Why Is My Knee Pain?

The joint is made up of three bones. Thigh bone (femur) sits on top of your shinbone (tibia) you. If you bend or straighten your knee, the bottom of the thigh bone that moves round and round over the top of the tibia, the bone is called the kneecap (patella), which are connected by muscles that function to straighten your legs. The function of the patella is to subtract / absorb power pressure on the muscle.

In the normal knee joint, the surface of the ends of these bones are covered with cartilage smooth and supple. Cartilage serves to hinder direct meetings between the ends of the bones are jointed and reduce the friction that occurs when moving.

If the cartilage is damaged, the ends of the bones are going to meet each other, which will cause friction, pain and eventually damage cartilage further. Damage to cartilage is usually caused by various types of arthritis (joint inflammation), the most common is osteoarthritis. No drug or treatment can restore cartilage that has been damaged, in addition to joint replacement surgery (arthroplasty).

What Is Osteoarthritis (Liming JOINTS)?

Osteoarthritis (calcification of the joints) is a chronic joint disease, which is marked by a progressive softening of the cartilage, which eventually can lead to rupture of cartilage, in the accompanied growth of new bone and cartilage at the edge of the joint and the joint capsule thickening.

Osteoarthritis can be caused by many factors, including:

  • Injuries to the joint cartilage due to exercise, excessive consumption (over-used).
  • Age
  • Overweight (obesity)
  • Work
  • Accident.

The main symptom of osteoarthritis is pain, swelling and stiffness in the joints. Generally the knee, hip, lower back and fingers. Can also be found changes in shape and limited joint movement, especially in severe cases.

What Is Total Knee Replacement?

In total knee replacement surgery (arthroplasty), the ends of the bones replaced with metal and plastic (polyethylene). By using the right equipment, orthopedics surgeon will remove your damaged cartilage surfaces of all three bones in the knee joint. Then the new bone surface to be coated with the implant.

The surface of the bone will be replaced with a round metal part that almost resembles the curve of your original bone. The surface of the bone is replaced with a flat metal and is also covered with a plastic (polyethylene) that acts as cartilage. The bottom of the kneecap may also be replaced with a plastic (polyethylene).
