Purpose / Aim of Study: To overcome the problem of prominent metallic im- plants, we present a technique based purely on braided sutures – the novel “KnotMe technique”. Materials and Methods: The suture is passed through soft tissue solely, that is: the quadriceps tendon, the patellar ligament, and the medial and lateral reti- nacula. Upon reposition the first and second sutures are passed through soft tis- sue in two distinct ways: “the modified circular suture” and “the modified figure- of-eight” suture, respectively. Both sutures start in the upper lateral corner of the quadriceps tendon where knots are likewise tied. If comminution is present the fracture is converted into a simple two-part fracture with one or two “box sutures” around the upper and lower pole, respectively. Findings / Results: This technique is here described on our first six patients treated with this technique at our institution along with their clinical and radio- logical follow up. It is furthermore described in a step-wise, standardized way that can be adapted to all types of patella fractures. The described suture con- figuration allows maintenance of inter-fragmentary reduction until bony union without symptoms from the suture material. Conclusions: We believe that the “KnotMe” technique is a safe and promising alternative to traditional metallic fixation methods. 214.
