💡 ACL Reconstruction and Osteoarthritis: Rethinking a Long-Held Assumption
It is commonly assumed that anterior cruciate ligament (ACL) reconstruction is necessary to reduce the risk of post-traumatic knee osteoarthritis (OA) following ACL rupture. However, emerging evidence challenges this long-standing belief.
A 2023 meta-analysis including three randomized controlled trials (n = 343 injured knees) compared long-term osteoarthritis outcomes between surgically reconstructed and non-surgically managed ACL injuries.
Surprisingly, the relative risk of developing radiographic knee osteoarthritis was nearly twice as high in the surgical group compared with those managed conservatively.
These findings suggest that ACL reconstruction does not confer a protective effect against osteoarthritis, and may, in some cases, be associated with a higher OA risk.
Several mechanisms may help explain this observation:
👉 Surgical trauma and altered joint biology
👉 Persistent or altered joint loading patterns post-reconstruction
👉 Incomplete restoration of normal knee kinematics
👉 Reduced long-term exposure to progressive, high-quality neuromuscular rehabilitation
From a physiotherapy perspective, this reinforces the importance of:
👉 Viewing ACL rupture as a whole-joint injury, not merely a ligament problem
👉 Prioritizing progressive, individualized rehabilitation focused on movement quality, strength, and load management
👉Recognizing that surgical reconstruction should not be positioned as an osteoarthritis-prevention strategy
🔆 The key clinical question may no longer be “Does surgery prevent arthritis?”
But rather:
👉Which patients truly benefit from reconstruction—and how can rehabilitation (physiotherapy) optimize long-term joint health regardless of the treatment pathway?
