A medical mistake during routine knee surgery reportedly left a woman paralyzed. The woman's daughter-in-law shared the incident with Nexstar's WKRN.

The surgery took place at a hospital, where potassium was administered, apparently contributing to the paralysis. The daughter-in-law indicated that her mother-in-law is not the only person to have experienced such an outcome.

Further details about the incident are available from the source, including an interview with the daughter-in-law who reported the medical mistake.
