RULE CHANGES TO REDUCE INJURIES IN THE AUSTRALIAN FOOTBALL LEAGUE John Orchard MD PhD FACSP FACSM FFSEM(UK) 2014 IOC Conference MONACO
Sports injuries are just injuries • There should be no fundamental difference between sports injury prevention and other forms of injury prevention. • Like other injuries, sports injuries have reversible risk factors which can be changed.
Knee PCL injuries – bigger but lesser • Can occur in sport with flexed knee hitting ground OR collision between players in mid-air (if player speed is fast enough). • Common in MCAs • Harder to reconstruct than ACLs but fortunately less likely to need it (although late patellofemoral overload)
PCL injuries in Aussie Rules • At start of game & after each goal, play commences with a ruck duel at centre bounce • PCL injuries increased over 1998-2004 as ruckmen started to increase length of run-up to aid jump
PCL injuries in Aussie Rules • Average of 3 PCL collision injuries in centre bounce ruck duels per year in AFL competition 1998-2004 • Reduced to less than one injury per year with centre circle rule limiting run-up of ruckmen.
AFL INJURY PREVENTION • Some (but little) resistance to (1) centre circle rule to prevent ruck PCL injuries (2) reduced head & neck contact to prevent these injuries • High resistance to restriction of interchange to reduce soft tissue injuries – coaches & sports science staff want to maintain high levels of control over rotations
