目的:本研究通过 MRI 比较髌韧带内缘和后交叉韧带止点连线的垂线(AA)、胫骨后髁轴线(PC)、胫骨前髁轴线(AC)、胫骨经髁线(MMLD)、髌韧带中内1/3和后交叉韧带止点连线的垂线(BB)作为胫骨假体旋转对线参考标志与股骨外髁髁上线的关系及差异程度,分析作为胫骨假体旋转参考线的优劣,并进一步研究膝关节内翻畸形时是否会发生变异,确定最为理想的胫骨假体旋转参考标志。方法:正常膝关节30例,膝内翻30例,扫描 MRI 后测量股骨外髁髁上轴(STEA)与5条胫骨假体旋转轴之间的夹角并行组内组间比较。结果:正常组 AA、PC、AC、MMLD、BB 与 STEA 的夹角分别为(-1.48±2.38)°、(-6.16±4.53)°、(6.45±5.24)°、(-5.08±4.99)°、(3.24±2.68)°,内翻组各夹角分别为(-1.88±2.21)°、(-3.13±4.66)°、(11.13±5.72)°、(4.11±4.15)°、(5.12±4.87)°。 AA 与 STEA 交角组间比较 P >0.05,无统计学意义,其余夹角组间比较 P <0.05,具有统计学意义。结论:髌韧带内侧缘与后交叉韧带止点中点解剖标志定位基本不受骨性关节炎伴膝关节内翻畸形影响,AA 轴作为胫骨假体旋转参考线可靠,可提高手术的准确度。
目的:本研究通過 MRI 比較髕韌帶內緣和後交扠韌帶止點連線的垂線(AA)、脛骨後髁軸線(PC)、脛骨前髁軸線(AC)、脛骨經髁線(MMLD)、髕韌帶中內1/3和後交扠韌帶止點連線的垂線(BB)作為脛骨假體鏇轉對線參攷標誌與股骨外髁髁上線的關繫及差異程度,分析作為脛骨假體鏇轉參攷線的優劣,併進一步研究膝關節內翻畸形時是否會髮生變異,確定最為理想的脛骨假體鏇轉參攷標誌。方法:正常膝關節30例,膝內翻30例,掃描 MRI 後測量股骨外髁髁上軸(STEA)與5條脛骨假體鏇轉軸之間的夾角併行組內組間比較。結果:正常組 AA、PC、AC、MMLD、BB 與 STEA 的夾角分彆為(-1.48±2.38)°、(-6.16±4.53)°、(6.45±5.24)°、(-5.08±4.99)°、(3.24±2.68)°,內翻組各夾角分彆為(-1.88±2.21)°、(-3.13±4.66)°、(11.13±5.72)°、(4.11±4.15)°、(5.12±4.87)°。 AA 與 STEA 交角組間比較 P >0.05,無統計學意義,其餘夾角組間比較 P <0.05,具有統計學意義。結論:髕韌帶內側緣與後交扠韌帶止點中點解剖標誌定位基本不受骨性關節炎伴膝關節內翻畸形影響,AA 軸作為脛骨假體鏇轉參攷線可靠,可提高手術的準確度。

Objective To compare the difference between a vertical line (AA) drawn to the line connecting the inner edge of the patellar tendon with the mid-point of the ending point in the posterior cruciate ligament, tibial posterior condylar line (PC), tibial plateau anterior line (AC), the maximal mediolateral distance (MMLD) and a vertical line (BB) drawn to aligning the mid-point of ending point in the posterior cruciate ligament with the medial 1 / 3 of the patellar tendon relative to the surigical transepicondylar axis (STEA) by MRI, and to explore a reliable reference to determine tibial component rotation in total knee arthroplasty , and whether it will change in knees with varus deformity. Methods Thirty healthy volunteers (Group1) and thirty osteoarthritis patients (Group2) were enrolled in this study. The angles were measured among the five tibial rotation axes and STEA after MRI. Results The angles were (-1.48 ± 2.38)°, (6.16 ± 4.53)°, (6.45 ± 5.24)° ,(5.08 ± 4.99)° and (3.24 ± 2.68)° respectively in group 1 and (-1.88 ± 2.21)°, (-3.13 ± 4.66)°, (11.13 ± 5.72)°, (4.11 ± 4.15)° and (5.12 ± 4.87)° respectively in group 2. The angle between AA and STEA was not affected by varus deformity (P > 0.05), but the others were (P < 0.05). Conclusion The angle between AA and STEA is the smallest which is used to determine tibial component rotation in knees with varus deformity is the most reliable one.
