Knee endoprosthesis (total)


When Is Total Knee Replacement Necessary? The knee joint is one of the most heavily used joints in the human body. Daily activities such as walking, climbing stairs, and physical exercise place constant stress on the joint. Over time, cartilage degeneration, injury, or disease can lead to chronic pain, stiffness, and significant mobility limitations. When conservative treatment methods no longer provide sufficient relief, total knee replacement becomes one of the most effective solutions. The procedure replaces damaged joint surfaces with an artificial implant designed to restore function and reduce pain. Today, total knee arthroplasty is among the most successful and widely performed orthopedic procedures worldwide.

What Components Make Up a Total Knee Implant?

Modern knee replacement systems are engineered to replicate natural knee biomechanics.

A standard implant typically includes:

  • Femoral component;

  • Tibial component;

  • Polyethylene insert;

  • Patellar component (when required);

  • Fixation elements.

Advanced materials provide durability, stability, and smooth joint movement following surgery.

 

Which Conditions Require Total Knee Replacement?

Total knee arthroplasty is commonly performed for severe joint damage.

Typical indications include:

  • Knee osteoarthritis;

  • Rheumatoid arthritis;

  • Post-traumatic arthritis;

  • Knee deformities;

  • Avascular necrosis;

  • Complex fracture complications;

  • Failed previous surgical treatments.

Early intervention often helps patients regain mobility and improve quality of life.
