Several weeks ago, our post “NFL ACL Epidemic –
Will This Season Be Any Different?” received a lot of activity and sparked some
interesting discussions & debate on our twitter feed. Although injuries are a part of any contact sport,
if there is something you can do to prevent or reduce the incidence of are we
not obligated to do that? Looking at the
number of reported non-contact ACL injuries last year in the NFL, by
conservative estimates, at least 66% of those were non-contact. Some authors and sports writers (2013: Year of
Injury) put non-contact ACL injuries in the 70-75% range. Why is that important? Because these are the preventable injuries!

When thinking of the individual player, this
has real long term consequences both for their future performance as well as
future earning potential. According to
the NFLPA the average length of an NFL player’s career is 3.3 years and
according to the NFL it is 6 years. Either
way, most players will try to maximize their earnings during this time
period. Most know that knee injuries and
specifically ACL injuries has a significant impact on performance and hence
future earning potential. This is why,
the NFLPA rated knee injuries as the number one concern among NFL players
during the 2013/14 season. But when you
look at the research to determine the impact on performance, the studies are really
inconclusive. In August 2014 issue of
the American Journal of Sports Medicine,
Aune et al looked
at Return
to Play After Partial Lateral Meniscectomy In National Football League Athletes. In this study, 61% of the 77 NFL players
undergoing partial lateral meniscectomies, were able to return to play at his
previous level of competition. The average
length of time to return to play was 8.5 months. This study also showed that the better
players tended to have an increased likelihood of returning to previous level
of play. Players that were drafted in
the first 4 rounds of the NFL draft were 3.7 times more likely to return and
players who started more than 46.2% of the games were 2.8 times more likely to
return to play. Speed position players
(running backs, receivers, linebackers and defensive backs) were 4.0 time LESS likely
to return to play than non-speed position players. Why is this?
First, let’s look at how return to play is
defined in this case. RTP is defined, in
this study, as the first time a player played in a regular season NFL game
after partial lateral meniscectomy. In
the results section of this study, it is reported that although the players
returned to sport, they played 25 fewer games and completed 1.8 fewer seasons
than controls. The fact that speed
players were also 4.0 times less likely to return to sport than non-speed
positions makes you wonder what the impact is on performance.

Stay tuned next week for part II where we
attempt to get more clarity on this issue.
