Evaluation of the Results of Acute Posterior Cruciate Ligament Avulsion Fixation in Patients Presenting to Besat Hospital in Hamadan, Iran

The knee is one of the largest joints in the body that, given its specific position, is directly exposed to blunt and posterior cruciate ligament avulsion. Considering the importance of this lesion, this study was conducted with the aim of investigating the results of posterior cruciate ligament (PCL) avulsion fixation in patients presenting to Besat Hospital of Hamadan, Iran, during 2013-2015.
In this descriptive cross-sectional study, 15 patients with acute knee injery symptoms treated with PCL fixation were studied. All the patients were operated by one surgeon. The following factors were considered in data analysis: demographic data, side of the injured knee, knee pain, lameness, swelling, posterior instability, locking, osteoarthritis changes, and mean Lysholm score.
This study was conducted on 13 (87%) male and 2 (13%) female patients with the mean ages of 27.2±4.3 and 24.5±0.5 years, respectively (P=0.526). Overall, 47% of the lesions were in the right knee and 53% in the left knee. After one year, we observed knee pain in 3 (20%), lameness in 5 (33%), swelling in 3 (20%), and posterior instability in 10 (67%) patients. Locking was not detected in any of the cases. Five patients (33%) were using a cane for a long time. The mean Lysholm score was 87.5. Outcome was good in six patients, satisfactory in four, and moderate in five patients.
One year after traumatic posterior cruciate ligament avulsion fixation, knee function was moderate to excellent.
