Computer Navigation In Knee Replacement

Traditionally, the knee replacement surgeon utilizes specialized instruments (jigs) that are temporarily used during surgery to facilitate implant alignment and positioning. An experienced surgeon will be able to perform a successful knee replacement using these standard instruments. However, to further improve the accuracy of placement of implants, which directs affects the longevity of knee replacement, computer navigation may be utilised. This advanced technique of computer navigation is available and routinely used by Dr. Tanveer Singh Bhutani at Eva Hospital.

Computer navigation is a promising procedure that renders the knee replacement procedure more successful than in the past. In combination with new implant designs, technical expertise, and better understanding of knee ligaments and kinematics, computer navigation in knee replacement holds promise of greater longevity and better implant positioning than conventional techniques, contributing to higher patient satisfaction.

What is Computer Navigation?

Computer navigation is a procedure technique that offers effective guidance during a total knee replacement procedure. The advanced technique requires a combination of a computer, infrared cameras, and specialized instruments that project the exact extent of knee damage and the corrections that need to be done.

Technically, there is infrared sensor marking and mapping of the anatomy of the diseased knee and the adjacent bones, which are the femur and the tibia. Computer navigation Knee replacement in India has resulted in;

  • Greater and normal range of motion
  • Improved joint stability
  • Shorter periods of hospitalization
  • A quick recovery

The use of sophisticated software enables the surgeon to view the entire anatomy of the knee and ascertain the right position for the replacement. During the procedure, the surgeon cuts or trims the bones and balances the ligament in order to position the new artificial knee in the proper anatomic alignment.

As the software and the dimensional images of the anatomy of the knee are crucial, it is the surgeon’s capability of interpreting the retrieved information to render the procedure successful.

Advantages of the New Computer Navigation (CN) Approach

  • The new system eliminates the need for a rod, that is normally inserted into the intramedullary (IM) canal of the bone utilized for aligning cuts.
  • Tiny incisions- With the computer navigation system, the soft tissue dissection is kept less invasive under the computer navigation approach and the incisions are made smaller.
  • This approach facilitates complicated total knee replacement procedure such as where there is significant femur deformity or tibia.
  • The procedure is more precise, accurate and productive, however, Computer Navigation Knee Replacement Cost in India is considerably high for 70% of the patients. Also, the procedure requires more time compared to the conventional total knee replacement procedure.

Prevailing research indicates that computer navigation approaches for knee replacement are more precise for the patients. However, research also shows that there is significantly a low percentage of surgeons who conduct computer-assisted procedure since they require higher skills.
