The goal of this clinical trial is to compare two surgical techniques, Tension Band Plate (TBP) and Percutaneous Epiphysiodesis by Transphyseal Screw (PETS), in children with coronal angular knee deformities.
The main questions it aims to answer are:
* Which technique provides better correction of coronal knee deformities? * Are there differences in complication rates or recovery times between TBP and PETS?
Participants will:
* Undergo either TBP or PETS surgery for knee deformity correction. * Attend follow-up visits for radiographic and clinical evaluations.
Researchers will compare TBP and PETS groups to see if one method leads to better deformity correction and fewer complications.
Children and adolescents beyond the age of physiological varus/valgus correction (i.e., typically ≥4 years for genu varum and ≥7 years for genu valgum) with Mechanical Axis Deviation (MAD) in lower limbs and abnormal joint orientation angles, in the coronal plane either femoral or tibial.
Open physis (growth plate) on radiographs and at least one year of growth remaining before age of skeletal maturity (typically ≤14 years in females, ≤16 years in males).
Sick Physis as in Blount's disease stages III-V or any partial or total physeal arrest caused by trauma, inflammation or neoplasia.
