We measured the configuration of the femoral condyles on lateral radiographs in 100 consecutive, prospectively-studied patients with a complete rupture of the anterior cruciate ligament, with or without associated lesions of the menisci and collateral ligaments. The patients had mainly low-to-moderate activity demands, and in all the patients the cruciate tear was primarily treated non-operatively. A quotient was calculated from the measurements of sagittal depth and axial height in order to describe the geometry of the femoral condyles. Measurements were reproducible with an intra- and interobserver coefficient of correlation of 0.89-0.98. At follow-up, after 5 (3-6) years, 16 patients had developed disability leading to reconstructive surgery. The remaining 84 patients did not have any major functional limitations, but some had reduced their activity level. Individual variations in the articular geometry were found with a more spherical shape of the femoral condyles in the patients where non-operative treatment had failed. Our findings indicate that articular geometry is of importance for function after an anterior ligament lesion.
我们对连续100例前瞻性研究的前交叉韧带完全断裂患者的膝关节外侧X线片上的股骨髁形态进行了测量，这些患者伴有或不伴有半月板及侧副韧带损伤。患者的活动需求主要为低到中度，所有患者的交叉韧带撕裂最初均采用非手术治疗。通过测量矢状深度和轴向高度来计算一个商数，以描述股骨髁的几何形状。测量结果具有可重复性，观察者内和观察者间的相关系数为0.89 - 0.98。在随访5（3 - 6）年后，16例患者出现功能障碍并接受了重建手术。其余84例患者没有任何严重的功能限制，但有些患者降低了活动水平。在非手术治疗失败的患者中，发现股骨髁的关节几何形状存在个体差异，其形状更接近球形。我们的研究结果表明，关节几何形状对前交叉韧带损伤后的功能很重要。
