Arthroscopic Treatment of Concurrent Avulsion Fracture of Anterior and Posterior Cruciate Ligament with Suspension Device

Posterior cruciate ligament rupture and all-epiphyseal repair with suture tape augmentation in a 5-year-old girl: a case report and review of the literature

INTRODUCTION

Only a few case reports regarding pediatric posterior cruciate ligament (PCL) ruptures without bone avulsion exist in the literature. The present study aims to share our experience in the diagnosis, treatment, and prognosis of a child with a proximal PCL tear.

MATERIALS AND METHODS

This article reports a 5-year-old female diagnosed with a proximal PCL tear. The ruptured PCL was repaired with an all-epiphyseal suture tape augmentation (STA) without evidence of growth plate violation.

RESULTS

The suture tape was removed under arthroscopy and revealed the PCL was re-attached at 12 months after the first surgery. And at the time of this report, 36 months after surgery, she was doing well without any problems and with negative posterior drawer test.

CONCLUSIONS

Pediatric PCL tear without bone avulsion is rare. However, the torn PCL was noticed healed based on an arthroscopic second-look.

Surgical treatment for a combined anterior cruciate ligament and posterior cruciate ligament avulsion fracture: A case report

BACKGROUND

Independent avulsion fractures with anterior cruciate ligament (ACL) or posterior cruciate ligament (PCL) attachment are relatively common among tibial intercondylar eminence fractures, and their postoperative outcomes are generally favorable. Conversely, huge avulsion fractures of the intercondylar eminence containing the attachment site of both the ACL and the PCL are extremely rare, and the reported clinical outcomes are poor.

CASE SUMMARY

We describe a 30-year-old Japanese male's huge avulsion fracture of the intercondylar eminence of a tibia containing the attachment site of both the ACL and PCL, together with a complete tear of the medial collateral ligament and a partial tear of both the medial and lateral menisci caused by a fall from a high place. All of these injuries were treated surgically, with anatomical reduction and stable fixation. The limb function at 1 year post-surgery was excellent (Lysholm score: 100 points).

CONCLUSION

Although this patient's complete surgical repair was complex, it should be performed in similar cases for an excellent final clinical outcome.
