Understanding Hip Replacement Failure and Revision Surgery
Causes of Hip Replacement Failure: Hip replacements may fail for various reasons. Earlier hip implants had an average lifespan of 15-20 years, but advancements such as uncemented stems, and highly cross-linked poly, and ceramic heads have extended the life span to over 30 years. Previously, hip replacements failed due to polyethylene wear over time, leading to implant loosening and failure. Other causes of hip revision include periprosthetic fractures, infection, dislocation of the hip, and metal sensitivity.
Symptoms of Failure: Patients experiencing hip replacement failure may present with pain, limping, and difficulties carrying out their daily activities.
Revision Hip Arthroplasty: In a revision hip arthroplasty, the loose or failed components are removed using specialized instruments, and the bone is thoroughly cleaned of debris. Special implants designed for revision are then used, integrating into the native bone. Surgeons may also use bone grafts to reconstruct bone defects. Revision hip arthroplasty is a major surgery, more time-consuming, and requires longer incisions due to scar tissue. It demands considerable surgical skill and specialized instrumentation to ensure successful outcomes. However, the procedure carries a higher risk of complications, such as sciatic nerve palsy, dislocation, stiffness, heterotopic new bone formation, periprosthetic fracture, and blood loss compared to standard hip replacement.
Recovery and Precautions: Recovery from revision hip arthroplasty usually takes 6 weeks to 3 months. Patients may be recommended to use standard hip replacement precautions, such as an abduction pillow and walking aids like a stick or walker. Improvement may continue for up to 2 years after surgery.
