Aim
The development and the experimental application of an innovative surgical ACL reconstruction technique based on the results of an anthropometric study for the tibial insertion of the ACL.
Methods
The rationale of the reported technique was based on the reproduction of the insertion characteristics of the natural ACL, by using a pair of grafts with common origin and different insertions (Δ-plasty). Experimental surgery was conducted on porcine knee joints mounted on an bench device and using grafts from porcine feet. Grafts were selected according to biomechanical performance in tension and their routing was precisely achieved by means of a specially designed targeting device guiding the drills. Anterior and posterior graft bundles were tensioned and stabilized at flexion angles of 30 and 100 Grade respectively. The stability of the reconstructed joints at various flexion angles was evaluated by subjective judgment using a drawer test and their performance was compared to conventionally reconstructed witnesses.
Results
Compared to conventional ones, the reported technique was of equivalent surgical demands and provided an encouraging outcome with respect to knee stability.
Conclusions
The innovative Δ-plasty technique for the reconstruction of ACL is a promising surgical approach, deserving further evaluation with in vitro biomechanical testing.
