Direct anterior total hip arthroplasty.

The direct anterior approach to hip arthroplasty has become a popular technique. This technique, which was described almost 70 years ago, allows the surgeon to approach the hip through an internervous and intermuscular plane. Preliminary studies show that direct anterior hip arthroplasty may allow patients to recover faster with a lower dislocation rate. It is helpful to understand the history, scientific basis, and surgical technique of direct anterior hip arthroplasty.
