The application of the Nice knots as an auxiliary reduction technique in displaced comminuted patellar fractures

•To our knowledge, this study is the first to describe application of the Nice knot as an auxiliary reduction aid in the treatment of comminuted patellar fractures.•The Nice knot is a sliding, double-stranded, self-stabilizing knot that allows for tightening to be stopped and resumed at any stage to facilitate optimal final knot position and anatomic reduction.•Compared to traditional reduction techniques, use of the Nice knot as an auxiliary reduction aid was associated with reduced surgical time, decreased intraoperative blood loss, and satisfactory postoperative outcomes.
