We share our initial experience of total knee arthroplasty (TKA) using customized cutting block technology in 32 TKAs from May 2010 to March 2011. Ten of these patients had prior TKA done on the other side using conventional or navigation-assisted TKA. Customized cutting blocks were generated for each of the knee using preoperative magnetic resonance imaging of knee and long-leg weight-bearing radiographs. At 6 weeks, long-leg radiographs were obtained to evaluate the coronal alignment. There were no adverse intraoperative events. Twenty-nine of the 32 knees had a mechanical axis restored to within 3°° of neutral. Of 10 patients with prior TKA without custom-fit technology, the mean blood loss and the mean skin-to-skin time was found to be lower in knees that had undergone custom-fit TKA. We conclude that this technology can be safely used in most of the cases of osteoarthritis.
我们分享了 2010 年 5 月至 2011 年 3 月期间使用定制截骨块技术进行的 32 例全膝关节置换术（TKA）的初步经验。其中 10 例患者对侧膝关节曾接受过传统或导航辅助 TKA 治疗。使用膝关节术前磁共振成像和负重全长下肢 X 线片为每个膝关节生成定制截骨块。术后 6 周时，获取下肢全长 X 线片以评估冠状面的对线情况。术中未发生不良事件。32 例膝关节中有 29 例机械轴恢复到中立位 3°以内。在 10 例无定制拟合技术的既往 TKA 患者中，接受定制拟合 TKA 的膝关节的平均失血量和皮肤到皮肤的平均时间较低。我们得出结论，该技术在大多数骨关节炎病例中都可以安全使用。
