Total Knee Replacement

Knee pain and arthritis and stiffness is treated with a variety of methods. This includes medications, physical therapy and exercises, weight loss methods and surgery to replace the worn out cushions between the joint spaces. 

It is when all other medications and therapies fail that patient may consider a Total Knee Replacement or TKR. This involves replacement of the worn out joint with artificial prosthetic joint. 

This operation is usually performed under general anesthesia wherein patient will be rendered unconscious during the operative procedure. This operation can also be done under spinal or epidural anesthesia. A cuff like tourniquet is placed on the thighs just before the incision. When inflated this aids in reducing the blood flow to the operative site and reduces the risk of bleeding.  

There are basically two approaches to a TKR :

• One is the classical method 
• Another is the newly developed Minimally Invasive Surgery (MIS)

Procedure of classical approach to TKR:

• In classical TKR an eight to twelve inch incision is made in the front or side of the knee. 
• The muscles are cut open and the joint cavity is exposed. 
• The damaged parts of the joint including the lower part of the femur, upper part of the tibia are removed or sawed off.  
• The prosthesis or the artificial joint is a metallic or plastic replica of the lower part of the thigh bone and upper part of the tibia. 
• The new implants are sealed on the sawed off edges with the help of bone cement. 
• Some implants are uncemented. These can be set over the edges of the sawed off bones in a press fit system. 
• Prosthetic cartilage is placed between the prosthetic ends of the femur and tibia. 

Procedure of minimally invasive TKR surgery:

• Minimally invasive surgery as the name suggests involves a smaller incision of three to five inches. 
• Here the surgeon works the implant through a smaller opening. 
• This leads to less pain and more rapid recovery. 
• TKR  is a very successful surgery and with proper accompanying physical therapy it can provide much relief. This mimics the original joint and allows a free movement of the joint. Benefits of this operation are remarkable in terms of freedom from pain, improved range of movement of the knees, improved sleep and better quality of living. 

Total Hip Replacement

Total Hip Replacement (THR) is necessary when none of the other methods to correct a damaged hip is effective. In this operation the surgeon replaces the ball and the socket with metallic replacements and the cartilage with artificial joint material. Usually THR is done under general anesthesia, it can be also performed under spinal or epidural anesthesia where the anesthetic medicine is injected into a space between the vertebrae in order to numb the legs during the operation without making one lose consciousness. 

• During the operation an incision will be made on the affected hip joint and the affected portions of the hip bone and the femur will be sawed off.
• The new prosthetic parts will be attached to the bone with the use of bone cement. Once both the ball and the socket are in placed the damage cartilage is also replaced between the prosthetics. A test motion is usually done to check the proper placement of the prosthetics.
• You may need a blood transfusion at this stage if you have lost a lot of blood during the operation. A drain may be put to drain off the excess fluids from the operative site. 
• The muscles and skin are then sutured back using sutures or staples. The wound is bandaged.

After the surgery you will be transferred to the bed with a splint to hold the joint in place and avoid immediate movement. You will have to stay in bed with a wedge shaped cushion to keep the hip joint in alignment. Fluids, pain relievers and antibiotics may be given intravenously for a day or two before you can start on a normal diet and take the medications orally.

Early physiotherapy ensures early mobility and rapid recovery. Within a day or two you will be encouraged to walk with the help of crutches, walker or a cane. You may be released from the hospital in a few days to a week.

The benefits offered by this operation are remarkable in terms of reduction of pain and thus improvement of sleep, improvement of range of motion, physical capabilities and quality of life.
