A Clinical Study in the Use of Orthotics in Treating Pain in the Front of the Knee.

This study is testing whether shoe inserts (orthotics) can help relieve pain at the front of the knee, a common condition called patellofemoral pain syndrome (PFPS). This type of knee pain is not caused by an injury — it happens when the kneecap doesn't track smoothly in its groove, causing aching during activities like climbing stairs, squatting, or sitting for a long time. Researchers want to find out if specially fitted orthotics reduce this pain. You may be eligible if: - You have been diagnosed with patellofemoral pain syndrome (kneecap pain not caused by injury) - Your knee pain has been present for at least 6 weeks - You have pain with at least 2 of the following: stair walking, jogging or running, squatting, hopping or jumping, kneeling, or sitting for long periods You may NOT be eligible if: - You have injury or damage to other parts of your knee (such as the meniscus or ligaments) - You have pain in your lower back or hip that travels to your knee - You have had a knee fracture or your kneecap has dislocated - You have had physiotherapy or patellar taping in the past 12 months - You are allergic to adhesive tape - You currently use or have previously used foot orthotics - You have any foot condition that prevents you from wearing orthotics Talk to your doctor about whether this trial might be right for you.
