2- Direct anterior approach
In this approach, the surgeon enters the joint between the tensor fascia latta and Sartorius muscle. Dr Joel Matta and Dr Bert Thomas adopted this approach because it showed promising results regarding post-operative hip dislocation, but with modern techniques, and new implant shapes, dislocation rates are now comparable between anterior and posterior approaches.
According to a study by Maratt JD et al., no difference in hip dislocation rates were noted between anterior and posterior approaches in total hip arthroplasty surgery.
Advantages of this approach include:
- Improve the post-operative functional ability of the hip joint
Disadvantages of this approach include:
- Loosening of femoral component of the hip joint
- Early revision surgery in comparison to other approaches
- Increases rate of wound complications
- Femoral exposure is difficult than posterior technique
- Increase the risk of lateral femoral nerve injury (LFCN)
