Divergent trends seen in meniscal and cartilage injuries between primary and revision ACL repair

In a community-based sample, the prevalence of articular cartilage injury increased between primary and revision ACL repair, whereas the prevalence of meniscal injury decreased, according to recent study findings.

Researchers studied 261 patients who underwent both primary and revision ACL reconstruction (ACLR) between February 2005 and September 2011 via community-based registry. Patient data (sex, age, race and BMI), procedure characteristics and descriptive statistics (medians, interquartile ranges, frequencies and proportions) were the metrics used for evaluation.
Overall, 256 patients required revision ACLR due to instability, and the remaining five were due to infection.

Cartilage injuries nearly doubled (14.9% to 31.8%) from primary to revision ACLR, whereas meniscal tears decreased overall from 54.8% at primary ACLR to 43.7% at revision. This trend was also reflected in lateral meniscus tears (32.2% at primary, 18.4% at revision), though medial meniscus tears were observed to be the same (32.6%) at both primary and revision ACLR, according to the researchers.

A 70.8% prevalence of meniscus tear in revision was observed in patients who had meniscus fixation during primary ACLR.
