How is lateral patellar subluxation treated?

Nonsurgical treatment includes:

RICE (rest, icing, compression, and elevation)
nonsteroidal anti-inflammatory drugs (NSAID), such as ibuprofen (Advil, Motrin)
physical therapy.
crutches or a cane to take weight off the knee.
braces or casts to immobilize the knee.
specialized footwear to decrease pressure on the kneecap.

What is the difference between a patellar dislocation and subluxation?

In a patellar dislocation, the patella gets pushed completely out of the groove. The other type of instability is known as chronic patellar instability. In this type, the kneecap usually only slides partly out of the groove. This is known as a subluxation.

What are two mechanisms of injury for patellar subluxation or dislocation?

Acute patellar dislocations typically occur as a result of trauma, usually a non-contact twisting injury to the knee, or from a direct blow to the medial aspect of the knee. A common mechanism is external tibial rotation with the foot fixed on the ground.

What is medial patellar subluxation?

Medial patellar subluxation is a poorly recognized clinical condition characterized by chronic anterior knee pain that is exacerbated with knee flexion. Additional symptoms include instability, limited knee motion, and pain with squatting and stair climbing.

What causes lateral subluxation of the patella?

What Causes Patellar Subluxation? The most common cause is weakness and/or tightness of certain muscles in the hip and thigh, which can make the knee move differently than it should. A direct blow to the front or side of the knee that pushes the kneecap out of its groove.

What causes patella subluxation?

How long does patellar subluxation last?

It will take about 4 to 6 weeks or more for these tissues to heal. During this time, the knee must be protected to prevent another injury. Once a patella dislocation or subluxation has occurred, it’s more likely to happen again.

How is lateral release used to treat Patellar subluxation?

Lateral release Until about 10 years ago, lateral release was the standard surgical treatment for patellar subluxation, but it’s rare nowadays because it increases the risk of recurrence of instability in the kneecap. In this procedure, ligaments on the outside of the knee are partially cut to prevent them from pulling the kneecap to the side.

What causes instability in the patellar subluxation joint?

The bottom line is that several factors lead to instability of the kneecap. Possible factors include a wider pelvis, a shallow groove for the kneecap, and abnormalities in a person’s gait. There has been tremendous interest in recent years of the way our muscles help guide the kneecap as it bends in the knee joint.

Are there signs of Patellar subluxation in the retina?

There is also evidence of patellofemoral joint effusion along with thickening and increased signal intensity of the medial patellar retinaculum as well as medial patellofemoral ligament. The vastus medialis oblique muscles however appears to be intact and normal. Lateral patellar retinaculum also appears to have mild increased signal intensity.

What happens to the patella when the kneecap is dislocated?

When patellar dislocation occurs, soft tissues are damaged as the patella “jumps” the track and then comes forcibly back into place. Because the kneecap dislocates toward the outside of the leg, the ligament on the inside of the knee (the MPFL) gets torn. Left untreated, an injured MPFL can heal on its own.
