what is patellar instability?
Patellar instability is a condition in which the patella (knee cap) becomes dislocated or unstable. This can happen as a result of trauma, such as a sports injury, or it can occur due to structural abnormalities in the knee joint, such as a shallow femoral groove or a high-riding patella.
Symptoms of patellar instability may include pain, swelling, and difficulty moving the knee. In some cases, the patella may pop out of place and then go back in on its own, while in other cases it may require manual reduction (putting it back into place).
Treatment for patellar instability may include physical therapy, bracing, or surgery to realign the patella and/or reconstruct the supporting structures of the knee. The specific treatment will depend on the underlying cause of the instability and the severity of the condition.
