Brief Summary

Self-reported, unspecific knee pain is highly prevalent among adolescents. A large proportion of the unspecific knee pain can be attributed to Patellofemoral Pain Syndrome (PFPS). There are a number of treatment options for PFPS. Physical therapy has been advocated as one of the cornerstones in rehabilitation of patients with PFPS. Twenty-five years ago, McConnell proposed a multimodal approach that combined several treatment options. The regimen included retraining of the vastus medialis oblique muscle through functional weight bearing activities. This exercise is combined with patellar taping, patellar mobilization, and stretching to improve patellar tracking, reduce pain, and enhance vastus medialis oblique muscle activation. Short term results (\<12 months) indicates that multimodal physiotherapy is more effective than placebo treatment. While treatment for PFPS may be successful for the short-term, long-term results are less promising. A recent review covering the long term prognosis for patients diagnosed with PFPS, reported that only 1/3 of those diagnosed with PFPS and treated conservatively were pain free 12 months after diagnosis. Further ¼ stopped participating in sports because of knee pain. Predictors of long term outcome (\>52weeks) indicate that a long symptom duration, higher age and greater severity at baseline are associated to poorer outcome after treatment. These prognostic factors suggest that an early initiation of treatment might lead to a better long-term prognosis. The purpose of this study is to examine the short and long-term effectiveness of multi-modal physiotherapy compared to standard wait-and-see treatment applied at a very early state of disease among adolescents. The investigators hypothesized a significantly larger proportion of completely recovered patients at three-month follow-up in the interventions group compared to the control group.

Study Arms (3)

Information and patient education

ACTIVE COMPARATOR

All subjects will receive one-to-one patient education delivered by a physiotherapist. The information will be standardized and cover the topics of: why does it hurt: pain management; information of how to reduce physical activity if necessary; how to return slowly to sports; how to cope with knee pain and information of how to increase knee alignment during walking and stair walking. The patients will also receive this information in written form. This information is expected to take approximately 45minutes per patient.

Behavioral: Patient information and education

The information will be standardized and cover the topics of: why does it hurt: pain management; information of how to reduce physical activity if necessary; how to return slowly to sports; how to cope with knee pain and information of how to increase knee alignment during walking and stair walking. In addition the patients will receive supervised multimodal physiotherapy carried out by a physiotherapist with previous experience in treating adolescents and PFPS and has more than two years of practical experience in these areas.

Other: Information, education and physiotherapy

Observational cohort

NO INTERVENTION

Those who do not wish to participate in the randomization procedure will be followed through an observational cohort. The observational cohort will be followed at the same time-points and they will be asked which treatment they have received.
