Total Knee Replacement - What To Expect?

Movement of the human body is possible through various joints which work in coordination to allow for smooth painless movement. However, with age, these muscles and tendons undergo wear and tear which gradually leads to tender swollen joints and painful movement.

The knee is the largest human joint and most of the body movements (walking, running, squatting, sitting, etc.) are only possible because of the flexible knee cap. Whether with age or with injury or trauma, if the knee is affected, then total knee replacement (TKR) would be required.

Indications: With a success rate of almost 98%, knee replacement almost seems magical for arthritis patients.

Wear and tear of the knee leading to arthritis. This causes all knee movements to be painful, which can be especially distressing at night.
Injury or trauma where the knee joint is damaged beyond repair.

What to expect during surgery?

1. Once it is decided that surgery is required, the doctor will brief you on what to expect before, during, and after the surgery.
2. The operation is done under combined signal epidural anaesthesia, so 3 days admission is required in the hospital.
3. The damaged portion of the knee is removed and this is replaced with an implant which is made up of titanium and cobalt chromium.
4. Hospital stay can vary from 3 to 5 days depending on overall condition of the person.
5. Most patients will be able to do basic movement on the very next day of the surgery.
6. Ice pack and painkillers can be applied to control swelling.
7. The pain will be completely gone within 15 days.
8. In the beginning, walking with the support of parallel bars is advised (walker). This can be followed by the use of cane for the first few days to avoid overload and damage to the knees.
9. Most people can walk the next day, though it is advisable to use a cane for the first few weeks so that knee can strengthen to support the load.
10. Regular postoperative visits should be scheduled for up to 2 months after surgery.
11. In addition, it is extremely important to draw up an exercise regimen and follow it to sustain and improve mobility.
12. In the absence of regular exercise, there could be stiffness of the joint which can set in and further aggravate the situation
13. Driving is permissible only after the doctor's advice.

Let your doctor know before going for any surgical procedure (including dental work) as people with TKR should have antibiotic coverage before any procedure.
