Knee joint component
Bones
• The knee joint is one of the largest and most complex joints in the body
• The knee joint has three parts. The thigh bone (the femur) meets the large shin bone (the tibia) to form the main knee joint.
• The kneecap (the patella) joins the femur to form a third joint, called the patellofemoraljoint. The patella protects the front of the knee joint.
Ligaments
The knee joint is surrounded by a joint capsule with ligaments strapping the inside and outside of the joint (collateral ligaments) as well as crossing within the joint (cruciate ligaments)
We have 2 main types of ligaments
• Collateral ligament
