# Acute compartment syndrome in an anterior cruciate ligament revision: a case report

## TL;DR

A soccer player developed acute compartment syndrome during ACL revision surgery, but timely treatment allowed full recovery.

## Contribution

This case report highlights intraoperative diagnosis and treatment of acute compartment syndrome during ACL revision.

## Key findings

- ACS was diagnosed and treated intraoperatively, preventing postoperative complications.
- The patient returned to sports within nine months with no residual deficits.
- Early intervention can lead to excellent functional outcomes in ACS cases.

## Abstract

Acute compartment syndrome (ACS) is a rare but serious complication of anterior cruciate ligament (ACL) reconstruction. We present the case of a 21-year-old male soccer player who developed ACS during revision ACL reconstruction. The patient had previously undergone ACL reconstruction and revision was indicated for recurrent instability and graft rupture confirmed by MRI. At the end of the procedure, marked intraoperative edema prompted a medial fasciotomy, which decompressed the superficial and deep posterior compartments. The patient recovered without complications, returned to sport within nine months, and experienced no residual deficits. This case is distinct in that ACS was diagnosed intraoperatively, enabling immediate fasciotomy and preventing postoperative morbidity. Comparison with existing literature highlights that while ACS after ACL reconstruction is uncommon, it remains a critical risk. Lessons include the need for intraoperative vigilance, timely surgical decompression when swelling suggests impending ACS, and the potential for excellent functional outcomes with early intervention.
