Differentiation of prepatellar bursitis from post-traumatic degloving injuries (Morel-Lavallee lesions) about the knee can occasionally present a diagnostic dilemma for clinicians and radiologists, although several features have been described as suggestive of a MLL etiology.

Our study adds to the evidence suggesting that intralesional fat globules and fluid extension beyond the confines of the normal prepatellar bursa are common findings in MLL lesions about the knee and suggestive that a lesion is unlikely to be an isolated prepatellar bursitis.
