Difficulty putting pressure on the kneecap may occur when the kneecap isn’t moving correctly; this might be due to instability or damage to the cartilage behind the kneecap. Bursitis or tendinitis of the knee may also contribute to this problem.
One possible cause is patellar instability, where the kneecap does not stay in place as well as it should. This instability occurs when the muscles and ligaments around the knee do not support the kneecap properly, causing it to move out of its normal path. If the kneecap moves too much or in the wrong direction, pressing on it can hurt.
Another possibility is cartilage damage under the kneecap, a condition sometimes called chondromalacia patellae. In this condition, the smooth cartilage that cushions the kneecap becomes softened or worn. This can lead to pain, especially when weight or pressure is applied to the knee. Injury or long-term wear and tear may also lead to these issues, along with bursitis or tendinitis.
If the problem persists, it's important for a doctor to evaluate the knee to determine which condition might be involved and to suggest treatments such as physical therapy or other interventions to help improve stability and reduce pain.
