The purpose of this study is to determine if children more severely involved with cerebral palsy respond as well to rectus transfer and hamstring surgery as those with less severe involvement. Ninety-nine children were classified as independent community ambulators, crutch/walker-dependent community ambulators, or household/exercise ambulators. Maximum knee extension in stance and total range of knee motion in gait increased following surgery in all groups. Peak knee flexion in swing was maintained in the independent group only, but timing of knee flexion in swing improved in all groups...

The purpose of this study was to evaluate the long-term results of rectus femoris transfer in cerebral palsy children with stiff-knee gait. Thirty-eight affected limbs in 24 children were evaluated preoperatively and 1 year postoperatively by gait analysis, with 26 limbs in 18 patients having final study, averaging 4.6 years postoperatively. Functional ambulatory status was evaluated based on Hoffer's criteria on ambulation. There were statistically significant improvements of 9.8 degrees in maximum swing-phase knee flexion and 7...

BACKGROUND: 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...

OBJECTIVES: Outcomes of single-event bilateral multilevel orthopedic surgery in children with cerebral palsy were retrospectively investigated by physical findings, and gross motor function measurement (GMFM) score in all patients and additionally by joint kinematics, and time-distance parameters in ambulatory patients. PATIENTS AND METHODS: A total of 24 patients (17 ambulatory; 7 non ambulatory; mean age 12 years; range 5 to 19 years) treated with multilevel orthopedic surgery between December 2003 and December 2005 were included in the study...

BACKGROUND: Although several studies have reported on the outcomes of rectus femoris transfer (RFT), few have investigated the multiple factors that could affect the results. Therefore, we evaluated the outcomes of RFT and analyzed factors that influence improvement and annual change in knee motion after surgery in patients with cerebral palsy (CP). METHODS: We reviewed ambulatory patients with CP who were followed up after they had undergone RFT as part of a single-event multilevel surgery (SEMLS) and who had undergone preoperative and postoperative three-dimensional (3D) gait analysis between January 1995 and December 2012...

BACKGROUND: Stiff gait resulting from rectus femoris dysfunction in cerebral palsy commonly is treated by distal rectus femoris transfer (DRFT), but varying outcomes have been reported. Proximal rectus femoris release was found to be less effective compared with DRFT. No study to our knowledge has investigated the effects of the combination of both procedures on gait. QUESTIONS/PURPOSES: We sought to determine whether an additional proximal rectus release affects knee and pelvic kinematics when done in combination with DRFT; specifically, we sought to compare outcomes using the (1) range of knee flexion in swing phase, (2) knee flexion velocity and (3) peak knee flexion in swing phase, and (4) spatiotemporal parameters between patients treated with DRFT, with or without proximal rectus release...

The objectives of this study were to investigate the anatomical relationship between the proximal adductor longus (AL) and rectus abdominis muscles and to determine whether unilateral loading of AL results in strain transmission across the anterior pubic symphysis to the contralateral distal rectus sheath. Bilateral dissections were conducted on 10 embalmed cadavers. Strain transfer across the pubic symphysis was examined on seven of these cadavers. An AL contraction was simulated by applying a controlled load in the direction of its proximal tendinous fibers, and the resultant strain in the contralateral distal rectus sheath was measured using a foil-type surface mounted microstrain gage...

BACKGROUND: Distal rectus femoris transfer is a widely accepted and effective treatment for children with cerebral palsy presenting with stiff knee gait. Previous research has reported improvement in knee arc of motion regardless of transfer site; however, sample sizes and patient function were unmatched in these studies. The purpose of this study was to compare the outcomes of children with cerebral palsy treated with a distal rectus femoris transfer for stiff knee to 1 of 3 sites: medial to the semitendinosus (ST), medial to the sartorius (SR), or lateral to the iliotibial band (ITB)...
