Lengthening Osteotomy with or Without Elevation of the Lateral Trochlear Facet

Patellofemoral Pain, Instability, and Arthritis

Abstract

The femoral trochlea is important for controlling the patellofemoral gliding mechanism [1, 2]. Normal articular shape of trochlea and patella allows for undisturbed patellar engagement and tracking. The normal cartilaginous surface of the trochlea consists of the lateral and medial facets of the femoral sulcus and is defined by different criteria in the proximal-distal, medio-lateral, and anteroposterior direction [3–7]. The normal trochlea deepens from proximal to distal [3, 5, 7]. In the proximal-distal direction, it is longest laterally and shortest on the medial side (Fig. 29.1). The deepened trochlear groove separates the lateral facet from the medial part. In the antero-posterior measurements, the most anterior aspect of the lateral condyle is normally higher than the medial condyle, and the deepest point is represented by the centre of the trochlear groove [4, 6].
