To evaluate whether medial knee support (MKS) in seating systems aggravates hip displacement in children with cerebral palsy (CP).
Retrospective chart review.
Rehabilitation department of tertiary university hospital.
Children with CP (N=76) using seating systems (intervention group, n=42; mean age 6.86y) and using regular wheelchairs (control group, n=34; mean age 8.15y).
The intervention group was provided with a seating system with MKS. We enrolled children who did not use a seating system in the control group, retrospectively.
By radiographic images, Reimer's migration index (MI), lateral center edge angle (CEA), and femur neck shaft angle (NSA) were measured. We compared the demographic data, clinical variables, and radiographs between the 2 groups.
In the intervention group, there was a significant deterioration in the MI, from 26.89% to 44.18% after using the system (P<.001). The progression of MI was 14.72% and 7.82% per year in the intervention and control groups, respectively (P=.016).
We should consider the possibility that seating systems with MKS may exacerbate hip displacement in children with CP.
评估座椅系统中的内侧膝支撑（MKS）是否会加重脑瘫（CP）儿童的髋关节移位。
回顾性图表审查。
三级大学医院康复科。
使用座椅系统的 CP 儿童（干预组，n=42；平均年龄 6.86 岁）和使用常规轮椅的儿童（对照组，n=34；平均年龄 8.15 岁）。
干预组配备了带有 MKS 的座椅系统。我们回顾性地招募了未使用座椅系统的对照组中的儿童。
通过影像学图像，测量 Reimer 的迁移指数（MI）、外侧中心边缘角（CEA）和股骨颈干角（NSA）。我们比较了两组之间的人口统计学数据、临床变量和影像学结果。
在干预组中，使用系统后 MI 从 26.89%显著恶化至 44.18%（P<.001）。干预组和对照组的 MI 每年分别增加 14.72%和 7.82%（P=.016）。
我们应该考虑座椅系统中的 MKS 可能会加重 CP 儿童的髋关节移位的可能性。
