What factor is likely to worsen symptoms in osteochondritis dissecans?

In osteochondritis dissecans, symptoms can worsen due to increased mechanical stress on the affected area, particularly the joint where the condition is present. Physical activity, which involves weight-bearing or repetitive motion, can exacerbate symptoms such as pain and swelling. The condition, characterized by the separation of bone and cartilage, can lead to joint instability and further injury with activity. It is imperative for individuals with this condition to manage their activity levels to prevent aggravation of symptoms.

Other factors, such as rest and inactivity, are generally considered to alleviate symptoms, while cold weather can influence comfort levels but is not a direct aggravator of the condition itself. A poor diet may have indirect effects on overall health but does not specifically exacerbate osteochondritis dissecans symptoms. Therefore, the engagement in physical activities is likely to worsen symptoms due to the physical stress placed on the compromised joint.
