After ACL reconstruction, NMES is recommended at approximately which postoperative timeframe?

• A. 2-4 weeks
• B. 6-8 weeks
• C. 12-16 weeks
• D. 24 weeks

Answer: (B)

The focus here is on timing NMES to support quadriceps activation without compromising graft healing. After ACL reconstruction, swelling and joint inhibition make it hard for the quad to fire reliably. Early in rehab the priority is protecting the graft, controlling swelling, and restoring range of motion. By about six to eight weeks, the graft has progressed enough to tolerate light strengthening, and patients commonly begin more formal quadriceps loading. Introducing NMES at this stage helps augment the attempted contractions, counteracting arthrogenic inhibition, and supports neuromuscular re-education as you move into progressive resistance training. It’s too early to push this level of stimulation in the first couple of weeks when healing is acute, and waiting too long means missing an opportunity to address quad weakness as early as possible.
