CompLIT knee stands for Computer Assisted Less Invasive Total Knee Replacement. It is a novel technique of Knee joint replacement developed by Dr Sanket Diwanji ; using most advanced Computer Navigation system from Stryker- NAV 3. This is the first of its kind and the only navigation system in entire Gujarat.
The success of knee replacement depends up on restoration of limb alignment and balancing of ligaments. Studies have proven that postoperative mal-alignment of more than 4 degrees are associated with prolonged and incomplete recovery, persistent pain, poor range of motion, early failures and overall patient dissatisfaction. In conventional TKR surgeons rely on eye balling to restore limb alignment and fail to achieve desired result in as much as 20% cases.
Computer Navigation works like a satellite navigation system. Here, infra-red trackers are attached to patients' bone, which communicate with camera, which in turn transmit details of patient anatomy to a computer. Here, a 3D model of patient’s knee is created and displayed on screen. Surgeon can plan orientation and thickness of various cuts and execute the steps. The computer gives real time feedback regarding alignment, gap balancing, range of motion and correction of deformity. This data is stored in computer for future reference.
In conventional knee-replacement procedures, a long rod is inserted in femur (the bone above the knee) to determine proper alignment of the artificial joint, and surgeons must drill holes in the bones to position cutting tools. Computer navigation cutting devices that are positioned mechanically with computer assistance eliminate all that, making the procedure truly minimally-invasive and reducing the risk of infection and emboli while maintaining the highest level of accuracy.
Satisfactory restoration of limb alignment and ligament balancing leads to superior pain relief and early mobilization in postoperative period. Requirement of painful physical therapy is eliminated and patient can walk on the same day or next morning.
Stryker NAV 3 is most advanced optical navigation technology with proven accuracy. The system can be operated by surgeon without violation of sterile field. The Precision software provides smooth workflow, starting from preoperative deformity and range of motion to final alignment, range of motion and stability parameters.
