Anterior cruciate ligament avulsion fracture following medial unicompartmental knee arthroplasty: A case report.

ABSTRACT:

Introduction

Anterior cruciate ligament (ACL) avulsion fracture after unicompartmental knee arthroplasty (UKA) has not been reported until recently. We describe a case of ACL avulsion fracture that developed after medial UKA.

Case presentation

A 57-year-old woman underwent UKA for right medial compartment osteoarthritis. She developed knee pain and swelling at 2 weeks after UKA, and radiographs showed an ACL avulsion fracture at 3 weeks after UKA. After conservative treatment failed, the fracture was fixed using screws. After 5 months from internal fixation, bone union was confirmed, and the screws were removed. At 16 months after removing screws, there was no further complication.

Discussion

The patient did not exhibit a fracture on the radiograph taken immediately a
