Hip replacement is usually needed for severe hip pain and limited mobility caused by osteoarthritis, rheumatoid arthritis, avascular necrosis, fractures, or hip dysplasia. Key symptoms include persistent pain, stiffness, and difficulty walking or performing daily tasks. Surgical options include total hip replacement, partial hip replacement, or hip resurfacing, with approaches from the front, back, or side depending on anatomy and surgeon expertise. Experienced orthopedic surgeons at accredited hospitals with advanced technology ensure the best outcomes. In India, surgery typically costs between ₹2,00,000 and ₹5,00,000, with government schemes sometimes providing support. Post-operative care focuses on physiotherapy to strengthen muscles and improve flexibility, avoiding high-impact activities, and following medical guidance to prevent dislocation and ensure proper healing.
