Comparison of motion-triggered cine magnetic resonance (MR) imaging and conventional radiographs for the assessment of operative results of patellar realignment.
Fifteen patients with recurrent patellar dislocation or patellar subluxation were evaluated with conventional axial radiographs before and after realignment surgery by measuring the congruence angle (CA), lateral patellofemoral angle (LPFA), and lateral displacement (d). In eight patients the patellofemoral joint was additionally evaluated pre- and postoperatively with motion-triggered cine MR imaging by determining the bisect offset (BSO), lateral patellar displacement (LPD), and patellar tilt angle (PTA).
Significant differences between the pre- and postoperative measurements were found for all MR imaging parameters (BSO, LPD, PTA: p<0.01) but not for the conventional X-ray parameters (CA: p = 0.70, LPFA: p = 0.56; d: p = 0.04). Motion-triggered cine MR imaging was superior to conventional tangential radiographs for assessing the effectiveness of patellar realignment surgery.
比较运动触发的电影磁共振成像（MR）与传统X线片对髌骨重新排列手术效果的评估。
15例复发性髌骨脱位或半脱位患者在重新排列手术前后接受传统的轴位X线片检查，测量适合角（CA）、髌股外侧角（LPFA）和外侧移位（d）。8例患者还在手术前后通过运动触发的电影磁共振成像评估髌股关节，测定平分偏移（BSO）、髌骨外侧移位（LPD）和髌骨倾斜角（PTA）。
所有磁共振成像参数（BSO、LPD、PTA：p<0.01）术前和术后测量有显著差异，但传统X线参数（CA：p = 0.70，LPFA：p = 0.56；d：p = 0.04）无显著差异。运动触发的电影磁共振成像在评估髌骨重新排列手术效果方面优于传统的切线位X线片。
