Between September 1992 and December 1996 we reviewed three transverse displaced fractures of the patella occuring in 1,320 ACL reconstructions using bone-patellar tendon-bone autograft. All the patients suffered local injury to the donor knee between 8 and 12 weeks postoperatively. Immediate rigid fixation using single or double anterior tension band allowed early mobilization and full weight bearing. Between 6 and 9 months after fracture, the screws and the wire were removed and the grafts tested. Results of the pivot shift and Lachman test under anesthesia were negative and arthroscopic visualisation showed the graft to be intact. Postoperative assessment included the Lysholm and Tegner scales, the International Knee Documentation Committee Evaluation form (IKDC), KT-1000 arthrometer, and isokinetic dynamometer strength testing. No significant differences in the final outcome were noted between reconstructions complicated by patellar fracture and normal ACL reconstructions.
在1992年9月至1996年12月期间，我们回顾了1320例采用骨-髌腱-骨自体移植物进行前交叉韧带重建手术中发生的3例髌骨横行移位骨折。所有患者均在术后8至12周时供体膝关节受到局部损伤。采用单根或双根前方张力带进行即刻坚强固定，可实现早期活动和完全负重。骨折后6至9个月，取出螺钉和钢丝并对移植物进行检测。麻醉下的轴移试验和Lachman试验结果均为阴性，关节镜检查显示移植物完整。术后评估包括Lysholm和Tegner评分量表、国际膝关节文献委员会评估表（IKDC）、KT-1000关节测径仪以及等速测力计肌力测试。在伴有髌骨骨折的重建手术与正常前交叉韧带重建手术之间，最终结果未发现显著差异。
