Torsional Deformity Masquerading as Knee Instability

Persistent knee pain and gait disturbance exposed an overlooked lower extremity diagnosis.

Share

A 15-year-old girl presented with chronic anterior knee pain and gait dysfunction for two years, despite normal imaging results. Symptoms included a right-sided pain, varus-hyperextension gait, and clunking sounds. Conservative treatments failed, leading to advanced imaging, revealing significant lower extremity torsional abnormalities. The patient underwent surgical correction via femoral and tibial osteotomies, resulting in pain resolution and improved gait mechanics over two years. This case highlights the underrecognized issue of lower extremity torsional abnormalities as a cause of knee pain in adolescents with normal imaging.
