Ground reaction forces were measured from the hind limbs of 9 dogs before and after stabilization of unilateral cranial cruciate ligament rupture. Before surgery, peak vertical force, associated impulses, and weight distribution were significantly less (multivariate analysis P less than 0.02) in the affected limb, compared with the clinically normal limb. Craniocaudal peak forces and impulses, divided into braking and propulsion, also were significantly less in the affected limb. At a minimum of 7 months after retinacular imbrication, all vertical and craniocaudal measurements in the affected limb were increased significantly. Significant changes were not found in the normal limb. Furthermore, at the postoperative evaluation, there was no significant difference in any measurement between the affected and normal hind limbs. The results indicated restoration of function in the cruciate-deficient limb when compared with the clinically normal hind limb at a walking gait during the study time period.
在单侧颅侧十字韧带断裂稳定前后，对9只犬的后肢进行了地面反作用力测量。术前，与临床正常肢体相比，患侧肢体的垂直峰值力、相关冲量和重量分布显著降低（多变量分析P<0.02）。患侧肢体的头尾向峰值力和冲量，分为制动和推进力，也显著降低。在支持带重叠至少7个月后，患侧肢体的所有垂直和头尾向测量值均显著增加。正常肢体未发现显著变化。此外，在术后评估中，患侧和正常后肢之间的任何测量值均无显著差异。结果表明，在研究时间段内的步行步态中，与临床正常后肢相比，十字韧带缺损肢体的功能得以恢复。
