Does patellar dislocation require surgery?

Conservative treatment is typically used if it’s the first time you have dislocated your kneecap. If it happens a second time or if it keeps happening, surgery is usually considered.

How does a patellar dislocation occur?

Causes. Patellar dislocations can occur either in contact or non-contact situations. An athlete can dislocate his/her patella when the foot is planted and a rapid change of direction or twisting occurs. Usually a pre-existence ligamentous laxity is required to allow a dislocation to occur in this manner.

What happens when your patella dislocates?

When the patella dislocates, it’s forced outside of the trochlear groove and can no longer move up and down. This locks the knee and pulls the ligaments out of place, often tearing them. Most frequently (93% of the time), the kneecap pops out laterally, to the side of the groove.

How is patella dislocation treated?

Early treatment includes:

  1. Physical Therapy with an emphasis on strengthening the quadriceps (the muscles of the thigh)
  2. Bracing and taping – Special knee braces are designed to control how the kneecap moves.
  3. Surgery – Some patients may need surgery, especially if they have a lot of pain or repeated dislocations.

Is patellar dislocation serious?

A dislocated kneecap is not usually serious and will often pop back into place by itself. But it’s still a good idea to get it checked by a health professional: if your kneecap has gone back into place by itself – go to your nearest urgent treatment centre or A&E.

How long is recovery for dislocated patella?

It usually takes about six weeks to fully recover from a dislocated patella, although sometimes it can take longer to return to sports or other strenuous activities.

Can you walk with a dislocated patella?

Kneecap subluxation or dislocation may occur more than once. The first few times it happens will be painful, and you will be unable to walk. If subluxations continue to occur and are not treated, you may feel less pain when they happen. However, there may be more damage to your knee joint each time it happens.
