Background: Spontaneous bilateral patellar tendon rupture is a rare condition, which is known to occur in patients with systemic illness like SLE, rheumatoid arthritis and renal failure that warrant long term systemic steroid use. It is even more exceptional in patients without such predisposing conditions. So far, only 8 other cases with neither an underlying systemic disease nor significant trauma have been reported.
Methods: We report a case of spontaneous sequential bilateral patellar tendon rupture following separate episodes of trivial trauma in an active 45 year-old male without any systemic disease known to cause patellar tendon weakening.
Results: Treating the tendon ruptures with direct surgical repair using non-absorbable synthetic sutures and reinforcement with stainless steel cerclage wires yielded satisfactory results with the patient achieving full, painless range of movements without any extensor lag in four months. This result was maintained at six years follow-up.
Conclusion: Our case is particularly remarkable for two episodes of very trivial sequential injuries leading to bilateral spontaneous patellar tendon rupture in an active individual.
