Bilateral Sleeve Patella Avulsion: A Case Report and Literature Review

Sleeve patella avulsion is rare in children. The bilateral form is exceptional and only few cases are reported in literature. It often goes unnoticed upon initial presentation. MRI is golden standard for a precise description of the lesion. Early diagnosis of patellar sleeve fracture is important for successful treatment.

We present a case of bilateral patellar sleeve fracture in an 11-year-old boy who was diagnosed early and treated surgically with osteosuture in the left knee and a tension band construct in the right one. He regained full and painless active range of motion of bilateral knees within 18 months of his surgery but presented a radiological non-union of the inferior pole of the right patella.
