Hip resurfacing is a surgical technique that involves resurfacing the damaged bone and cartilage of the hip joint rather than replacing it entirely with a prosthetic implant. The document discusses hip resurfacing and is authored by Dr. Jean-Louis Leflot, who works at the Military Hospital Queen Astrid and University Hospital Mont-Godinne in Belgium. Dr. Leflot believes hip resurfacing is a more preserving surgery that allows for better stability and proprioception compared to a full hip replacement.
