[Revision surgery of anterior cruciate ligament plasty].

Introduction: anterior cruciate ligament injuries (ACL) continue increasing in frecuency in the general population and sportmen who practice soccer and american football where we can locate 53% of the total of cases, the annual incidence is 70 per 100,000 persons. The incidence of this injuries has being increasing in women probably of the increase of the participation in such sports.

Objective: to document the causes of anterior cruciate ligament (ACL) plasty failure, as well as the diagnosis, surgical technique, and postoperative care of a revision ACL plasty surgery.

Material and methods: a search for relevant information, original research articles, clinical trials, and reviews in indexed journals was performed.

Results: anterior cruciate ligament injuries continue to increase among the general population and athletes who play soccer and American soccer mainly, in this population group we found 53% of the total cases. The gold standard for treatment is arthroscopic reconstruction of the ligament. ACL reconstruction surgery has good results, with an estimated 75-90% success rate. Long-term failures of anterior cruciate ligament repair represent 5-25%. Among the factors associated with this failure are technical errors, traumatic antecedents, biological factors, among others.

Conclusions: in ACL revision surgery good results can be achieved with respect to graft stability, return to play and functional stability of the knee, but the results are generally inferior to those of primary ACL reconstruction.
