Prevalence and Incidence of ACL Injuries in various sports
it's pretty much the standard to undergo ACL surgery. One study
showed that 31 out of 31 physicians for the teams of the National
Football League would recommend that their players have ACL surgery.
These athletes constitute the most elite football players in the
world, and their physicians are often considered the same for their
profession. In football, the approach to surgery varied slightly
by position: (4)
- Offensive and Defensive Lineman
- 90%-93% recommended acute reconstruction
- 7%-10% recommended a wait-and-see policy
- 84% recommended acute reconstruction
- 10% recommended reconstruction surgery after the season with intense
- 6% recommended a wait and see policy
- non-dominant leg - 84% recommended acute reconstruction
- dominant leg - 61% recommended acute reconstruction
of the physicians, 95% recommended that they wait until the swelling
had subsided to do surgery
of the physicians recommended that they use the patellar tendon
autograft for the surgery.
- 3% recommended the arthroscopic assisted hamstring autograft.
- 3% recommended a patellar tendon allograft for chronic situations
- No allografts were recommended for acute reconstruction surgery.
- 81% allowed return to play in 6 to 9 months after reconstruction.
- 90 - 100% of these athletes returned to play professional football
skiing, there is a very high stress places on the knees. As a result
of this and the ferociousness of skiing accidents, there is a very
high percentage of knee injuries in skiing. From 1930 to 1970, knee
injuries in skiing accounted for 20% of injuries. Over the past
two decades, knee injuries in skiing have risen to around 1 in 3
injuries. Within this group, ACL injuries account for as high as
49% of the knee injuries. MCL injuries occur in a much higher frequency
in skiing, occurring in up to 60% of skiing injuries. (32) Most
ACL injuries in skiing result for hyperextension of the knee or
twisting of the knee while the foot is planted in the boot. The
twisting motion is known as valgus force.
figure represents the motion of a fall that could result in the
tearing of an ACL in skiing. The fall exerts a valgus force on the
knee in combination with external rotation causing the ACL to either
tear or sprain.
most sports, women showed a higher frequency of injury to the ACL.
In women who sustain a knee injury, 80% exhibit an ACL and/or MCL
tear. Men exhibit 46% chance of an ACL and/or MCL tear.
is the most commonly injured area of the body in basketball. For
every 1000 athlete exposures, the knee injury rate is 0.7 in men.
(30) In other words, for men's basketball, there's a 0.07% chance
of injuring a knee. For a knee injury in basketball, on average
one misses 20 exposures, accounting for the most time lost due to

is one of the most popular sport in the work. Worldwide, there is
an estimated 200 million active players. Soccer injuries are mainly
confined to the ankle and the knee which are often caused by overuse.
The frequency of soccer injuries is estimated at 10-35 per 1000
hours of competition, with the majority occurring in the lower extremities.
Knee injuries account for 15-40% of soccer-related injuries. (33)
