Proposed modified classification system of the Munich Consensus Statement. Can the area of haemorrhagic effusion in muscle injuries be the dividing line between mild (3A) and moderate (3B) injuries?

Our study highlights how this distinction could be easily practiced by recognizing the presence of a haemorrhagic collection and how it predominates in determining a worsening of the prognosis and therefore an extension of the RTP. Hence, we can conclude that athletes who do not have blood collection, but only interstitial haemorrhage between fibres can be considered as type 3A, while athletes with interstitial haemorrhage at diagnosis can be considered as type 3B.
