The composite tissue flap of the descending genicular vessels with the adductor magnus tendon is a newly developed, reliable method to repair the Achilles tendon and relevant skin defects. The aim of this study was to evaluate the anatomy of the adductor magnus tendon-descending genicular artery bone flap, and the feasibility and value for the repair of the Achilles tendon and relevant skin defects. There were 34 adult specimens used for the anatomy of this flap. The descending genicular artery originates 10.5 ± 1.6 cm above the adductor tubercle, with a diameter of 1.8 ± 0.6 mm and a length of 1.2 ± 0.5 cm. Its articular branch is distributed in the adductor magnus tendon and the medial condyle of the femur. The saphenous branch has a diameter of 1.1 ± 0.3 mm and is distributed in the skin of the upper medial calf. A total of 16 cases of trauma-induced Achilles tendon damage and calcaneus and skin defects were repaired with the vascularized adductor magnus tendon bone flap, including the reconstruction of Achilles tendon insertion and repair of relevant skin defects. All of the composite tissue flaps were viable, the skin sensation of the flaps was recovered, and all patients walked with a normal gait. Our results suggested that the adductor magnus tendon-descending genicular artery bone flap is an alternative method to repair composite tissue defects of the Achilles tendon.
膝降血管复合组织瓣联合大收肌腱修复跟腱及相关皮肤缺损是一种新的、可靠的方法。本研究旨在评估大收肌腱-膝降动脉骨瓣的解剖结构，探讨其修复跟腱及相关皮肤缺损的可行性和价值。共使用 34 个成人标本进行了该皮瓣的解剖学研究。膝降动脉在收肌结节上方 10.5±1.6cm 处起源，直径 1.8±0.6mm，长度 1.2±0.5cm。其关节支分布于大收肌腱和股骨内髁。隐支直径 1.1±0.3mm，分布于小腿中上段皮肤。共 16 例创伤性跟腱损伤及跟骨和皮肤缺损患者采用带血管蒂的大收肌腱骨瓣修复，包括跟腱止点重建和相关皮肤缺损修复。所有复合组织瓣均存活，皮瓣感觉恢复正常，所有患者均能正常行走。我们的结果表明，大收肌腱-膝降动脉骨瓣是修复跟腱复合组织缺损的一种替代方法。
