A young patient with a posterolateral knee dislocation underwent open reduction and medial collateral ligament repair. Successful outcomes were observed at six months, avoiding immediate multi-ligament reconstruction.

Area of Science:

Orthopedic Surgery
Sports Medicine
Traumatology

Background:

Posterolateral knee dislocation is a severe injury often involving multiple ligamentous structures.
Management strategies range from conservative approaches to surgical repair, depending on injury severity and patient factors.

Observation:

An 8-year-old male sustained a posterolateral knee dislocation following a fall.
Initial closed reduction was unsuccessful, necessitating open reduction and internal fixation.
Associated injuries included disruption of the anterior cruciate ligament, posterior cruciate ligament, and medial collateral ligament.

Findings:

The patient underwent open reduction and repair of the medial collateral ligament.
At the 6-month follow-up, the patient reported no subjective pain or instability.

This approach prioritized addressing the most acutely unstable component while deferring potential anterior and posterior cruciate ligament reconstruction.

Implications:

Early repair of the medial collateral ligament in pediatric posterolateral knee dislocations can lead to favorable short-term outcomes.
A staged surgical approach may be beneficial in young, active patients, allowing for assessment of long-term stability and function.
This case highlights the importance of individualized treatment planning for complex knee injuries in pediatric populations.
