Achieving Stability in Revision Total Hip Arthroplasty

Instability remains one of the leading causes of revision total hip arthroplasty. It is important to understand the etiology of recurrent instability prior to surgical intervention to solve instability. Understanding the patient factors and surgical factors that lead to instability is critical. Once the decision to have surgery has been made, it is critical to correct the problem that lead to instability. Today, several options exist to help reduce the risk of instability, but correction of component malposition is the most critical. This chapter reviews current options in the treatment of recurrent instability.
