How does a PCL injury happen?
The posterior cruciate ligament can be injured by a direct force to the front of the tibia, hyperflexion, sports trauma or high-energy injury.
Assessment
Examination focuses on posterior laxity, alignment, associated ligament injury and functional instability. MRI can help define the ligament injury and associated damage.
Non-operative treatment
Selected isolated PCL injuries can respond well to structured rehabilitation, quadriceps strengthening and bracing when indicated.
When is reconstruction considered?
Surgery may be considered for persistent symptomatic instability, severe isolated injuries in selected patients, combined ligament injuries or when functional demands justify reconstruction.
Frequently asked questions
Can a PCL tear heal without surgery?
Many isolated PCL injuries can be managed non-operatively, particularly when instability is limited and rehabilitation restores good function.
Is a PCL injury the same as an ACL injury?
No. The PCL and ACL control different directions of tibial movement and have different injury patterns and treatment considerations.
