Lohmander et al. synthesize data from 127 ACL and 41 meniscus follow-up publications to answer a critical question. Does knee injury — and the surgery used to treat it — lead to osteoarthritis, and can surgery prevent it? This is a narrative review of long-term consequences, pathogenic mechanisms, and sources of outcome variability.
Half your ACL and meniscus patients will have arthritic knees by their 40s — and the surgery you perform will not change that trajectory.
When counseling a 22-year-old soccer player after ACL rupture, frame the reconstruction around functional goals (return to sport, stability, prevention of secondary meniscus injury). Not arthritis prevention. The data on 168 publications show no protective signal for OA, and this has not changed since a 1994 review reached the same conclusion.
When a 42-year-old presents with knee pain and an MRI showing a degenerative meniscus tear, treat the OA. Not the meniscus. Arthroscopic partial meniscectomy in this group performs no better than sham surgery. The degenerative tear is a feature of OA, not its cause.
Post-meniscectomy OA risk is modifiable: counsel patients on weight management, muscle strengthening, and the significance of finger joint OA as a marker of systemic OA predisposition. These factors are as important as the surgical decision itself.
