Examining muscle strength and stability after ACL reconstruction
Association of Strength and Proprioception Parameters With Qualitative Assessment of Functional Tasks After ACL Reconstruction
University Hospital, Caen · NCT06524869
This study looks at how muscle strength and balance after ACL surgery affect knee stability and the risk of re-injury in athletes.

What this trial studies
This observational study investigates the relationship between neuromuscular parameters and functional assessments in patients who have undergone anterior cruciate ligament (ACL) reconstruction. It focuses on measuring knee strength and proprioception using isokinetic dynamometry, alongside biomechanical assessments from functional tests such as single-leg hops and landing tasks. The study aims to understand how these factors influence knee stability and the risk of secondary ACL injuries during athletic activities, specifically at 6 to 12 months post-surgery.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18-40 who have had a first ACL reconstruction more than 6 months ago and are part of a sports medicine care pathway.
Not a fit: Patients with previous lower limb ligament surgeries, complex ligament injuries, or those with recent muscle injuries may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could enhance rehabilitation protocols and reduce the risk of re-injury for athletes recovering from ACL reconstruction.
How similar studies have performed: Other studies have shown success in using similar neuromuscular assessments to predict outcomes in ACL rehabilitation, indicating a promising approach.
