A new technique of knee replacement surgery was introduced in Gujarat recently by a team of doctors at Care Institute of Medical Sciences (CIMS) located in Sola. This new technique will enhance chances of the patient not needing another operation till at least 30 years. 

The new technique is called Visionaire - a patient-matched knee replacement surgery using Oxinium knee implants. Explaining the surgery, Dr Mark Snyder, of Good Samaritan Hospital, Ohio (USA) said, "Through this technique, a patient’s MRI and X-ray images are used to design and build surgical instruments which are customised for an individual’s unique knee anatomy."

The oxinium knee implants are made from ceramic zirconium oxide and reduce wear and tear of knee implants by nearly 40%-90% as compared to regular cobalt chrome-based knee implants, said Dr Snyder.

This has increased the cost of the surgery. Dr Amir Sanghavi, a trauma and joint replacement surgeon, said, "A regular knee replacement surgery will cost anywhere from Rs70,000-Rs75,000 however, with this Visionaire technique the cost of surgery touches Rs1.10 lakh."

Describing the advantages of this surgery, Dr Sanghavi continued, "With this technique, the surgery time will decrease by 50%. Also, in the case of regular surgeries the blood loss is from half to one litre but this technique will help minimise blood loss as there is no rod insertion and there is less tissue cutting.

The patient gets discharged on the third day from the hospital. Most important is that the patient will not suffer from any kind of infection in the future, as this jig will be used only for him or her."

The physiotherapy time required for patients undergoing knee replacement surgeries is also less in this technique. However, the patient after the MRI and X-ray has to wait for three weeks till the oxinium knee implants are produced in USA and sent back to India to be implanted.
