Prevention of cruciate ligament tears.
Anterior cruciate ligament rupture requires surgery. It is a major reconstruction involving extensive rehabilitation over 5 months.
This injury sometimes will end a player’s career so can we do anything to prevent them? YES!!!!!
As 60 to 80% of ACL injuries happen in a non contact situation it is worth working on prevention.
In soccer two common mechanisms cause tears
1. Cutting manoeuvre i.e. side stepping with rotation stress. Typically with the knee turned out and slightly bent and the player takes off with the foot fixed and the knee turns in with the aim of changing direction.
2. Landing on one leg close to full extension stresses the ACL
Clinical Features of ACL tear
A patient often describes an audible pop or something going out and then going back.
Most are extremely painful.
Knee is usually very swollen very quickly.
Why does the ACL tear in situations that the player has performed many times in the past?
There is usually an external factor that makes the player more susceptible.e.g. Being pushed, having an unusually wide foot position, trying to avoid a collision, fatigue and loss of concentration.
Ladies are between 2 and 8 times more at risk due to hormones, anatomical differences, shoe surface interface and neuromuscular differences.
