Efficacy and Safety of Percutaneous Epiphysiodesis Operation around the Knee to Reduce Adult Height in Extremely Tall Adolescent Girls and Boys

Objective. The aim was to determine efficacy and safety of a surgical method to reduce adult height in extremely tall adolescents. Methods. Data for all girls () and boys () in our center subjected to bilateral percutaneous epiphysiodesis around the knee who had reached final height were included. Final height predictions were based on hand and wrist X-rays before surgery. Results. When compared to prediction, adult height was reduced by cm in treated girls () and cm in treated boys () corresponding to a % and % reduction of remaining growth, respectively. Besides mild to moderate postoperative pain reported in 9 operated individuals, no other side effects were reported. Postoperative X-rays confirmed growth plate closure and absence of leg angulations. Conclusions. Bilateral epiphysiodesis is an effective and safe method to reduce adult height in extremely tall girls and boys.
