It's 7 am on a Sunday morning in December, and the air is fresh and crisp. Niranjana Mehta, 84, arrives at the Marine Drive promenade opposite the National Centre for the Performing Arts with her son Dr Hemant Mehta. This is the first time in over two months that she is going to walk outside her Nana Chowk home, and for long. In October, Mehta underwent hip hemiarthroplasty or partial hip-replacement surgery, a procedure where the femoral head commonly called 'the ball' of the damaged hip joint is replaced. Getting back on her feet hasn't been easy. Struggling with blood pressure, low haemoglobin and a cardiac issue, has made recovery challenging. She looks around for Dr Aashish Contractor, and breaks into a reassured smile when she spots him.

Dr Aashish Contractor takes a selfie with Niranjana Mehta, 84, who came out for a long walk for the first time after her partial hip replacement surgery, on Dec 3. His colleague Dr 'Y Bhamre is to the left
