Definition[edit | edit source]
Valgus knee or knock knee is a lower leg deformity that exists when the bone at the knee joint is angled out and away from the body's midline. This deformity is defined as a valgus angle equal to or greater than 10°[1]
The valgus deformity is resulted of anatomical variations : bone tissue remodelling and soft tissue contraction/elongation.
Bone tissue remodelling:
- Lateral femoral condyle deficiency with external rotation deformity of the tibia and lateral tibial plateau deficiency as well.
- The patellofemoral joint can be affected with lateral subluxation of the patella and trochlear blunting secondary to lateral femoral condylar wear.
Soft tissue contraction/elongation:
- The lateral side is contracted including the lateral collateral ligament (LCL), popliteus tendon, posterolateral capsule, iliotibial band (IT band), and posterior capsule.
- The medial side, the soft tissue are attenuated, the medial collateral ligament (MCL) .
