Mumbai, India (PressExposure) October 30, 2010 -- Asian Heart Institute’s JIG in joint replacement

Recently Asian Orthopedic Institute, a new division of the Asian Heart Institute has got registered for a new technique in joint replacement making it one of the first few hospitals in India to be registered for this technique. This technique is known as the Patient Specific Jig. In this technique before the surgery pre operatively a CT scan is done. The CT scan is a 3D scan & once it is done the plate is sent to Johnson & Johnson Depuy, US. (J&J are the world leaders in manufacturing the joint replacement implants). Based on the plate a jig (cutting block) is created.

The J&J centre in the US in collaboration with the primary surgeon back home creates the jig for the knee which fits as a pressfit during surgery. These jigs are manufactured as per the patient’s anatomy & helps in the bony surgery to be more precise during surgery. Earlier in the conventional method these cutting blocks were more generic & were only of specific sizes. Hence during a surgery if the size was in between the standard sizes, the bony surgery would not be as accurate.

Moreover the accuracy of the blocks decreases over time. And now this technique is an added feature that the patients can opt for better results. According to Dr. Suraj Gurav, Orthopedic & Joint Replacement Consultant at Asian Orthopedic Institute- “The Patient Specific Jig is an advanced technique that reduces the surgical time, aiding in the speedy recovery of the patient.”

The other advantages of this technique are:

1. The jig is made according to the exact bony size of the knee
2. There is better mechanical alignment of the lower limb post surgery
3. High level of accuracy of the bony surgery
4. Size of the skin cut is reduced & hence recovery is faster
