PURPOSE: To conduct a systematic review of psychometric properties of
self-reported questionnaires used to assess the level of symptoms and disability
in individuals with patellofemoral pain syndrome (PFPS). METHODS: A structured
search was conducted in four databases (Medline, Embase, CINAHL, SportDiscus). A
total of 24 studies about five different self-reported questionnaires were
analyzed. A pair of independent raters extracted data on validity, reliability
and responsiveness to change, and performed critical appraisal (0-100%). RESULTS:
Activities of Daily Living Scale (ADLS), Anterior Knee Pain Scale (AKPS),
International Knee Documentation Committee (IKDC) and Lysholm Scale (LS) present
excellent test-retest reliability (weighted average intraclass correlation
coefficients [ICC] > 0.80), whereas Functional Index Questionnaire (FIQ) is
moderately reliable (ICC = 0.61). Minimal detectable change is 8.3% for ADLS,
9.0% for AKPS, 19% for FIQ, 8.5% for IKDC and 30% for LS. ADLS, AKPS, IKDC and LS
are highly responsive (effect size/standardized response mean >0.95) in
individuals with PFPS, while FIQ is lowly responsive (effect size = 0.49).
CONCLUSION: Based on available evidence, ADLS presents the best psychometric
properties and should be preferred when evaluating patients with PFPS. AKPS and
IKDC are also adequate, while FIQ and LS are not recommended for individuals with
PFPS. IMPLICATIONS FOR REHABILITATION: While several questionnaires have been
developed to assess symptoms and functional limitations caused by knee pain,
their psychometric properties can vary depending on the condition presented by
the patient. The Activities of Daily Living Scale of the Knee Outcome Survey
should be preferred by clinicians when evaluating a patient with PFPS. The Anterior Knee Pain Scale and International Knee Documentation Committee
Subjective knee evaluation are also adequate for use with this population. The
Functional Index Questionnaire and Lysholm Scale are not recommended for PFPS.
