Anterior cruciate ligament (ACL)
Hello, doctor.
I would like to ask about a torn anterior cruciate ligament (ACL) in my left knee that cannot be surgically repaired at the moment.
What types of assistive devices are currently available that would be suitable? What movements should I absolutely avoid and be cautious about? I read that I can perform large muscle group exercises; can I do strength training to enhance muscle strength?

After an anterior cruciate ligament (ACL) injury, it is common to use braces that limit the range of motion of the joint; however, the choice should be based on individual circumstances and assessed by a professional.
Following an ACL injury, it is important to avoid sudden stops with the affected leg and to reduce squatting or kneeling movements to prevent further strain on the joint.
Strengthening the quadriceps and gluteal muscles can help compensate for function and reduce the risk of re-injury to the anterior cruciate ligament.

More Info
Recovering from an ACL (anterior cruciate ligament) injury can be a challenging process, especially when surgery is not immediately possible. The focus during this time should be on managing pain, maintaining mobility, and preparing for eventual surgical intervention. Here are some recommendations regarding aids, exercises, and precautions during your recovery.
Best Aids for ACL Injury Recovery
1. Knee Brace: A knee brace can provide stability and support to the injured knee. It helps to limit excessive movement that could worsen the injury. Look for a brace that offers both support and comfort, allowing for some range of motion while protecting the knee.
2. Ice Packs: Applying ice packs to the injured area can help reduce swelling and alleviate pain. It is advisable to ice the knee for 15-20 minutes every few hours, especially after any activity.
3. Compression Wraps: Using compression wraps can help manage swelling and provide support. Make sure not to wrap too tightly, as this can impede circulation.
4. Physical Therapy Tools: Resistance bands and balance boards can be beneficial for rehabilitation exercises. These tools can help strengthen the muscles around the knee and improve stability.
5. Assistive Devices: Crutches or a walker may be necessary if weight-bearing is painful or if you feel unstable. They can help you move around safely while minimizing stress on the knee.
Do's and Don'ts for Rehab
#
Do's:
- Engage in Gentle Range of Motion Exercises: Focus on gentle movements that do not cause pain. This can include straight leg raises and heel slides to maintain mobility without stressing the ACL.
- Strengthening Exercises: Once you have the go-ahead from your healthcare provider, you can begin strengthening exercises for the quadriceps and hamstrings. Exercises like leg presses and hamstring curls can be beneficial, but they should be done with caution and under supervision if possible.
- Low-Impact Activities: Activities such as swimming or cycling on a stationary bike can help maintain cardiovascular fitness without putting excessive strain on the knee.
- Consult a Physical Therapist: A physical therapist can provide a tailored rehabilitation program that considers your specific injury and recovery goals.
#
Don'ts:
- Avoid High-Impact Activities: Activities that involve jumping, running, or pivoting should be avoided, as they can exacerbate the injury and delay healing.
- Do Not Ignore Pain: If an exercise causes pain, stop immediately. Pain is a signal that something may be wrong, and pushing through it can lead to further injury.
- Avoid Prolonged Immobilization: While rest is important, keeping the knee immobilized for too long can lead to stiffness and weakness. Gentle movement is essential.
- Do Not Skip Follow-Up Appointments: Regular check-ups with your healthcare provider are crucial to monitor the healing process and adjust your rehabilitation plan as needed.
Strength Training Considerations
While you can engage in strength training, it is essential to focus on exercises that do not put undue stress on the knee. Here are some guidelines:
- Focus on Upper Body and Core: You can perform upper body exercises and core strengthening without involving the knee. This helps maintain overall fitness.
- Lower Body Exercises: When doing lower body exercises, avoid any that require bending the knee excessively or putting weight on it. Instead, focus on isometric exercises that engage the muscles without moving the joint.
- Progress Gradually: As your knee improves, gradually increase the intensity of your workouts. Always listen to your body and consult with a physical therapist or trainer who understands ACL injuries.
In conclusion, while recovering from an ACL injury without surgery, it is crucial to use appropriate aids, engage in safe exercises, and avoid activities that could worsen the injury. Working closely with healthcare professionals will ensure a safe and effective rehabilitation process, preparing you for eventual surgery and a full return to activity.
