Anatomy of the Knee Joint
The knee joint is a complex structure where the ends of two bones come together to facilitate painfree mobility. It is formed by the junction of the thigh bone (femur), the shin bone (tibia) and the knee cap (patella), which are held in place by various ligaments. The surfaces of these bones that articulate with each other are covered by a smooth and rubbery structure known as the articular cartilage.
Osteoarthritis is a common degenerative disorder (just like cataract) that primarily affects the weight-bearing joints in the body, such as the knees and hips, and occasionally smaller joints. In a healthy joint, the articular cartilage allows for smooth gliding motion and acts as a shock absorber during activities like walking. However, when the cartilage becomes damaged, it cannot be repaired by the body's natural healing mechanisms.
Over time, the cartilage thins out, leading to areas of the knee joint where no cartilage remains. This results in the bones rubbing against each other during weight-bearing activities like standing and walking, causing pain and stiffness. Other conditions, such as rheumatoid arthritis, septic arthritis may also cause osteoarthritis at younger age and may lead to pain and disability.
In the early stages of arthritis, pain, stiffness, and disability can often be managed with medications, lifestyle modifications, weight loss, exercises, and intra-articular injections like platelet-rich plasma (PRP) or hyaluronic acid.
However, there may come a point when these measures are no longer effective, and the arthritic changes have progressed to a stage where basic activities become painful and limitations in mobility are experienced. In such cases, a knee replacement surgery may be recommended as the most appropriate treatment option
Understanding Knee Replacement
Knee replacement surgery involves replacing damaged parts of your knee joint with a prosthesis made of metal (such as Titanium, Cobalt, Chrome, or Oxidized Zirconium) and a plastic spacer. There are different types of knee replacement surgeries available:
- 1. Unicondylar Knee Replacement / Partial Knee Replacement
- 2. Total Knee Replacement
- 3. Bicompartment Knee Replacement
Advantages of Knee Replacement
- Pain relief: Knee replacement surgery effectively alleviates chronic knee pain, improving overall comfort and quality of life.
- Increased mobility: Patients regain the ability to perform activities such as walking, climbing stairs, and engaging in physical pursuits.
- Improved quality of life: Knee replacement enhances daily functioning, mental well-being, and independence.
- Long-lasting results: The durable prosthetic components used in knee replacements ensure lasting relief and functionality.
- Customization options: Different types of knee replacement surgeries cater to individual needs, optimizing outcomes.
- Enhanced joint stability: Knee replacements provide improved joint stability, reducing the risk of falls and instability.
- Reduced medication dependency: Knee replacement reduces reliance on pain medications, leading to fewer side effects and improved well-being.
