A clinical-friendly motion capture system to evaluate knee instability in ACL-deficient patients

摘要

Background: Knee instability related to ACL-deficiency (ACLD) is an important criterion for diagnosis and decision of return-to-sports (RTS). Currently, the assessments rely on subjective physical examinations, while objective measurements with conventional motion capture system (MCS) is not readily available in most sports clinics. OptiKnee is a compact MCS that enables collection of knee kinematic data. In this study, we use OptiKnee to compare knee kinematics in ACLD patients with healthy controls.
