What is Image Guided Surgery?
With computer assisted joint replacement surgery, a state-of-the-art computer that acts like a navigation system for the body calculates a three-dimensional representation of the patient's anatomy and transmits data continuously throughout the surgery. The process virtually ensures perfect implant positioning resulting in lower pain recovery. Surgeons can navigate through the surgical steps and verify both balancing and implant position before the surgery is complete, increasing the implant lifespan ultimately heightening patient satisfaction.


What is hip replacement?
A hip replacement is a combination of metal and plastic coverings for raw arthritic bone surfaces. They replace cartilage that has worn away.

Patients may benefit from hip replacement surgery if:

  • Hip pain limits everyday activities
  • Hip pain continues while resting
  • Stiffness in a hip limits the ability to move
  • Pain relief from anti-inflammatory drugs or glucosamine sulfate is minimal
  • Harmful or unpleasant side effects from hip medications are experienced
  • Other treatments such as physical therapy or the use of a gait aid such as a cane do not relieve hip pain


What is knee replacement?
A knee replacement consists of metal and plastic coverings for raw, arthritic bone ends surgically implanted to replace cartilage that has worn away.

Knee replacement surgery may be considered for patients when:

  • Severe knee pain limits everyday activities
  • Moderate or severe knee pain persists while resting
  • Chronic knee inflammation and swelling do not improve with rest or medications
  • Knee deformity exists: a bowing in or out of your knee
  • Knee stiffness persists: inability to bend and straighten your knee
  • Pain relief with non-steroidal anti-inflammatory drugs is nominal
  • Tolerance or complications from pain medications is an issue
  • Other treatments such as cortisone injections, physical therapy, or other surgeries show a lack of improvement
