A ligament that stabilizes the knee.
The PCL limits the backward movement of the tibia. It can be injured during an impact on a flexed knee, a fall, or a sports injury. Pain, swelling, and a feeling of instability may prompt a consultation.
Defining the injury
The examination looks for posterior laxity and involvement of other ligaments. Radiographs and MRI complete the assessment depending on the context; stress radiographs can help quantify laxity.
Treatment without surgery is possible
Some isolated injuries require a custom orthosis and specific rehabilitation, particularly of the quadriceps. The protocol protects the ligament during recovery. Weight-bearing instructions and exercises are personalized.
When to consider reconstruction?
Persistent instability despite treatment or damage to multiple ligaments may lead to consideration of reconstruction. The choice depends on the assessment and functional needs.
Long-term follow-up
Resumption of activities depends on recovery and any associated injuries. The PCL protocol is specific: do not apply the protocol for any other knee injury.
Your questions.
Is the treatment the same as for an ACL tear?+
No. The orthosis, exercises, and their progression are adapted to the injured ligament.
