We report two cases in which arthrodesed knees were revised to total arthroplasties after the use of soft-tissue expanders. Case 1 had had multiple operations on her knee and had been arthrodesed for septic arthritis two years earlier. Case 2 had had knee arthrodesis for severe osteoarthritis 18 years before revision. In both patients, tissue expanders were used to increase the soft tissues available for cover and to help to mobilise the extensor mechanism. The operations were made much easier, and in both patients a range of motion from 0 degrees to 90 degrees was achieved at operation.
我们报告了两例在使用软组织扩张器后，将膝关节融合术翻修为全关节置换术的病例。病例1的膝关节曾多次手术，两年前因化脓性关节炎行关节融合术。病例2在翻修前18年因严重骨关节炎行膝关节融合术。在这两名患者中，均使用了组织扩张器来增加可用于覆盖的软组织，并帮助动员伸肌机制。手术变得容易得多，两名患者在手术时均实现了从0度到90度的活动范围。
