Overview

Case-control study reveals landing biomechanical asymmetries are independent of knee laxity in ACL reconstruction patients, suggesting functional deficits stem from movement strategies.

Key Points

To compare knee mechanics during bilateral drop vertical jump landings between patients following anterior cruciate ligament reconstruction and healthy controls, and to evaluate the relationship between landing asymmetries and knee joint laxity.
Evaluated 17 patients nine months post-anterior cruciate ligament reconstruction and 28 healthy controls using 3D motion capture (200 Hz) and two synchronized force platforms (1000 Hz).
Measured static anterior and internal rotation knee laxities bilaterally using dedicated arthrometers.
Analyzed group and leg differences with mixed-model ANOVA and assessed the relationship between sagittal energy absorption asymmetries and knee laxity via univariate linear regression.
Patients demonstrated 18% lower sagittal plane energy absorption in their involved leg during landing compared to controls (p = 0.018).
Involved knees exhibited 27% higher anterior laxity than non-involved knees (mean difference: 1.2 mm, p < 0.001) and 30% higher laxity than control knees (p < 0.001; leg-by-group interaction: p = 0.002).
Univariate linear regression revealed no significant relationship between side-to-side differences in sagittal plane energy absorption and knee joint laxity.
