Case:
A 29-year-old man presented 2 years after anterior cruciate ligament (ACL) reconstruction by autologous semitendinosus graft and suspensory fixation on both tibial and femoral sides for chronic drainage of clear fluid from an anteromedial wound at the site of the tibial tunnel with a visible sinus tract. Magnetic resonance imaging showed a transtibial articulocutaneous fistula. The patient was treated by tunnel debridement, impaction bone grafting, bioresorbable interference screw, and cement to fully seal the tunnel. The surgery was successful with good clinical outcomes for recurrence and knee stability.
Conclusion:
Communicating transtibial articulocutaneous fistulas are rare complications after ACL reconstruction. Tunnel debridement and filling with graft material affected by an interference screw seem to be an effective method for dealing with such a clinical scenario.
