What we do
About our project
A ‘meniscal pathway’ to knee OA was implicated by a loss of meniscal function due to damage or extrusion, leading to cartilage loss, subchondral bone changes, bone marrow lesions and synovitis, eventually resulting in pain and definite OA. Therefore, it is important to assess the presence of meniscal pathologies when studying early stage knee OA.
We hypothesize that meniscus pathologies (e.g. extrusion, swelling, tear) play an essential role in knee OA development.
Data from the Prevention of knee Osteoarthritis in Overweight Females study and Rotterdam Study will be used.
The PROOF cohort included 407 women with a BMI ≥27 kg/m2, free of OA related symptoms.
The Rotterdam Study (RS) is a population-based prospective cohort study ongoing since 1990, which include 3 subpopulation.
The outcome measure will be the incidence of clinical and radiographic knee OA. All menisci at all time-points were automatically segmented to obtain the meniscal volume and delta-volumes. Generalized estimating equations were used to evaluate associations between the volume measures and the outcomes. Structural equation model was built to investigate the interplay between different meniscus pathologies and radiographic OA outcome.
Results will be validated using data from the Rotterdam Study, the OAI, and CHECK.
Our research focus
The primary outcome measure was the incidence of knee OA which include radiographic and clinical defined OA.
