Tibia Lengthening: When is Gastrocnemius Recession necessary

Edit Post

For tibial lengthening, I read that gastrocnemius recession is necessary if the patient lengthens somewhere between 4.0cm to 4.5cm or more. Does that mean if tibial lengthening is done below a certain limit (such as under 3.6cm), gastrocnemius recession is not necessary?

In addition to Height Journey's reference (which I also found), here is another study by Dr Rozbruch.

Role and Outcome of Gastrocnemius Recession in Tibial Lengthening

Risk factors that led to need for GR were amount and percent of lengthening of 49 mm and 15% [of original tibia length] respectively, congenital etiology, and previous surgery.
