Knee replacement surgery is a surgical procedure performed by orthopedic surgeons to resurface a bad knee caused by a knee injury, wear and tear of the knee, or arthritis. During the surgery, a surgeon replaces the damaged cartilage and bone with a manmade joint.
Knee replacement surgery relieves knee pain and restores functionality to the knee joints of the patient. It is also known as knee arthroplasty and is one of the most common surgeries performed in Pakistan. Most patients who undergo knee replacement surgery are aged between 50 to 80 years.
If the pain in a person’s knees has become unbearable and they are having trouble walking, climbing stairs and getting in and out of chairs; then they need to schedule an appointment with an orthopedic surgeon, who will assess their knee to determine if it needs to be replaced or not.
Their assessment will be based on the patient’s knee’s range of stability, motion, and strength. The doctor will also get an x-ray performed to determine the level of damage that their knee is suffering from. Then they will choose a surgical technique considering the patient's age, weight, overall health, activity level as well as the shape and size of their knee.
Preparing for knee replacement surgery is no different from preparing for any other surgical procedure. Patients will have to stop taking certain medications and dietary supplements before their surgery according to the instructions of their anaesthesiologist and orthopedic surgeon.

They will also be needing assistance with everyday tasks like cooking,bathing and laundry after the surgery so they should make sure that they arrange househelp or someone to stay with them beforehand.

Knee replacement surgery usually takes around two hours to complete. Then the patient is shifted to a recovery room for one to two hours or until they are conscious enough to recognize their surroundings. After this, they are shifted to a hospital room where they stay for a couple of days. During that period pain control medications are prescribed to them by the surgeon.
The day after the surgery a physical therapist teaches the patient how to exercise their new knee. Patients are encouraged to move the foot and ankle and do breathing exercises which in turn help in preventing swelling and blood clots, by increasing blood flow to the leg muscles.
Some patients also receive blood thinners or compression boots to prevent swelling and clotting. Patients are advised to continue physical therapy at home or a center to make recovery quick and easy.
