Total Knee Replacement
Total Knee Replacement (TKR), also known as Total Knee Arthroplasty (TKA), is a surgical procedure where the damaged or worn surfaces of the knee joint are replaced with artificial components. This surgery is typically performed to relieve pain and restore function in patients with severe knee arthritis or knee injuries that have not responded to conservative treatments.
Procedure Overview
- Preparation: The patient is anesthetized (either general anesthesia or spinal/epidural anesthesia).
- Incision: A surgical incision is made over the knee to access the joint.
- Removal of Damaged Tissue: The damaged cartilage and bone from the femur, tibia, and patella (if necessary) are removed.
- Implant Placement: Metal and plastic components are positioned to recreate the joint surfaces.
- Closure: The incision is closed with sutures or staples, and the knee is bandaged.
Benefits of Total Knee Replacement
- Pain Relief: Significant reduction or complete elimination of chronic knee pain.
- Improved Mobility: Restoration of knee function and movement, making daily activities easier.
- Enhanced Quality of Life: Increased ability to perform activities such as walking, climbing stairs, and engaging in low-impact sports.
- Long-Term Results: Modern prosthetics can last 15-20 years or longer with proper care.
- High Success Rate: Most patients experience substantial improvement in symptoms and quality of life.
Total Knee Replacement is generally recommended when other treatments, such as medication, physical therapy, or less invasive surgeries, have not provided sufficient relief from symptoms. It is important to discuss with an orthopedic surgeon to determine if TKR is the right option based on individual circumstances and health conditions.
