Advanced hip osteoarthritis may not always require a hip replacement, according to updated guidelines from the American Academy of Orthopaedic Surgeons (AAOS) released in January 2024. The decision to undergo surgery is based on factors such as daily pain levels, loss of mobility, and how well the patient responds to non-surgical treatments, rather than solely on the appearance of the cartilage in imaging scans. Hip osteoarthritis occurs when the cartilage that cushions the joint gradually wears away, allowing the femoral head (the ball of the hip joint) to move improperly within the pelvic socket. This wear can also damage the surrounding bone, synovial membrane, and muscles, making the condition more complex than simple mechanical wear. Pain from hip osteoarthritis can spread to the groin, thigh, buttocks, and even the knee, which means a careful evaluation is needed to determine the exact source of discomfort. While X-rays can show a narrowing of the joint space, they are not the only factor in assessing the condition. Doctors also consider the patient’s mobility, muscle strength, and how much daily activity is affected by the pain. At early and moderate stages, non-surgical options such as adapted exercise, physiotherapy, and low-impact activities like indoor cycling or water-based exercises can help improve joint strength and flexibility. Losing excess weight can also reduce the mechanical stress on the hip. Non-steroidal anti-inflammatory drugs (NSAIDs) can help manage flare-ups, though they are not always suitable for long-term use. Corticosteroid injections may provide temporary relief, but AAOS guidelines suggest that hyaluronic acid injections do not offer significantly better results than a placebo. Patients should discuss the potential benefits, duration, and risks of each treatment with their specialist. A total hip replacement is considered when pain and stiffness severely impact daily life, such as causing trouble sleeping, dressing, or moving around. However, waiting until the patient is completely exhausted is not a medical recommendation, and a single flare-up is not enough to justify surgery. The decision to proceed with surgery depends on the diagnosis, the progression of symptoms, and the patient’s personal goals. Delaying surgery can allow time for better preparation, such as arranging home care, managing chronic conditions like diabetes, or quitting smoking. However, continuing ineffective treatments indefinitely does not protect the joint or improve quality of life. For most patients who undergo surgery, a hip implant significantly reduces pain and helps them regain lost activities. However, the procedure carries risks such as infection, blood clots, dislocation, and leg length differences. Recovery also requires re-education and adjustments at home. More than 95% of modern hip implants remain functional after ten years.
