Posterior total hip replacement has been the most common approach for total hip replacement for many years. In this approach, the patient is positioned on their side, and an incision is made down the side of the buttock. The incision is typically 15-20cm long, but this varies depending upon patient size and the type of hip replacement being undertaken. The gluteus maximus muscle is split, and the small muscles at the back of the hip are divided and later repaired. This approach gives excellent exposure of the hip joint and upper part of the femur. It is particularly useful in patients who have significant underlying anatomical deformity, have had previous surgery, or require revision(replacement) of existing hip implants.
The operation takes roughly 1-1.5hrs, and most patients will be up walking either the day of surgery or the day after. They will normally in hospital for 4-5days and then discharged home when safe.

Modifications of the Posterior Approach
In a bid to reduce soft tissue damage and cutting muscles, various modifications of the posterior hip approach have been made. These use smaller incisions, and aim to cut less muscles and tissue than the traditional posterior approach. These approaches include the:
- Superpath Hip Replacement
- Direct Superior Hip Replacement
Severe bilateral hip dysplasia which is suitable for posterior total hip replacement
