Étude laxométrique après reconstruction du ligament croisé antérieur du genou

We made a follow-up at three, six and 12 months after 148 ACL reconstructions; 53% of the patients had an intensive rehabilitation of four weeks in the center during two months after surgery (including isokinetic and nonisokinetic reinforcement). On KT 2000 arthrometer, laxity and compliance are greater on the operated side. Laxity increases from three to six months but remains stable from six to 12 months after the plasty. After meniscal repair, laxity tends to be greater. Intensive rehabilitation in the center does not increase the laxity but when the resumption of the pivot athletic activities is too precocious, laxity is most frequently pathological. When isokinetic ratios are pathological, shears tend to be more frequently greater but multivariate analysis does not find correlation between functional (ARPEGE), isokinetic or laxometric data.
