Sports medicine doctor casts doubt on McGregor pre-fight injury theories
"I don't think so in his case, to be completely honest. I think there is certainly some kind of long-term side effects, you know, if these performance-enhancing substances, whatever it may be, are used incorrectly or used for too long, you can definitely have subsequent effects on the tissue. I think when it comes to the actual ligaments like the ACL, the meniscus, I would have a hard time drawing a direct correlation between the two."
About this episode
Sports journalist Ariel Helwani interviews Dr. Brian Sutterer, a sports medicine specialist with 1.5 million YouTube subscribers, to analyze Conor McGregor's knee injury sustained during a fight in Las Vegas over the weekend. The interview was conducted under makeshift technical conditions, with Helwani noting they were covering the fight outside their usual studio. Dr. Sutterer provides detailed medical analysis of the injury, initially suspecting an ACL tear based on the mechanism of injury but expressing cautious optimism after reviewing frame-by-frame replays that showed no clear tibial shift, a telltale sign of ACL rupture. He suggests a meniscus tear as a more hopeful alternative diagnosis. The doctor addresses circulating conspiracy theories about pre-existing injuries, stating he is not convinced McGregor was significantly injured beforehand, though he acknowledges all fighters typically carry some bumps and bruises. Most notably, Sutterer dismisses theories linking performance-enhancing drug use to the injury, countering New York Times reporting on the subject. He explains that while PEDs can cause tendon problems when muscles outgrow tendon strength, he sees no direct correlation to ligament injuries like ACL or meniscus tears. Regarding recovery, the doctor explains McGregor faces a potentially harder rehabilitation than his previous broken leg injury, with ACL surgery requiring 10-12 months and extensive neuromuscular retraining, while a meniscus trim could see him fighting again before year's end. Despite McGregor's age of 39, Sutterer would not discourage him from returning to fighting after recovery.
Key takeaways
- Dr. Brian Sutterer dismisses theories that performance-enhancing drugs contributed to McGregor's knee injury, finding no direct correlation between PEDs and ligament damage despite New York Times reporting on substance use.
- The sports medicine specialist suspects meniscus tear rather than ACL rupture after reviewing fight footage frame-by-frame and finding no tibial shift characteristic of ACL injuries.
- McGregor faces potentially harder recovery from knee injury than his previous broken leg, with ACL reconstruction requiring 10-12 months versus meniscus trim allowing return before year end.
- Sutterer expresses skepticism about conspiracy theories claiming McGregor was significantly injured before the fight, though acknowledges all fighters carry some pre-existing damage.
- The doctor would not discourage 39-year-old McGregor from fighting again after recovery, citing athletes like Lindsey Vonn who returned from worse injuries.
- ACL rehabilitation involves extensive neuromuscular retraining that is more difficult than bone healing, making it a harder recovery despite appearing less gruesome than leg fracture.
- Meniscus surgery outcome depends on whether tissue can be repaired with sutures or must be trimmed, affecting both recovery timeline and long-term knee function.
