The number of primary total hip arthroplasty performed in recent years has been increasing. As a result, the number of revision hip arthroplasty is increasing in direct proportion. It is extremely important to accurately evaluate and surgically manage acetabular bone defects in revision hip arthroplasty. Evaluation and planning of the patient properly before the operation is essential for a successful outcome. A detailed history should be taken from the patient, physical examination should be done, and laboratory tests should be performed to rule out periprosthetic infection. Direct radiographs taken in accordance with the technique have a critical importance in the radiological evaluation of acetabular bone losses. In addition, it is possible to evaluate the structure of the acetabular bone defect in detail and to understand its 3-dimensional structure with computed tomography. Bone losses are defined by acetabular bone loss classifications, and possible surgical treatment options are determined. Although each reconstruction option has advantages and disadvantages in revision hip arthroplasty, its basic principles are similar and their aim is to achieve a stable structure. Surgical treatment options include; impaction grafting, reconstruction with structural allograft, reconstruction with cementless hemispheric acetabular component, modular porous metal augments, ring-cage reconstruction, cup-cage systems, and trafilange cup reconstruction.
