To explore whether static and dynamic tibial translation are correlated. Methods: Ten patients undergoing quadruple hamstring tendon graft ACL reconstruction were evaluated before, 5weeks after, and 5years after ACL reconstruction. Sagittal tibial translation was measured during the Lachman test (static translation) and during gait (dynamic translation) using a CA-4000 electrogoniometer. Results: Five years after ACL reconstruction, static tibial translation did not differ between knees (Lachman test 90N and 134N n.s.). In contrast, there was greater maximal anterior tibial translation during gait in ACL-reconstructed knees than in uninjured knees (5.5±1.4 vs. 4.5±1.6mm, P=0.028). There were no differences in static or dynamic tibial translation between the 5-year follow-up and before ACL reconstruction or between the 5-year follow-up and the 5-week follow-up. There were no correlations between static and dynamic tibial translation. Conclusion: Although static tibial translation did not differ between knees 5years after ACL reconstruction, dynamic tibial translation during gait was greater in ACL-reconstructed knees than in uninjured knees. Neither static nor dynamic tibial translation changed 5years after ACL reconstruction as compared to before surgery and 5weeks after surgery. Static tibial translation did not correlate with dynamic tibial translation. Clinical relevance: This study indicates that although the knee is stable during static measurements, kinematics during gait is impaired 5years after ACL reconstruction. This may affect the return to sport and risk of osteoarthritis. Level of evidence: Case series, Level IV.
