Minimally Invasive Joint Replacement


You no longer have to live with severe joint pain and the physical limitations it causes. If medication and other conservative treatments have not provided adequate relief for your symptoms, MIS joint replacement is a strong option that may provide the pain relief you want and enable you to enjoy your favorite activities again.

Minimally Invasive Surgery has revolutionized many fields of medicine over the past 25 years. MIS uses specialized techniques and instrumentation that allow physicians to perform major surgery without a large incision. By this measure, MIS knee and hip joint replacement is “minimally invasive” as it requires only a small incision that minimizes soft-tissue trauma. Among the many benefits that MIS surgical techniques may offer include less pain, shortened time, and less scarring.

Revolutionary Ceramic Hip Replacement 

The Trident® Ceramic Acetabular System is an artificial hip replacement device built with a state-of-the-art ceramic-on-ceramic bearing couple. The replacement device has four basic components: an alumina ceramic insert (socket liner), an alumina ceramic femoral head (ball), a metal acetabular shell (socket), and a metal femoral stem (hip stem).

The device works as follows: the hip stem is inserted into the top of the thighbone and the ball fits onto the top of the hip stem. The socket liner and mating socket are then fixed to the hip joint so the ball and socket articulate together.

Less Wear Than Metal and Plastic

The bearing surfaces (ball and socket) of the Trident® implant are made of alumina ceramic. Laboratory testing of alumina ceramic show that it sustains less wear than the traditional metal and plastic materials used in total hip surgery. Alumina ceramic is extremely hard – second only to diamond – and provides excellent lubrication between the ball and socket. With these characteristics, laboratory testing of alumina ceramic-on-ceramic demonstrates significantly lower wear versus conventional metal-on-plastic components. Because of this, it is anticipated that alumina ceramic will extend the life of the implants. The Trident® Ceramic insert’s patented design makes it the strongest ceramic insert available on the market.

Computer-Assisted Total Knee Replacement

Total knee replacement (TKR) has been performed successfully in the U.S. for nearly four decades. Today there may be a significant advancement in this procedure using new advanced surgical computer technology to it even better.

TKR is an extremely successful way to treat patients suffering from severe knee pain. It restores function and helps patients return to normal activity. The new knee navigation system allows surgeons to make intra-operative adjustments to within a fraction of a degree, which ensures the greatest precision and most accurate fit for the prosthesis. This in turn can result in shorter hospitalizations with fewer complications, as well as improved stability and longevity of the prosthesis.

TKR is usually reserved for patients with severe arthritic conditions who are over 50 years, but the operation is being performed in younger patients thanks to new technology like the navigated total knee system.
