    Area of Science:

    • Orthopedics
    • Sports Medicine
    • Anatomy

    Background:

    • The fabella is a sesamoid bone within the popliteus tendon.
    • Fabella Syndrome involves localized pain and tenderness around the fabella.
    • Pain exacerbates with full knee extension.

    Purpose of the Study:

    • To describe the clinical presentation of Fabella Syndrome.
    • To evaluate diagnostic methods for Fabella Syndrome.
    • To assess the efficacy of surgical intervention for Fabella Syndrome.

    Main Methods:

    • Diagnostic evaluation including local anesthesia tests.
    • Review of conservative treatment outcomes.
    • Surgical extirpation of the fabella.

    Main Results:

    Related Experiment Videos

    • Sharp pain and tenderness localized to the fabella area are key indicators.
    • Conservative treatments were found to be ineffective.
    • Surgical extirpation led to sustained symptom resolution.

    Conclusions:

    • Fabella Syndrome is a distinct clinical entity causing knee pain.
    • Diagnostic local anesthesia can aid in identifying the fabella as the pain source.
    • Surgical extirpation offers a definitive treatment option for refractory Fabella Syndrome.
