简要总结
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.
详细描述
Rationale and Objectives Anterior cruciate ligament reconstruction (ACLR) using a Peroneus Longus autograft is increasingly adopted; however, return-to-sport (RTS) decisions often emphasize strength or hop metrics while under-weighting psychological readiness. This single-center case-control study evaluates whether athletes who meet a predefined RTS test battery ("RTS-ready") differ from athletes who do not ("RTS-not-ready") in psychological readiness, knee function, isokinetic performance, hamstring-to-quadriceps (H/Q) strength ratio, and dynamic postural control/core endurance. The central hypothesis is that an integrated profile (physical + psychological) characterizes RTS-ready athletes and can inform safer, individualized RTS decisions after ACLR with Peroneus Longus.
Design and Setting Observational, case-control, cross-sectional assessment conducted in a university sports rehabilitation laboratory. Participants attend a single evaluation visit between 6 and 9 months post-ACLR after completing a standardized postoperative rehabilitation pathway. Group assignment (Case = RTS-ready; Control = RTS-not-ready) is determined by performance on the prespecified RTS battery during the same visit.
Participants Key inclusion and exclusion criteria (e.g., male recreational athletes in cutting/jumping sports; primary unilateral ACLR with Peroneus Longus autograft; exclusion of revision/multi-ligament injuries, significant pain or ROM limitation) are listed in the Eligibility Criteria section and are not repeated here.
Procedures and Test Order
All testing is performed in a single session by trained assessors after informed consent and a brief familiarization to minimize learning effects. To standardize workload and reduce fatigue and order effects, assessments proceed as follows:

结局指标
主要结局
Psychological Readiness to Return to Sport
时间窗: 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)
时间窗: 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.
次要结局
- Knee Function(Up to 9 months post-operative)
- Isokinetic Performance (Quadriceps and Hamstring Strength at Different Velocities)(Up to 9 months post-operative)
- Dynamic Postural Control(Up to 9 months post-operative)
- Core Muscle Endurance(Up to 9 months post-operative)
- Limb Symmetry Index (LSI)(Up to 9 months post-operative)
