Coronary ligaments of the knee are:
Ligaments connecting the menisci to femur
Ligaments connecting the menisci to tibia
Ligaments connecting the anterior horns of both menisci
Ligaments connecting the lateral meniscus to capsule
Coronary ligaments attach the outer border of the menisci with the tibial edge and restrict their movements. Ref: Anatomy of The Human Body By Henry Gray, 20th Edition, Chapter 3
