Prevalence of intra-articular mineralization on knee computed tomography: the multicenter osteoarthritis study
Authors' conclusion
CT of the knee provides greater visualization of intra-articular mineralization than radiographs and allows better localization of the crystal deposition within the joint.
Study context
- Population
- Participants of the Multicenter Osteoarthritis (MOST) Study at the 12th year visit (56.7% female, mean age 61.1 years, mean Body Mass Index (BMI) 28.8 kg/m²)4,140 bilateral knees
- Participants
- 2,070 participants
- Exposure
- Computed tomography (CT) vs radiographs for detection of intra-articular mineralization
- Outcome
- Prevalence of CT-detected intra-articular mineralization
Methodological detailsmulticenter, bilateral knee CT, Boston University Calcium Knee Score (BUCKS) scoring

Main finding
As reported in the abstract
Prevalence of intra-articular mineralization (knees)
Observational data: associations, not effects.
Further findings
Hyaline articular and meniscus mineralization by subgroup
- Increased with age and KL grade
- Similar by sex, BMI categories, and with vs without frequent knee pain
Distribution of mineralization by compartment
- All three (medial/lateral tibiofemoral and patellofemoral) compartments
- 3.1%
- Patellofemoral compartment in isolation
- 1.4%
