Keywords:Hypermobile Lateral Meniscus, Knee, Locking, Popliteomeniscal Fascicle
Objective. The hypermobile lateral meniscus of the knee is a rarely described entity. In this case report we aim to draw attention to the clinical presentation and MR imaging findings of this pathology.
Case Report. We review the clinical and imaging findings that led to the diagnosis of hypermobile lateral meniscus with transient subluxation causing intermittent locking, and which subsequently led to successful surgical treatment.
Conclusion. Hypermobile lateral meniscus is rarely diagnosed prospectively on MR imaging. A better understanding of this uncommon condition will lead to prompt diagnosis and effective treatment, with a better outcome for the patient.
