Introduction and purpose: The treatment of PCL injuries has undergone many changes in recent decades and the number of stabilisations has increased. The improvement of arthroscopic techniques makes it possible to stabilise the PCL safely and gives good results.

The purpose of this paper is to present a retrospective study of arthroscopic PCL stabilisations carried out in our hospital from 1997 to 2003.

Materials and methods: Between 1998 and 2003 we performed 25 PCL reconstructions, associated with posterolateral angle stabilisations in four cases. The mean age was 21.4. The mean follow-up was 36.5 (18–74). We used autologous BTB graft in 18 cases and Achilles tendon allograft in 7. In all cases a single-bundle arthroscopic reconstruction was performed. Gravitational X-rays were taken of all patients before and after surgery to assess the posterior drawer. We used IKDC for postoperative evaluation.

Results: The mean posterior drawer in preoperative neutral rotation was 7.51 mm (6.5–15), and 2.37 mm postoperative. Postoperative IKDC evaluation was as follows: 6 cases (24%) A, 16 (64%) B, 3 cases (12%) C. In 88% of the cases the athletes returned to normal sports activity.

Among the complications was one case of infection of the surgical wound in a reconstruction of the posterolateral angle.

Conclusions: Our retrospective study suggests that the single-bundle reconstruction procedure we used gives good functional results, and most of the patients returned to their previous sports activity.
