Abstract
Background: Several techniques were utilized for internal fixation of patellar fractures which include the AO modified tension band wiring, interfragmentary screws or figure of eight wiring using the cannulated screws. This research aimed to assess the outcomes of fixation of patellar fractures using cannulated screws with tension band wiring. Methods: This prospective clinical study in Orthopedic Surgery department of Zagazig University Hospitals on 18 cases who had fracture patella Patellar fractures fixation utilizing cannulated screws with tension band with follow up period of at least 2 years. Postoperative evaluation was performed according to range of motion, radiological evaluation and Bostman’s score. Results: Progressive improvement of range of motion of knee in both flexion and extension at each follow-up, 94.4% (17 cases) had flexion of > 120° and 100% (18 cases) had extension ≥ 15° by the end of 24 weeks. Radiological union occurred at the 6th postoperative week in 15 patients (83.3%) and after 12 weeks in 17 patients (94.4%). At the follow-up all patients achieved union. Regarding the Bostman’s score, at end of final follow up, it was excellent in 15 patients (83.3%), good in 2 patients (11.1%) and poor in one patient (5.6%). Conclusion: The use of cannulated screws in conjunction with anterior tension band wire to treat transverse patellar fractures is an effective, reliable, and reproducible procedure, Improvements in radiological and functional outcomes, as well as curative effects on patella fracture, complication rates, and the timing of postoperative functional activity, are all benefits of this procedure.
