ASI technique

Hip Osteoarthritis


The minimally invasive anterior approach for Total Hip Arthroplasty with the ASI technique (Anterior Supine Intermuscular) is performed through a small skin incision, without section of the muscles that surround and support the joint.
Compared to other methods, it has significant advantages..

  • The operation is performed without section or injury to the muscles, tendons and nerves. This means that:
  • Blood loss is less, so that a transfusion is generally avoided
  • Postoperative pain is significantly less
  • The patients can stand up on the first postoperative day
  • Very soon they go back to normal everyday activities, so that they avoid the danger of muscle atrophy, which is a common result of prolonged immobility
    • The ASI technique permits exact control of leg length during the operation, so that the danger of length discrepancy is avoided.
  • It permits control of stability of the joint during the operation, so that the danger of postoperative dislocation is reduced to practically zero.
  • X-ray control during surgery ensures optimal placement of implants.
  • The technique is suitable for all body types. Increased body weight does not affect the procedure, because the point of incision naturally has very little fatty tissue.
  • Total duration of the procedure is shorter than that of classic techniques.

The ASI technique of minimally invasive Total Hip Arthroplasty is applied by Dr Ioannis Tsarouhas at Athens Medical Center.
