Mr M was only 17 when he underwent successful anterior cruciate ligament (ACL) reconstruction surgery. Several days later he reattended the hospital as he was concerned about redness around the knee, difficulty in bending it and generally feeling unwell. Infection was suspected and swabs obtained. Despite the suspicion of infection, and swabs yielding positive results, the Claimant was not contacted. He returned to hospital 2 weeks later with septic arthritis. He underwent 6 washout procedures of the knee under general anaesthetic and the ACL graft had to be removed. He is likely to require a knee replacement in middle age as well as further surgery for further ACL grafting. He received £130,000.
