"Loosening of the cruciate ligament"


Hello Dr.
Lee, what rehabilitation methods are available for a "loose" anterior cruciate ligament (ACL)? How many months does it typically take to return to playing with a racket and enjoying the game on the court?

Hello: The cruciate ligaments consist of the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL).
The treatment for cruciate ligament injuries depends on whether there is a complete tear, significant laxity, or mild laxity, which will determine whether surgical or conservative treatment is appropriate.
Treatment options may also vary based on the patient's lifestyle, age, and occupation.
For example, if you are a young person who enjoys sports and wishes to return to the field, aggressive treatment is recommended.
An MRI (Magnetic Resonance Imaging) scan can confirm whether the cruciate ligament is completely torn or partially torn, and a clinical examination by a physician can assess knee stability (with anterior-posterior displacement greater than 1 cm).
Generally, if the MRI shows a complete tear of the cruciate ligament and the clinical examination indicates anterior-posterior displacement greater than 1 cm, along with noticeable symptoms in daily life (such as weakness or knee pain), it is strongly advised to discuss the possibility of cruciate ligament reconstruction surgery with an orthopedic surgeon.
Conversely, if the MRI indicates only laxity of the cruciate ligament and the clinical examination shows anterior-posterior displacement not exceeding 0.5 cm, with minimal symptoms in daily life, conservative treatment is recommended.
This may include wearing a specialized brace for cruciate ligament injuries for six to eight weeks, along with rehabilitation therapy.
The rehabilitation program, led by a rehabilitation physician, will be tailored based on the MRI results (injury to the ACL or PCL) and may include quadriceps or hamstring training, hydrotherapy, posture correction, etc.
This process generally takes two to three months.
In summary, first consult an orthopedic surgeon.
If a cruciate ligament issue is suspected during the clinical examination, proceed with an MRI scan.
Based on the results, discuss the treatment plan with the orthopedic surgeon.
If rehabilitation is needed, the orthopedic surgeon can refer you to a rehabilitation specialist for a more comprehensive treatment approach.
Finally, I wish you all the best.
Director of Orthopedics, Keelung Hospital, Li Wen-Lin.

More Info


Rehabilitation after an Anterior Cruciate Ligament (ACL) injury is a critical process that can significantly impact an athlete's return to sports. The timeline for returning to sports, particularly activities like badminton, can vary based on the severity of the injury, the type of treatment received, and the individual's commitment to rehabilitation.


Understanding ACL Injury
The ACL is one of the key ligaments that help stabilize the knee joint. An ACL injury can range from a mild sprain to a complete tear. Symptoms often include pain, swelling, instability of the knee, and a feeling of "giving way." If the ACL is "loose" or "unstable," it may indicate that the ligament is either partially torn or has not healed properly.


Rehabilitation Methods
1. Initial Phase (0-2 weeks post-injury):
- Rest and Ice: Immediately after the injury, it's crucial to rest the knee and apply ice to reduce swelling.

- Compression and Elevation: Using a compression bandage and elevating the leg can help manage swelling.

- Gentle Range of Motion Exercises: Start with gentle movements to maintain some flexibility in the knee.

2. Early Rehabilitation Phase (2-6 weeks):
- Physical Therapy: A physical therapist can guide you through exercises that focus on regaining range of motion and strength. This may include:
- Quadriceps and hamstring strengthening exercises.

- Balance and proprioception training.

- Low-impact Activities: Activities like cycling or swimming can help maintain cardiovascular fitness without putting too much strain on the knee.

3. Strengthening Phase (6-12 weeks):
- Progressive Strength Training: As pain decreases and range of motion improves, you can start more intensive strength training. This may include:
- Leg presses, squats, and lunges.

- Resistance band exercises targeting the knee stabilizers.

- Functional Training: Begin incorporating sport-specific movements, such as lateral movements and jumping drills, to prepare for the demands of badminton.

4. Return to Sport Phase (3-6 months):
- Sport-Specific Drills: Gradually reintroduce badminton-specific drills, focusing on agility, speed, and coordination.

- Plyometric Exercises: Incorporate jumping and landing exercises to improve strength and stability.

- Gradual Return to Play: Start with light practice sessions, progressively increasing intensity and duration.


Timeline for Return to Sports
The timeline for returning to sports after an ACL injury can vary widely. Generally, athletes can expect to return to sports between 6 to 12 months post-injury, depending on the severity of the injury and the effectiveness of the rehabilitation program. Factors that can influence this timeline include:
- Severity of the Injury: A complete tear may require surgical intervention and a longer recovery period.

- Rehabilitation Compliance: Adhering to a structured rehabilitation program can significantly enhance recovery.

- Individual Factors: Age, overall health, and previous injury history can also affect recovery time.


Conclusion
Returning to badminton after an ACL injury is a gradual process that requires patience and dedication. It's essential to work closely with a healthcare professional, such as a physical therapist or sports medicine physician, to develop a personalized rehabilitation plan. They can assess your progress and help you determine the right time to return to the court safely. Remember, rushing back to sports too soon can lead to re-injury, so it's crucial to listen to your body and follow a structured rehabilitation program.
