摘要目的 探讨前交叉韧带重建术后假体功能不全的影像特点.方法 同顾性分析24例韧带重建术后因功能不全而接受二次关节镜的患者,包括16例假体断裂,8例假体松弛.影像评价包括骨道关节内口的位置、韧带假体的MRI表现、骨关节病程度及相关并发症.假体断裂组和松弛组的骨道内口位置、MRI表现为断裂的比例及骨关节病等的比较,采用Fisher精确概率法比较.结果 断裂组中,2例股骨骨道关节内口位置异常,3例胫骨骨道关节内口位置异常;松弛组中,3例股骨骨道关节内口位置异常,4例胫骨骨道关节内口位置异常.两组间比较,股骨骨道关节内口位置异常(P=0.289)和胫骨骨道关节内口位置异常的比例(P=0.167)差异均无统计学意义.断裂组中,MRI正确诊断15例完全断裂,1例部分断裂表现为正常;松弛组中,4例表现为正常,其余4例在MRI上被诊断为假体断裂.两组在MRI上表现为断裂的比例差异存在统计学意义(P =0.028).断裂组中,14例可见骨关节病;松弛组中,5例可见骨关节病.两组骨关节病的比例差异无统计学意义(P=0.289).结论 假体断裂和假体松弛骨道关节内口位置异常和骨关节病的比例差异无统计学意义;MRI可以正确诊断绝大多数假体断裂,而部分假体松弛则容易被误诊为假体断裂. Objective To investigate the imaging features of anterior cruciate ligament(ACL) graft insufficiency.Methods X-Ray and MR imaging examinations in 24 consecutive patients who had ACL reconstructive graft insufficiency were retrospectively evaluated for tunnel position,osteoarthrosis and its related complications.Follow-up arthroscopy showed 16 graft tears and 8 graft laxities.Fisher exact test was used to compare tunnel malpositions,the proportion of graft tear on MRI and osteoarthrosis between graft tear group and graft laxity group.Results Two malpositions of tibial tunnel and 3 malpositions of femoral tunnel were seen in graft tear group.Three-malpositions of tibial tunnel and 4 malpositions of femoral tunnel were seen in graft laxity group.The proportion of tibial or femoral malposition showed no significant difference between the two groups(P =0.289,P =0.167).In graft tear group,15 complete graft tears were diagnosed correctly,1 partial tear was misdiagnosed as normal on MRI.In graft laxity group,4 grafts were diagnosed as normal and 4 were considered as graft tear on MRI.A significant difference was seen between the two groups (P = 0.028) in the proportion of graft tear diagnosed on MRI.Fourteen osteoarthrosis were seen in graft tear group and 5 in graft laxity group.No significant difference was seen between the two groups ( P =0.289) in the proportion of esteoarthrosis.Conclusion The proportions of tunnel malposition and osteoarthrosis showed no significant difference between the graft tear group and graft laxity group.Most graft tears can be diagnosed accurately on MRI,but some cases of graft laxity may be misdiagnosed for graft tear.
