Return-to-sport readiness after ACL reconstruction using the peroneus longus tendon

Official title: Correlation Between Psychological Readiness, Knee Function and Isokinetic Performance After Anterior Cruciate Ligament Reconstruction

Run by Cairo University · NCT07201597 · Data updated 2026-11-12

This project tests whether psychological readiness, self-reported knee function, and muscle strength differ between male recreational athletes who are or are not ready to return to sport 6–12 months after ACL reconstruction with a peroneus longus tendon graft.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are male recreational athletes aged 18–35 who participate in cutting/jumping sports, had primary unilateral ACL reconstruction with a peroneus longus autograft, completed ≥6 months of standardized rehab, and can attend a single 6–12 month postoperative evaluation.

Probably not a fit

Patients unlikely to benefit include those with revision or multi‑ligament reconstructions, prior ACL reconstructions, recent meniscal repair or bilateral ACL procedures, significant ongoing knee pain or limited range of motion that prevents testing, or those outside the specified age/activity criteria.

What this trial studies

This observational case-control, cross-sectional study enrolls male recreational athletes who underwent primary unilateral ACL reconstruction with a peroneus longus autograft and completed a standardized rehabilitation program. Participants attend a single evaluation visit 6–12 months after surgery and are classified as "RTS-ready" or "RTS-not-ready" based on a prespecified return-to-sport test battery performed that day. The protocol compares ACL-RSI psychological readiness scores, IKDC self-reported knee function, isokinetic quadriceps and hamstring strength and H/Q ratios, and measures of dynamic postural control and core endurance between groups. The goal is to identify an integrated physical and psychological profile that can better inform individualized return-to-sport decisions after this graft type.

Why it matters

Potential benefit: If successful, the findings could help clinicians combine psychological and physical measures to make safer, more individualized return-to-sport decisions and possibly reduce reinjury risk.

How similar studies have gone: Previous work has shown relationships between psychological readiness and strength metrics with return-to-sport outcomes after ACL reconstruction, but combining these measures specifically after peroneus longus autograft is relatively novel and less well studied.
