Abstract：
METHODS: A 19-year-old man underwent arthroscopic posterior glenoid reconstruction with a distal tibia allograft (DTA) after failing 2 posterior, soft-tissue instability surgeries. Although he experienced near-complete resolution of symptoms and return to sport, graft resorption was noted 7 months postoperatively. The patient underwent revision surgery for screw removal.
CONCLUSIONS: Graft resorption has not previously been reported in the setting of arthroscopic DTA use for posterior instability. It is believed that stress shielding contributed to resorption. In such situations, screw removal may be warranted. Consideration of alternative fixation techniques and additional investigation into the causes, clinical significance, and optimal management of posterior DTA resorption are warranted.

摘要：
方法：一名19岁男子接受关节镜下后方关节盂重建与胫骨远端同种异体移植（DTA）后2后失败，软组织不稳定手术。尽管他的症状几乎完全消退并恢复运动，术后7个月注意到移植物吸收。患者接受了翻修手术以移除螺钉。
结论：在关节镜下使用DTA治疗后路不稳定的情况下，以前没有报道过移植物吸收。据信应力屏蔽有助于再吸收。在这种情况下,可能需要拆卸螺钉。考虑替代固定技术并对原因进行额外调查，临床意义,和后DTA吸收的最佳管理是必要的。
