Management of Chronic Quadriceps Tendon Rupture: A Critical Analysis Review.

» Chronic quadriceps tendon (QT) ruptures are uncommon injuries that present treatment challenges due to their complex nature and the limited evidence to guide management. » Timely diagnosis and surgical management of acute QT injury are imperative to optimize patient outcomes as delayed diagnosis leads to poorer results regardless of treatment modality. » Elements of chronic QT ruptures that may complicate surgical management include patient age, comorbidity, scar-tissue formation, amount of quadriceps muscle/ tendon retraction, and distalmigration of the patella with contraction of the tendon. » Treatment options for chronic QT ruptures include primary repair with or without vastus advancement, V-Y tendon lengthening with or without tissue augmentation, and autograft or allograft reconstruction.
