Normal meniscus

Ligaments of the knee

Help to stabilize the knee
The collateral ligaments run along the sides of the knee and limit sideways motion.
The anterior cruciate ligament, or ACL connects the tibia to the femur at the centre of the knee.
Its function is to limit rotation and forward motion of the tibia.

The anterior and posterior cruciate ligament, or ACL and PCL

The ACL and PCL can be visualised well at knee arthroscopy and probed to check their integrity

This is a compilation picture with the arthroscopic pictures superimposed onto an MRI

The ACL is seen to sart from the front of the tibia within the knee and run up and out to attach to the back of the femur within the knee

Normal articular cartilage

The lining tissue of joints which cushions the knee, covering the bones of the joint

Normal meniscus

The lateral meniscus and medial meniscus: these are pads of cartilage that further cushion the joint, acting as shock absorbers between the bones

When we describe the knee, we can divide it into the inside of the knee (medial) and the outside of the knee (lateral).

Thus there are two menisci, the medial and lateral menisci.

p.s. menisci is pleural of meniscus
