Bilateral Spontaneous Concurrent Rupture of the Patellar Tendon in the Absence of Associated Local or Systemic Disease

Patellar tendon rupture in children is very rare. When it occurs, patellar tendon is usually ruptured either from the upper end as a sleeve fracture of the patella or from lower end as an avulsion fracture of the tibial tuberosity. In this report, we present the case of an otherwise healthy 9-years-old boy who had subsequent bilateral patellar tendon ruptures through the midparts, which has not been published previously in the literature. Treatment was performed with primary end-to-end repair, reinforcement with cerclage wires and fresh-frozen achilles tendon augmentation for both sides.

“…Classically, a primary repair of the tendon with suture has been augmented with wire cerclage to relieve tension across the repair site while the tendon is healing. 8,10,19,20 This repair has had reliable results but often requires a secondary surgery for wire removal, either for mechanical irritation or wire breakage. 8,[19][20][21] The purpose of this study was to evaluate the biomechanical properties of new suture material for both the repair and augmentation.…”

We evaluated the biomechanical properties of FiberWire (Arthrex, Inc, Naples, Florida), a new suture material, for both repair and augmentation as compared to standard Ethibond suture (Ethicon, Inc, Somerville, New Jersey), hypothesizing that primary repair and cerclage augmentation with the new suture material would have similar biomechanical properties as a standard repair with wire augmentation. Forty-five fresh bovine knees were placed in 3 groups of equal size: (1) #5 Ethibond tendon repair plus 18-gauge wire augmentation; (2) #5 FiberWire repair plus #5 FiberWire augmentation; and (3) #5 Ethibond repair plus #5 FiberWire augmentation. A straight static pullout test was performed, randomly alternating between the different groups. Gap formation was measured at the center of the repair by a metric ruler, with the examiner blinded to the developing force-tension readout. For each millimeter of gap formation (1-10 mm), the force on the repair was recorded, as well as the force at the ultimate failure of the repair, designated by breakage of any repair material. Analysis showed no significant difference between the standard Ethibond/wire repair and the FiberWire/FiberWire repair. The Ethibond/FiberWire repair was shown to be significantly weaker than the other 2 groups. Ultimate failure data indicated that the Ethibond/wire repair was significantly stronger than both other groups. No significant differences were found between the FiberWire/FiberWire repair and the Ethibond/FiberWire repair. Newer, stronger suture material for both primary repair and augmentation may provide equivalent biomechanical strength at clinically significant levels.
