Total Hip Replacement (THR), also known as total hip arthroplasty, is a surgical procedure to replace a damaged or diseased hip joint with an artificial implant. This life-changing procedure is one of the most successful orthopedic surgeries worldwide, providing significant pain relief and restoring mobility to patients suffering from severe hip conditions including osteoarthritis, rheumatoid arthritis, avascular necrosis, hip fractures, and post-traumatic arthritis. At Arthroscenter in Patna, Bihar, Dr. Gurudeo Kumar has established himself as a leading hip replacement surgeon with over 1,500 successful total hip replacement surgeries performed with exceptional outcomes. Our state-of-the-art facility utilizes the latest ceramic-on-ceramic and metal-on-metal prosthetic technology, minimally invasive surgical techniques, computer-assisted navigation systems, and customized implant options to ensure precise implant placement and optimal long-term results for every patient. The hip joint is one of the body's largest ball-and-socket joints, where the femoral head (ball-shaped top of the thigh bone) fits into the acetabulum (cup-shaped socket) of the pelvis. This design allows for a wide range of motion necessary for walking, sitting, climbing stairs, and daily activities. When arthritis, injury, or disease damages these surfaces, the protective articular cartilage wears away, causing bone-on-bone contact that results in severe pain, inflammation, stiffness, and progressively limited mobility. Hip replacement surgery addresses this problem by removing the damaged femoral head and acetabular cartilage and replacing them with smooth artificial components. The femoral component consists of a metal stem inserted into the thigh bone with a ceramic or metal ball attached to it. The acetabular component is a metal cup lined with plastic, ceramic, or metal that creates a new smooth socket. When properly positioned, these components restore pain-free motion and stability to the hip joint. Modern hip replacement surgery has evolved significantly over the past two decades. At Arthroscenter, we offer multiple surgical approaches including the anterior approach (front of hip), posterior approach (back of hip), and lateral approach, each selected based on patient anatomy and specific needs. Minimally invasive techniques use smaller incisions (3-4 inches compared to 8-10 inches traditionally), resulting in less muscle damage, reduced blood loss, faster recovery, and smaller scars. Dr. Gurudeo Kumar's expertise extends to complex cases including revision hip replacements, dysplastic hips, and hip replacements in younger patients requiring high-performance implants. Our comprehensive approach includes pre-operative optimization, advanced anesthetic techniques including spinal anesthesia with nerve blocks for superior pain control, and structured rehabilitation protocols developed in collaboration with experienced physiotherapists. Most patients experience dramatic improvement in quality of life after hip replacement. The procedure typically takes 1.5-2.5 hours, and patients usually stay in the hospital for 2-4 days. With modern surgical techniques, enhanced recovery protocols, and comprehensive rehabilitation programs at Arthoscenter, patients can return to most daily activities within 3-6 months, with continued improvement up to one year post-surgery. The success rate exceeds 95%, and modern hip implants with advanced materials and designs can last 20-30 years or longer with proper care, making hip replacement one of the most cost-effective and life-improving surgical interventions available.
