Step By Step Guide For Total Knee Replacement Surgery India

Step 1: Making you rest

The anesthetist shall give you either general or spinal anesthesia to make you fall asleep during the procedure.

Step 2: Incising the knee

The surgeon shall make an incision over the anterior part of your knee which allows easy access to the patella often known as the kneecap. The incision is typically about 8-10 inches in length in the case of traditional knee replacement surgery. In contrast, the incision is just 4-6 inches long assuming the surgery is being performed using a minimally invasive approach.

Step 3: Turning the Kneecap

After making an incision over the knee, the primary uncovered part is your patella. As the surgeon gains access to the patella, he rotates it outwards providing adequate space to perform the procedure.

Step 4: Preparation of Thighbone

The surgeon then resurfaces your thighbone medically known as the femur. After carefully exposing the knee joint, the surgeon utilizes specialized instruments to measure the bone and cut the damaged bone and cartilage from the base of the femur with the most extreme precision. The cut end is then resurfaced for appropriate fitting of the femoral component of the prosthesis.

Step 5: Fixing the Femoral component

As the femur is resurfaced, the surgeon fixes the femoral component made of metal or plastic to the base and fixes it into place using bone cement.

Step 6: Preparation of Shinbone

Shinbone also called Tibia is the following unresolved issue that resurfaced. The upper finish of the tibia is made liberated from damaged bone and cartilage and then it is reshaped to fit the tibial component of the artificial knee prosthesis.

Step 7: Fixing the Tibial component

The Tibial component (tibial tray) is then fixed to the upper resurfaced part of the tibia and is stuck in place using bone cement. As soon as the tray is fixed, the surgeon places a polyethene insert to gather between the femoral and tibial components that act as a cushion and offer help to your body while bending and flexing your knee.

Step 8: Re-tuning the Patella

The surgeon smoothens the lower surface of the patella and fixes it with the added plastic patellar component in request to confirm an appropriate fit with the remainder of the implant. Whenever required, the plastic component is cemented to the bone.

Step 9: Concluding the Procedure

The surgeon then checks for the legitimate alignment, working, sizing and positioning of the implant by bending and flexing the knee. After confirming, the surgeon stitches the incision and dresses it. The surgery takes approximately 2 hours to complete.
