When should you consider getting a Knee Replacement Surgery?
If your knee is severely damaged and deformed by arthritis or injury, it may be hard for you to perform simple activities such as walking or climbing stairs. You may even begin to feel pain while you are sitting or lying down. If medications, changing your activity level, and using walking supports are no longer helpful, you may want to consider total knee replacement surgery.
A knee replacement surgery should be considered if you have :
Most patients who undergo total knee replacement are age 60 to 80, but orthopaedic surgeons evaluate patients individually. Recommendations for knee replacement surgery are based on a patient's pain and disability, not age
Following total knee replacement, more than 90 of patients have no pain, or only slight pain, and their walking is no longer limited by their knee. Most patients can live a full and independent life.
The expected outcome of a total knee replacement are, in order of priority:
1. Pain relief
2. Standing and walking that is not limited by the knee
3. Improved knee motion
4. Improved knee strength
5. Correction of the deformed legs
Total knee replacement is major surgery, which usually involves a 3-4 day stay in the hospital followed by rehabilitation period of 2-3 months.

Can both knees be replaced together?
Minimally invasive Knee replacement surgery (MIS TKR) is a new method of performing Knee replacement using an incision that is half the length of the standard total knee incision.
This technique minimizes muscle cutting thereby reducing the post operative pain, allowing earlier rehabilitation and reducing the duration of hospital stay.
The knee components are same as those used during the traditional surgery but using special instrumentation only a 4 inch incision is sufficient to carry out the surgery. MIS Knee replacement is possible in majority of patients needing knee replacement, exceptions being large legs due to obesity and bulky muscles.
What is the usual postoperative recovery course after Knee replacement?
On 1st postoperative day, the leg is supported in a knee brace and one or two plastic tubes (drains) are placed to drain excess blood from the knee. The patient is given antibiotics, painkillers and a blood-thinning agent. The patient is made to sit up and walk with support the next day. The drains are removed after 24-48 hours. The patient is discharged 5-6 days after the standard TKR and 3-4 days after a MIS TKR operation. The sutures are removed between 10-14 days, and physiotherapy is started to regain knee function. Outpatient physiotherapy may be required for 3-6 weeks.
How much bend will I get after surgery?
Bending(Flexion) in the knee following Knee Replacement Surgery depend on varoius factors like pre surgery movement in the knees, weight of the patient and type of implants used. Patient with good movements before surgery and patients with lean, non-obese legs usually achieve greater bend in their knees following surgery. All other things being equal, High-flex implants allow increased bending in the knee joints (15-20 deg more) as compared to standard implants. Wth standard implants majoruty of patients will achieve 90-120 deg bending, however with Hi-flex implants patient can achieve 140 deg bending, This increased bending allows better functional abilities espectially in climbing stairs and getting in or out of a car.
