MIS QUAD-SPARING TOTAL KNEE REPLACEMENT
Total knee replacement is an advanced procedure performed for severe
damage of the knee joint. Total knee replacement is often referred
to as total knee arthroplasty, and involves resurfacing and replacing
damaged parts of the knee. Osteoarthritis is usually the cause of
the knee damage. Osteoarthritis causes knee pain with activity,
but pain can also occur at rest. It may be difficult to go up or
down stairs, walk long distances, or get up from low seats. There
may be swelling, stiffness, or the feeling of instability.
Minimally invasive total knee surgery (MIS) is a giant step forward
in performing knee replacement through a smaller incision. MIS quad-sparing
total knee replacement entirely spares the quadriceps muscle and
tendons, which control the bending of the knee. The splitting or
cutting of these tissues causes much of the pain during recovery.
Traditionally, knee replacement is done through an incision that
is 8" to 10" long. MIS knee arthroplasty involves performing
the surgery through an incision that is only 3" to 5"
long. Specialized instruments allow Dr. Penenberg to access the
damaged knee joint and place the implant through the smaller incision.
The actual resurfacing of the knee joint, and the implantation of
the prosthesis, are similar to the traditional technique. The smaller
incision and the muscle incision mean potentially less damage to
tissue around the knee, and less blood loss in surgery. This can
result in less swelling, and less pain after surgery, which can
result in faster healing, and accelerated progression in Physical
Therapy. Less blood loss can result in less time in the hospital,
and a faster return to work and activities.
Contraindication to using MIS technique would be severely obese patients.
REVISION TOTAL KNEE REPLACEMENT
Patients undergoing a total knee replacement will most likely never
need revision/repair surgery. If there is unusual wear and tear
on the prosthesis, or, an incident occurs that damages the bone(s),
or the prosthesis, a surgical repair may be necessary. Repairs may
be simple or complex. Not all orthopedic surgeons perform total
knee replacement revision surgery. The surgeon's experience with
revision surgery is important to a successful outcome.
Dr. Penenberg has extensive experience with knee revision surgery.
His experience includes surgical solutions for simple and complex
problems. A simple problem may be the replacement of the plastic
liner. A complex problem may be an infection requiring the removal
of the knee prosthesis, the placement of an antibiotic spacer, and
6 - 8 weeks of intravenous antibiotic therapy to eradicate the infection
before re-implanting a prosthesis.
Dr. Penenberg works with a team of specialists in infectious disease
management and internal medicine to plan a sophisticate course
