Rectus femoris transfer (RFT) is a treatment option for children with cerebral palsy (CP) who exhibit a stiff-knee gait pattern. The rectus femoris muscle is transferred to different sites to overcome problems such as tripping and falling. Indications for RFT often include preoperative decreased knee range of motion (KROM) during swing phase, reduced peak knee flexion in swing (PKFSW), abnormal rectus femoris firing patterns on electromyography recordings, and a positive Duncan-Ely test. This study investigated the effect of different RFT sites on kinematic outcome variables and evaluated the relationship between commonly used preoperative surgical indicators and postoperative changes in kinematics. ⋯ Level 3.

Hinge abduction is widely accepted as a poor prognostic factor in Legg-Calvé-Perthes disease (LCPD), whereas the exact definition of hinge abduction remains ill defined. The purpose of this diagnostic study was to refine the definition of hinge abduction in LCPD using conventional hip arthrography under general anesthesia. ⋯ Level II (diagnostic study, development of diagnostic criteria on the basis of consecutive patients).
