A 7‑year‑old male presents to the urgent‑care clinic with left‑knee pain that began after gym class and has gradually worsened over the past several weeks. The mother reports no significant trauma and notes that the pain improves with rest. Physical examination reveals a slightly overweight child with a visible bowing deformity just distal to the knee. The patient demonstrates a full range of motion and normal knee strength, and no bony tenderness, effusion, or laxity is noted. An anteroposterior (AP) radiograph of the left knee is ordered to further evaluate the deformity.
