What is Knee Replacement ? (Knee Arthroplasty pronounced as ARTH-ro-plas-tee) In simple terms, Knee replacement is a surgical procedure most often performed to relieve the pain and disability and restricted mobility arising out of degenerative arthritis. Major causes of debilitating pain include meniscus tears, osteoarthritis, rheumatoid arthritis, post trauma, ligament tears, and cartilage defects.

Different types of Knee Replacement surgeries

Yes, primarily there are two kinds of Knee replacement surgeries TKR (Total Knee Replacement) and UKR (Unicondylar / Partial Knee Replacement). Knee Replacement surgery can be performed as a partial or a total knee replacement. In general, the surgery consists of replacing the diseased or damaged joint surfaces of the knee with metal and plastic components shaped to allow continued motion of the knee joint. This is termed as Implant or Prosthesis.

Partial Knee Replacement (PKR)

Partial knee replacement, also called ‘unicompartmental knee arthroplasty or unicondylar knee arthroplasty’ is a surgery that may be considered for treatment of osteoarthritis of the knee joint where the complete knee joint does not require replacement. Traditionally, patients have undergone total knee replacement for severe arthritis of the knee joint. In a total knee replacement, all cartilage is removed from the knee joint, and a single metal and plastic
implant (prosthesis) is substituted.

Conditions for Partial Knee Replacement

The partial knee surgery may be possible if the arthritis in the knee is confined to a limited area. If the arthritis is widespread, then the partial knee replacement is not the solution. . In addition, the partial knee surgery is recommended in patients who are:

Total Knee Replacement (TKR)

In a Total Knee Replacement procedure, the surgeon removes damaged cartilage and bone from the surface of knee joint and replaces them with metal and plastic. In Total Knee Replacement, the surgeon replaces three parts of the knee joint. The two parts of the prosthesis are placed onto the ends of the femur, tibia, and undersurface of the patella using a special bone ement. Usually, metal is used on the end of the femur, and plastic is used on the tibia and patella for the new knee surface. However, surgeons are now using newer surfaces, including metal on metal or ceramic on ceramic.

Situations when TKR is helpful
  • Pain that limits activities such as walking, climbing stairs and getting in and out of chairs, or even moderate or severe knee pain at rest.
  • Restricted knee function or mobility, such as chronic knee stiffness and swelling that prevents one from bending and straightening the knee.
  • Failure of other methods to improve symptoms, for example, resting, weight loss, physical therapy, a cane or other walking aid, medications, braces and surgery, but they've failed.
  • Knee deformity, such as a joint that bows in or out.
What to expect post TKR surgery?

Reasons for Failure of Total Knee Replacement (TKR)

Like any other mechanical prosthesis (implant), knee implant also has a failure / malfunction possibility. There are several reasons which attribute to failure of a prosthesis (implant). Some of the major ones are:
  • Infection
  • Aseptic Loosening of the joint
  • Plastic Wear
  • Mal-alignment or Instability of the joint
  • Quality of the Implant
