Partial epiphysiodesis at the knee to correct angular deformity.

A method of partial epiphysiodesis is described for correction of idiopathic genu valgum or varum in the adolescent patient. A standard curve is used to determine the proper timing for partial epiphysiodesis, including allowance for the remaining growth to correct the deformity before skeletal maturity is reached. The surgical technique is designed to produce partial epiphysiodesis of the femur and/or tibia. The advantages of this procedure are predictability, a small scar, and the avoidance of a second procedure. The results in 13 extremities treated and followed to maturity demonstrate the efficacy of the operation.
