Patellar Tendon Rupture: Surgical Repair and Protection Using Semitendinosus–Gracilis Graft (DIDT) – Report of Two Cases

Objective: To describe the diagnostic and therapeutic aspects of patellar tendon rupture and to report two cases treated by primary suture protected with a semitendinosus–gracilis (DIDT) autograft frame. Methods: Two patients with traumatic patellar tendon rupture underwent surgery using the same technique: primary repair and protective autologous DIDT frame. A literature review was performed to define the role of this technique. Results: Both patients regained full active extension and satisfactory knee mobility at 6 months, without major complications. Literature data report a success rate above 90% with this method. Conclusion: Patellar tendon repair protected by a DIDT frame is a reliable technique, allowing early mobilization and reducing the risk of rerupture.
