Hamstring Anterior Cruciate Ligament Autograft Contributes to a Delayed Symptomatic Cyclops Lesion: A Case Report

TL;DR

A case report shows a rare delayed cyclops lesion after hamstring ACL surgery, highlighting the need for awareness and a successful treatment approach.

Contribution

This case report demonstrates a delayed cyclops lesion following hamstring ACLR, which is not commonly documented in the literature.

Findings

A 21-year-old male presented with a symptomatic cyclops lesion three years after hamstring ACLR.

Surgical debridement and notchplasty successfully managed the lesion with meniscal horn repairs.

The case highlights the possibility of delayed cyclops lesions and their clinical presentation.

Abstract

Cyclops lesions are characterized as fibroid nodules with granulation tissue that looks similar to a cyclops eye during arthroscopy. These are rare postoperative complications following anterior cruciate ligament reconstruction (ACLR), presenting typically within six months of their reconstruction. This case report presents a 21-year-old male, three years following hamstring autograft ACLR, with a symptomatic cyclops lesion. Contrary to the reported literature, this delayed presentation showed a painful flexion contracture of the knee and intraoperative findings consistent with a cyclops lesion. The treatment consisted of surgical debridement and notchplasty with subsequent posterior medial and lateral meniscal horn repairs. This case report presents a lesson to indicate that cyclops lesions can occur in a delayed setting following ACLR and to show a technique for successful surgical management of the lesion.
