Abstract

Case:

A 16-year-old boy with habitual patellar dislocation during knee extension accompanied by bilateral severe trochlear dysplasia and excessive lateral deviation of the tibial tubercle underwent medial patellofemoral ligament reconstruction with switching wedged tibial tubercle transfer osteotomy. This technique involves making 2 wedge-shaped osteotomies on the tibial tuberosity and its medial side in the axial plane and subsequently inverting the 2 bone fragments to move the tibial tuberosity medially.

Conclusion:

Switching wedged tibial tubercle transfer osteotomy combined with medial patellofemoral ligament reconstruction can help enable substantial correction in cases of severe tibial tubercle lateralization.

Bones of the Lower Limb: Femur and Patella

The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...
