Overview

Systematic review identifies enhanced knee changes over time in ACL-deficient individuals, suggesting worsening anatomical condition.

Key Points

  • This research aims to systematically review MRI findings related to chronic anterior cruciate ligament deficiency in the knee.
  • Searched four databases for studies on ACL-deficient patients from inception until January 2025.
  • Included cohort studies with acute ACL tear comparisons for pooled analysis.
  • Abstracted data on demographics, injury times, and MRI findings.
  • Higher rates of medial meniscus injuries (50.3%) in chronic ACLD compared to acute injuries (36.0%).
  • Observed greater lesions in medial femoral condyle and medial tibial plateau cartilage.
  • Noted anterior medial tibial subluxation increased by +1.6 mm in chronic ACLD.
  • Chronic ACL-deficient knees demonstrated PCL buckling and ACL fragmentation.
