Avascular necrosis (AVN) or osteonecrosis - death of bone tissue due to a lack of blood supply - continues to be a cause of concern in patients post Covid-19 recovery. Doctors said there is an urgent need for more awareness on the judicious use of steroids which cause the complication, and early diagnosis.

A 24-year-old resident of Antop Hill recently underwent hip replacement after she was diagnosed with hip avascular necrosis. Aisha Khan is all set to return to work after a yearlong fight with Covid-19 and the complications that followed after recovery. She works as a lab technician in Khar and caught Covid-19 last year in April.
