SURGICAL PROCEDURES

Total hip replacement using the Direct Anterior Approach (DAA)

Dr Blythe uses the DAA for all primary hip replacements unless there is severe deformity. Traditional approaches to performing total hip replacement require cutting muscles at either the back or side of the hip and then reattaching them at the end of the procedure. The DAA is performed by separating muscles at the front of the hip and avoids cutting any muscles.

The DAA is a variation on a surgical approach performed since the 1940’s and so is not “experimental”. In its modern form it is being used increasingly in Europe and North America and as an established hip approach. Dr Blythe uses implants that are the same as used in traditional hip replacement approaches and are not specific to the DAA. These are implants which have a proven track record.

ROBOTIC ASSISTED TOTAL HIP REPLACEMENT USING THE DAA

Dr Blythe was the first surgeon in Western Australia to perform a Robotic Assisted Total Hip Replacement using the DAA. This involves generating a 3D model of the pelvis and femur from a CT scan. On computer prior to the procedure the implant sizes and position are planned to as accurately as possible restore optimal anatomy. During the hip replacement performed through the DAA the robotic arm provides real-time feedback to position implants to replicate the 3D preoperative plan.
