Most MCL tears (especially Grade 1 and 2) heal well with non-surgical treatment, and physiotherapy plays a crucial role in rehabilitation. Advanced physiotherapy focuses on a structured, progressive approach to restore full function, strength, and stability, and prevent re-injury.
Phases of Rehabilitation and Advanced Techniques:-
Phase 1: Acute/Protection Phase (Immediately Post-Injury – typically 0-2 weeks)
- Goals: Reduce pain and swelling, protect the injured ligament, and maintain some range of motion.
- Interventions:-
- RICE Protocol: Rest, Ice (cryotherapy to reduce inflammation, apply for 20 mins multiple times a day), Compression (elastic bandage or compression sleeve), Elevation.
- Bracing/Immobilization: A hinged knee brace may be used to protect the MCL from valgus (inward) stress, especially for Grade 2 or 3 tears. Weight-bearing may be restricted initially, often with crutches.
- Electrotherapy: Modalities like TENS (Transcutaneous Electrical Nerve Stimulation) or high-intensity laser therapy to help with pain modulation and tissue healing.
- Gentle Range of Motion (ROM) Exercises: Passive or active-assisted knee flexion and extension within pain-free limits (e.g., heel slides, prone hangs).
- Isometric Exercises: Gentle muscle contractions without moving the joint (e.g., quadriceps sets, hamstring sets) to prevent muscle atrophy.
Phase 2: Subacute/Early Strengthening Phase (2-6 weeks)
- Goals: Restore full range of motion, improve muscular activation and strength, and begin proprioception training.
- Interventions
- Progressive ROM Exercises: Increasing knee flexion and extension, including exercises like wall slides, heel slides with towel assist.
- Stretching: Gentle stretches for quadriceps, hamstrings, and calves to maintain flexibility.
- Closed Kinetic Chain Exercises: These are exercises where the foot remains in contact with a surface, which are generally safer for the knee joint.
- Mini Squats/Wall Squats: Gradually increasing depth as tolerated, focusing on proper knee alignment.
- Leg Presses (double leg, then single leg): With appropriate resistance.
- Step-Ups/Step-Downs: Starting with low steps and progressing.
- Bridge Exercises: To strengthen glutes and hamstrings.
- Proprioception Training: Exercises to improve balance and body awareness, which is crucial for stability.
- Single-Leg Balance: Starting on a stable surface, then progressing to unstable surfaces (foam pad, wobble board, BOSU ball).
- Balance Squats: Performing squats while maintaining balance.
- Manual Therapy: Patellar mobilizations to ensure the kneecap moves freely, soft tissue release techniques for surrounding muscles.
Phase 3: Rehabilitation/Dynamic Stability Phase (6-12 weeks)
- Goals: Develop dynamic knee stability, enhance strength, and improve endurance for functional activities.
- Interventions:
- Advanced Strengthening:
- Lunges (forward, reverse, lateral): Essential for building strength and stability in different planes of movement.
- Single-Leg Deadlifts: To strengthen hamstrings and glutes while improving balance.
- Calf Raises: For ankle and lower leg strength.
- Resistance Band Exercises: For targeted strengthening of hip abductors and adductors (e.g., crab walks with a band).
- Neuromuscular Drills: Exercises that challenge coordination and reaction time.
- Lateral Shuffles: To improve side-to-side stability.
- Agility Ladder Drills: For quick footwork and changes of direction.
- Controlled Pivoting Drills: Gradually reintroducing rotational movements with caution.
- Cardiovascular Conditioning: Stationary cycling, elliptical training, or swimming (avoiding breaststroke kick initially) to maintain fitness without stressing the knee.
- Plyometrics (controlled): For power and explosiveness, introduced cautiously for athletes (e.g., jump squats, lateral hops, box jumps with soft landings).
Phase 4: Advanced Functional Training/Return to Sport (12+ weeks, variable)
- Goals: Restore full sport-specific or activity-specific function, prevent re-injury, and ensure readiness for high-impact activities.
- Interventions
- Sport-Specific Drills: Mimicking movements and actions required in the patient’s sport or activity.
- Cutting Drills: Gradually increasing speed and intensity of changes in direction.
- Deceleration Drills: Training the muscles to absorb impact effectively.
- Jumping and Landing Mechanics: Refining technique to reduce stress on the knee.
- Progressive Load Management: Gradually increasing the volume, intensity, and complexity of training.
- Strength and Conditioning: Continued focus on overall lower body strength, core stability, and endurance.
