Introduction:
Anterior cruciate ligament (ACL) reconstruction is a "daily" surgery. Nevertheless, pretibial cyst formation is a very rare complication and may appear years after the reconstruction. Even more infrequent is the recurrence of this complication.
Case Report:
We present a patient who developed a pretibial cyst 44 months after an ACL reconstruction and who underwent three open surgeries due to recurrence. Up to date, there are no symptoms or signals of cyst recurrence after 18 months of follow-up.
Conclusion:
Initial surgical resection might have failed due to insufficient surgical treatment. In case of suspicion of articular communication, we consider that the correct treatment is the resection of the cyst, proper curettage of the tunnel walls and a thorough filling of the space with bone graft. This course oftreatment may avoid a recurrence.
