Arthroscopic suture fixation for avulsion fractures in the tibial attachment of the posterior cruciate ligament.

Abstract

PURPOSE:

The purpose of the study was to highlight our surgical technique of arthroscopic suture fixation for acute tibial eminence posterior cruciate ligament (PCL) avulsion fractures, clinical and radiographic outcomes, and complication rates.

METHODS:

This prospective study enrolled patients who had undergone arthroscopic reduction and suture fixation by use of 4 No. 5 Ethibond sutures (Ethicon, Somerville, NJ) for image-proven displaced PCL attachment fractures of the tibial eminence with posterior knee instability of grade II or higher. The mean follow-up period was 36 months (range, 24 to 45 months). Follow-up assessment included 3 different functional scores, KT-1000 arthrometry (MEDmetric, San Diego, CA), and radiographic evaluation.

RESULTS:

The mean preoperative Lysholm score in the 36 patients was 35 (range, 26 to 55); the mean postoperative Lysholm score was 95 (range, 80 to 100). The mean preinjury and preoperative Tegner scores in the 36 patients were 7.4 ± 1.6 (range, 5 to 9) and 3.2 ± 1.5 (range, 2 to 5), respectively. The mean postoperative Tegner score was 7.0 ± 1.8 (range, 5 to 9). At the final follow-up, the International Knee Documentation Committee scores were observed to be normal (grade A) or nearly normal (grade B) in 33 patients (91.7%) and abnormal (grade C) in 3 patients (8.3%). All 36 fractures achieved union within 3 months. No significant complications such as arthrofibrosis, loss of initial fixation, or wound infection were noted.

CONCLUSIONS:

Treatment of tibial PCL avulsion fractures by arthroscopic suture fixation is a successful technique to restore tibial avulsion injuries of the PCL with well-documented radiographic healing, good clinical outcomes, and low complication rates.

LEVEL OF EVIDENCE:

Level IV, therapeutic case series.
