Purpose Functional outcomes after Open Reduction Internal Fixation (ORIF) of the patella are variable. Common complica- tions of patella ORIF include persistent anterior knee pain, limited range of motion and symptomatic hardware. The purpose of this study was to evaluate if removal of hardware is beneficial to symptomatic patients after patellar fracture fixation. Methods Patients who presented to our institution between December 2006 and November 2014 with patella fractures treated with ORIF were eligible for inclusion. Patella ORIF was performed using (1) K-wires (KW) with a tension band construct or (2) Cannulated Screws (CS) with a tension band construct. Radiological analyses included (1) AO classification and (2) measurements of prominent hardware length. Patient medical charts were reviewed for demographic and intraoperative data as well as peri/postoperative complications. All patients completed the SF-12 score, visual analog scale, Kujala score, Lysholm score and questionaries’ regarding return to previous activity levels. Results Forty-seven patients met the inclusion criteria. The average time from fracture fixation to removal of hardware was 15.8 (SD ± 14.9) months. The mean follow-up was 43.1 (SD ± 27.1) months. Patella fixation was accomplished using ten- sion band constructs with KW in 28 patients (59.5%) or with CS in
