Highlights
– Reduced patellofemoral contact force measured within 1 year after anterior cruciate ligament reconstruction (ACLR) is associated with worse trochlear cartilage structure 1–5 years later (pooled r = -0.48, 95% CI -0.63 to -0.31).
– No consistent relationship was found between early knee joint kinetics (e.g., knee flexion moment, knee adduction moment) and future tibiofemoral structural outcomes in pooled analyses.
