Trial 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. Read more about this study

About this study

Official title: Early Intervention for Adolescents With Patellofemoral Pain Syndrome - a Cluster Randomized Trial

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Patient information and educationBehavioural

    Also called Standard care

    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.

  • Information, education and physiotherapyOther

    Also called Physiotherapy, Multimodal intervention

    Patients 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.

    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. The multimodal physiotherapy intervention will be carried out at school premises right after the end of class.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in perception of recovery after 12 months measured on a 7-point likert scale ranging from "completely recovered" to "worse than ever".

    Perception of recovery after 12 months measured on a 7-point likert scale ranging from "completely recovered" to "worse than ever".

    Measured: Baseline, 3, 6, 12 and 24months

Secondary outcomes (3)
  1. Knee Injury and Osteoarthritis Outcome Score

    Measured: Baseline, 3, 6, 12 and 24months

  2. EQ5D

    Measured: Baseline, 3, 6, 12 and 24months

  3. Neuromuscular function

    Each subjects will undergo quadriceps strength measurements and two basic tests of neuromuscular function of m. vastus medialis and m. vastus lateralis. EMG will be collected during two different conditions: Walking and semi-squat at 90 degrees flexion at the knee joint.

    Measured: Baseline and 3 months
