Knee Deformity Clinical Trial
Official title:
Correction of Fixed Knee Flexion Deformity in Children Using Eight-plate Hemiepiphysiodesis
The study aims to assess the effectiveness of hemiephysiodesis using eight plates in correction of fixed knee flexion deformities in children.
Flexion contractures of the knee are quite disabling. They produce deleterious effects on knee biomechanics, quadriceps function, energy expenditure during gait and the overall ability to ambulate. These deformities occur secondary to a number of different etiologies including; congenital, traumatic, inflammatory and neuromuscular disorders with cerebral palsy (CP) being on the top of the list. The main aim of correction of sagittal plane deformities of the knee is to restore the range of motion. Surgical options available for correction of knee flexion contractures include soft tissue modification, acute correction by osteotomies, gradual correction by external fixators and growth modulation by hemiephysiodesis.Extensive soft tissue surgery may be needed for correction of knee deformities with potential risk of neurovascular damage and wound complications. Supracondylar extension osteotomies have been widely used, however prolonged immobilization and associated neurovascular insults have always been major concerns. External fixators are cumbersome and may produce muscle tethering and pin tract infections. There are few studies in the literature reporting the use of anterior hemiepiphysiodesis for correction of knee flexion contracture. Our study question can be summarized as follows; Is hemiepiphysiodesis by eight plates effective for correction of fixed knee flexion deformities in children ? ;
