Partial rupture of anterior cruciate ligament: preliminary experience of selective reconstruction.

<bold>Background: </bold>Partial lesions of the anterior cruciate ligament (ACL) are more common than is generally thought, accounting for about 10-12% of ACL injuries. Selective reconstruction may be considered as an option in isolated bundle rupture. The purpose of this study is to evaluate both subjective and objective clinical results, as well as functional recovery time, after selective arthroscopic single-bundle reconstruction in a consecutive series of patients affected by partial ACL rupture.<bold>Materials and Methods: </bold>Thirty-six patients undergoing selective reconstruction of a single ACL bundle were retrospectively evaluated from a series of 354 ACL reconstructions performed over a 3-year period. Although the suspicion of partial lesions was present at clinical and magnetic resonance imaging (MRI) evaluation, final diagnosis was obtained during arthroscopy. All patients were operated using the same technique and type of fixation, and undergoing the same functional recovery protocol.<bold>Results: </bold>Mean follow-up was 64 months (48-84 months). All patients but one achieved good functional recovery and returned to their sports within a mean period of 6.1 months. A single patient complained of postoperative instability 1 year after the index operation and needed further surgery. No complications were recorded.<bold>Conclusions: </bold>Selective reconstruction of partial ACL injury is a method to bear in mind because it offers quick functional recovery. Specific technical and diagnostic steps should be performed and discussed with patients preoperatively.<bold>Level Of Evidence: </bold>Level 4, retrospective study. [ABSTRACT FROM AUTHOR]
