BJCDNN / Thursday, December 21, 2017 / Categories: Orthopedics & Spine Knee Surgery: Knowing What is Next Why have knee replacement surgery? During a knee replacement surgery, your surgeon removes worn-down bone and cartilage and replaces it with an artificial knee joint that replicates your knee’s natural rolling and gliding motion. This artificial joint (made of metal alloys, high-grade plastics and polymers) restores function to a severely damaged knee. Today, knee replacement is one of the safest and most successful types of major surgery. Who might be a candidate for knee replacement? The most common condition that results in the need for knee replacement surgery are: • Osteoarthritis- Characterized by the breakdown of joint cartilage and adjacent bone in the knees. • Other forms of arthritis- Rheumatoid arthritis and arthritis that results from a knee injury can also lead to degeneration of the knee joint. • Injury or Trauma to the Knee- Fractures, torn cartilage, and/or torn ligaments also can lead to irreversible damage to the knee joint over the years. The decision to replace the painful joint with an artificial one is a decision made by the patient and doctor.
