Core Tip

Core Tip: Simultaneous injury to the anterior tibial tuberosity and the patellar tendon is rare, and the etiology is unclear. To date, no definitive treatment protocols for this pathology have been reported. In this case report, we present a review of the studies published to date. The diagnoses must be based on high clinical suspicion, physical examinations, and imaging methods. Open reduction and internal fixation of the bone fragment are almost always necessary. Patellar tendon repair is performed using sutures, anchors, staples, or screws.
