Did you know that your knee is the biggest joint you have in your body? You probably do not realize just how much you rely on your knees to perform most daily activities. The knee is made up of the bottom portion of the thighbone and the upper area of the shinbone. The bones connect and are covered with cartilage. Cartilage covers and protects the bones, allowing them to move with ease. There are C-shaped areas that cushion the joint between the femur and tibia. The knee also has huge tendons which hold the femur and tibia together and supply stability. The long upper leg muscle mass contributes to the overall strength of the knee. The surface areas of the knee are covered by the synovial membrane. This membrane layer oils the cartilage, lowering friction in a healthy knee.

Typically, all the parts of the knee operate together. Yet medical diseases or injury could cause the natural harmony of the way that the knee operates to be thrown off. This can cause people to experience pain, weakness, and inability to fully use their knee.

Chronic knee pain and impairment is often caused by joint inflammation. Although there are lots of types of joint inflammation, many knee issues are caused by three main conditions: osteoarthritis, rheumatoid joint inflammation, and post-traumatic arthritis.


  • This is a "deterioration" sort of arthritis. It typically occurs in people who are fifty years old and above, however, it can happen in younger individuals, too. The cartilage deteriorates which causes pain and can limit mobility.

Rheumatoid joint inflammation

  • This is a condition that makes the synovial membrane become inflamed. This creates swelling and inflammation which can damage the cartilage.

Post-traumatic arthritis

  • If the knee sustains serious injury, post-traumatic arthritis may occur. This can cause tears in the ligaments surrounding the knee. This can cause pain and restrict mobility.

A knee substitute (likewise called knee arthroplasty) may be more accurately called a knee "resurfacing" since the surface of the bones is only really changed.

There are 4 fundamental actions to a knee replacement treatment.

  1. Preparing for the replacement. The cartilage that is damaged in the areas located at the thigh and shin is removed in addition to a bit of underlying bone.
  2. Placement of the steel implants. The eliminated bone and surrounding cartilage are replaced with metal parts that become the surface area of the joint. These steel parts could be sealed or "press-fit" to the bone.
  3. Resurface the patella. The kneecap is cut and is resurfaced. It uses a medical-grade plastic switch. Some specialists choose not to resurface the patella. Resurfacing the patella depends upon the situation and needs of the patient.
  4. Place a space-holder. A medical plastic device is put in between the metal parts so that it is a smooth sliding surface area.
