Which statement best represents return-to-sport testing timing after ACL reconstruction?

• A. 3-6 months
• B. 9-12 months
• C. 18-24 months
• D. 1-2 weeks

Answer: (B)

Timing for return-to-sport testing after ACL reconstruction hinges on meeting objective functional criteria rather than just counting months. Graft healing, restoration of quadriceps and hamstring strength, neuromuscular control, and movement quality typically align with a testing window around 9 to 12 months post-operation. Pushing athletes to RTS earlier increases the risk of graft failure or reinjury, especially in pivoting or high-demand sports. By roughly 9–12 months, many patients achieve adequate strength symmetry (often around 90% or greater) and pass functional tests such as hop tests and agility drills, along with full range of motion and minimal effusion, making this window the most balanced and commonly recommended timeframe. Earlier time points (3–6 months) are usually too soon, while waiting until 18–24 months is longer than necessary for most athletes, though individualization remains important.
