Genu Varum and Genu Valgum Correction: Modern Surgical Realignment by Prof. Ahmed Elsheikh

Genu Varum and Genu Valgum: Understanding Leg Bowing Deformities

Genu Varum (outward leg bowing) and Genu Valgum (inward knock knees) are common structural angular deformities affecting lower limb alignment. Left untreated in adolescents and adults, these deformities alter mechanical weight-bearing forces across the knee joint, concentrating excessive pressure on a single compartment and accelerating premature knee cartilage wear (osteoarthritis).

Biomechanical Consequences of Leg Angular Deformity

Prof. Ahmed Elsheikh emphasizes that normal gait mechanics require the weight-bearing line (mechanical axis) to pass directly through the center of the knee joint. In Genu Varum, the axis shifts medially, leading to inner knee compartment overload and cartilage degeneration. In Genu Valgum, the axis shifts laterally, overloading the outer compartment and patellofemoral tracking.

Clinical Indications for Surgical Osteotomy

Prof. Ahmed Elsheikh highlights key indications where surgical realignment is mandated:

• Progressive outward or inward bowing of the tibia (shin) or femur (thigh).
• Persistent knee joint pain during daily walking or sports activities.
• Asymmetry in leg shape impacting physical appearance and confidence.
• Early radiological signs of compartmental joint space narrowing.

High Tibial Osteotomy (HTO) vs. Hexapod Frame Realignment

Treatment strategy depends on patient age, deformity magnitude, and joint status. For focal angular deformities near the knee joint, a High Tibial Osteotomy (HTO) or Distal Femoral Osteotomy (DFO) realigns the mechanical axis with millimeter precision, securing bone with rigid internal locking plates.

For multi-planar complex deformities involving rotation or shortness, computer-guided hexapod frames (such as the Taylor Spatial Frame or Ortho-SUV Frame) allow gradual post-operative adjustment in 3D space.

Correcting mechanical alignment before cartilage destruction preserves natural knee joint longevity, postponing or eliminating the need for joint replacement.

Rehabilitation & Post-Operative Recovery

Rehabilitation begins immediately post-surgery. Patients follow a tailored physical therapy program focusing on knee range of motion, quadriceps strengthening, and gradual weight-bearing progression under specialist supervision.
