Plate vs. Screw for Guided Growth in Coronal Knee Deformities
Condition(s) studied
Investigational drug(s) / intervention(s)
Tension Band Plate (TBP) Surgery: A guided growth procedure in which a non-locking 8-plate is placed extraperiosteally across the physis (growth plate) with two screws, one in the epiphysis and one in the metaphysis. This allows for gradual correction of coronal angular deformities without causing permanent growth arrest.
Percutaneous Epiphysiodesis by Transphyseal Screw (PETS) Surgery: A minimally invasive procedure in which a partially threaded cannulated screw is inserted across the growth plate (transphyseal) to slow growth on one side of the bone. This technique allows for gradual correction of genu valgum and genu varum.
Study summary
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.
Eligibility
Primary outcome measure(s)
- Bone-Length Adjusted Angular Correction Rate (BLAACR) — Measured at 3-month intervals until clinical correction is achieved, up to 12 months
The Bone-Length Adjusted Angular Correction Rate (BLAACR) measures the effectiveness of guided growth correction by normalizing the angular correction rate based on limb growth. This method reduces bias in comparing the Tension Band Plate (TBP) and Percutaneous Epiphysiodesis by Transphyseal Screw (PETS) by accounting for variations in growth rate among participants. The formula is: BLAACR = (Change in Angular Deformity) / (Increase in Bone Length), where: -- Change in Angular Deformity = Initial Angle - Final Angle * Increase in Bone Length = Initial Bone Length - Final Bone Length
