A city doctor and his team have successfully removed stones from both knees of a 71-year-old male patient. Due to the deformity of the bones, the doctor also performed knee replacement surgery. The hospital claims that this is the fourth case in India and the ninth in the world where stones have been removed from both knees.

Prahlad Pawar, 71, a resident of Pune, had been suffering from severe knee pain and progressively worsening leg deformity for nearly 10 years. He was barely able to walk due to the deformity and thus was brought to SL Raheja Hospital in Mahim. Dr  Siddharth M Shah, a consultant-orthopaedics and joint replacement surgeon at the hospital, explained that after multiple tests, the patient was diagnosed with Synovial osteochondromatosis, a rare condition. Involvement of both knees in this condition is even rarer. The patient had an extensive manifestation of the disease, with multiple large stones in and around the knee, as well as severe knee arthritis and a tibial bone defect.
