Total Knee Replacement Surgery
Thank you for opting to have your surgery done with us.
I hope that you are cognizant of the other methods of treatment of your problem which has been discussed with you by me, my staff and assistants in my clinic, in advance, at the time of your consultation, and I trust if you have had any queries, they have been answered.
Based on our discussions, we have determined the suggested plan of action as the best option under the circumstances, keeping in mind your requirements and our current expertise.
To help you understand the process, I am comparing it to taking a flight from Mumbai to a foreign destination.
Just like before a flight, you need passports, visa, ticket bookings, like-wise for the operation, you need to book a date for admission and a date and time for surgery.
Just like the visa process, we need to know that you are fit for surgery and therefore, you need to share your medical history with us, alongwith ALL the medication that you normally take including tablets such as Aspirin and Clopilet which are blood thinners and can cause bleeding at the time of surgery, and medication for Asthma (you may need more oxygen during the surgery) and Diabetes (if your blood sugars are high, then wound healing is very poor). All inputs by you help make us more prepared to help you.
Specific medication & conditions of the heart (ECG, 2D Echo), lungs (PFT/X-rays), liver and kidney etc., need to be known as various drugs can interact with these functions. The physical act of giving you anesthesia may require extra tests like specialized x-rays of your spine, CT or MRI screening of parts of your body, so that we are better prepared to tackle your spinal position during the process of the surgery.
Just like you have a security check before taking a flight, we need the Physician and the Anesthetist to look through these pre-operative medical reports and to examine you so that we may reduce the risks still further.
Just like in an aircraft before take-off, there is a safety drill in case of any risks, likewise, in any surgery we are taking RISKS but minimizing it by trying to cover as many events as we can.
Just as every landing at an airport, the pilot has to contend with cross-winds, haze, other flights, weather changes, quality of communication etc., similarly every surgical procedure is individualized, some are longer, some are shorter and there are multiple variables.
The OTC is like a ticket. Just like you pay for a ticket before your travel. The Hospital expects you to do an OTC (Operation Theatre Clearance) so that the hospital and you are both aware of the expected expenses. Against your paid ticket you get a boarding pass, likewise against an OTC, the institution permits you to be taken to the theatre for surgery. This is based on averages, but in your individual case the total expenses may be more if there are complications or emergency requirements which may or may not be related to the actual surgical procedure.
You need to be aware therefore that this is an estimate only based on an AVERAGE and is NOT a PACKAGE.
Recovery thereafter is a natural process, and we as doctors help nature help you, with medication, nursing, physiotherapy and other techniques required for your recovery. I reiterate that healing is a process dictated by nature, we only help in this. Just as nature has storms, weather changes, etc, recovery can sometimes in your individual cases be slower and therefore worrisome to you.
Such delays are also worrisome to us as individuals and as a team. The nurses, other staff and my team help the recovery process. Your concerns will be addressed.
Just like in the airline industry the cost of the ticket for travel supports the airline staff, the salaries, the fuel for the aircraft etc., for our team to successfully execute the whole process, there is staff in the hospital which is supported by the expenses incurred for your case, for administration, security, laundry, dining, meals, air-conditioning, water, catering etc.,
Like certain budget airlines offer cheaper fares and skeleton services many doctors and medical facilities will be able to offer you these at lesser rates. In our institutions we have overheads to ensure that checks and measures are carried out for your safety and these necessitate the charges quoted by us.
Just like in any travel there is an Economy class or Business Class or First class at different charges, helping you reach the same destination, similarly in the hospital there are various classes of admission with different levels of comfort, helping you attain the best results. My team’s training, experience, etc., should make this a smooth landing.
I hope this helps you understand the process and I really look forward to greeting you on the other side with every success in your case.

Total Knee Replacement Surgery
If you are considering knee surgery the following total knee replacement information might help you understand the procedure and implants better.
Your knees work hard during your daily routine, and arthritis of the knee or a knee injury can make it hard for you to perform normal tasks. If your injury or arthritis is severe, you may begin experience pain when you’re sitting down or trying to sleep.
Sometimes a total knee replacement is the only option for reducing pain and restoring a normal activity level. If your and your doctor decide a total knee replacement is right for you, the following information will give you an understanding about what to expect.
A total knee replacement involves cutting away the damaged bone of the knee joint and replacing it with a prosthesis. This “new joint” prevents the bones from rubbing together and provides a smooth knee joint.

In the total knee replacement procedure, each prosthesis is made up of four parts. The tibial component has two elements and replaces the top of the shin bone or tibia. This prosthesis is made up of a metal tray attached directly to the bone and a plastic spacer that provides the bearing surface.
The femoral component replaces the bottom of the thigh bone or femur. This component also replaces the groove where the patella, or kneecap, sits.
The patellar component replaces the surface of the knee cap, which rubs against the femur. The patella protects the joint, and the resurfaced patellar button will slide smoothly on the front of the joint.
Before you are taken to the operating room you’ll be given medication to help you relax, and the anesthesiologist will talk with you about the medications he’ll be using. In the operating room, you will be placed under full anesthesia.
Once you are “under” the surgeon will begin by making an incision in your leg to allow access to the knee joint. He’ll then expose the joint and place a cutting jig or template on the end of the femur, or thigh bone. This jig allows the surgeon to cut the bone precisely so that the prosthesis fits exactly. Once the femur is cut, the tibia is cut using another jig for proper alignment of the knee prosthesis. The undersurface of the patella is then removed.
Now it’s time to place the prosthesis. This begins with the femoral prosthesis, which is cemented in place using a special bone cement. Next the metal tray is attached to the top of the tibia. This will provide the weight-bearing surface of the femur. The plastic spacer is then attached to the metal tray. This will provide the weight-bearing surface of the femur. If this component should wear out while the rest of the artificial knee is sound, it can be replaced. This is known as a “revision.” Next the patellar button is cemented in place behind the knee cap. Finally, the incision is closed, a drain is put in, and the post-operative bandaging is applied.

You will be discharged when you can get out of bed on your own and walk with a walker or crutches, walk up and down three steps, bend your knee 90 degrees and straighten your knee.
At home you should begin ambulation with a cane as tolerated. Keep your incision clean and dry and watch closely for any signs of infection.
You’ll continue your home exercise program and go to outpatient physical therapy, where you will work on an advanced strengthening program and such programs as stationary cycling, walking, and aquatic therapy.
Your long-term rehabilitation goals are a range of motion from 100-120 degrees of knee flexion, mild or no pain with walking or other functional activities, and independence in all activities of daily living.
