Knee replacement, is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve pain and disability. It is most commonly performed for osteoarthritis, and also for other knee diseases such as rheumatoid arthritis and psoriatic arthritis. In patients with severe deformity from advanced rheumatoid arthritis, trauma, or long-standing osteoarthritis, the surgery may be more complicated and carry higher risk. Osteoporosis does not typically cause knee pain, deformity, or inflammation and is not a reason to perform knee replacement surgery in Noida
Knee replacement surgery can be performed by the best knee replacement surgeon in Noida as a partial or a total knee replacement. In general, the surgery consists of replacing the diseased or damaged joint surfaces of the knee with metal and plastic components shaped to allow continued motion of the knee.
Pre-operative preparation
The patient is to perform range of motion exercises and hip, knee and
ankle strengthening as directed daily. Before the surgery is performed,
pre-operative tests are done: usually a complete blood count, electrolytes, APTT and PT to measure blood clotting, chest X-rays, ECG, and
blood cross-matching for
possible transfusion.
About a month before the surgery, the patient may be prescribed
supplemental iron to boost the hemoglobin in their blood system. Accurate
X-rays of the affected knee are needed to measure the size of components which
will be needed.
Medications such as warfarin and aspirin will be stopped some days
before surgery to reduce the amount of bleeding. Patients may be admitted on
the day of surgery if the pre-op work-up is done in the pre-anesthetic clinic or may come into hospital one or more days before
surgery.
Preoperative education is currently an important part of patient care.
There is some evidence that it may slightly reduce anxiety before knee replacement surgery, with low risk of detrimental effects.
Post-operative rehabilitation
The length of
post-operative hospitalization is 5 days on average depending on the health
status of the patient and the amount of support available outside the hospital
setting. Protected weight bearing on crutches or a walker is required until specified by
the surgeon because of weakness in the quadriceps muscle. In the immediate
post-operative period, up to 39% of knee replacement patients experience
inadequate pain control.
Your doctor will instruct you on what to do in the few days before
surgery and after surgery, so it becomes important to
consult the best doctor.
