polviproteeseilla

Polviproteeseilla, commonly known as knee prostheses, are artificial devices used to replace damaged or diseased parts of the knee joint. This surgical procedure, called knee replacement or knee arthroplasty, aims to alleviate pain and restore function in individuals suffering from severe knee arthritis, injury, or other debilitating conditions.

The most common types of knee prostheses are total knee replacements and partial knee replacements. A total knee replacement involves resurfacing the entire joint, including the femur (thigh bone), tibia (shin bone), and patella (kneecap). A partial knee replacement, on the other hand, replaces only one or two of these components, typically when only a specific part of the knee is damaged.

Knee prostheses are usually made of durable materials such as metal alloys (like cobalt-chromium) and high-density polyethylene. These materials are chosen for their strength, biocompatibility, and resistance to wear. The components are designed to mimic the natural movement and structure of the knee joint, allowing for a range of motion and weight-bearing capabilities.

The decision to undergo knee replacement surgery is typically made after conservative treatments, such as medication, physical therapy, and injections, have failed to provide adequate relief. Factors such as age, activity level, overall health, and the severity of knee damage are considered when determining candidacy for the procedure. While generally successful, potential risks and complications can include infection, blood clots, implant loosening, and continued pain. Rehabilitation, including physical therapy, is a crucial part of the recovery process to regain strength, mobility, and function in the replaced knee.
