TOTAL KNEE REPLACEMENT
The most
common reason to replace a knee is arthritis resulting in pain,
stiffness,  deformity
or instability which interferes with your lifestyle and is not controlled
with simpler measures, such as medication, using a cane, or less
extensive surgery such as arthroscopy. A normal knee joint has smooth
cartilage surface which glide across one another with almost no
friction. In an arthritic knee, the joint surfaces are rough and
irregular, causing pain as the uneven surfaces grind across each
other. In a knee replacement operation, the rough surfaces are replaced
with smooth, gliding components and the deformities and stiffness
are corrected.
 Most
commonly, the surgeon enters the knee through an incision centered
over the front of the joint. The capsule of the knee is opened generally
on the inside edge of the kneecap. The muscles and tendons are then
pulled out of the way and the knee is bent to expose the arthritic
bone ends. Two to three millimeters of bone are removed from the
ends of both the tibia and the femur, which are shaped to accept
the implants. The metal implants are anchored to the tibia and femur,
using bone cement or a press fit technique. The technique of fixation
depends on many factors, such as the strength and quality of your
bone. A plastic implant is attached to the tibial implant to form
a firm, stable, low friction articulation between metal and plastic.
It is common to find considerable damage to the joint surface of
the kneecap requiring it to be resurfaced as well. At surgery, great
care is taken to restore the overall alignment of the knee and the
position and function of the kneecap
TOTAL HIP REPLACEMENT
Gradual deterioration  of
cartilage that occurs in osteoarthritis is the most common reason
for hip replacement surgery. Implanting an artificial joint eliminates
pain and restores near-normal movement. It is done for patients
suffering from arthritis. Hip replacement implant has the same parts
as your own hip-a smooth ball of special metal is inserted with
a stem with the bone canal, a cup of special plastic replaces the
worn-out socket. Most commonly the implants are cemented like a
special glue, in the young patients, some times non-cemented implants
are being tried  but
no definite proof that non-cemented is superior. Patient starts
walking on the second day with walker, then with stick, putting
weight on the ground. Rest of the program is as in the knee.
Kajang Medical center Joint Replacement Center is headed by Dr Lopez
- Chief of Orthopaedics a who has had a rich experience expanding
over years Kajang Medical Center has all the facilities which are
mandatory for Joint Replacement surgeries to be undertaken. It is
supported by excellent
physiotherapy and occupational therapy staff.
