Functional Recovery After Cosmetic Bilateral Tibial Lengthening (2019)

What this study covers

Published in International Orthopaedics, this study by Park, Lee (Dong Hoon Lee, Yonsei University), and colleagues followed 125 healthy individuals who had undergone bilateral cosmetic tibial lengthening. Three different techniques were used across the group: lengthening and then nailing (LATN), lengthening over an intramedullary nail (LON), and the intramedullary skeletal kinetic distractor (ISKD). Recovery was measured using the Sports Activity Rating Scale and International Knee Documentation Committee forms.

Recovery timeline

By two years after surgery, patients had recovered nearly full function for everyday activities and light sports. However, 31.2% of patients (39 out of 125) still reported some limitation in moderate to strenuous sports activities.

What this means in plain terms

This is one of the largest studies specifically tracking functional recovery after cosmetic tibial lengthening. The good news is that the vast majority of patients return to normal daily life within two years. Walking, climbing stairs, and light exercise recover well. However, about one in three patients may continue to experience some limitation with high-intensity activities like running or competitive sports. This is important information for anyone who is physically active and considering tibial lengthening, as it sets realistic expectations for long-term functional outcomes.
