Isolated unilateral congenital patellar tendon absence is a rare condition that has not been well described. We report on 2 patients with congenital patellar tendon absence that underwent soft-tissue reconstruction of their patellar tendon. We present the clinical and radiographic features, surgical management with both single-stage and multistage approaches, and postoperative outcomes for the treatment of this condition.
Soft-tissue reconstruction of the patellar tendon led to satisfactory outcomes, providing active knee extension and improved ambulation in both cases. In cases of significant superior migration, multiple procedures may be required to mobilize the patella to an appropriate position.
孤立性单侧先天性髌腱缺失是一种罕见的疾病，尚未得到很好的描述。我们报告了 2 例先天性髌腱缺失患者，他们接受了髌腱软组织重建。我们介绍了这种疾病的临床和影像学特征、单一阶段和多阶段手术管理以及术后结果。
髌腱软组织重建可获得满意的结果，在 2 例患者中均提供了主动伸膝和改善了步行能力。在髌上严重迁移的情况下，可能需要多次手术才能将髌骨移动到适当的位置。
