Q: What is osteoarthritis?
A. Often called wear-and-tear arthritis, osteoarthritis is one of the most common forms of arthritis. The disease causes a breakdown of the cartilage that cushions the hip joint. As the cartilage breaks down, the result is bone-against-bone friction, leading to pain, eventual loss of movement, and the gradual weakening of unused muscles.
Q. How do I know if I have osteoarthritis of the hip?
A. Make an appointment with an orthopaedic surgeon who will evaluate your individual condition.
  • X-rays will show if you have cartilage loss, abnormal change in bone density, or bony projections or erosions.
  • A blood test will be taken to rule out rheumatoid arthritis.
  • Your hip will be examined to evaluate range-of-motion and any deformities.
  • You will b asked to describe the pain in your hip and to provide your medical history — injuries, infections, ailments, and medications you are taking.
Q. What are the benefits of having the Zimmer MIS Mini-Incision hip replacement procedure?
A. Results vary from person to person (due to factors such as weight, bone structure, and adherence to postoperative rehabilitation). The minimally invasive technique may offer you significant advantages over traditional hip replacement, such as:
  • Smaller incision and scar — 21/2 to 31/2 inches,
  • instead of the 10-to 12-inch standard incision
  • Shorter hospital stay
  • Faster rehabilitation
These benefits may allow a faster return to work and daily activities.
Q. How do I know if I should have the Mini-Incision hip replacement procedure?
A. The new technique is not for everyone. Candidacy for the procedure is based on several anatomical factors that must be assessed by your orthopaedic surgeon, including extent and pattern of arthritis and bone structure. People with the following factors typically are not candidates for this procedure:
  • Obesity
  • Recent history of deep vein thrombosis (DVT)
  • Unstable medical conditions that may lead to a higher risk of complications
  • Prior hip replacement surgery on the same hip

MIS™ Mini-Incision Hip Procedure

Continuing to enjoy life as we get older is important to everyone. But for those individuals suffering from hip arthritis,giving up a cherished lifestyle often becomes a harsh reality. Even the simplest daily activities that many of us take for granted, like walking or sitting comfortably in a chair, can become a painful struggle.

Hip arthritis is a disabling condition that commonly affects patients over the age of 60. In a healthy hip, the movement of bending, straightening or rotating is absorbed by cartilage, allowing the hip ball to move freely in the socket. Over time, the cartilage can wear away or become damaged, causing the bones to rub against each other. This results in symptoms such as thigh pain that radiates to the knee, groin pain, unequal leg lengths, limping, muscle weakness, and stiffness around the hip.

The Zimmer MIS Posterior Hip Procedure is designed to preserve many of the posterior hipstructures so that rehabilitation can be faster. Among the potential benefits of this minimally invasive technique are:

  • A single incision
  • Less muscle and soft tissue trauma
  • Shorter hospital stay
  • Smaller scar

This procedure has a much smaller incision—2-1/2 to 3-1/2 inches instead of the 10- to 12-inch standard incision. Patients may be able to return to their daily lives within 4-6 weeks, as opposed to the 3-4 month recovery period that is common for a traditional hip surgery. Talk to your doctor about which procedure may be best for you.
