Fractures of the anterior tibial tuberosity are uncommon, ranging from 0.4% to 2.7% of all epiphyseal lesions reported. Bilateral sequential fractures are even rarer, with less than twenty-eight cases described to date and, as such, there is very little consensus data on their treatment as a whole. We report the first two documented cases of bilateral tibial tuberosity avulsions of the anterior tubercle in Switzerland, treated by open reduction and internal fixation. Both cases were 14-year-old healthy males with no previous medical history, who both suffered extra-articular fractures after falling from a height. The first case was treated in 2012 with a four-year long clinical follow-up and full recovery. The second, treated in 2019, was clinically followed for one year with a complete recovery and has returned to sporting activity at a pre-injury level. Due to the rarity of the condition, a lack of consensus on the optimal therapy, we believe the documentation of these two cases treated by the same team may be of clinical relevance.
