Outcome measures
Primary outcome
Primary outcomes are recovery (7-point Likert scale), semi-quantative features
of the patellofemoral joint.
Secondary outcome
Pain, function, medical consumption, sport activity.
Background summary
The patellofemoral painsyndrome (PFPS) is the most common overload injury in a
relatively young and active population. A randomized trial (Pex-study)
investigating the effectiveness of supervised exercise therapy, showed that
exercise therapy is more effective compared to usual care in decreasing pain
and improving function, at both short and long-term follow-up. However, 40% of
the patients in the exercise therapy group indicated to have persistent
complaints after 12 months follow-up.
Study objective
To investigate the percentage of patients with persistent complaints and/or
radiological abnormalities after 5 years follow-up after the first visit to the
general practitioner or sport physician. 2. To investigate the long term
effectiveness of supervised exercise compared to usual care at long-term
follow-up. 3. To investigate possible prognostic factors associated with
persistent complaints after 5 years of follow-up.
Study design
The study concerns a long-term follow-up of 131 patients who participated in
the Pex-study. Data will be collected with a questionnaire, physical
examination and X-ray of the knee.
Study burden and risks
The risk to the subject will be minimal, because the research will exist of the
usual care, except filling out an questionnaire. Burden for the subject will
also be minimal, except X-ray radiation, and will be mainly exist of time for
filling out a questionnaire, under wending a physical examination and an X-ray.
There will be no direct benefits for the patients in this study.

Inclusion criteria
At baseline, patients with patellofemoral painsyndrome (the presence of at least three of the following symptoms: pain when walking up or down stairs; pain when squatting; pain when running; pain when cycling; pain when sitting with knees flexed for a prolonged period of time; grinding of the patella; and a positive clinical patellar test (such as Clarke*s test or patellar femoral grinding test)) were included. All patients that had participated in the randomised clinical trail will be included in the follow-up study. These patients will be 18 years and older at the 6-year follow-up study.
Exclusion criteria
At baseline, patients were excluded if they had knee osteoarthritis, patellar tendinopathy, Osgood-Schlatter disease, or other defined pathological conditions of the knee, or had previous knee injuries or surgery. Patients who have indicated in the past that they wish not longer to participate in the
study will be excluded in this 6 year follow-up study
