Posterior talofibular ligament (PTFL) injuries are far less common than other lateral collateral ligament injuries of the ankle and almost always occur with other injuries 1.
The estimated incidence is ~10% (range 4-20%) on MRI in patients with ankle injuries 1,4,6.
One potential reason for relatively lower PTFL injury rates is its maximal load to failure is 3x that of the anterior talofibular ligament (ATFL) 2 and it is not a major stabilizer of the lateral ankle joint 3.
Associations
PTFL injuries have been associated with 1,5:
MRI is more sensitive and specific than ultrasound for the detection of PTFL injuries 6.
