Abstract

Background

The aim of this study was to compare knee ultrasonography findings in patients with Patellofemoral Pain (PFP) and healthy controls.

Methods

Our cross-sectional study included 54 participants, 27 patients with PFP and 27 healthy controls. Medial and lateral retinaculum thickness, trochlear cartilage thickness and patellofemoral distances were measured by ultrasonography In the PFP group, pain intensity at rest and during activity was assessed by Visual Analogue Scale (VAS, 0–10 cm), functional status was assessed by Kujala Patellofemoral Pain Scoring system. The quality of life of both groups was evaluated with the Short Form-36 (SF-36).

Results

The groups were similar in terms of age, gender, body mass index (BMI), marital status, educational level and dominant extremity. In the PFP group, medial and lateral retinaculum thickness, medial patellofemoral distance were found to be significantly higher (mean difference [MD]:1.08; 95% confidence interval [CI]:0.87–1.28, MD:0.80; 95%CI:0.59–1.01, MD:5.65; 95%CI:4.68–6.61, respectively), while medial and lateral cartilage thickness were found to be significantly lower than the control group (MD:1.32; 95%CI:1.0–1.64, MD:-1.56; 95%CI:-1.86--1.26, respectively). There was no significant difference in lateral patellofemoral distance between the two groups (p = 0.752). No statistically significant correlation was found between ultrasonography measurements and age, BMI, pain duration, Kujala score, VAS scores at rest and during activity and SF-36 subgroup scores in the PFP group.

Conclusion

In our study, medial retinaculum thickness, lateral retinaculum thickness and medial patellofemoral distance were statistically significantly higher and medial and lateral trochlear cartilage thickness were lower in the PFP group compared to the control group.

期刊介绍： The Knee is an international journal publishing studies on the clinical treatment and fundamental biomechanical characteristics of this joint. The aim of the journal is to provide a vehicle relevant to surgeons, biomedical engineers, imaging specialists, materials scientists, rehabilitation personnel and all those with an interest in the knee. The topics covered include, but are not limited to: • Anatomy, physiology, morphology and biochemistry; • Biomechanical studies; • Advances in the development of prosthetic, orthotic and augmentation devices; • Imaging and diagnostic techniques; • Pathology; • Trauma; • Surgery; • Rehabilitation.
