Purpose and hypothesis: To report clinical and functional outcomes following fixation of tibial avulsion fractures of posterior cruciate ligament (PCL) using spring plate through a modified open posterior approach.
Methods: This is a retrospective study of 10 patients with displaced PCL tibial avulsion fractures treated acutely by open reduction and internal fixation (ORIF) using spring plate. Hughston`s criteria and knee radiographs were used for clinical assessment. Patients were assessed clinically at 2 weeks, and clinically and radiographically at 6 weeks, 3 months.
Results: According to Hughston’s criteria, 9 patients (90%) showed good objective, 8 patients (80%) showed good subjective and 7 patients (70%) showed good functional results. Fair results were seen in 10% (one patient) objective, 20% (2 patients) subjective and 30% (3 patients) functional. There were no poor results.
Conclusions:This study supports that displaced avulsion fractures of the PCL should be treated with open reduction and stable internal fixation and introduce a new, stable and cheap method for fixation.
