The aim of treating patella fractures is to restore the integrity of the extensor mechanism. Various treatment methods applied include fastening techniques with different wires, fastening with screws, a combined tension band method and screw technique, segmental patellectomy, a combined tension band method and segmental patellectomy technique, and total patellectomy. Fifty-two patients underwent surgery for isolated closed patella fractures between 2002 and 2012 at the Department of Orthopaedics and Traumatology. Of these 52 patients, 23 patients who completed their follow-up were clinically, radiologically, and retrospectively evaluated. Of the 23 patients, 13 (57%) were male and 10 (43%) were female. The functional status was regarded as excellent in 16 (70%) patients, good in six (26%), and unsatisfactory in one (4%) post-surgery. Radiological evaluation of the patients showed that there was type 1 PFA in five (22%) patients, type 2 PFA in five (22%), type 3 PFA in eight (35%), and type 4 PFA in five (22%). The degree of union was radiologically evaluated in all patients during the follow-ups. Implant irritation, implant migration, and fractures were the most frequently observed complications.
