All-soft tissue quadriceps tendon autograft and bone-patellar tendon-bone autograft demonstrate no significant ACL tunnel widening: An MRI comparison.
Purpose: This study sought to quantify the tunnel widening associated with quadriceps tendon (QT) autograft after anterior cruciate ligament reconstruction (ACLR) and compare it to bone-patellar tendon-bone (BTB) autografts.
Methods: A retrospective review of each ACLR performed at a single academic institution from 2011 to 2021 were reviewed. Subjects with repeat ipsilateral knee magnetic resonance imaging (MRI) studies performed after ACLR were included. Two reviewers independently measured the maximum diameter of the femoral and tibial tunnels 1 cm from the aperture. Tunnel widening was calculated as the difference between the initial drilled diameter and the measured diameters.
Results: Seventy-five patients (38 BTB and 37 QT autografts) were identified including 42 females and 33 males. With respect to graft type (QT vs. BTB), there was no statistically significant difference in median patient age (19.0 (16.0-31.5) years vs. 20.0 (16.8-30.0) years respectively; p = n.s.) or median time to MRI (12.0 [9.0-19.5] months vs. 13.0 [7.0-43.3] months respectively, p = n.s.). Mean tunnel diameter changes or widening was statistically significantly greater for QT autografts than BTB autografts at the tibial tunnel: (0.4 [±0.6] mm] vs. -0.4 [±1.1 mm; p < 0.001). Similarly, the mean tunnel diameter change was also significantly greater at the femoral tunnel for QT compared to BTB. (0.2 [±0.6] mm vs. -0.4 [±0.8] mm; p < 0.001) However, no patients with QT grafts demonstrated tibial or femoral tunnel diameters >12 mm.
Conclusion: Although QT autografts had a statistically significant greater amount of tunnel widening compared to BTB autografts; the mean tibial and femoral net widening of 0.4 mm and 0.2 mm, respectively, does not meet previously reported clinically significant values. Thus, the tunnel widening presented in this study is unlikely to affect clinical outcomes and should not preclude the use of either graft.
Level of evidence: Level III (Retrospective comparative study).
