Question

What is stage 4 knee damage?

Answer 1

Stage 4 knee damage is also known as severe osteoarthritis or end stage knee damage.

Stage 4 knee damage is the most advanced stage of osteoarthritis in the knee and results in near complete loss of the protective joint cartilage, which results in bone on bone contact.

This stage of knee damage at stage 4 severe osteoarthritis causes significant and often ongoing constant pain, stiffness, and structural changes like bone spurs, (osteophytes) and bone deformity.

With stage 4 knee damage or stage 4 severe osteoarthritis, daily activities also become limited severely, and stage 4 knee damage often requires surgical treatment like a total knee replacement.

The key symptoms of stage 4 knee damage or stage 4 severe osteoarthritis include.

Grinding, clicking or a feeling that your knee is stuck or locking up.

Frequent and unexplained swelling and a feeling of heat in the joint and inflammation.

Reduced mobility, like significant difficulty in walking, bending, standing or straightening your knee fully.

And intense pain that often persists even when resting or at night.

The main characteristics of stage 4 knee damage or stage 4 severe osteoarthritis include.

Cartilage loss, which is when the protective cushioning between your bones have worn away, which leads to direct friction between the bones.

Joint space narrowing, where a significant or near complete collapse of the space between the bones in the joint occurs, which can be seen on an X-ray.

Bone changes, like severe sclerosis, "hardening of the bone" and the presence of numerous, large bone spurs are common.

And joint deformity, where the joint may begin to show visible changes in shape, sometimes leading to conditions like bow leg or knock knees.
