Hans-Wilhelm Müller-Wohlfahrt (born 12 August 1942 in Leerhafe, today part of Wittmund, East Frisia) is the Germany national football team doctor and current club doctor of Bayern Munich.
He was a club doctor for the club between 1 April 1977 and 16 April 2015, and again since November 2017.
He resigned after the medical staff was blamed after a 3–1 loss to Porto in a UEFA Champions League match, and rejoined after the reappointment of Jupp Heynckes as coach.
Many of the German doctor's treatments are controversial, including using injections of a substance called Hyalart, extracted from the crest of cockerels, which is claimed to help lubricate knee injuries and take away the pain.
He has also injected Myo-Melcain, which is the painkiller Procaine in a honey solution, or Actovegin into patients' muscles.
Müller-Wohlfahrt's use of homeopathic medicine to treat players is also controversial.
