Hip and Knee Replacement

Hip replacement is a surgical procedure -- performed in the US since the 1960s -- in which a diseased or damaged joint is replaced with an artificial joint called a prosthesis. Made of metal alloys and high-grade plastics (which are intended to mimic the function of bone and cartilage, respectively), the prosthesis is designed to move just like a healthy human joint. Over the years, hip replacement techniques and instrumentation have undergone countless improvements. Today, hip replacement is one of the safest and most successful types of major surgery; in well over 90% of cases it is complication-free and results in significant pain relief and restoration of mobility.2

Over the past 25 years, minimally invasive surgery has revolutionized many fields of medicine. Its key characteristic is that it uses specialized techniques and instrumentation that enable the physician to perform major surgery without a large incision. In this respect, MIS Hip Joint Replacement is indeed “minimally invasive,” requiring smaller incisions and potentially causing less trauma to the soft tissues than traditional techniques may cause.

MIS Hip Joint Replacement is less invasive than conventional Total Hip Replacement, but it is still a major surgery. It takes little additional time to complete and may result in advantages for the patient.

As with any major surgical procedure, patients who undergo total joint replacement are at risk for certain complications, the vast majority of which can be successfully avoided or treated. In fact, the complication rate following joint replacement surgery is very low. Serious complications, such as joint infection, occur in less than 2% of patients.4 (Besides infection, possible complications include blood clots, lung congestion, or pneumonia.) The risks normally encountered in conventional hip joint replacement remain.

Minimally Invasive Surgery (MIS) Hip Joint Replacement

MIS Hip Joint Replacement is an advancement in hip replacement that offers potential important advantages over standard surgical procedures.

Potential Advantages

An MIS hip replacement procedure replaces the joint with a prosthesis, but requires an incision that is only 3 to 4 inches long. The procedure does not disturb as many muscles and tendons in the hip area as the classic total hip procedure.1 This allows for a potentially more natural reconstruction after the prosthesis is in place and the potential for a quicker return to normal function and activity.1,3

The smaller incision and reduced muscle disruption indicate that patients may have a shorter recovery time and less scarring. With MIS hip replacement, there may be less blood loss, less time in surgery, and possibly a shorter hospital stay.1,3

Minimally Invasive Surgery (MIS) Knee Joint Replacement

Unlike conventional TKR, which requires a large incision (8 to 12 inches) and significant disruption of the muscles and tendons, MIS Knee Joint Replacement is performed through a 3 to 4 inch incision. The amount of soft tissue (muscles and tendons, etc.) that is disrupted during surgery may also be reduced compared with conventional techniques.

Partial Knee Resurfacing (PKR) is a minimally invasive procedure for relieving arthritic knee pain and disability. With PKR, only the damaged surface of the knee joint is resurfaced, potentially minimizing trauma to healthy bone and tissue. PKR implants were developed with patient needs in mind. Because the PKR implants are so much smaller than total knee implants, the surgical incision can be smaller as well.

Because fewer muscles and tendons are disturbed with the minimally invasive techniques, their reconstruction is often more natural, wound closure is easier, and recovery may be faster.5 Clinical studies have shown that the midvastus surgical approach used in the MIS technique results in less pain (at both 8 days and 6 weeks after surgery) and quicker restoration of muscle control and strength.6 It may take several months to recover from the large incision and muscle disruption that accompanies the standard approach.5
