Real knee motion in CAD , the best if it is in Solidwords

Where I can get for free or buy a knee joint complete anatomy ( including femur, tibia, meniscus, ligament, and cartilage). I need a knee joint with accurate knee motion for flexion-extension, internal and external rotation. It supposed to be real human motion. If possible I need it in CAD, it is the best if I can get in Solidworks assembly motion. Really appreciate the information. Thank in advance
