Key takeaways:
- Patients with PCL injuries resulting from high-energy trauma may have additional knee injuries and complications.
- The most common injury mechanisms were car accidents and falls from height.
According to published results, patients with PCL injuries resulting from high-energy trauma, such as car accidents or falls from height, may have additional knee injuries and be at increased risk for complications.
Izzet Bingol, from the department of orthopedics and traumatology at Ankara Yildirim Beyazit University in Turkey, and colleagues performed a retrospective review of data for 416 patients (mean age, 32.4 years) who underwent PCL reconstruction following high-energy trauma between 2016 and 2022. At a minimum 1-year follow-up, Bingol and colleagues assessed injury mechanisms, associated fractures and soft tissue injuries, as well as postoperative complications.
According to the study, 23.3% of patients had an isolated PCL injury and 76.7% of patients had injuries to multiple ligaments. Bingol and colleagues found 48.1% of injuries were Schenck 2 cruciate ligament injuries. They noted 86.6% of patients had single-stage surgery, while 13.2% of patients required staged surgeries, which were most common after car accidents (P = .014).
Overall, Bingol and colleagues found no significant relationship between trauma mechanisms and incidence of multiple ligament injuries, concurrent injuries or postoperative complications. They found an overall complication rate of 12%, with the highest complications rates found among younger patients and patients who underwent staged surgeries (P = .009).
“This registry-based study revealed that PCL injuries resulting from high-energy trauma frequently coincide with additional knee injuries, leading to a considerable complication risk, particularly knee stiffness, even in the short term,” Bingol and colleagues wrote in the study.
