The relationships between patellofemoral bone remodeling, cartilage composition, and vertical loading rate: PET/MRI in isolated patellofemoral osteoarthritis
Authors' conclusion
Evidence of simultaneous, complementary, cross-sectional associations between T1p-T2 values and peak vertical loading rates with 18NaF-SUV, have been rare in the isolated PFJ-OA cohort.
Study context
- Population
- Patients with isolated patellofemoral-joint OA, with no tibiofemoral involvement
- Participants
- 35 patients
- Outcome
- Associations between subregional 18NaF-SUV, cartilage T1p-T2 values and vertical ground reaction force loading rates
Methodological detailsPET/MRI (simultaneous 3.0T hybrid scanner), linear mixed-effects modeling
- PET/MRI (simultaneous 3.0T hybrid scanner)
- Linear mixed-effects modeling
Main finding
As reported in the abstract
- Significant, complex associations between medial and lateral bone 18NaF-SUV uptakes and medial and lateral cartilage subregional T1p and T2
- SUVMean and SUVMax positively associated with deep cartilage subregional T1p and T2 values, and negatively with superficial cartilage subregional T1p-T2 values, in both medial and lateral regions
- Medial and lateral bone 18NaF-SUVMean and SUVMax uptakes positively associated with peak vertical impact loading rates (Loading-RateNorm)
Observational data: associations, not effects.
