The authors undertook this study in order to present the results of anterior cruciate ligament (ACL) augmentation for patients having rotational instability despite an intact vertical graft instead of conventional revision ACL reconstruction. ACL augmentation surgery with a horizontal graft was performed to augment a healed vertical graft on five patients and an accelerated rehabilitation protocol was instituted. Functional outcomes were assessed by the Lower Extremity Functional Scale (LEFS) and the Modified Cincinnati Rating System (MCRS). All the patients studied completed physical therapy within 5 months and were capable of return to full military duty without limitation. LEFS and MCRS were significantly improved.
This study found that ACL augmentation with a horizontal graft provides an excellent alternative to ACL revision reconstruction for patients with an intact vertical graft, allowing a speedier return to duty for military service members.
