The Complete ACL Return-to-Sport Guide

Rebuild strength, restore confidence, and perform better than before.

An ACL injury can feel like a long road back — surgery, rehab, and the slow climb to confidence.

At Movement Rx, we believe ACL recovery isn’t just about getting the knee pain-free; it’s about rebuilding the whole athlete so you can return stronger and more prepared.

Understanding the ACL and Why It Takes Time

The anterior cruciate ligament (ACL) stabilises the knee during twisting, landing, and change-of-direction.

When it tears, stability and control are lost. Rebuilding those systems requires a structured process that restores movement quality, strength, and trust.

The Five Phases of ACL Rehabilitation

Phase 1 – Acute Recovery (Weeks 1–4)

Goal: Reduce swelling and regain full knee extension

• Pain control
• Early range of motion
• Quadriceps activation

Outcome: Walking normally without aids and a calm, mobile knee

Phase 2 – Strength Foundations (Weeks 4–12)

Build base strength through:

• Leg press
• Hamstring curls
• Glute activation
• Body-weight control drills

Load is introduced gradually, always prioritising movement quality over volume.

Phase 3 – Return to Running (Months 3–6)

Before running volume is introduced, we restore running mechanics and posture.

Focus areas:

• Running technique drills (marching, skipping, wall drills)
• Glute, hamstring, and calf activation
• Gradual progression from drills → intervals → straight-line running

Objective checks:

• Strength and symmetry ≥ 90%
• Stable single-leg landing
• Balanced load on both limbs (force plate testing)

👉 Our philosophy: retrain how you run before adding volume.

Phase 4 – Power, Braking & Change-of-Direction (Months 6–9)

This phase rebuilds athletic performance.

Focus areas:

• Eccentric strength and braking control
• Plyometrics (jump-land-stick, single-leg bounds)
• Change-of-direction mechanics

Force-plate profiling helps identify asymmetries that aren’t visible to the eye.

Phase 5 – Return to Sport (9–12+ Months)

Testing determines readiness—not the calendar.

We assess:

• Strength ratios
• Hop testing
• Force-plate asymmetry

Then progress into:

• Reactive drills
• Fatigue-based testing
• Decision-making under pressure

Common Mistakes We See in ACL Rehab

Poor Braking Systems

Many programs rebuild acceleration but neglect deceleration.

Without strong braking, the knee absorbs excessive load during landing and stopping—significantly increasing re-injury risk.

Hidden Asymmetry

Even when movement looks balanced, athletes often overload the non-surgical leg.

Force-plate data regularly reveals discrepancies that aren’t visible otherwise.

Poor Change-of-Direction Mechanics

Returning to sport without retraining cutting and rotational control leads to inefficiency and increased knee stress.

How We Measure Readiness at Movement Rx

We remove guesswork by combining:

• Force-plate testing (landing, symmetry, braking metrics)
• Strength testing (quads, hamstrings, hips, calves)
• Hop and agility testing
• Performance tracking (speed, acceleration, COD efficiency)

This provides a clear picture of progress and what’s required to safely return.

👉 As part of ACL rehabilitation, return to sport testing plays a key role in assessing strength, movement, and readiness to return safely.

Your Recovery Timeline (Guide Only)

Every recovery is individual—readiness is proven by testing, not time.

The Movement Rx Difference

• Objective testing — we measure, not guess
• Running mechanics restored before overload
• Force-plate-guided strength and braking training
• Comprehensive strength testing across the whole kinetic chain
• Progressive change-of-direction retraining
• Performance-focused rehab through to full return

We work with athletes across Brisbane North, Kippa-Ring and Redcliffe, combining physiotherapy, performance testing, and coaching.
