Procedure Type of  Knee Replacement

Total Knee Replacement (TKR): Total Knee Replacement (TKR) involves removing damaged cartilage and bone from the surface of the knee joint and replacing it with an artificial joint made from metal and plastic. This surgery is generally recommended for patients with severe knee pain and mobility issues due to arthritis or injury. According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), TKR is a safe and effective procedure that can relieve pain, correct leg deformity, and help patients resume normal activities.

Partial Knee Replacement (PKR): Partial Knee Replacement (PKR) is suitable for patients with damage limited to just one part of the knee. Unlike TKR, PKR replaces only the damaged area of the knee, preserving more of the patient’s natural bone and tissue. As per the American Academy of Orthopaedic Surgeons (AAOS), PKR is less invasive than total knee replacement, potentially offering quicker recovery times and less post-operative pain, making it a preferred option for suitable candidates.

Revision Knee Replacement: Revision Knee Replacement is performed to replace an artificial knee joint that has failed due to infection, loosening, or other mechanical failures. This procedure can be more complex and challenging than primary knee replacement due to scar tissue, bone loss, and changes in anatomy. The Centers for Disease Control and Prevention (CDC) notes that revision surgeries may require specialized implants and techniques to achieve the best possible outcomes, emphasizing the importance of experienced surgeons and comprehensive patient evaluation.

Emerging Trends
