• First kind of Knee Surgery Developed by AIIMS Doctor to Treat Osteoarthritis

    Press Trust of India, New Delhi, 26 August, 2016.

    Dr. Rajesh Malhotra, HOD, Orthopedic Department, AIIMS (New Delhi) for the first time developed a new technique of surgery for the treatment of Osteoarthritis.

    During knee replacement surgery, damaged bone and cartilage is resurfaced with metal and plastic components. In uni-compartmental knee replacement (also called “partial” knee replacement) only a portion of the knee is resurfaced. This procedure is an alternative to total knee replacement for patients whose disease is limited to just one area of the knee.

    The Knee is composed of three compartments namely:

    • Medial Compartment
    • Lateral Compartment
    • Patello-femoral Compartment

    The new technique developed by Dr. Malhotra aimed at addressing Osteoarthritis by operating only on the inside compartment of a knee. The surgery was performed using fast track Unicondylar Knee Replacement procedure using Computer navigation technology.

    This Unicondylar Knee Replacement Surgery was developed to address Osteoarthritis specific to medial (inside compartment of the knee). Its advantage is that it leaves the healthy compartment of the knee area preserved treating only unhealthy compartments of the knee. So, if the patient is undergoing Osteoarthritis surgery, now patient has to only undergo surgery of unhealthy compartment of the knee i.e. partial knee replacement of knee.

    This Unicondylar Knee System developed is an implant design that is complete copy knee anatomy, hence natural motion of patients knee persists. This new technique of surgery developed will pave a new ray of hope for osteoarthritis patient who undergoes a painful knee replacement surgery. This will also reduce the pain experienced by the Osteoarthritis after Total knee replacement.
