Infection after total knee arthroplasty (TKA) is a devastating complication, and two-stage reimplantation has evolved as an effective treatment option. This study was undertaken to compare the clinical results and radiological changes associated with static or mobile cement spacer placement for the treatment of infected TKA. Between July 2000 and February 2007, 36 consecutive patients were treated by two-stage reimplantation using antibiotic-impregnated cement spacers (AICS) for infected TKAs. Static spacers were used in 20 knees and mobile spacers in 16 knees. Clinical outcomes included success rates of TKR revisions, ranges of motion (ROM), and Hospital for Special Surgery knee scores (HSS), pain and function scores of the Knee Society (KS), joint exposure methods, and bone loss. In this study, mobile spacers provided better ranges of motion and functional knee scores without concomitant increases in infection rate and bone loss in the initial and mid-term periods.
全膝关节置换术后感染是一种破坏性的并发症，而两阶段再植入已发展成为一种有效的治疗选择。本研究旨在比较使用固定或活动型水泥间隔器治疗感染性全膝关节置换术的临床结果和影像学变化。2000 年 7 月至 2007 年 2 月，36 例连续患者采用抗生素浸渍水泥间隔器（AICS）进行两阶段再植入治疗感染性 TKA。20 例膝关节采用固定间隔器，16 例膝关节采用活动间隔器。临床结果包括 TKR 翻修成功率、活动范围（ROM）和特种外科医院膝关节评分（HSS）、膝关节学会（KS）疼痛和功能评分、关节显露方法和骨丢失。在本研究中，活动间隔器提供了更好的活动范围和功能膝关节评分，而在初始和中期阶段，感染率和骨丢失没有增加。
