This clinical trial aims to investigate the correlation between psychological readiness, knee function, and isokinetic performance after anterior cruciate ligament reconstruction (ACLR) using the Peroneus Longus tendon graft (PLT). ACL injuries are common among athletes, and the standard treatment is ACL reconstruction surgery (ACLR). However, the success of the surgery does not solely depend on physical recovery but also on the psychological readiness of athletes to return to their sport.
This study focuses on athletes who have undergone ACLR using the Peroneus Longus tendon (PLT). The primary objective is to compare psychological readiness, self-reported knee function (IKDC score), isokinetic performance (quadriceps and hamstring strength), and muscle strength ratios between athletes who meet return-to-sport (RTS) criteria and those who do not.
Psychological readiness will be assessed using the ACL-Return to Sport after Injury (ACL-RSI) scale, while knee function will be evaluated using the IKDC subjective score. Isokinetic testing will assess quadriceps and hamstring strength at various angular velocities. This study aims to provide a more comprehensive understanding of the factors influencing an athlete's ability to return to sport after ACLR, combining both physical and psychological aspects.
The results will help optimize rehabilitation strategies by offering a multidimensional approach, considering both physical and psychological factors, to improve recovery protocols for ACL-injured athletes.

* Able to provide written informed consent.
Exclusion Criteria:
* Revision ACL reconstruction.
* Prior ACL reconstruction on the ipsilateral or contralateral knee.
* Multi-ligament knee injury.
* Concomitant meniscal repair or bilateral ACL reconstruction.
* Knee pain \> 3/10 at evaluation that prevents or impairs testing.

Primary outcome measure(s)
Psychological Readiness to Return to Sport — Up to 9 months post-operative Psychological readiness to return to sport measured by the validated Arabic version of the ACL-Return to Sport after Injury (ACL-RSI). Total score 0-100; higher scores indicate greater psychological readiness.
Isokinetic Strength Performance (Quadriceps Strength at Various Velocities) — Up to 9 months post-operative This measure evaluates quadriceps strength at 60°/s, 120°/s, and 240°/s using the HUMAC NORM Isokinetic Dynamometer. It assesses peak torque and average power production in both the injured and uninjured limbs.
