Inclusion criteria

Inclusion criteria: Patients suffering from a patellofemoral pain syndrome (PFSS) for longer than 2 month but not longer than 2 years can be included in this study. The diagnosis PFSS is confirmed if three of the following symptoms are present for this time: - Anterior knee pain while running - Anterior knee pain while climbing stairs - Anterior knee pain while bicycling - Anterior knee pain while sitting with flexed knees - Anterior knee pain while squatting

Exclusion criteria

Exclusion criteria: Osteoarthritis 3° to 4° - Local cartilage damage 3° to 4° - Subluxation of the patella - Previous knee injuries (ACL ruptures) - tendinosis of the patella tendon - M. Osgood Schlatter - Pathological damage of the knee joint (Osteochondrosis dissecans) - Valgus knee with more than three fingers between teh malleoli - Varus knee with more than 2 fingers between the femoral condyles

Design outcomes

Primary

Measure	Time frame
The primary outcomes of this study are: 1. the healing score (7 points Lickert scale), 2. the functional Patella Score (Kujala Score), 3. the Knee Pain and Osteoarthritis Outcome Score (KOOS), and 4. the severity of pain at serveral activities measured on a nummerical analog scale (0-100). Ad 1: The healing score (7 points Lickert scale), The success with regard to healing is assessed with use of a 7 points Lickert scale: 1Complete healing 2Nearly healed 3Significantly improved 4moderate improvement 5little improvement 6slight gebessert 7 As bad as ever Patient are classified as healed if they are in category one and two. This procedure was published by Van Linschoten et al. (2009) for a study evaluating the effect of physiotherapy on the PFPS . Ad 2: The functional results should be evaluatetd with the Kujala Score (Kujala Patellofemoral Scala). This score is a special patella score with 13 categories: 1. Limping ,2. weigth bearing, 3. walking, 4. clinmbing stairs, 5. squatting, 6. running, 7. jumping, 8. sitting with bended knees, 9. pain, 10. swelling, 11. subluxations, 12. thigh atrophy, 13. restriction of flexion. Ad. The KOOS was validated by Roos et al. (1998). The KOOS was developed to examine patients with knee problems. This score can be used for short and long term follow up and it has 5 subscales: Pain, other syymptoms, function at daily living, function at sport and quality of living. The KOOS has standardized answering options (Lickert Skala). An overall score is calculated from the different subscales (0: extremely sever symptoms, 100: no symptoms). The KOOS iss elf explaining and ideal for self assessement of the patients. Ad. 4: Pain on a nummerical scale (0: no pain to 100: servere pain) Activities a)Walking, b)at rest, c)climbing stairs d)sitting with flexed knee e)sport. All scores are evaluated at the initial visit, after 6 weeks, after 3 month and after 12 month.	—
