Arthroskopische Wiederherstellung einer Ausrissfraktur des hinteren Kreuzbands am Tibiaansatz

Avulsion fracture of the tibial insertion of the posterior cruciate ligament (PCL) is a rare condition. Until recently, bony avulsion fractures of the PCL have been repaired with open reduction and internal fixation. Posterior approach commonly used for open repair is rather extensive, yet it does not allow for detection and managment of associated intraarticular injuries of the knee. We report a case of avulsion fracture of the tibial attachment of the PCL managed by arthroscopic reduction and fixation. A large bony fragment that extended into the posterior part of the lateral tibial plateau allowed for reduction and retrograde fixation through anterior portals only.

Fixation of small tibial avulsion fracture of the posterior cruciate ligament using the double bundles pull-through suture method.

BACKGROUND: Avulsion of the tibial insertion of the posterior cruciate ligament is commonly repaired via open reduction and internal fixation with a screw, Kirschner's wire, and suture. In the case of a major bony fragment, this technique is adequate to achieve rigid fixation. In the case of an avulsion fracture with a small bony fragment, however, it is not uncommon to break the bone fragment during screw fixation. We describe a new technique for fixation of an avulsion fracture with a small bony fragment. The technique uses a double bundles pull-through suture technique that repairs the anterolateral and posteromedial components of the posterior cruciate ligament simultaneously. METHODS: From March 1994 through May 1997, 12 patients with small tibial avulsion fractures of the posterior cruciate ligament were treated using this technique. RESULTS: At an average of 18 months after surgery (range, 12-24 months), the preliminary clinical and radiographic results were satisfactory. Eleven patients could return to the same or a higher level of preinjury sports activity. According to the International Knee Documentation Committee rating system, 10 of the 12 patients had normal or nearly normal ratings. CONCLUSION: The double bundles pull-through suture technique can avoid the risk of breakage of the small bony fragment, does not require the removal of hardware, and can achieve adequate repair in the anatomic situation. Our clinical experience suggests that it is a good choice for fixation in cases of avulsion fracture with a small bony fragment.     

Displaced avulsion fractures of the posterior cruciate ligament: Treated by stellate steel plate fixation

Background:

The open reduction with internal fixation is an effective approach for treatment of avulsion fracture of posterior cruciate ligament. The previously used internal fixation materials including hollow screws, absorbable screw, tension bands and sutures have great defects such as insufficient fixation strength, susceptibility to re-fracture, etc. Stellate steel plate is novel material for internal fixation which has unique gear-like structure design. We used stellate steel plate for treatment of displaced avulsion fractures of posterior cruciate ligament in this study.

Materials and Methods:

14 patients (9 men, 5 women; aged, 19–35 years; mean age, 28 years) with displaced avulsion fractures of the tibial insertion of the posterior cruciate ligament were retrospectively analyzed between June 2009 and June 2011. The mean duration from injury to the operation was 8.3 days (range 6–15 days). All the patients were treated with open reduction and internal fixation of a stellate steel plate (DePuy, Raynham, MA 02767, USA). The Lysholm-Tegner knee function score criteria were used to analyze results.

Results:

The mean followup was 24.6 months (range 18–32 months). After 6 months, all the fractures healed and knee joint activity was normal, with no knee stiffness or instability. The Lysholm-Tegner scores were 97.1 ± 1.7 points at the final followup.

Conclusion:

Owing to its unique gear structure, the stellate steel plate design can effectively fix an avulsion fracture block and it is a simple operation with short postoperative rehabilitation time and firm fixation.

Effects of microendoscopy-assisted reduction and screw fixation through a single mini-incision on posterior cruciate ligament tibial avulsion fracture

Introduction  

There are various surgical approaches for the treatment of posterior cruciate ligament (PCL) injury-associated tibial fracture avulsion, including arthroscopy-assisted surgery and open posterior surgery. However, none of these treatments are perfect. We have established a simple procedure with microendoscopy-assisted reduction and cannulated screw fixation for the treatment of this disease through a single mini-incision. In this study, we delineated the effects of this surgical approach for patients with PCL tibial avulsion fracture.
