Hip replacement surgery can be performed using conventional technique (requiring a 10 to 12 inch incision) and minimally invasive technique ( requiring incision of 4 – 6 inch). As the minimally invasive hip replacement requires a much shorter incision, there is a lot less trauma or damage to the surrounding muscle and tissue, which promotes early recovery. Risk of infection and postoperative complications is also lesser in case of minimally invasive hip replacement. Most orthopedic surgeons prefer to use the minimally invasive approach because of its high success rate and benefits.
