Total Knee Replacement

Patients whose arthritis or knee condition is severe and affects the whole knee, a total knee replacement may be the most suitable procedure to relieve pain and maintain movement.

In total knee replacement, both inner and outer articular surfaces on the femur (thigh bone) and on the tibia (shin bone) are replaced.  The prosthesis (replacement components) include a replacement for the anterior cruciate ligament to help maintain normal knee function.  The operation may or may not include the patella (knee cap).

The operation usually involves four to five nights in hospital.  Using advanced, minimally invasive techniques, patients are often standing on the day following the operation and can begin physiotherapy immediately, with regular sessions each day.

Range of movement following a knee replacement is usually improved, but the operation is primarily performed to remove pain and maintain movement.  However, as pain can restrict movement before a replacement operation, patients often find the range of movement increases significantly.

Patients can improve the outcome from a knee replacement operation by starting physiotherapy before the operation.  This can improve movement, strengthen muscles and increase flexibility – all of which can lead to a faster and fuller recovery post surgery.
