Show Solution
The Correct Option is B
Solution and Explanation
Blount's disease, known in orthopedics as tibia vara, is a pathological deformity arising at the medial aspect of the proximal tibial growth plate. Excessive compressive force, frequently linked with childhood obesity and walking at an unusually early age, suppresses normal growth of the inner (medial) tibial physis while the lateral side keeps growing. The result is that the tibia tilts and the leg deviates toward the body's midline. A deformity where the leg bows outward at the knee, bringing the ankles apart while the knees stay together, is by definition genu varum (bow-leg). Therefore Blount's disease manifests clinically as genu varum. The distractors can be excluded on simple definitions: genu valgum is the opposite knock-knee posture, genu recurvatum denotes backward over-extension of the knee at the tibiofemoral joint, and meniscal injury is an intra-articular cartilage tear unrelated to physeal growth. A key point is that Blount's deformity is progressive and worsens with age, unlike benign physiological bowing that self-corrects. $\text{Tibia vara} = \text{genu varum}$.
