目的:探讨定制国产铰链膝关节肿瘤假体治疗胫骨近端骨巨细胞瘤的临床疗效。方法:对收治的10例胫骨近端骨巨细胞瘤行瘤段切除后应用国产铰链型膝关节肿瘤假体重建患者进行回顾性研究。所有患者均为初次就诊。采用骨与软组织肿瘤协会评分(MSTS)标准评定膝关节功能。结果:10例患者均获得随访,平均随访时间41.4个月(12~80个月)。无死亡、无局部复发及远处转移病例。膝关节伸直0°,屈膝70°~100°。MSTS为(25.4±4.8)分,优良率为90%。无切口并发症及深部感染。所有病例均未发现明显假体松动、下沉。结论:胫骨近端骨巨细胞瘤行瘤段切除后应用定制国产铰链膝关节肿瘤假体重建功能,临床效果满意。
Objective: To investigate the curative effect of customized domestic knee joint prosthesis on treatment of giant cell tumor of proximal tibia. Methods: Ten cases of resected giant cell tumor of proximal tibia were treated by resection of the prosthesis with domestic hinge type knee arthroplasty. All patients are on first visit. Knee joint function was assessed using the Association of Bone and Soft Tissue Society (MSTS) criteria. Results: All 10 patients were followed up for an average of 41.4 months (range, 12 to 80 months). No death, no local recurrence and distant metastasis. Knee extension 0 °, knees 70 ° ~ 100 °. MSTS was (25.4 ± 4.8) points, excellent and good rate was 90%. No incision complications and deep infection. All cases did not find significant loose prosthesis, sinking. Conclusion: Tumor resection using a custom made domestic hinge knee prosthesis after resection of giant cell tumor of proximal tibia has satisfactory clinical effect.
