The study aimed to determine differences in sagittal-plane joint biomechanics between athletes with and without knee osteoarthritis (OA) during drop vertical jump 2 years after anterior cruciate ligament reconstruction (ACLR). Forty-one ACLR completed motion analysis testing from 30 cm. Sagittal-plane peak angles moments contributions total support moment (TSM) were calculated first landing. Medial compartment OA of the reconstructed was evaluated using Kellgren-Lawrence scores (ACLR group: <2; ACLR-OA ≥2). group (n = 13) had higher hip lower surgical limb than their nonsurgical limb. Further, extension (P .024). significantly ankle plantar flexion TSM ≤ .032) group. landed increased moment, decreased TSM, compared may have adopted movement patterns decrease load compensated by shifting hip. Clinicians incorporate tailored rehabilitation programs that mitigate minimize risk ACLR.
