- Bones. Three bones meet to form your knee joint: the femur (thighbone), the tibia (shinbone), and the patella (kneecap). The patella sits in front of the joint to provide some protection.
- Articular cartilage. The ends of the femur and tibia, and the back of the patella are covered with articular cartilage. This slippery substance helps your knee bones glide smoothly across each other as you bend or straighten your leg.
- Meniscus. Two wedge-shaped pieces of meniscal cartilage act as shock absorbers between your femur and tibia. Different from articular cartilage, the meniscus is tough and rubbery to help cushion and stabilize the joint.
- Ligaments. Bones are connected to other bones by ligaments. The four main ligaments in your knee act like strong ropes to hold the bones together and keep your knee stable.
Knee sprains are injuries that happen when ligaments in your knee joint stretch too far or tear. Your knees are the biggest joints in your body. They connect your thigh bones ( femur) to your shin bones ( tibia ). Your knees allow you to move, bend and extend your legs.
Knee pain is an extremely common symptom that can result from everything from a temporary injury to a chronic condition like arthritis. You can usually treat knee pain at home with rest and over-the-counter medicine. Visit a healthcare provider if you’ve experienced an injury or have knee pain for more than a few days in a row.
