PURPOSE The purpose of this study was to evaluate the influence of individual characteristics on rotational knee laxity in healthy participants. Our second aim was to verify whether the contralateral knee of patients with a non-contact ACL injury presents greater rotational knee laxity than a healthy control group. METHODS Sixty healthy participants and(More)
BACKGROUND Excessive physiological anterior and rotational knee laxity is thought to be a risk factor for noncontact anterior cruciate ligament (ACL) injuries and inferior reconstruction outcomes, but no thresholds have been established to identify patients with increased laxity. PURPOSE (1) To determine if the healthy contralateral knees of ACL-injured(More)
PURPOSE The aim of this study was to quantify sagittal and rotational knee laxity profiles taking into account individual influencing factors. METHODS Linear regression models were used to determine which individual characteristics (age, height, body mass and sex) influenced the outcome in a group of 104 healthy subjects. The standardized residuals were(More)
PURPOSE This study analysed whether associating the side-to-side difference in displacement and the slope of the load-displacement curve of anterior and rotational knee laxity measurements would improve the instrumental diagnosis of anterior cruciate ligament (ACL) ruptures and help to detect different types of ACL tears. METHODS Anterior and rotational(More)
