Knee Joint Replacement with CMI
Minimally Invasive Surgery
Over the past 25 years, minimally invasive surgery has revolutionized many fields of medicine. Its key feature is the use of specialized techniques and instruments that allow the doctor to perform major surgery without having to make a large incision. In this regard, MIS knee joint replacement is in fact “minimally invasive,” requiring only a small incision and possibly causing minor soft tissue trauma.
Total Knee Replacement (TKR) with CMI
Unlike conventional total knee replacement (TKR), which requires a large incision (8 to 12 inches) and significant disruption of the muscles and tendons, knee replacement CMI knee joint is done through a 3-to-4-inch incision. The amount of soft tissue (muscles and tendons, etc.) that is damaged during surgery can also be reduced compared to conventional techniques.
Partial Knee Resurfacing (PKR) with MIS Partial Knee Resurfacing (PKR)
is a minimally invasive procedure to relieve pain and disability in an arthritic knee. With partial knee resurfacing, only the damaged surface of the knee joint is replaced, potentially minimizing trauma to healthy bone and tissue. Partial knee resurfacing implants were developed with the needs of patients in mind. Because partial knee resurfacing implants are much smaller than total knee implants, the surgical incision may also be smaller.
Because fewer muscles and tendons are damaged with minimally invasive techniques, reconstruction is sometimes more natural, wound closure is easier, and recovery may be faster.
1 Clinical study have shown that the surgical approach to the femoral muscle used in MIS techniques results in less pain (both 8 days and 6 weeks after surgery) and a more rapid return to strength and muscle control.
2 It can take several months for a person to recover from the large incision and muscle damage that
Knee Joint Replacement with CMI (Continued)
with MIS The MIS knee joint replacement technique is less invasive than conventional total knee replacement, but it is still major surgery. Little additional time is required to perform it and it may have advantages for the patient.
Like any major surgical procedure, patients undergoing total joint replacement are at risk for certain complications, the vast majority of which can be avoided or successfully treated. In fact, the rate of complications after joint replacement surgery is very low. Serious complications, such as joint infection, occur in less than 2% of patients.
(In addition to the possibility of infection, other complications include blood clots, lung congestion, or pneumonia.) The risks that are normally present in conventional knee joint replacement remain.
You Don’t Have to Live with Acute Knee Pain
You don’t have to live with acute knee pain and its limitations on your activities. If you have not experienced adequate relief with medications and other traditional treatments, MIS knee joint replacement can bring relief from pain and allow you to return to your favorite activities.
A Great Step Forward in Knee Replacement
Minimally invasive knee joint replacement is a huge step forward in knee replacement for a number of reasons, which may include shorter hospital stay, less blood loss 1 and possibly less scarring.
