Anterior Knee Pain Scale (AKPS): Assessing Function
The AKPS is a self-report tool that tracks how knee pain affects daily tasks like walking and squatting. It helps clinicians monitor symptoms and measure recovery progress in patients.

Anterior Knee Pain Scale (AKPS)
Also known as the Kujala score, the Anterior Knee Pain Scale (AKPS) is a 13-item questionnaire assessing how knee issues affect daily movement. It tracks symptoms like limping or trouble with stairs and squatting. Scored out of 100, this tool helps clinicians monitor progress in treating patellofemoral pain.

What is Anterior Knee Pain Scale (AKPS)
The Anterior Knee Pain Scale (AKPS) is a trusted tool for checking patellofemoral pain. It helps clinicians track knee function and symptoms easily. Also called the Kujala Scale, this thirteen-item questionnaire looks at how knee trouble impacts daily life. It focuses on subjective symptoms and functional limits. Patients answer questions about activities like walking, running, jumping, and climbing stairs. It also asks about limping, swelling, and pain while sitting with bent knees. Scores range from zero to one hundred, where higher numbers mean better knee health. This self-report survey is quick to finish, usually taking under ten minutes. It is great for monitoring progress during rehab or after surgery. Clinicians use it to spot changes in condition over time. It gives a clear picture of recovery and helps guide treatment plans effectively for better outcomes.
The Anterior Knee Pain Scale can be scored using one main approach: a weighted summation of thirteen specific items. You will look at questions covering activities like limping, walking, stair climbing, and squatting. Since not all symptoms affect function equally, each answer carries a specific point value. Simply sum these weighted points to get a final score ranging from 0 to 100. A perfect 100 means no pain or disability, while lower numbers suggest greater difficulty. This total gives physios a clear picture of how patellofemoral pain impacts a patient's daily life and recovery.
