What is the recommended daily walking distance for a patient 3 months post Anterior Cruciate Ligament (ACL) reconstruction and Meniscus repair surgery?

Walking Recommendations After ACL Reconstruction and Meniscus Repair at 3 Months

At 3 months post ACL reconstruction and meniscus repair, patients should follow a goal-based approach to walking distance rather than a strict kilometer limit, gradually progressing based on functional milestones and absence of pain or swelling.

Current Rehabilitation Approach

Modern rehabilitation after ACL reconstruction has shifted from strictly time-based protocols to goal-based rehabilitation that focuses on achieving specific functional milestones 1. This approach recognizes individual differences in neuromotor learning and healing after surgery.

Walking Progression Guidelines

At 3 months post-surgery, patients are typically in the intermediate rehabilitation phase where:

• Full weight-bearing is generally permitted and encouraged 1
• Both open and closed kinetic chain exercises are recommended 1
• Neuromuscular training should be incorporated alongside strength training 1

Determining Appropriate Walking Distance

Rather than prescribing a specific kilometer limit, walking distance should be guided by:

1. Pain response: Walking should not increase knee pain during or after activity
2. Swelling response: No increased joint effusion following walking
3. Quality of movement: Maintaining proper gait mechanics without limping
4. Fatigue level: Stopping before significant quadriceps fatigue develops

Monitoring and Progression

• Start with shorter distances: Begin with 15-20 minute walks (approximately 1-1.5 km)
• Progressive overload: Increase distance by 10-15% weekly if no adverse reactions
• Split sessions: Consider multiple shorter walks rather than one long walk
• Surface considerations: Begin on flat, even surfaces before progressing to uneven terrain
• Monitor symptoms: Track pain, swelling, and function after each walking session

Important Considerations

• Graft protection: At 3 months, the ACL graft is still undergoing biological remodeling and is vulnerable to excessive forces 1, 2
• Meniscus healing: The repaired meniscus requires continued protection from excessive shear forces
• Balance deficits: Research shows proprioception and balance remain impaired at 2 months post-surgery 3, suggesting careful progression is needed

Warning Signs to Reduce Walking Distance

• Increased knee pain lasting more than 24 hours after walking
• Joint swelling or effusion
• Development of a limp or altered gait pattern
• Feeling of instability during walking
• Increased pain at the meniscus repair site

Complementary Activities

While gradually increasing walking distance, patients should also focus on:

• Quadriceps and hamstring strengthening exercises 1
• Neuromuscular control and proprioception training 1
• Balance exercises on stable and unstable surfaces 1
• Proper gait retraining to avoid compensatory patterns

Return to Running Considerations

As walking distance increases, patients may begin preparing for return to running, which typically occurs between 3-4 months post-surgery. The International Knee Documentation Committee (IKDC) score can help predict successful return to running, with scores above 64 associated with better outcomes 4.

By following these guidelines and listening to your body's response to increased activity, you can safely progress your walking distance while protecting your surgical repairs and optimizing long-term outcomes.
