Minimally Invasive Hip Replacement Surgery

Traditional and Minimally Invasive Hip Replacement

People with severe arthritis or a fracture, usually undergo a hip replacement surgery. With the advancement of the medical science, minimally invasive hip replacement surgery is now being used by surgeons worldwide. This procedure aims at reducing the trauma to the joints and muscles.

Unlike traditional surgery, wherein an incision of 8-10 inches at the lateral side, minimally invasive surgery requires only 1-2 inches incision and operates from the front. Traditional hip replacement required a great effort and removal of many joints and muscles before reaching the hip joint. On the other hand, minimally invasive surgery overcomes all the disturbance given to the muscles.

Traditional Hip Replacement Surgery:

  • An incision of 10-12 inches is made.
  • The surgery is performed from the lateral side.
  • The muscles are detached from the hip.
  • The damaged head is removed and substituted with a metal stem and a metal or ceramic ball is placed on its head.
  • The socket which was damaged is removed and replaced with an implant.
  • A spacer made of either hard plastic or metal is placed.

Minimal Invasive Hip Replacement:

In minimal Hip replacement surgery, the procedure for surgery is same. The devices and implants used are also similar. However, the method of surgery differs slightly.

  • Single incisions of 1-2 inches are made.
  • Less disturbance is caused to the muscles.
  • The incision is placed over the hip
  • The hospital stay is shortened.
  • Quick healing of the surgery.


Every surgery has its own set of risks and benefits.

  • Blood loss
  • Infection after surgery
  • Nerve injury
  • Fractures
  • Blood clots

Minimally invasive hip replacement is more time-consuming than traditional hip replacement surgery. People of different age, sex, body weight and other factors react differently to different surgeries.


  • Minimally invasive hip replacement surgery allows early discharge from the hospital.
  • The after- surgery is less painful, as small and less incisions are made.
  • Quicker return to normal routine.
  • Smaller scars
  • Lesser restrictions post-surgery.
  • Reduces surgical trauma
  • Cost-effective


With minimally invasive hip replacement, people can move within few days of surgery. The post-operative pain is much lesser. However, precautions have to be taken since the tissue takes time to heal. The non-cemented implants need time to bond to the patients bone. Tissues receive less trauma and hence, the time to heal will also be shorter. Restrictions are only for the first few weeks. The person may recover and take to routine activities soon.
