Michiel de Goede (the respondent) was a young rugby player with a five-year contract with the Sharks Rugby franchise junior team. On 5 April 2007, he sustained a ruptured patella tendon injury during a rugby match. He was initially treated at 1 Military Hospital where Dr Khwitshana misdiagnosed the injury as a sprained knee. Five days later, Dr Thiart at Unitas Hospital correctly diagnosed a patella tendon rupture. On 13 April 2007, Dr Kluever (first appellant), an orthopaedic surgeon employed by the SANDF at 1 Military Hospital, performed surgery to repair the ruptured patella tendon. After the operation, Michiel's leg was placed in a brace for six weeks. Following removal of the brace on 25 May 2007, he commenced physiotherapy with Mr du Plessis. Du Plessis struggled to restore full flexion. In September 2007, biokineticist Mr Liebel noticed the right patella was higher than the left. On 1 October 2007, Dr Bhawani (second appellant) removed the circulage wire. Despite ongoing rehabilitation, Michiel could not regain full knee function. In September 2008, Dr de Vlieg identified a 'high riding patella' and performed remedial VY quadriceps plasty surgery. He found the original repair still intact but the patella positioned too high, with irreversible damage. Michiel's rugby career ended. He sued the doctors for negligence, with the Minister of Defence (third appellant) to be held vicariously liable.
