Many of the German doctor's treatments are seen as controversial, including using injections of a substance called Hyalart,[4] 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.[citation needed]
Müller-Wohlfahrt's use of homeopathic medicine to treat players is also controversial.[5][6][7]
Darren Gough[16][17] and Alex Tudor,[17] Essex cricketers, have benefited from the German doctor's pioneering treatments. On 6 May 2009 it was announced that he was helping Akpo Sodje recover from a longstanding hamstring problem.
Rugby World Cup winner Will Greenwood[19] is another who has benefited from the doctor's treatment after 8 months with a groin problem. Weeks later he was staking a claim to a recall to the England team.
One of his more unusual treatments was when St Johnstone F.C. striker Peter MacDonald was prescribed goat's blood injections in a bid to cure a recurring hamstring problem.[21]
In 2010, he treated Bono (singer for U2) and Usain Bolt for severe back injury.[22]
In 2016 Usain Bolt devoted his 100m sprint gold medal at the 2016 Olympics in Rio to Müller-Wohlfahrt, who was at the stadium, after having received treatments from him for a previous calf injury.[23]
In 2019, he worked on Collingwood Magpie AFL Jordan De Goey in a bid to get his injured hamstring resolved in time to play in the AFL Grand Final if the team get through their penultimate match against the GWS Giants.[24]
