Post-Surgical Rehabilitation of the ACL and Meniscus Repair: The Path to a Complete Recovery

Anterior cruciate ligament (ACL) reconstruction surgery combined with meniscus repair is one of the most common orthopedic procedures for sports and traumatic knee injuries. However, the success of the operation does not end in the operating room: specialized physical therapy rehabilitation is the determining factor in recovering full knee function and preventing future complications.

Understanding the Combined Injury: ACL and Meniscus

The anterior cruciate ligament acts as the primary stabilizer of the knee, while the meniscus functions as a shock absorber and load distributor. When both structures are injured at the same time, the rehabilitation challenge doubles, especially because the healing times of the meniscus dictate the entire progressive loading protocol.

Unlike ACL reconstruction, where progression can be more predictable, meniscus repair requires strict respect for the biological repair timeline, since this structure has a limited blood supply, especially in its inner zone.

Rehabilitation Phases: An Evidence-Based Protocol

Weeks 0-2: Protection and Initial Control

In this critical phase, the focus is on:

• Absolute protection of the repaired meniscus through weight-bearing restriction
• Swelling control and post-surgical pain management
• Early recovery of range of motion (0-90°)
• Early quadriceps muscle activation without resistance

Permitted load: 0-25% of body weight with crutches and a brace locked in extension. Early mobilization prevents joint stiffness without compromising the meniscal repair.

Weeks 3-6: Meniscal Healing Phase

This stage respects the critical healing period of the meniscus (6-8 weeks). During these weeks:

• Gradual progression to full range of motion (0-130°)
• Introduction of low-impact closed-chain exercises
• Proprioceptive work in unloaded and partial weight-bearing positions
• Progressive isometric strengthening

Permitted load: Progression from 25% to 50% of body weight between weeks 3-4, reaching 75% by week 6.

Weeks 7-12: Consolidation and Strengthening

Once the critical meniscal healing phase is over:

• Full weight-bearing without crutches (usually weeks 8-10)
• Progressive muscle strengthening with resistance
• Dynamic stability and neuromuscular control exercises
• Introduction of low-impact functional activities

This period marks the transition toward more demanding exercises, always respecting the individual response of the repaired tissue.

Weeks 13-24: Advanced Functional Return

• Specific strength and power training
• Progressive plyometric exercises
• Sport-specific movements from low to high impact
• Preparation for return to sport

Return to contact or pivoting sports typically occurs between 9-12 months, after functional assessments confirm strength symmetry >90%, optimal neuromuscular control, and absence of symptoms.

Why Is Specialized Physical Therapy Indispensable?

Rehabilitation of this combined injury is not a standard protocol that just anyone can follow. It requires:

1. Deep knowledge of biological timelines: Knowing exactly when to progress the load so as not to compromise the meniscal repair is fundamental.

2. Continuous evaluation and individualized adjustments: Each patient heals at their own pace. Factors such as age, tissue quality, surgical technique, and the location of the meniscal injury influence progression.

3. Prevention of complications: Arthrofibrosis (joint stiffness), persistent quadriceps weakness, and residual instability are complications that can be avoided with proper physical therapy.

4. Optimization of the ACL graft: The graft needs to go through a "ligamentization" process that lasts months. Inadequate loading can compromise its integration.

5. Safe return to sport: Returning too soon is the leading cause of re-rupture. A specialized physical therapist uses objective criteria to authorize the return.

Warning Signs During Rehabilitation

It is crucial to seek immediate consultation if you experience:

• Significant increase in pain or swelling
• A feeling of instability or the knee "giving way"
• Joint locking or painful clicking
• Loss of previously gained range of motion
• Signs of infection (fever, redness, excessive warmth)
