ABSTRACT
BACKGROUND:
At present, the optimal treatment for posterior cruciate ligament tibial avulsion fracture (PCLTAF) combined with concomitant ipsilateral lower limb fractures remains unclear. The present study aimed to assess the preliminary outcomes of treatment for PCLTAF with concomitant ipsilateral lower limb fractures by open reduction and internal fixation (ORIF). MATERIALS ANDMETHODS:
The medical records of patients who sustained PCLTAF with concomitant ipsilateral lower limb fractures between March 2015 and February 2019 and underwent treatment at a single institution were retrospectively reviewed. Imaging examinations performed at the time of injury were applied to identify concomitant ipsilateral lower limb fractures. We used 12 matching between patients with PCLTAF combined with concomitant ipsilateral lower limb fractures (combined group; n = 11) and those with isolated PCLTAF (isolated group; n = 22). Outcome data were collected, including the range of motion (ROM) and visual analogue scale (VAS), Tegner, Lysholm, and International Knee Documentation Committee (IKDC) scores. At the final follow-up, the clinical outcomes were compared between the combined and isolated groups and between patients who underwent early-stage surgery and those who underwent delayed treatment for PCLTAF.RESULTS:
Thirty-three patients (26 males, 7 females) were included in this study, with eleven patients having PCLTAF and concomitant ipsilateral lower limb fractures and a follow-up of 3.1 to 7.4 years (average, 4.8 years). Compared to patients in the isolated group, patients in the combined group demonstrated significantly worse Lysholm scores (85.7 ± 5.8 vs. 91.5 ± 3.9, p = 0.040), Tegner scores (4.4 ± 0.9 vs. 5.4 ± 0.8, p = 0.006), and IKDC scores (83.6 ± 9.3 vs. 90.5 ± 3.0, p = 0.008). Inferior outcomes were found in patients with delayed treatment.CONCLUSIONS:
Inferior results were found in patients with concomitant ipsilateral lower limb fractures, while better outcomes were obtained in patients with PCLTAF through early-stage ORIF using the posteromedial approach. The present findings may help determine the prognoses of patients with PCLTAF combined with concomitant ipsilateral lower limb fractures treated through early-stage ORIF.Key words
