This systematic review and meta-analysis examined intra-articular injuries in 37,423 anterior cruciate ligament reconstructions (ACLR), comparing primary and revision procedures. The study found that revision ACLR had 1.64 times higher odds of meniscal injury and over 3 times higher odds of chondral lesions, particularly severe injuries in the trochlea and medial compartments.
Key findings
- Revision ACLR had 1.64 times higher odds of meniscal injury (OR, 1.64; 95% CI, 1.12-2.41).
- Chondral lesions were over 3-fold more prevalent in revisions (OR, 3.53; 95% CI, 2.71-4.60).
- High-grade chondral lesions were consistently more common in revisions, with progression in up to 26% of cases.
Why it matters
Understanding the prevalence and severity of intra-articular injuries in ACLR can inform surgical planning and prognosis, particularly in revision cases where the burden of disease is significantly higher.
