The knee joint

Peer Reviewed The knee joint is an incredibly strong, intricate and complex part of human anatomy. It is the largest joint in the human body. Its role is to provide strength, support, and flexibility while standing, walking, and bending down.

The knee joint

Covering the ball, which is the head or end of the bone that rests in the socket, is cartilage. Cartilage is a slippery tissue that allows bones to glide smoothly over each other as we move and helps absorb the shock placed on the joints with movement.

If cartilage wears away, that cushion between the joints is lost, causing an issue known as bone on bone.


Knee joints are especially susceptible to this kind of wear and tear. The cause of this issue is usually osteoarthritis, which is a degenerative form of arthritis that affects the joints.

Bone on bone knee arthritis can also cause tiny pieces of bone and cartilage to break away and float within the joint space, causing further damage and pain. Symptoms Knee bone on bone symptoms begin gradually as the cartilage in the knee wears down.

Along with bone on bone knee pain, which can be quite severe, other symptoms often include: Stiffness, often worse after rest or sitting Grating or crunching sensation and sound when moving the knee Decreased flexibility and range of motion Inability to bend the knee Bone spurs are also a sign of bone on bone in the knee.

This extra bone results in bony growths that can cause pain and can sometimes be felt on the outside of the knee.

The knee: Anatomy, injuries, treatment, and rehabilitation

Causes Knee bone on bone is the direct result of severe degenerative changes in the knee joint from osteoarthritis. Bone on bone pain is felt when the cartilage in your knee joint has worn away and the joint space has narrowed enough to leave the bones exposed.

This causes them to rub against each other when you walk. There is no one cause of osteoarthritis, but there are several risk factors that can increase your chances of developing it. Risks Aging is the most common cause of bone on bone knee arthritis.

Approximately 50 percent of people over 65 worldwide show some evidence of osteoarthritis in at least one joint. This is mostly due to the wearing down of knee cartilage over the years. Other risk factors that can lead to bone on bone knee arthritis include:Symptoms of osteoarthritis include joint pain with activity, night pain, morning stiffness, limited motion, joint inflammation, crepitus or noise from the knee, and deformity.

Below are pictures of osteoarthritis in a knee joint. The knee joint is the hinged joint that allows the legs to bend. The upper leg bone (femur) and the larger lower leg bone (tibia) are connected via the knee joint.

The kneecap (patella) forms the protective bony covering for the knee joint. The Knee is an international journal publishing studies on the clinical treatment and fundamental biomechanical characteristics of this joint. The aim of the journal is to provide a vehicle relevant to surgeons, biomedical engineers, imaging specialists, materials scientists, rehabilitation personnel and all those with an interest in the knee.

WebMD's Knee Anatomy Page provides a detailed image and definition of the knee and its parts including ligaments, bones, and muscles. are the other bones that make the knee joint.
