摘要
目的测量国人膝关节后外侧角(posterolateral corner of the knee,PLC)中外侧副韧带(lateral collateral ligament,LCL)、腘肌腱(popliteus tendon,PT)和腘腓韧带(popliteofibular ligament,PFL)止点的解剖学数据,为临床PLC重建术中骨隧道的定位提供解剖学依据。方法取30个成年膝关节甲醛固定标本,其中男14例,女16例;年龄45～71岁,平均55岁。对PLC结构进行观察,测量LCL、PT和PFL附丽部中心点与股骨外上髁和腓骨茎突最近点的位置关系以及附丽部的横截面积,并将每个标本测量值进行标准化。结果股骨侧:LCL附丽部中心点在股骨外上髁近端(1.27±3.10)mm、后方(2.99±1.29)mm,PT附丽部中心点在股骨外上髁远端(8.85±3.38)mm、后方(3.83±1.95)mm。腓骨侧:LCL附丽部中心点在腓骨茎突最近点远端(10.56±2.17)mm、前方(7.51±1.81)mm,PFL附丽部中心点在腓骨茎突最近点远端(1.31±0.55)mm、前方(0.49±1.36)mm。LCL和PT在股骨上附丽部的横截面积分别为(44.96±13.29)mm2和(52.52±11.93)mm2,LCL和PFL在腓骨上附丽部的横截面积分别为(35.93±11.21)mm2和(14.71±6.91)mm2。结论 LCL、PFL及PT的附丽部中心点具有稳定性。
Objective To obtain the anatomical data of the insertions of the lateral collateral ligament（LCL）,popliteus tendon（PT）,and popliteofibular ligament（PFL） for the posterolateral corner of the knee（PLC） reconstruction.Methods Thirty human cadaveric knees were chosen to observe the structure of PLC,including 14 males and 16 females with an average age of 55 years（range,45-71 years）.The insertions of LCL,PT,and PFL were identified,then the distances from the centers of the insertions to specific bony landmarks were measured,which were lateral epicondyle,the most proximal point on the styloid process and the most anterior point on the anterior surface of the fibular head.Normalization processing of the actual numerical values from each knee was performed.Results The center of the LCL insertion was at the site of（1.27 ± 3.10） mm proximal and（2.99 ± 1.29） mm posterior to the lateral epicondyle of the femur respectively,and the center of the PT insertion was at the site of（8.85 ± 3.38） mm distal and（3.83 ± 1.95） mm posterior to the lateral epicondyle of the femur respectively.The center of the LCL insertion was at the site of（10.56 ± 2.17） mm distal and（7.51 ± 1.81） mm anterior to the nearest point of the fibular styloid respectively,and the center of the PFL insertion was at the sites of（1.31 ± 0.55） mm distal and（0.49 ± 1.36） mm anterior to the nearest point of the fibular styloid respectively.The cross-sectional area of the insertions of femur was（44.96 ± 13.29） mm2 for the LCL and（52.52 ± 11.93） mm2 for the PT,respectively;the cross-sectional area of the insertions of fibula was（35.93 ± 11.21） mm2 for the LCL and（14.71 ± 6.91） mm2 for the PFL,respectively.Conclusion The LCL,PT,and PFL have a consistent pattern of insertion.
