BACKGROUND: This study describes a novel method for accurate evaluations of knee kinematics during arthroscopic reconstructions of anterior cruciate ligament (ACL). METHODS: Quantitative evaluation of knee stability was estimated by experimental validation on 30 volunteers and by statistical analysis of test repeatability. RESULTS: Proposed method present short learning time, is minimally invasive and thus suitable for arthroscopic techniques. Computed laxity showed a repeatability of 1.5 degrees for varus-valgus, 3 degrees for internal-external, and 2mm for antero-posterior tests. CONCLUSIONS: This method represents a reliable quantification of knee kinematics in surgery, able to improve present intra-operative assessment of knee stability.
