Abstract Background Indications and cutoff value of deformities to determine surgical procedures for flexed knee gait are not clear. The aim was to determine the influence of none or mild, and moderate preoperative knee flexion contracture on the improvement of gait after orthopedic surgery in children with bilateral cerebral palsy (CP). Methods Inclusion criteria; bilateral CP, Gross Motor Function Classification System level I-III, and pre- and post operative-gait analysis. The 132 individuals identified were categorized into 2 groups based on the severity of knee flexion contracture (group 1: none or less than 11°; group 2: greater than or equal to 11°), and then matched according to the exact same soft tissue and/or bony orthopedic surgical procedures performed. The indication for surgery was to prevent progressive development of knee flexion contracture and stance phase flexed knee gait. Pre- and postoperative physical examination and gait analysis data were analyzed retrospectively. Results Sixty (30 + 30) children, with mean age 10.6 years in each group, were included. The average follow-up time was 17 months. Gait Deviation Index (GDI) improved in group 1 from mean 66 (SD 19) to 74 (15), p = 0.004, and in group 2 from 60 (13) to 69 (15), p = 0.001. Knee flexion in stance improved in group 1 from 21.4 (16.1) to 12.1 (16.0) degrees, p = 0.002, and in group 2 from 32.2 (14.2) to 17.0 (15.9), p = 0.001. Step length improved in both groups, p = 0.017 and p = 0.008, respectively. Only in group 2 significant improvement was noted in walking speed, p = 0.018 and standing function, Gross Motor Function Measure (GMFM-D), p = 0.001. Knee flexion contracture decreased in group 1 from mean 4.6 (5.3) to 2.1 (8.3) degrees, p = 0.071 and in group 2 from 17.2 (4.9) to 9.6 (9.3), p = 0.001. There was no statistical difference between groups in pre-post improvement of GDI or other variables, except GMFM-D. Conclusions Relative mild to moderate preoperative knee flexion contracture does not influence the short-term improvement of gait after orthopedic surgery in children with bilateral CP.

Underlying Mechanisms

Purpose: Synergistic neuro-excitability in the lower extremities may be related to gait disorders. This study aimed to report spontaneous changes after correcting knee flexion gait and discuss the underlying mechanisms. Methods: A prospective study of 23 children with cerebral palsy was conducted to assess postoperative changes in gross motor function, joint range of motion (ROM), and spasticity. Characteristics of children/limbs with spontaneous decrease in gastrocnemius spasticity were assessed. Results: In 10 patients (19 limbs) without gastrocnemius release, the Modified Ashworth scores in the gastrocnemius decreased in 6 limbs after 3 months and in 10 limbs after 6 months. Those limbs with spontaneous changes had worse preoperative knee flexion contracture than the limbs without spasticity changes (knee ROM limitation score 5.4 vs. 3.7, p = 0.026). Conclusions: Patients with knee flexion contracture recruited greater plantar flexion–knee extension couple to balance knee flexion gait, and synergistic neuro-excitability of the gastrocnemius was enhanced. Our early results suggest preservation of the gastrocnemius in treating knee flexion gait, especially for patients with knee flexion contracture.

Knee Flexion Contracture

Background Heel-height difference has been used to detect subtle knee flexion contractures, but the effects of thigh circumference differences and patient positioning during testing have not been evaluated. Hypothesis Differences in thigh circumference measurements and whether the patient's patellae are on or off the examination table during heel-height difference measurement will not affect the accuracy of detecting knee flexion contracture. Study Design Prospective cohort study. Methods Bilateral knee range of motion, prone heel-height difference with the patellae on and off the table, and thigh circumference at 5 and 15 cm proximal to the proximal pole of the patella were measured by one investigator on 50 consecutive patients who had undergone unilateral anterior cruciate ligament reconstruction. Results A high degree of correlation was demonstrated between the heel-height difference and the standard range of motion measurement. Differences in thigh girth and patellar position did not statistically affect the accuracy of the heel-height difference as an indicator of knee flexion contracture. Conclusion Heel-height difference is a valid method of documenting knee flexion contractures. Compared with traditional goniometer assessment, this test is a more meaningful and easier way for detecting subtle knee flexion contractures of less than 10°.
