We sought to evaluate reoperation-free survival following I&D with modular component exchange of revision total joint arthroplasty (TJA).
Of revision TJAs from 2004 to 2012 (n = 4,166), 30 were I&D with modular component exchange after index revision for aseptic indications. Patients with (n = 12) and without (n = 18) reoperation for infection recurrence were analyzed.
Reoperation-free survival (60% at mean 4.8 year follow-up) improved with increased duration of antibiotic therapy (p = 0.0185), with maximum benefit at 2 years.
At least 2 years of antibiotic therapy should be administered after I&D with modular component exchange for acutely infected revision TJA.
Level III, retrospective comparative study.
我们试图评估在翻修全关节置换术(TJA)中进行切开引流及模块化组件更换后的无再次手术生存率。
在2004年至2012年的翻修TJA病例(n = 4166)中,30例因无菌性指征进行初次翻修后接受了切开引流及模块化组件更换。对有(n = 12)和无(n = 18)感染复发再次手术的患者进行了分析。
随着抗生素治疗时间的延长,无再次手术生存率(平均随访4.8年时为60%)有所提高(p = 0.0185),在2年时获益最大。
对于急性感染的翻修TJA,在切开引流及模块化组件更换后应给予至少2年的抗生素治疗。
III级,回顾性比较研究。
