  2. Intercondylar fossa of femur - Wikipedia

    en.wikipedia.org/wiki/Intercondylar_fossa_of_femur

    The intercondylar fossa of femur and/or the patellar surface may also be referred to as the patellar groove, patellar sulcus, patellofemoral groove, femoropatellar groove, femoral groove, femoral sulcus, trochlear groove of femur, trochlear sulcus of femur, trochlear surface of femur, or trochlea of femur.

  3. Luxating patella - Wikipedia

    en.wikipedia.org/wiki/Luxating_patella

    Grade IV - the patella is permanently luxated and cannot be manually repositioned, with up to 90° of rotation of the proximal tibial plateau. The femoral trochlear groove is shallow or absent, with displacement of the quadriceps muscle group in the direction of luxation.

  4. Patellar dislocation - Wikipedia

    en.wikipedia.org/wiki/Patellar_dislocation

    When there is too much tension on the patella, the ligaments will be susceptible to tearing due to shear force or torsion force, which then displaces the patella from its groove. [3] Patellar dislocation may also occur when the trochlear groove is shallow, a condition defined as trochlear dysplasia .

  5. Medial patellofemoral ligament - Wikipedia

    en.wikipedia.org/wiki/Medial_patellofemoral_ligament

    The patella rests in the trochlear, which is found in the distal part of the femur. The patella can dislocate from the groove because of trauma or an unnatural twisting of the knee. [5] When dislocated, the soft tissue layer that the patella rests in is damaged; the patella is forced out of its groove and back into place.

  6. Lower extremity of femur - Wikipedia

    en.wikipedia.org/wiki/Lower_extremity_of_femur

    The lower extremity of femur (or distal extremity) is the lower end of the femur (thigh bone) in human and other animals, closer to the knee. It is larger than the upper extremity of femur, is somewhat cuboid in form, but its transverse diameter is greater than its antero-posterior; it consists of two oblong eminences known as the lateral condyle and medial condyle.

  7. Patellar subluxation syndrome - Wikipedia

    en.wikipedia.org/wiki/Patellar_subluxation_syndrome

    Patellar subluxation can be caused by osseous abnormalities, such as incorrect articulation of the femoral groove with the patella, trochlear dysplasia, or patella alta, which is a distance of greater than 20 mm between the tibial tubercle and the trochlear groove.

  8. Capitulum of the humerus - Wikipedia

    en.wikipedia.org/wiki/Capitulum_of_the_humerus

    In non-avian archosaurs, including crocodiles, the capitellum and the trochlea are no longer bordered by distinct etc.- and entepicondyles respectively, and the distal humerus consists two gently expanded condyles, one lateral and one medial, separated by a shallow groove and a supinator process. Romer (1976) homologizes the capitellum in ...

  9. Trochlea of humerus - Wikipedia

    en.wikipedia.org/wiki/Trochlea_of_humerus

    The spiralling nature of the trochlear groove results in the varying transverse axes of the elbow joint. [3] Most frequently, the groove is vertical on the anterior side but runs down laterally on the posterior side. During elbow flexion, the vertical anterior part of the trochlea keeps the upper arm and forearm aligned (when viewed in front).
