This section serves as an introduction to the world of knee replacement surgery and the innovative ROSA Robotic System. It sets the stage for understanding how robotic assistance is reshaping the landscape of orthopedic interventions.

Understanding Knee Replacement (Arthroplasty)

Knee replacement, at its core, is a surgical procedure designed to alleviate pain and restore function in a damaged knee joint. When conservative treatments such as medication, physical therapy, and lifestyle modifications no longer provide sufficient relief, arthroplasty emerges as a viable option.

Total Knee Replacement (TKR) vs. Partial Knee Replacement

There are primarily two main types of knee replacement: Total Knee Replacement (TKR) and Partial Knee Replacement, also known as Unicompartmental Knee Arthroplasty.

Total Knee Replacement involves replacing the entire knee joint surface with artificial components, effectively resurfacing the femur (thighbone), tibia (shinbone), and patella (kneecap).

Partial Knee Replacement, on the other hand, is a less invasive procedure that targets only the damaged compartment of the knee. This approach is suitable for patients with localized arthritis, where only one part of the knee joint is affected.

Knee Osteoarthritis (OA) as the Primary Indication

Knee Osteoarthritis (OA) stands as the most common indication for knee replacement surgery. OA is a degenerative joint disease characterized by the breakdown of cartilage, leading to pain, stiffness, and reduced mobility.

As the cartilage wears away, the bones of the knee joint rub directly against each other, causing inflammation and discomfort. OA can significantly impact a person's quality of life, making everyday activities such as walking, climbing stairs, and even standing difficult.
