My cartilage has totally degenerated due to arthritis: Saina Nehwal on retiring at 35

While confirming her retirement from competitive badminton, Olympic bronze medal-winning player Saina Nehwal said her cartilage has totally degenerated due to arthritis. "My knee was giving up in one or two hours. It was swelling and it became very tough to push after that," said the 35-year-old. Saina hadn't played a competitive match since the 2023 Singapore Open.
