What this Trial Is About
Researchers are investigating how psychological readiness, knee function, and muscle strength relate after anterior cruciate ligament reconstruction (ACLR) using the Peroneus Longus tendon graft in male athletes. The study focuses on athletes recovering from ACL injuries who have undergone ACLR surgery, aiming to understand why some athletes meet the criteria to return to sport (RTS) while others do not. By examining both mental and physical recovery factors, the study hopes to improve rehabilitation strategies for safer and more effective return to sports. Participants attend a single evaluation session between 6 and 12 months after their ACLR surgery, after completing a standard rehabilitation program of at least six months. During this session, athletes are grouped based on whether they meet specific RTS criteria involving psychological readiness measured by the ACL-Return to Sport after Injury (ACL-RSI) scale, self-reported knee function using the International Knee Documentation Committee (IKDC) score, and isokinetic strength testing of quadriceps and hamstrings at various speeds. Functional tests like single-leg hops, balance assessments, and core endurance evaluations are also performed. During the visit, researchers collect data on psychological readiness, knee function, muscle strength, and functional performance through questionnaires and physical tests. Safety is monitored throughout the session, and detailed records are kept to ensure consistent testing conditions. The main outcomes include psychological readiness and isokinetic quadriceps strength, with additional measures such as hamstring strength, limb symmetry, and postural control. The study’s duration involves this single assessment, helping to identify factors influencing successful return to sport after ACLR with the Peroneus Longus tendon graft.

You will not qualify if you...
- Revision ACL reconstruction
- Prior ACL reconstruction on either knee
- Multi-ligament knee injury
- Concomitant meniscal repair or bilateral ACL reconstruction
- Knee pain greater than 3 out of 10 at evaluation that limits testing

1 visit (in-person)
Duration - 1 day
Participants attend a single evaluation visit between 6 and 12 months after ACL reconstruction. During this visit, participants complete self-report questionnaires on psychological readiness and knee function, undergo isokinetic strength testing at various speeds, and perform functional performance tests including hop tests, balance tests, and core endurance assessments.
