Ultimate Overview of Knee Repair and Replacement Surgeries

This comprehensive guide covers knee surgical procedures including partial and total knee replacements. It explains knee anatomy, types of surgeries, and recovery considerations. Ideal for patients seeking detailed insights into knee repair options, highlighting benefits and risks for informed decisions.

Ultimate Overview of Knee Repair and Replacement Surgeries

Knee surgical procedures are designed to fix or replace damaged parts of the joint. These techniques include partial and full knee replacements, as well as targeted repairs for specific issues within the knee structure.

Knee Anatomy Explained
The knee consists of three main bones: the thigh bone (femur), the shinbone (tibia), and the kneecap (patella). Ligaments and tendons support these bones, providing stability and enabling motion. The fibula, a slender bone beside the tibia, offers additional support. Key ligaments such as the anterior and posterior cruciate ligaments connect the femur and tibia, while collateral ligaments on the sides prevent excessive movement. The patellar tendon links the kneecap to the femur.

Types of Knee Surgical Procedures

Partial Knee Arthroplasty

This procedure is suitable when damage is confined to a single compartment of the knee, often resulting from osteoarthritis or rheumatoid arthritis. Rheumatoid arthritis is an autoimmune condition where the immune system attacks joint linings, leading to deterioration. Osteoarthritis involves cartilage wear, exposing bone surfaces. In such cases, only the affected segment of the joint is replaced with metal or plastic components.

Full Knee Arthroplasty

When the entire knee joint is compromised, total knee replacement is performed. Under anesthesia, the surgeon removes damaged parts of the femur, tibia, and kneecap, replacing them with durable artificial joints made of metal and polyethylene. Recovery involves physiotherapy, and while effective, there are risks such as infections, blood clots, and ongoing pain. Properly implanted joints can last 20-25 years, though early failures can occur.
