Abstract：
BACKGROUND: Isolated Patellar Aplasia Hypoplasia is a very rare autosomal dominant disorder. Its treatment depends on the clinical manifestations that can vary widely. The lack of active extension, which can be responsible for frequent falls due to a knee instability, is the most frequent and disabling manifestation. We report an original technique that is a modification of the Galeazzi technique for recurrent dislocation of the patella to gain active extension in case of PTLAH.
METHODS: A 7-year-old Caucasian boy with isolated Patellar Aplasia Hypoplasia and an extension lag of the right knee has been treated by a modified Galeazzi technique. The tendons of the semi-tendinous and gracilis muscles have been harvested and their distal insertion was kept intact. Both tendons were fixed over the top of the patella to restore knee active extension. After 6 years of follow up the patient is symptom free with a strong active extension of the operated knee.
CONCLUSIONS: Reconstruction of isolated hypoplasia of the patella by a modified Galeazzi procedure is a safe and reliable technique for skeletally immature patients offering satisfying long-term outcomes.

摘要：
背景：孤立性髌骨发育不全是一种非常罕见的常染色体显性遗传病。其治疗取决于可能差异很大的临床表现。缺乏积极的延伸，这可能是由于膝盖不稳定而经常跌倒的原因，是最常见和致残的表现。我们报告了一种原始技术，该技术是对Galeazzi技术的改进，用于在PTLAH的情况下使the骨反复脱位以获得主动延伸。
方法：一名7岁的白人男孩，患有孤立性髌骨发育不全和右膝伸展滞后，已通过改良的Galeazzi技术治疗。已收获了半腱肌和gra肌的肌腱，并且它们的远端插入保持完整。将两个肌腱固定在髌骨顶部以恢复膝关节主动伸展。经过6年的随访，患者无症状，并且膝关节的手术能力很强。
结论：改良Galeazzi手术重建孤立性髌骨发育不全是一种安全可靠的技术，适用于骨骼未成熟患者，可提供令人满意的长期结果。
