What is the femoral trochlea?
The trochlea of femur (femoral trochlea) is the cranial cartilaginous part of distal femur, for articulation with the patella fo form the femoral patellar joint. It consists of a groove bounded by the medial and a lateral ridges.
Where is the femoral trochlea located?
The normal trochlea is located in the anterior aspect of the distal femur. It is composed of two facets divided by a longitudinal groove, the trochlear sulcus. The lateral facet is the biggest; it extends more proximally than the medial facet and is more protuberant in the anteroposterior aspect.
What compartment is the femoral trochlea?
The patellofemoral compartment is composed of the suprapatellar pouch, the patella bone, its femoral articulation (called the trochlea), the medial and lateral femoral condyles, and the medial and lateral patellofemoral ligaments.
Is trochlear dysplasia serious?
Severe cases of trochlear dysplasia are rare, whereas more mild cases where the trochlear groove may be flatter than normal, are not that uncommon. Therefore, it is a relatively common condition, but often does not cause significant problems when it is a milder case of trochlear dysplasia.
Is the trochlea a bone?
In the human arm, the humeral trochlea is the medial portion of the articular surface of the elbow joint which articulates with the trochlear notch on the ulna in the forearm.

What is trochlea in knee?
The trochlea is a groove in the femur bone underneath the kneecap (patella). The walls of the trochlea stabilize the patella and allow it to glide down the center of the trochlea as the knee bends.
What is severe patellofemoral osteoarthritis?
Patellofemoral arthritis occurs when the articular cartilage along the trochlear groove and on the underside of the patella wears down and becomes inflamed. When cartilage wears away, it becomes frayed and, when the wear is severe, the underlying bone may become exposed.
Does trochlear dysplasia require surgery?
One form of treatment for patellofemoral instability in patients with severe trochlear dysplasia is a surgical procedure called trochleoplasty, in which the trochlear groove is reshaped to improve patellar stability.
Is trochlear dysplasia painful?
Trochlear dysplasia also causes knee pain during activities that involve bending the knee such as walking up or down the stairs or running. In the long term, the abnormal movement of the patella on the femur can lead to the development of wear and tear of your joint surface known as osteoarthritis.
What bone has a trochlea?
In the human arm, the humeral trochlea is the medial portion of the articular surface of the elbow joint which articulates with the trochlear notch on the ulna in the forearm.
What is the trochlea made of?
The outer layer is composed mostly of collagen and contains nerve fibres that cause pain when the tissue is damaged. It also contains many blood vessels, branches of which penetrate the bone to supply the osteocytes, or bone cells.
What happens if patellofemoral goes untreated?
If left untreated, PFPS may cause weakness of your knee. You may have pain with running, cycling, or walking up or down stairs or ramps. The chances of treating PFPS are better when causes are found and treated as soon as possible.
How do you fix patellofemoral arthritis?
Surgical Treatment
- Chondroplasty. This procedure is done with arthroscopy — inserting thin surgical instruments into small incisions around your knee.
- Realignment.
- Cartilage grafting.
- Tibial tuberosity transfer.
- Patellofemoral replacement.
- Total knee replacement.
What is the treatment for trochlear dysplasia?
Trochleoplasty is indicated mainly for high-grade trochlear dysplasia. In the majority of these cases, trochleoplasty is performed in association with other procedures (such as anterior tibial tubercle [ATT] transfer or medial patella-femoral ligament [MPFL] reconstruction).
Is trochlear dysplasia a disease?
TD is not a disease and most individuals who have this abnormality, are asymptomatic and as such, TD is a condition. The higher the degree of TD, the higher the risk of becoming symptomatic is, either by patellofemoral instability (PFI), patellofemoral pain (PFP) or patellofemoral osteoarthritis (PF OA).
What is trochlea of knee?
Is the trochlea and condyle?
Trochlea of humerus – Trochlea humeri
The condyle of humerus is the whole distal end except the epicondyles. The condyle articulates with the radius and ulna forming the elbow joint. In dog and cats, the condyle is divided in two parts: The trochlea, the medial part, that articulates with ulna.
What is the function of the Trochlear?
The trochlear nerve is one of 12 sets of cranial nerves. It enables movement in the eye’s superior oblique muscle. This makes it possible to look down. The nerve also enables you to move your eyes toward your nose or away from it.
Is walking good for patellofemoral syndrome?
Proper walking or running shoes can help knee pain. Even a simple arch support insert from a shoe store can be helpful. This insert is much less expensive than a custom-made orthotic. Ice your knees for 10 to 20 minutes after activity.
Do you need surgery for patellofemoral syndrome?
Treatment of patellofemoral pain syndrome usually includes avoiding any activity, sport or exercise that makes the knee pain worse, anti-inflammatory medications and sometimes wearing soft braces. Surgery is rarely required.
Is walking good for patellofemoral arthritis?
Patients who have patellofemoral arthritis should try to avoid activities that put stress on the front of the knee, such as squatting. If you regularly do high-impact exercise, switching to low-impact activities will put less stress on your knee. Walking and swimming are good low-impact options.
How painful is patellofemoral arthritis?
Patellofemoral joint (PFJ) pain cause pain at the front of the knee. The pain is often hard to pinpoint and feels deep in the joint or ‘behind the knee cap’. It is more common in females then males and is often aggravated by prolonged walking particularly downstairs and/or down hill’s, squatting, lunging and running.
How do you fix trochlear dysplasia?
Trochleoplasty is a surgical procedure to treat a condition called trochlear dysplasia, where the trochlear groove is abnormally shaped, causing the patella (kneecap) to slip out of the groove or dislocate.
What is a trochlea in medical terms?
Medical Definition of trochlea
: an anatomical structure resembling a pulley: as. a : the articular surface on the medial condyle of the humerus that articulates with the ulna. b : the fibrous ring in the inner upper part of the orbit through which the tendon of the superior oblique muscle of the eye passes.
What bone is the trochlea on?
the humerus
In the human body, many pulley-like structures are known as a trochlea; for example, the medial part of an articular area at the lower end of the humerus is called the trochlea. A ligamentous structure attached to the hyoid bone acts as pully for the digastric muscle.
