Self-reported function corresponds to bone bruise radiographic severity

In the moment: Knee

Self-reported functional scores in patients with bone bruise lesions associated with anterior cruciate ligament (ACL) injury are consistent with severity classifications based on radiographic presentation, according to findings presented in late June at the NATA meeting.

Researchers from the University of Kentucky in Lexington graded bone bruise lesions in 51 individuals who had sustained ACL injuries, based on the appearance of the lesions on magnetic resonance imaging. According to the Costa-Paz classification system, one lesion was Grade 1 (signal change sub­adjacent to the articular surface), 28 were Grade 2 (signal change that kisses the articular surface), and 22 were Grade 3 (signal change at the articular surface).

Compared to the individuals with Grade 2 lesions, those with Grade 3 lesions had significantly poorer function based on the sports and quality of life subsections of the KOOS (Knee Osteoarthritis Outcome Score) test. Patients with more severe le­-sions reported more difficulty
with sports-related movements, aware­ness of knee problems, lifestyle modifications, lack of confidence in the knee, and overall function.
