SELMI, André Luis et al. Instantaneous center of motion and velocity vector in stifle of dogs undergoing intercondylar notchplasty and articular repair following transection of the cranial cruciate ligament. Cienc. Rural [online]. 2007, vol.37, n.3, pp.777-783. ISSN 0103-8478.

The instantaneous center of motion (ICM) and velocity vector (Vv), after transection of the cranial cruciate ligament (CCL) followed by a fascial strip reconstruction in association with intercondylar notchplasty (IN), were studied in nine adult dogs. The right stifle was submitted to IN followed by fascial strip reconstruction of the CCL (GI) while in the left stifle IN was not performed (GC). Dogs were evaluated the day prior to surgery, immediately after surgery and at 30, 90 and 180 days postoperatively (po), time at which a subgroup of three dogs were euthanatized. The ICM and resulting Vv were determined by radiographic examination of the stifle. All the stifles presented normally positioned ICM and Vv before surgery. No changes were observed in ICM or Vv in all stifles following intra-articular repair, in association or not with IN, throughout the evaluation period, despite the fact that three dogs in GC and two in GI presented a positive cranial drawer sign immediately following surgery, two dogs in GC and GI at 30 days po, and one single dog in each group thereafter until 180 days po. It is concluded that articular repair, in association with IN or not, did not alter stifle biomechanics, in respect to ICM and Vv.
