Anterio-lateral is not the same as direct anterior. Its on the side of the hip. Posterior is from the back and anterior in the front. My OS likes anterio-lateral as he feels it is the most proven for results in the end - but most people having anterior (or Superpath) seem to heel a little faster as the incision is smaller and trauma to internal tissue is less. I am a little over three weeks since my surgery, can walk with a cane or a little by myself, do not have a lot of pain, mostly have regained my energy. Probably biggest difference is that the OS puts more restrictions on movement in the first 3-6 weeks (no bending more than 90 degrees, no twisting or crossing operated leg past midline).
