Simultaneous Bilateral Patellar Tendon Rupture in a Patient With Osteogenesis Imperfecta

Simultaneous bilateral patellar tendon rupture is an infrequent and debilitating injury. Although tendon rupture is associated with multiple systemic diseases, there is limited literature regarding its association with osteogenesis imperfecta and successful treatment techniques. We report a case of a 56-year-old man with a history of osteogenesis imperfecta type I who experienced bilateral patellar tendon rupture following a fall from standing height in the absence of other risk factors. Both injuries were effectively treated with primary open repair utilizing Krackow suture technique and transosseous tunnel fixation bilaterally. The patient demonstrated full functional recovery at 14-month follow-up. Osteogenesis imperfecta is a risk factor for the development of bilateral patellar tendon rupture. Open bilateral transosseous suture repair has proven to be successful despite defects in type 1 collagen and underlying tendon weakness.
