摘　　要：目的探讨髌腱-股骨外侧髁撞击综合征(PT-LFCFS)的MRI表现。方法回顾性收集经临床证实26例PT-LFCFS患者(33个部位)(PT-LFCFS组)的MRI及临床资料,对PT-LFCFS的MRI表现及髌股关节解剖发育进行总结、测量,并与30例健康志愿者(对照组)比较。结果26例PT-LFCFS患者均有不同程度前膝慢性疼痛、不适及Hoffa脂肪垫外上份水肿,7例患者双膝关节同时发病(26.9%)。与对照组相比,PT-LFCFS组在髌骨形态方面差异无统计学意义(P>0.05);PT-LFCFS组股骨滑车形态以C型为主,常伴有滑车面不对称及高位髌骨(P<0.05);PT-LFCFS组滑车沟角较大,外侧滑车倾斜度较小,滑车沟深度较浅(P<0.05)。33个部位中,6个髌股关节软骨损伤,2个髌腱变性,2个髌内侧支持带损伤。结论PT-LFCFS患者部分双侧发病,并存在滑车发育不良、髌骨高位等解剖变异,常伴随Hoffa脂肪垫水肿及邻近结构损伤。Objective To explore the MRI features of patellar tendon-lateral femoral condyle friction syndrome(PT-LFCFS).Methods Twenty-six cases PT-LFCFS(totally 33 lesions)(PT-LFCFS group)confirmed by clinic were analyzed retrospectively.Meanwhile,30 normal healthy volunteers served as the control group.All cases were perfromed knee joint MRI scan.The MRI features of PT-LFCFS were summarized,and assessed the anatomical development in patellofemoral joint.Results The patients with PT-LFCFS(26 cases),who had chronic pain and discomfort in anterior knee,Hoffa’s fat pad edema in the upper lateral side were observed in MRI.Both knees clinical symptoms were observed in 7 patients(26.94%).Compared with control group,there was no significant differences in patellar morphology(P>0.05);The patellar morphology main morphology was C type in PT-LFCFS group(P<0.05),who more likely had trochlear facet and asymmetry patellar alta(P<0.05).PT-LFCFS group had greater sulcus and smaller lateral trochlear inclination,shallow trochlear depth(P<0.05).There were 6 lesions cartilage injuries,2 lesions patellar tendon degeneration and 2 lesions medial patellar retinata injuries in PT-LFCFS group.Conclusion Most PT-LFCFS patients have bilateral disease,coexists with anatomical variations such as trochlear dysplasia and patella alta,often accompanied by Hoffa’s fat pad and adjacent structural.
