What is the most common knee injury?
ACL injuries are one of the most common types of knee injuries and account for about 40 percent of all sports-related injuries. An ACL injury can range from a small tear in the ligament to a severe injury –when the ligament completely tears or becomes separated from the bone itself.
Why the human knee is a design disaster?
From elite athletes tearing their ACLs to senior citizens with chronic knee pain, there is clearly something error prone about the design of the human knee. It all comes down to a potent mix of evolutionary shortcomings and the stresses of modern life.
Are human knees badly designed?
The means this little delicate sack of fluid, cartilage, and tiny bones has to deal with the lever force produced by the longest, strongest bones in your skeleton. And it has to do it in three dimensions, twisting, rocking, hinging, and cantilevering its way through the day. Your knees are poorly designed.
What is the human knee called?
The smaller bone that runs alongside the tibia (fibula) and the kneecap (patella) are the other bones that make the knee joint. Tendons connect the knee bones to the leg muscles that move the knee joint.
What are the five most common knee problems?
Below are the most common types of injuries.
- Knee Fracture. Your patella, or your knee cap, protects your knee joints from injuries or further damage.
- Knee Dislocation. A knee dislocation occurs when the knee bones come out of place.
- Knee Ligament Injury.
- Meniscus Tear.
- Knee Tendon Tear.
How did our knees evolve?
The human knee is a triumph of design. The joint, which evolved fairly rapidly from our common ancestor with the chimpanzee to accommodate bipedalism, likely contributed to our success as a species. However, as the human lifespan extended, the flaw in the design emerged: pain, in the form of osteoarthritis.
Why do humans have knees?
It is the largest joint in the human body. The knee is a modified hinge joint, which permits flexion and extension as well as slight internal and external rotation. The knee is vulnerable to injury and to the development of osteoarthritis….

Why do humans have so many knee problems?
Less obvious knee problems can develop from osteoarthritis of the knee, when your cartilage has gradually worn away, leaving your knee vulnerable. Other joint diseases—like rheumatoid arthritis and lupus—can cause so much inflammation that they can permanently ruin your knees.
What is a knee made up of?
Your knee is made up of four main things: bones, cartilage, ligaments, and tendons. (femur), shinbone (tibia), and kneecap (patella). Your patella sits in front of the joint and provides some protection.
