No difference in quantitative MRI in PFP cartilage composition between patients with PFP and healthy controls

(Van Der Heijden et al., 2015)

Aims: To investigate differences in patellofemoral cartilage composition between patients with PFP and healthy control sub- jects using quantitative MRI

Methods: Cross-sectional case-control study, PFP group symptom duration from 2 months to 2 years, 14 to 40 yo. 64 patients and 70 controls.

Results: No significant differences were found in relaxation times of patellar and femoral cartilage between patients and control subjects within the adolescent and adult sub-groups.

Limitations: Small number, some did not do all MRI tests. Diagnostic criteria incomplete. Differences in controls needed adjustment. Selected population.

In practice: Cartilage composition seems not to differ between patients with PFP and asymptomatic controls.
