Need To Know About Knee Replacement ?

Pain and deformity limiting your activities then Knee replacement can be a solution..!!!


Total knee replacement surgery is to relieve pain and restore the alignment and function of your knee. When a person is having intolerable pain, difficulty and pain in walking, limited mobilization or simply difficulty in get in & out of a chair. You have tried all sorts of medicine, injection and physiotherapy but nothing seems to work.

Who Need Knee Replacement Surgery:

pain & difficulty in walking  are  the main reason to go for knee replacement surgery. No matter what your age, if you have chronic pain in your knee & difficulty in walking, you may benefit from a total knee replacement surgery. As long as you are healthy enough to have surgery, there is no reason to continue living with pain. It is never too soon or too late to seek treatment that could provide you freedom from pain.

Purpose:  Total knee replacement is a lifestyle change surgery it’s never a emergency procedure. Total knee replacement is always a elective procedure. The purpose of total knee replacement surgery is to relieve pain and restore the alignment and function of your knee. The knee is made up of the femur (thigh bone), the tibia (shin bone), and patella (kneecap) .The surgery is performed under spinal, epidural or general anesthesia.  

Myths of TKR:

Obesity: Several patients think that knee replacement surgery is very risky for obese patient and results are not good in them. The truth is if understand the procedure, the physiotherapy and the do’s & don’ts then knee replacement is similar to thin person in obese person.

Surgery is Painful: It’s a big myth about the surgery. Yes in past knee replacement was considered to be very painful surgery. But now days with modern surgical procedure, better pain blocks, early mobilization & physiotherapy we can have knee replacement done without any fear of pain & discomfort.

Activity is not same as before: this is completely a false statement to make as knee replacement is done only to increase the activities, mobility & lifestyle change. If properly done in a good centre with excellent pre & post operative physiotherapy all patients can do lot better than past. There is no limitation for walking, climbing stairs, sitting in low chairs, catching public transport. Many of today’s patients can kneel, squat & sit crossed leg after knee replacement. Virtually there is no limitation to activities after knee replacement.

Its only for Elderly: the ideal age for the surgery is between 58yrs to 70 years. But virtually there is no limitation to the age. Now day’s younger patients with severe damage to knee joint are undergoing the procedure and their demands are high with good results. About 90% of patients undergoing knee replacement surgeries are above the age of 60 due to age related wear and tear.

Exercise and Healthy Diet Is Sufficient to avoid knee replacement:  yes its true that with regular exercise we can avoid knee replacement but we have to start at a very early stage when the arthritis is subclinical. Wear and tear usually starts from age of 35- 40 yrs. If we start exercise & healthy diet at this age we may skip knee replacement. But unfortunately we start everything once advance arthritis is already set in when knee wear & tear is so much that only knee replacement will help you.

TKR Is A repetitive Process: If TKR is done in patients above 55years the chances of re-surgery is rare. So virtually is someone is above 55yrs he or she will 99% never need a re-surgery provided the surgery is done properly.

Success Rate: knee replacement is a very successful surgery. Knee replacement provides pain relief, improved mobility and a better quality of life. Three to six weeks after surgery, you generally can resume most daily activities. Around four weeks if you can bend your knee far enough to sit in a car and if you have enough muscle control to operate the brakes and after you've recovered, you can do lots  of  low-impact activities, such as walking, swimming, golfing or biking. But you should avoid higher impact activities — such as jogging, skiing, tennis and sports that involve contact or jumping. Consult to your doctor about your limitations.

Rehabilitation begins immediately following the surgery. A physical therapist will teach you specific exercises to strengthen your leg and restore knee movement.

Dr.Debashish advised to our patient after knee replacement surgery for physical therapy exercises to strengthen the muscles around the new knee.  These exercises:

  • Increase muscle flexibility and strength, which helps protect the new knee and other joints
  • Promote healing by increasing blood flow

Below are knee-strengthening exercises that doctors and physical therapists commonly recommended to knee replacement patients.

Patients may be advised to do 10 or 15 repetitions of each exercise a few times a day. About 6 weeks after surgery, most patients are able to scale back and do exercises 3 or 4 times a week.
