Total ankle arthroplasty (TAA) has become one of the standard treatments for end-stage ankle arthritis. Long-term TAA survivorship is reported from 63% to 95%, with aseptic loosening being the most common mode of failure. Several studies have shown that low bone mineral density (BMD) of the hip affects the longevity of prosthetic implants. The role of Dual energy X-ray absorptiometry for TAA has not been established. The purpose of this review was to define the role of BMD in TAA outcomes and the role of Dual energy X-ray absorptiometry in measuring periprosthetic BMD. There is a paucity of information and published literature regarding the relationship between BMD and TAA. From attempting this systematic review, we hope to highlight that much of the focus in total ankle arthroplasty has emphasized implants and relatively little has focused on the quality of bone into which the prostheses are implanted.
全踝关节置换术（TAA）已成为终末期踝关节关节炎的标准治疗方法之一。据报道，TAA的长期生存率为63%至95%，无菌性松动是最常见的失败模式。多项研究表明，髋部低骨密度（BMD）会影响假体植入物的使用寿命。双能X线吸收法在TAA中的作用尚未确立。本综述的目的是确定BMD在TAA结果中的作用以及双能X线吸收法在测量假体周围BMD中的作用。关于BMD与TAA之间的关系，信息和已发表的文献很少。通过尝试进行这项系统综述，我们希望强调，全踝关节置换术中的大部分重点都放在了植入物上，而对假体植入部位的骨质质量关注相对较少。
