There remains a lack of consensus regarding the necessity of implant augmentation or fixation after intralesional curettage in giant cell tumor of bone (GCTB) around the knee. This study assessed whether cementation alone is effective and safe in GCTB with a non-fracture around the knee. We retrospectively examined clinical data from 14 GCTB patients treated from 2012 to 2022. Outcome parameters were Musculoskeletal Tumor Society (MSTS) score, postoperative fracture, metastases, recurrence and complications. Of the 14 GCTB cases examined, 10 were at the distal femur and four were at the proximal tibia. Mean patient age was 32 years, and follow-up time was 61 months. Mean tumor size was 61 × 79 × 50 mm, and MSTS score was 89.2%. There were no cases of postoperative fracture. Defect reconstruction with cementation alone may be strong enough to provide immediate stability and prevent postoperative fracture in GCTB around the knee.
对于膝关节周围骨巨细胞瘤（GCTB）行病灶内刮除术后是否有必要进行植入物增强或固定，目前仍缺乏共识。本研究评估了单纯骨水泥填充在膝关节周围无骨折的GCTB中是否有效且安全。我们回顾性分析了2012年至2022年期间接受治疗的14例GCTB患者的临床资料。观察指标包括肌肉骨骼肿瘤学会（MSTS）评分、术后骨折、转移、复发及并发症。在检查的14例GCTB病例中，10例位于股骨远端，4例位于胫骨近端。患者平均年龄为32岁，随访时间为61个月。肿瘤平均大小为61×79×50mm，MSTS评分为89.2%。无术后骨折病例。单纯采用骨水泥填充进行缺损重建可能足以提供即时稳定性，并预防膝关节周围GCTB的术后骨折。
