Also known as knee arthroplasty, a knee replacement surgery entails replacement of the weight bearing surfaces of the knee joint with metal and plastic components.
The surgery is commonly done in cases of severe knee arthritis such as osteoarthritis, rheumatoid arthritis and psoriatic arthritis. Some other conditions which cause disabling knee pain are — meniscal tears, cartilage defects and ligament tears.
There are many variations of knee replacement surgery the choice of which depends upon age of the patient, condition of the joint and patient’s requirement. The various forms of knee replacement are:
- Total Knee Replacement (TKR) — A total knee replacement is the surgery considered for treatment of arthritis when all other conservative treatments have not been able to relieve patient’s severe knee joint pain. It is commonly done in people above the age of 50.
Performed under general anaesthesia, the surgery takes about 2 — 3 hours. The surgery entails making an incision of 8 — 12 inches in front of the knee. The surgeon cuts the damaged bone and cartilage and replaces them with artificial joint made of high grade polymers.
The outcomes of total knee replacement are very gratifying. For a couple of weeks, you would be refrained from doing high impact activities such as jogging and jumping. After a TKR, you can enjoy an active lifestyle free of pain.
- Hi-flex knee replacement — Hi — flex knee replacement surgery is a boon for patients seeking increased function after knee replacement. It is also called full knee replacement as it allows bending up to 155 degrees.
The high flex movements allow activities like kneeling, squatting and gardening but the high degree of flexion is not achievable in all the patients. The candidates for hi flex knee replacement are those who have pre-operative knee bending above 90 degrees , do not have ankylosed or fused knees and even if they have rheumatoid arthritis, should not have much bone destruction.
The outcomes of hi-flex knee replacement are quite gratifying. It allows high degree of flexion while doing the activities like squatting (sit on the floor), kneeling, climbing stairs etc.
- Minimally Invasive (quadriceps sparing) knee replacement — It is a minimally invasive technique which allows the surgeons to insert knee replacement implants through a shorter incision. With this surgery, a smaller incision of about 3 — 4 inches is done which spares any kind of trauma to quadriceps muscles.
The results of this procedure are quite gratifying as one can perform all activities pain free and without any discomfort. Compared with traditional knee replacement surgery, this procedure causes minimal trauma, lesser blood loss, early recovery and shorter hospitalization.
- Partial knee replacement — This is an option for a small percentage of patients with osteoarthritis when the damage to the knee joint is limited to a small portion of the joint. In this procedure only the damaged portion is replaced with metal and plastic.
The outcomes of Partial knee replacement are quite satisfying. The pain is relieved and the patient has an active lifestyle after the surgery. In patients with unicompartmental arthritis, the partial knee replacement surgery delays performing a TKR for as long as fifteen years.
