Lenin is the first to do many pathbreaking orthopaedic surgeries in the country. A few to mention are , computer navigated minimally Invasive ( muscle sparing ) rotating platform knee replacement, transportal arthroscopic ACL reconstruction, Arthroscopic rotator cuff repair, Bankart repair with brachial plexus catheterization and Arthroscopic popliteal cyst decompression . He has created a benchmark in knee replacement with his minimally invasive subvastus ( muscle sparing ) rotating platform technique. This technique alleviates all the fear in the mind of patients and gives faster and full functional recovery with in a month. These rotating platform knees last for more than 20yrs and the best fact is patients never feel that the knee is artificial. He also rejuvenated the lives of many sports person and youngsters through his pioneering effect in arthroscopic surgeries of various joints. He established the department of arthroscopy and knee Surgery at MIOT over a decade and made it as a flagship department . Dr. LENIN then moved on to Apollo hospital, Greams Road, Chennai in the year 2009 and repeated the same feat. Over the last two decades he had been to all the continents in the world, and established these specialities in various hospitals inside and outside India. He has performed more than 20,000 joint replacements and arthroscopic surgeries of various joints which makes him a rare breed of surgeon with vast experience in both these specialities.

He noticed after open procedures, the joints took months and years to recover and full functional recovery was always questionable. Further more many sports personnel lost their carrier. At that point of time, key hole surgeries were well established in abdominal surgery but not in orthopaedics. Hip replacement was a common procedure but knee and shoulder replacements were not.
