Abstract

Bilateral patella tendon rupture is rare, particulary when associated with osteogenesis imperfecta. Brittleness of the bone in osteogenenesis imperfect patients may cause this rupture. We report on this rare case and suggest the direct repair with the additional wire loop as a proper treatment option for patients with the substantial rupture of patella tendon.

Figure

• 

  Figure 1 Plain radiographs showed patella alta and fracture of the patellar inferior pole on both sides.

• 

  Figure 2 Computed tomography scan was taken on both knees and magnetic resonance imaging was also performed on the right knee. (A) The identical avulsion fracture of patellar at the inferior pole on both knees. (B) Patellar tendon rupture on the right knee.

• 

  Figure 3 Postoperative radiographs. The repair was done on both sides using Ethibond suture for patellar tendon rupture with an additional wire loop to fixate the fragile patellar.

• 

  Figure 4 At 10 months follow-up, the patient was able to flex the knees up to 100 degrees and was able to perform straight leg raise on both knees.

• 

  Figure 5 The patient had been admitted to the hospital 13 times in the past for multiple fractures.
