The kneecap is also called the patella. This page deals with loose kneecap problems and anterior knee pain. The joint between the kneecap and its guide groove (trochlea) is quite complicated. Unfortunately, many have undergone unsuccessful surgeries and been treated incorrectly. In recent years, understanding of the joint has improved. My interest and research has focused on understanding the joint better. This page is here to help you, so hopefully you can help yourself to a good treatment. 
Loose kneecap and/or anterior knee pain

Below is a menu where you can browse around and hopefully find something that suits you. Today, we know that there are a wide range of causes of kneecap problems. It’s crucial to find the exact reasons why you’re experiencing problems. Often the problem is that the knees are built crooked in one way or another. Before undergoing surgery, it is therefore important to find out if you are built crooked in one way or another. If you are built too crooked, surgery will often fail after a few months or years if the underlying cause is not addressed. 

Do I really need to get into this?

Unfortunately, patellar problems are not only complicated for you, but for your healthcare provider as well. In addition, new knowledge is constantly emerging. Your job is to learn a bit about it so you can ask critical questions to your therapist. Thankfully, there are skilled practitioners,  but don’t blindly trust them.  If in doubt, it’s a good idea to ask for a second opinion. This could be with a colleague or somewhere else entirely. I apologize for the messy site, but I hope you can still get something out of browsing around.

Loose kneecap and anterior knee pain are symptoms

There can be many and complicated reasons for having loose kneecap and anterior knee pain. It’s important to find all the causes. If surgery is required, correcting one thing is not enough. Anything that is highly skewed must be corrected, otherwise the result will not be good. Nothing is stronger than the weakest link. Some people think that just inserting a strong ligament to hold the kneecap is enough, but while it may hold the kneecap, it will cause poor function and pain. Below is an example of a 21-year-old woman from Norway who needed surgery on both legs due to both loose kneecaps and anterior knee pain. Each knee had to undergo 4 different types of surgeries in each knee, but on the other hand, it also turned out really well.

Combined surgery for loose kneecap and anterior knee pain

Combined but simultaneous surgeries in each knee

The above image is an example of complicated and advanced surgery. Thankfully, it is rare that so much needs to be corrected as in this case, where four things needed to be corrected:

  • 1. arthroscopic trochleoplasty due to severe trochlear dysplasia, 
  • 2. Patellar tendon lift surgery due to a too high kneecap
  • 3. De-rotation osteotomy due to too much rotation in the femur
  • 4. MPFL reconstruction to stabilize the kneecap.
