An original case of bilateral knee flexion of sixty degrees is reported in a twenty-four year old mean, with a beta-thalassemia diagnosed at three years old. The defect of straightening is the result of premature epiphysis fusion, only posterior in this case, and affecting preferentially the tibia. That is the reason why the flexion has been corrected by a bilateral tibial soustraction osteotomy, under the tibial tuberosity. The consolidation of the osteotomies has been obtained without any complications, with a complete extension and normal walk in a man moving only with a wheelchair before surgery. No similar case seems to be described in this kind of pathology.
本文报道了一例24岁男性双侧膝关节屈曲60度的病例，该患者三岁时被诊断为β地中海贫血。伸直障碍是由于骨骺过早融合所致，在本病例中仅为后侧，且优先影响胫骨。这就是为什么通过在胫骨结节下方进行双侧胫骨截骨术来矫正屈曲的原因。截骨术顺利愈合，未出现任何并发症，术前只能依靠轮椅活动的患者术后实现了完全伸直并能正常行走。在这类病理情况下，似乎尚未有类似病例的描述。
