   Introduction
 
Total joint arthroplasty, one of the most successful orthopaedic procedures, predictably relieves pain and improves function for patients with a painful arthritic hip joint1. This high success rate has increased patient expectations, particularly those regarding hip function, after the surgery. To achieve better function and to reduce the implant dislocation rate, more attention has been given to the role of the restoration of femoral offset and soft-tissue balancing2,3. Surgeons today are committed to restoring the anatomy in each case independent of the patient's age or sex or the pathological condition of the hip.

Anatomic studies of hip anatomy, specifically on the femoral side, have shown sex-based anatomic differences4-8. Women tend to have a shorter femoral neck, a thinner femoral shaft, a lower cervicodiaphyseal (CCD) angle, a lower femoral offset, and greater anteversion of the femoral neck (Fig. 1). These differences should be addressed during revision . . . [Full Text of this Article]
