Cartilage and meniscus lesions common in OA sufferers

Cartilage and meniscus lesions are common in middle-aged patients suffering from osteoarthritis of the knee, according to new research.

A study published in the February issue of Radiology shows that this is particularly true if patients are physically active.

The researchers behind the new paper, showed that patellar cartilage T2 values correlated with the severity and grade of such lesions and that the correlation was clinically significant.

Christoph Stehling, leader of the research team behind the study, said: "Our results indicate that T2 relaxation time at the patella may be a marker for internal joint derangement in terms of cartilage and meniscal lesions."

The researchers found that cartilage legions were evident in 79 per cent of osteoarthritic knees following magnetic resonance imaging, while 45 per cent showed evidence of meniscal legions.

Metin Gurcan, senior author of the work and an assistant professor of biomedical informatics, recently told the Osteoarthritis and Cartilage journal that computer imaging of the meniscus could be used to reliably image knees ahead of orthopaedic surgery.
