What describes the typical progression strategy after ACL reconstruction?

• A. Phase progression from protected ROM to progressive strengthening, with return-to-sport testing around 9–12 months; avoid high loads until graft maturation.
• B. Immediate full ROM and strengthening with return-to-sport at 3 months.
• C. Only stretching and no strengthening for the first year.
• D. Immediate high-load plyometrics within 6 weeks.

Answer: (A)

Rehab after ACL reconstruction follows a phased plan that protects the healing graft while gradually rebuilding strength and function. In the early stages the focus is on controlled motion and reducing swelling, with the knee moved carefully through a protected range of motion to encourage healing without stressing the reconstruction. As healing progresses, the program introduces progressively challenging strengthening work—starting with bodyweight and closed-kinetic-chain exercises, then adding resistance, balance, and neuromuscular training. The goal is to restore symmetry between the injured and uninjured leg, improve knee control, and rebuild confidence in movement.

A return-to-sport plan is typically delayed until the graft has matured enough to handle high loads. This maturation process is why return-to-sport testing is commonly scheduled around 9–12 months after surgery, and why high-load activities are avoided early on. Pushing for full activity or advanced plyometrics too soon increases the risk of graft failure or re-injury.

The other approaches are not aligned with this evidence-based progression. Jumping into full ROM and strengthening with return at 3 months is too aggressive for most grafts and can jeopardize healing. Limiting activity to stretching for an entire year leaves the leg weak and is not protective of long-term function. Initiating high-load plyometrics within 6 weeks subjects the healing graft to stresses it isn’t ready to tolerate.
