- 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.
1. Knee Fracture. Your patella, or your knee cap, protects your knee joints from injuries or further damage. When you fall or collide with an object or a person, your kneecap makes first contact and shields the different parts within your knee joint. This makes the kneecap susceptible to fractures.
- Fractures. The kneecap (patella) is a shield for your knee joint, and protects it from becoming injured or damaged during a fall. Because of this, the kneecap can become broken during a high impact fall or sports injury.
- Dislocations. Knee dislocations occur when the knee bones become out of place. This can occur after a major trauma such as a fall, car crash, or high-speed impact.
- Anterior Cruciate Ligament Injuries. The anterior cruciate ligament (ACL) is knee tissue that joins the upper and lower leg bones together and helps keep the knee stable.
- Posterior Cruciate Ligament Injuries. The posterior cruciate ligament connects the femur bone to the shinbone and keeps the shinbone from moving too far back.
Make an appointment with your health care team if your knee pain happened after forceful impact or injury. Or if your knee joint is: Badly swollen. Red. Warm and tender. Very painful. Also, call your care team if you have a fever or other symptoms of sickness. You could have an underlying illness.
Overview. Knee injuries involve trauma to one or more tissues that make up the knee joint: ligaments, tendons, cartilage, bones and muscles. These types of injuries may happen due to a fall, forceful twisting of the knee or high impact from a motor vehicle accident or another force.
