To demonstrate the clinical and radiographic results of revision knee arthroplasty using a modular system manufactured in Brazil.
Between November 2010 and January 2017, 31 revision knee arthroplasties were performed in 30 patients, using the MB-V system. Patients were assessed clinically and radiographically after a minimum follow-up of two years using the following scores: Knee Society Score (KSS), Knee Society Score ‒ Function (KSS ‒ Function), and Knee Society Roentgenographic Evaluation System (KSRES).
Among the patients, 19 were women. The mean age at surgery was 68 years. The mean follow-up was 9.1 years. There was no aseptic loosening in this period. The mean values of KSS, KSS-function, and KSRES were, respectively, 82, 77, and less than 4. One patient evolved with postoperative flexion instability. Two knees became infected, requiring the removal of the prosthesis and implantation of spacers loaded with antibiotics. One patient developed arthrofibrosis. One patient had a dislocation with full medial collateral avulsion and had to be re-operated with an insert exchange to a CCK liner and medial collateral reconstruction as proposed by Krakow.
This implant had 93.5 % survivorship (no cases of aseptic failure) and good results in 27 out of 31 knees (87 % of the surgeries).
展示在巴西制造的模块化系统在膝关节翻修术中的临床和影像学结果。
2010 年 11 月至 2017 年 1 月，30 例患者中的 31 例接受了 MB-V 系统的膝关节翻修术。对患者进行了至少两年的随访，并使用以下评分进行了临床和影像学评估：膝关节协会评分（KSS）、膝关节协会评分-功能（KSS-功能）和膝关节协会 X 线评估系统（KSRES）。
在患者中，19 名女性。手术时的平均年龄为 68 岁。平均随访时间为 9.1 年。在此期间，没有发生无菌性松动。KSS、KSS-功能和 KSRES 的平均数值分别为 82、77 和低于 4。1 例患者术后出现屈曲不稳定。2 例膝关节感染，需要取出假体并植入载抗生素的间隔物。1 例患者发生关节纤维性变。1 例患者发生全内侧副韧带撕脱性脱位，需要进行翻修手术，更换 CCK 衬垫，并按 Krakow 提出的方法重建内侧副韧带。
该植入物的存活率为 93.5%（无无菌性失败病例），31 例膝关节中有 27 例（87%的手术）结果良好。
