Objective: The aim of this study was to compare ultrasonographically measured quadriceps and patellar tendon thicknesses between Patellofemoral Pain Syndrome (PFPS) patients and age- and gender- matched healthy controls.
Methods: Among patients who presented to physical therapy and rehabilitation outpatient clinic in
January-December 2016, 61 volunteers (28 men and 33 women; mean age: 30.79 6.55 years) who
were eligible considering the inclusion and exclusion criteria were enrolled. 30 were diagnosed with
PFPS, and the remaining were age- and gender-matched healthy volunteers. Mean age was 30.03 5.67 years in healthy subjects and 45.2% were of male gender. The patient group had mean age of 31.57 7.37 years and 46.7% of the patients were male. Q angles were measured at standing, supine and sitting
positions. Patellar and femoral tendon thicknesses and areas were measured ultrasonographically. Kujala
questionnaire were used to evaluate the functional status of the participants.
Results: No significant difference was detected between groups regarding profession, educational
background, and body mass indices (BMI) (p0.05). Q angle values were significantly higher in the
patient group when compared to controls at standing , supine and sitting positions.
Kujala score was significantly lower in the PFPS group when compared to controls. Patellar and quadriceps
vs. tendon thicknesses were significantly higher in the PFPS group when compared to controls. There was no significant difference between groups regarding patellar tendon areas. Patellar tendon thickness values of 0.35 cm were found to have 66.7% sensitivity and 67.7% specificity for PFPS diagnosis in the ROC curve analysis (area under curve: 0.771, 95% confidence interval Quadriceps tendon thickness values of 0.54 cm were found to have 80% sensitivity and 71% specificity for PFPS diagnosis in the ROC curve analysis (area under curve: 0.824, 95% confidence interval. In PFPS patients, quadriceps tendon thickness had significant positive correlation with age and BMI ; and significant negative correlation with Kujala score. In the multivariate regression
analysis, quadriceps tendon thickness was independently associated with the presence of PFPS (Exp (B): 3.089, 95% confidence interval.
Conclusion: Our study demonstrates that ultrasonographically measured patellar and quadriceps tendon thicknesses are significantly higher in subjects with PFPS and particularly, quadriceps tendon thickness may be used for the diagnosis.
