AVN of the hip does not appear overnight. It moves through four identifiable stages as blood supply to the femoral head is disrupted and bone tissue begins to die, most often classified using the Ficat and Arlet system. Each stage marks a different point in that...
TL;DR: If avascular necrosis (AVN) of the hip is diagnosed in Stage 1 or early Stage 2 before the femoral head collapses, core decompression may reduce pain, improve blood flow, and delay or avoid hip replacement in selected patients. MRI is the most important test...
Robotic knee replacement uses a computer guided robotic arm and a 3D joint model to plan bone cuts and implant position. Manual surgery relies on handheld instruments and physical alignment guides instead. Both place the same implants, so the real difference comes...
A revision knee replacement typically holds up for 10 to 15 years, with some implants performing well past 20. Revision knee replacement surgery tends to have a shorter working life than a first time replacement, mainly because there’s less healthy bone to...
