trochlea

pl. trochleae [L.] a pulley-shaped part or structure; various bony or fibrous structures through or over which tendons pass or with which other structures articulate, e.g. femoral, humeral, radial.

femoral trochlea
the articular surface on the cranial aspect of the distal femur upon which the patella glides.
humeral trochlea
grooved articular surface at the distal end of the humerus; articulates with the radius and ulna.

Similar to the development of the adult hip, it is possible that a well-centered, reduced patella could stimulate the trochlea to develop anatomically.
17) In 1974, Richards Medical introduced the concept of resurfacing both the patella and trochlea.

This eliminated from consideration the most proximal cuts of the patella since the proximal patella is not in contact with the trochlea when the knee is slightly bent.
Using ultrasound, Nietosvaara showed that the depth of the trochlea and the patellofemoral articulation were developed at birth, and the geometry of this joint resembled its adult form.
These include patella alta, trochlea dysplasia, an increased quadriceps or Q angle with secondary soft tissue problems, a weakened or hypoplastic vastus medialis oblique quadriceps muscle with a contracted lateral retinaculum, and an absent redundant medial patellofemoral ligament or the latter alone.
The lateral trochlear facet, which is normally 1 cm higher than the medial, provides a buttress to lateral patellar subluxation and helps maintain the patella's centered position in the trochlea (Fig.
The portal passes through the ECRB and supinator and creates a view of the medial capsule, coronoid, and trochlea.
The preferred locations include the lateral edge of the intercondylar notch or the superomedial trochlea.
The proximal aspect of the ulna consists of the greater sigmoid notch, which articulates with the trochlea of the distal humerus.
