Home / Hip Revision Surgery


While rare, because it is a mechanical device, an artificial hip joint may fail due to mechanical or biological factors. To regain a level of mobility or alleviate pain symptoms, hip revision surgery may be required.

Because hip revision surgery is more complex our team of orthopaedic surgeons at Life Orthopaedic Hospital will conduct more detailed investigations prior to surgery. In general, though, the most common reasons for hip revision surgery are:

  • Repetitive hip dislocation occurs when the ball joint goes out of alignment with the hip socket. This may occur as a result of a hip fracture or multiple hip surgeries, or when the surrounding ligaments and muscles are not strong enough to hold the joint in place.
  • Mechanical failure of the hip joint may occur as a result of general wear. If patients are very active, continual repetitive movement may cause small pieces of the prosthesis to break off. This can result in an immune response which could further damage the bones and artificial joint. Mechanical failure of the artificial joint may also be a result of trauma, such as a car accident or fall.
  • Infection can occur at any time following surgery and is usually cause by bacteria entering the bloodstream. Depending on the severity of infection, interventions may range from surgical cleaning to a full prosthetic exchange, done in either one or two parts.

Dislocation is more likely to occur following a revision surgery and loosening of the prosthetic may occur due to poor fixation in patients compromised bone stock.  Bone fractures can occur either during or after surgery for the same reason. It may not be possible to fully correct leg lengths in complex cases. As with all surgical procedures there is always a risk of infection.

As a candidate for hip revision surgery, you will undergo a very detailed analysis with our team of orthopaedic specialists before a diagnosis and surgical approach is decided upon. For more details on what to expect, read our article on pathway to surgery.
