Introduction
A displaced tibial-side bony avulsion of the posterior cruciate ligament (PCL) should be anatomically reduced and fixed. Many techniques have been described for fixation of these injuries. All have been proven to be effective in the treatment of PCL avulsion fractures. The aim of this study was to assess the results and clinical outcomes of displaced tibial-side PCL avulsion fractures treated with arthroscopic retrograde screw fixation.
Settings and design
A case series study was held at Alexandria University.
Patients and methods
From 2010 to 2013, 24 patients had displaced avulsed PCL tibial-sided injury. They were all males. In all of them, the fragment was large (at least 1.5 cm). They were fixed arthroscopically using a single retrograde cannulated screw. The median age was 25.5±2.67 years. All patients were followed up clinically and radiologically for a median of 27±1.5 months.
Statistical analysis
SPSS, version 20.0, Chicago, Illinois, was used for statistical analysis.
Results
Postoperatively, the mean Lysholm score was 96±1.3 and the Tegner score was 7.7±0.4 points. The range of motion improved significantly from 97.14±5.4 to 130.7±2.67, with a value less than 0.01. All patients achieved radiological union at a mean of 3.2±1.08 months.
Conclusion
Arthroscopic-assisted retrograde screw fixation is an effective, safe, and easy technique for fixation of these types of injury.
