Can a hip replacement partially dislocate?

Dislocation is uncommon. The risk for dislocation is greatest in the first few months after surgery while the tissues are healing. If the ball does come out of the socket, your doctor can perform a procedure (called a closed reduction) that can usually put it back into place without the need for more surgery.

It is often associated with osteolysis (bone resorption) and an inflammatory cellular response within the joint.

What causes aseptic loosening?

Aseptic loosening can be the result of inadequate initial fixation, mechanical loss of fixation over time, or biologic loss of fixation caused by particle-induced osteolysis around the implant.
