Total Knee Replacement
Total knee replacement, also known as total knee arthroplasty, is a surgical intervention designed to address advanced knee arthritis and other debilitating knee conditions. It involves the removal of damaged or diseased components of the knee joint and their replacement with artificial components. This procedure is undertaken to alleviate severe pain, enhance mobility, and restore function in individuals whose knee joints have been significantly compromised by degenerative diseases or injuries.
Common causes of knee pain
- Rheumatoid Arthritis
- Post-Traumatic Arthritis
- Other Types of Arthritis
- Meniscus Tears
The surgical process begins with the patient being positioned on the operating table, and anesthesia is administered to ensure they remain pain-free and unconscious during the procedure. A surgical incision is made over the knee, providing access to the joint. The damaged or diseased bone surfaces, including the femur, tibia, and the underside of the patella, are removed or reshaped to accommodate the artificial joint components. These components, typically made from metal and plastic, are securely attached to the prepared bone surfaces. The alignment and positioning of these artificial components are crucial to ensure the knee's proper function and stability. Following the successful placement of the artificial components, the incision is closed, and a sterile dressing is applied.
Recovery after total knee replacement surgery involves a period of post-operative rehabilitation and physical therapy. These are essential steps to regain strength, range of motion, and mobility in the knee. While total knee replacement is highly effective in alleviating pain and enhancing the quality of life for individuals with severe knee issues, it is a significant surgical procedure, and the decision to undergo it is typically made after a thorough evaluation by an orthopedic doctor and careful consideration of the patient's overall health and lifestyle.
Total Hip Replacement
Total hip replacement, known as total hip arthroplasty, is a surgical procedure aimed at addressing severe hip joint pain and dysfunction resulting from various hip conditions. These conditions often include osteoarthritis, rheumatoid arthritis, hip fractures, and other disorders affecting the hip. The primary objective of this surgery is to alleviate pain, restore mobility, and enhance overall hip joint function.
COMMON CAUSES OF HIP PAIN
- Osteoarthritis (most common)
- Rheumatoid arthritis
- Osteonecrosis (avascular necrosis)
- Injury such as hip fracture
- Tumour in the hip joint
The procedure commences with the patient's placement on the operating table and the administration of anesthesia to ensure they remain pain-free and unconscious during the surgery. A surgical incision is then made, providing surgical access to the hip joint. Within the joint, the damaged hip socket (acetabulum) is reshaped, and the arthritic or damaged femoral head is removed. Following this, artificial joint components are meticulously affixed to the prepared bone surfaces. The acetabular component, often constructed from metal or plastic, is inserted into the hip socket, while the femoral component, typically made of metal, is attached to the femur. The insertion of a spacer between the components ensures smooth joint movement. The alignment and positioning of these artificial components are of paramount importance to guarantee proper joint function and stability. The incision is then meticulously closed with sutures or staples, and a sterile dressing is applied to the surgical site.
After a total hip replacement, patients embark on a period of post-operative rehabilitation and physical therapy. These essential steps are aimed at regaining strength, range of motion, and mobility in the hip joint. Total hip replacement is a highly effective surgical intervention that can significantly improve a patient's quality of life by reducing pain and enhancing hip joint function. The decision to undergo this procedure is typically based on a comprehensive evaluation by an orthopedic doctor, taking into account the patient's overall health and the specific hip condition they are facing.
