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.
Male recreational athletes aged 18-35 years.
Participation in sports that involve deceleration, jumping, cutting, or turning (e.g., basketball, soccer, volleyball).
Primary unilateral ACL injury treated with ACL reconstruction using a Peroneus Longus autograft.
Single evaluation 6-12 months after ACL reconstruction.
Revision ACL reconstruction.
Prior ACL reconstruction on the ipsilateral or contralateral knee.
Multi-ligament knee injury.
Concomitant meniscal repair or bilateral ACL reconstruction.
The study population consists of male recreational athletes who have undergone anterior cruciate ligament reconstruction using the Peroneus Longus tendon. These athletes must meet specific criteria to return to sport and will be evaluated for both physical and psychological readiness. Participants will be assessed at least 6 months post-surgery, with both case (RTS) and control (non-RTS) groups based on their ability to return to sport.

Prospective
Not listed
Psychological Readiness to Return to Sport
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)
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.
Knee Function
Evaluated using the IKDC subjective score, this measure assesses knee function and symptoms, including limitations in daily and sports-related activities. A higher score indicates better knee function.
Isokinetic Performance (Quadriceps and Hamstring Strength at Different Velocities)
This outcome measures the strength of quadriceps and hamstrings at 60°/s, 120°/s, and 240°/s. The focus is on measuring peak torque, average power, and Hamstring-to-Quadriceps (H/Q) ratio to assess muscle strength recovery and balance.
Dynamic Postural Control
This measure evaluates an athlete's dynamic stability and ability to maintain balance through the Y-Balance Test, a functional movement test essential for preventing re-injury.
Core Muscle Endurance
The Prone Plank Test assesses the endurance of the core muscles, which are vital for overall stability, balance, and functional movements after ACL reconstruction.
