Knee replacement surgery also known as knee arthroplasty is a surgical method of replacing the damaged parts of your knee with artificial parts. Knee replacement surgery is most commonly done for osteoarthritis, rheumatoid arthritis, and psoriatic arthritis.
Other major reasons for debilitating pain include meniscus tear, cartilage defects, and ligament tears. Elderly people usually have debilitating pain from osteoarthritis.
Knee replacement surgery consists of two types namely partial or a total knee replacement.
Generally, this surgery consists of replacing the diseased or damaged joint surfaces of the knee with artificial parts like metal and plastic components that are shaped in such a way that it allows continued motion of the knee.
A vast majority of people who have undergone knee replacement surgery see a huge improvement in pain and their ability to get around.
Knee replacement surgery involves a considerable amount of postoperative pain for which you have to undergo vigorous physical rehabilitation. The period of recovery maybe 12 weeks or longer and during this period you have to make use of mobility aids namely canes, crutches, and walking frames so that the patient can return to preoperative mobility.
It is said that approximately 82% of total knee replacements will last 25 years.
The physicians may advise you to undergo surgery for a number of reasons.
- If you are suffering from severe pain and stiffness and it is difficult for you to walk, get out of the chair, or climb stairs.
- If you have nagging knee pain even while you are resting and thus preventing you from sleeping well.
- If your knee gets swollen frequently.
- If physical therapy and medications do not help any longer to control the pain.
Before you undergo surgery, your surgeon will examine you and take your medical history. This physical examination will consist of X-rays and blood tests. From the X-rays, the doctor will be able to assess the degree of damage. The doctor will also figure out the movement of the joint and the strength of the muscles around the knees.
Similar to other surgeries inform your doctor if you are on any medications like blood thinners, aspirin, or other drugs. Also tell the doctor if you have a history of infections, bleeding, or blood clots. You shouldn’t take food for 8 hours before the surgery.
Knee replacement surgery has become more common and advanced these days.
If yoU are healthy the surgery will be done as an outpatient procedure without a hospital stay. Otherwise, you will have to stay in the hospital for at least 1 to 4 days.
Just prior to surgery, an intravenous line (IV) might be inserted into a vein in your arm or hand to give you fluids and medicines. They will also shave your skin where the doctor will make the cut.
You will be given general anesthesia to put you in a deep sleep during the surgery.
Surgery can take 1 to 2 hours. The surgery can be carried out in two ways. Firstly, the doctor might make an 8-to 10-inch cut in the front of the knee. Then they will remove the damaged part of the joint and the surfaces of the thigh and shin bone next to the joint. Having done this, the surgeon will implant the artificial knee.
Another method is called “minimally invasive” surgery. In this case, the doctor will make a shorter incision around 4 to 6 inches. This will cause less damage to the muscle and tendon. This procedure is done for a patient who is thin, young, and healthy.
You can be on your feet within a day, but you may not be able to do it on your own at first. So you may need a walker, a cane, crutches or parallel bars to get up.
Within a month you can expect a good improvement in flexibility and much less pain within a month. It is important to exercise your knee frequently to strengthen your muscles and to lower down swelling.
You will also need to take help from a physical therapist and go through a series of exercises to strengthen your repaired knee.
