ACL Injury

Anterior Cruciate Ligament (ACL) injuries are among the most serious knee injuries in sport. Our experienced sports physiotherapists provide comprehensive rehabilitation programs, whether you choose surgical or conservative management, focusing on safe return to sport.

Understanding ACL Injuries

Injury Mechanism

• Non-Contact: 70% occur without direct contact
• Pivoting/Cutting: Sudden direction changes
• Landing: Poor landing mechanics from jumps
• Deceleration: Rapid stopping movements

Associated Injuries

• Meniscus tears (50% of cases)
• MCL sprains
• Bone bruising
• Cartilage damage
• Other ligament injuries

Initial Management

Acute Phase (0-2 weeks)

• Protection: Bracing if required
• Pain/Swelling Control: Ice, compression, elevation
• Early Movement: Gentle range of motion exercises
• Weight Bearing: As tolerated with crutches
• Quadriceps Activation: Preventing muscle shutdown

Pre-Surgery Preparation

If surgery is planned:

• Reduce swelling completely
• Restore full knee extension
• Improve knee flexion to 90°+
• Activate quadriceps strongly
• Optimize general fitness

Rehabilitation Phases

Phase 1: Recovery (Weeks 0-6)

• Goals: Control swelling, restore movement, protect graft
• Exercises: Range of motion, isometric strengthening
• Weight Bearing: Progressive loading
• Criteria: Full extension, minimal swelling

Phase 2: Strength (Weeks 6-12)

• Goals: Build strength foundation, normalize gait
• Exercises: Progressive resistance training
• Functional: Bike, pool activities
• Criteria: Good quadriceps control, 120° flexion

Phase 3: Neuromuscular (Weeks 12-20)

• Goals: Power development, movement quality
• Exercises: Plyometrics, agility foundations
• Running: Straight line progression
• Criteria: 80% strength symmetry

Phase 4: Return to Sport (Weeks 20+)

• Goals: Sport-specific skills, confidence
• Training: Cutting, pivoting, sport drills
• Testing: Comprehensive return to sport battery
• Criteria: 90% strength, pass functional tests

Conservative Management

For non-surgical cases:

• Comprehensive strengthening program
• Neuromuscular training focus
• Activity modification education
• Potential for full return to modified activities
• Long-term knee protection strategies

Post-Surgical Rehabilitation

Graft Types

Different protocols for:

• Hamstring tendon autograft
• Patella tendon autograft
• Quadriceps tendon autograft
• Allograft (donor tissue)

Key Milestones

• Week 2: Full extension achieved
• Week 6: Full weight bearing
• Week 12: Begin running program
• Month 6: Sport-specific training
• Month 9-12: Return to competition

Return to Sport Testing

Strength Testing

• Quadriceps strength >90% of uninjured leg
• Hamstring strength symmetry
• Hip and core strength assessment

Functional Testing

• Single hop distance
• Triple hop distance
• Cross-over hop
• 6-meter timed hop
• Agility T-test

Psychological Readiness

• ACL-Return to Sport after Injury scale
• Fear of re-injury assessment
• Confidence evaluation

Prevention Strategies

Neuromuscular Training

• Landing mechanics training
• Cutting technique improvement
• Balance and proprioception
• Core strengthening
• Hip stability focus

Risk Factor Modification

• Address biomechanical issues
• Improve strength deficits
• Enhance movement patterns
• Sport-specific conditioning

Long-Term Considerations

Re-Injury Prevention

• 15-20% re-injury rate without proper rehab
• Continued strength training essential
• Ongoing neuromuscular work
• Regular screening

Potential Complications

• Knee osteoarthritis risk
• Meniscus problems
• Persistent strength deficits
• Psychological barriers
