What are the causes of loos femoral component after total hip replacement?

Depends: Loosening of a hip prosthesis can be septic (caused by infection) or aseptic (mechanical loosening). Finally, traumatic (i.e. Fracture from fall) may also cause loosening. Your surgeon may order special blood work or radiology tests to determine the source.

Wear debris: The most common cause of loosening is from the reaction of the bone to the wear particles from the metal and plastic implant. All mechanical devices produce wear particles and your hip is no exception. These particles case a resorption of bone called "lysis". Loosening can also be caused by infection. Sometimes a fall can cause a fracture around an implant and this may loosen the component.
