BACKGROUND:Studies have reported that the bone bridge and bone plug for meniscal alograft transplantation show better outcomes than simple soft tissue suture, but there are rare studies concerning the comparison of their fixation effects. OBJECTIVE:To compare the clinical effects of bone bridge and bone plug in meniscal alograft transplantation. METHODS:Eighteen patients undergoing arthroscopy-assisted meniscal alograft transplantation were enroled, including nine cases of bone plug fixation and nine cases of bone bridge fixation. Symptoms, physical examination, visual analog scale, Lysholm and Tegner scores were used to evaluate the clinic outcome. Every 6 months post operation, the signal and morphological changes of alograft meniscus was observed with MRI for each patient. RESULTS AND CONCLUSION:Al of the 18 patients were folowed up for 12-36 months after transplantation. No complications, absence of knee pain and effusion, and disappearance of the discomfort within the meniscectomy compartments after prolonged activity during folow-up period were found in al patients. The patients were competent of daily life and sports activity. The visual analog scale, Lysholm and Tegner scores were significantly increased after transplantation. MRI showed that the vicariousness and livability of the alograft menisci appeared within 1 year post operation. The safety and feasibility of the arthroscopy-assisted meniscal alograft transplantation were approved. Knee pain, knee effusion and joint stability and function were improved after arthroscopic-assisted alograft meniscus transplantation, and there was no difference between the clinical curative effects of the two kinds of fixed methods.%背景：文献报道，半月板移植骨桥及前后角骨栓固定较单纯软组织缝合固定效果更好，但关于骨桥与骨栓二者固定疗效比较的报道较少。目的：对比分析骨桥与骨栓固定同种异体半月板移植的临床效果。方法：18例外侧半月板切除后接受关节镜下同种异体外侧半月板移植患者，其中9例采用骨栓法、9例采用骨桥法行外侧半月板移植。随访采用症状询问，体征检查，目测类比疼痛评分、Lysholm和Tegner评分进行综合分析。所有患者平均每半年进行1次MRI 检查，观察膝关节半月板移植后形态状态及信号改变。结果与结论：18例患者均进行了12-36个月的随访。所有患者随访时关节活动度均正常，均无明显的膝关节疼痛和肿胀，可以胜任日常活动和体育锻炼，无并发症出现。半月板移植后目测类比疼痛评分、Lysholm、Tegner评分均较移植前明显提高。MRI检查提示移植半月板移植后1年时替代存活很好。结果表明关节镜下的同种异体半月板移植安全可行，半月板移植可缓解半月板切除后出现的关节疼痛、肿胀等症状，骨桥固定与骨栓固定法临床疗效无明显差异。
