athletes who have undergone primary anterior cruciate ligament (ACL) reconstruction between 3 and 24 months after surgery.
The main questions it aims to answer are:
Do these outcomes differ across different postoperative time periods? Are they associated with return-to-sport status? Participants will complete questionnaires assessing psychological readiness (ACL-RSI), kinesiophobia (TSK), subjective knee function (IKDC), and sport activity level (Tegner), and will provide information about their return-to-sport status.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Age ≥18 years.
* History of unilateral primary anterior cruciate ligament (ACL) reconstruction.
* Between 3 and 24 months after ACL reconstruction at the time of assessment.
* Regular participation in sports before ACL injury with a preinjury Tegner Activity Scale score of ≥4.
* Ability to read and understand Turkish and independently complete the study questionnaires.
* Willingness to participate in the study.
* Provision of written informed consent.
Exclusion Criteria:
* Revision ACL reconstruction.
* Reinjury or graft rupture of the reconstructed ACL.
* Bilateral ACL injury.
* History of ACL reconstruction in the contralateral knee.
* Concomitant major ligament, cartilage, bone, or extensor mechanism surgery that is expected to substantially affect rehabilitation, weight-bearing status, return-to-sport timing, or knee function following primary ACL reconstruction.
* Other lower-extremity injuries or surgical conditions unrelated to ACL reconstruction that limit sports participation at the time of assessment.
* Neurological, rheumatologic, cardiopulmonary, or other severe systemic diseases that substantially limit sports participation.
* Cognitive, psychiatric, or communication disorders that preclude reliable completion of the study questionnaires.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
