Patella Alta & Baja - What is the Difference?

What are symptoms of patella alta?

There are a variety of symptoms that point to patella alta. Instability in your step is a good indicator of a higher kneecap. For example, if you feel unstable while walking or running you may have patella alta. Pain experienced in the kneecap may hint to issues with the location of your patella. However, there are many other patellar conditions in which you may experience a similar sensation and location of pain. The most prominent indication of patella alta is dislocation of the kneecap. The patella can bend higher than normal which can pull the knee out of its groove causing a dislocation. If you have a misaligned patella it can create additional patellar issues because it causes the cartilage to wear down. This condition is widely known as chondromalacia.

What are symptoms of patella baja?

When a person has patella baja their range of motion is likely much more limited than normal. They may also experience scarring and shortening of the patella baja posterior, meaning back of the knee. Pain from patella baja is most often experienced on the anterior, meaning front and center of your knee. If you’re noticing that it takes you a more than normal level of energy to make movements, patella baja may be a potential cause.

Patella alta can be treated in a variety of different ways with the goal being restoration of strength and stability for the kneecap. This restoration will help to relieve symptoms of patella alta. Sufficient rest and time off the kneecap will allow for reduced stress, this is especially important for people who began experiencing patella alta after an injury or dislocation. Inflammation and pain can be lessened by the regular application of ice to the kneecap area. Wearing a brace that increases support and compression on the upper portion of the knee will help to stabilize and reduce pain. When looking for a support brace or wrap for patella alta, make sure to find a c or u-shaped buttress that is either adjustable or placed on the top of the kneecap.
