Description

Revision Total Knee Replacement (TKR) (TKR) and Total Hip Replacement (THR) are complex, specialized surgeries performed to replace worn, loose, or infected artificial joints, aiming to relieve pain and restore function. These procedures are more involved than primary replacements, often requiring bone grafts and specialized implants due to bone loss and scar tissue. Common reasons for revision include infection, mechanical loosening, instability, and fractures Key Aspects of Revision Surgery • Causes: The most common causes are aseptic loosening (implant coming loose without infection), instability, infection, and implant wear. • Complexity: Revision surgeries are longer, more complex, and require specialized tools compared to primary joint replacements. • Infection Management: Infections may require a two-stage revision, where the implant is removed and a temporary antibiotic spacer is inserted, followed by a second surgery for a new implant. • Risks: Complications include infection, blood clots, reduced range of motion, and bone fractures during surgery. • Recovery: Rehabilitation is generally slower, and functional outcomes might not be as high as in primary procedures • Key Procedures • Revision Knee Surgery: Involves removing the previous knee components and replacing them to address pain, swelling, or instability. • Revision Hip Surgery: Focuses on replacing the femoral component, liner, or acetabular cup to address loosening or instability.
