Abstract

PURPOSE
To introduce the results of surgical methods in tibial avulsion fracture of the posterior cruciate ligament (PCL) and arthroscopic exam as useful therapeutic one.
MATERIALS AND METHODS
32 cases with tibial avulsion fracture of the PCL were received surgical treatment and followed up at least 12 months. Clinical results were evaluated with IKDC score and posterior laxity test with Telos device. The posterior approach was performed in 31 cases (19 screw fixation, 12 pullout suture) and arthrosco-pic reduction and fixation in one. Since 1995, arthroscopic exam was performed on the beginning of operation in all cases and combined injury was treated simultaneously.
RESULTS
The IKDC scores were A (normal) in 8, B (nearly normal) in 21, C (abnormal) in 2, D (severe abnormal) in 1 and two of C and D showed posterior instability. 7 of 17cases from 1995 had a combined injury and all revealed above B. The result of compar-ison of screw fixation and pullout suture technique showed no difference between them.
CONCLUSION
The results were favorable regardless of surgical methods and arthroscopy was useful in diagnosis and treatment of combined injury.
