Issues related to anterior cruciate ligament (ACL) sprains caused by car accidents?


Hello, about a month and a half ago, I sustained a sprain of the anterior cruciate ligament (ACL) due to a car accident.
During my last follow-up appointment, the doctor mentioned that I could start exercising in about two weeks.
Currently, I can run and jump, and I don't feel any significant discomfort while playing basketball, but my knee feels a bit unstable.
I am unable to perform a full squat, and sometimes daily activities feel uncomfortable and stiff.
After exercising, I experience soreness or tightness in my knee for a day or two (it hurts when transitioning between bending and straightening), which makes movement quite inconvenient.
After resting for a few days, the discomfort subsides.
What could be the issue? Are there any methods to improve this condition? Should I stop exercising or take any specific measures? How can I determine if my knee is in a condition suitable for sports (like basketball)? I am concerned that my knee condition may worsen.
Thank you!

Hello, an injury to the anterior cruciate ligament (ACL) often accompanies tears of the cruciate ligaments and meniscal cartilage damage.
It is advisable for you to undergo further magnetic resonance imaging (MRI) examination.

More Info


ACL (Anterior Cruciate Ligament) injuries are common after car accidents, especially when there is a sudden impact or twisting motion of the knee. The symptoms you are experiencing, such as knee instability, difficulty with full squats, and discomfort during daily activities, are indicative of potential issues with the ligament or surrounding structures. Here’s a comprehensive overview of ACL injuries, their symptoms, and recovery tips.


Symptoms of ACL Injuries
1. Instability: A feeling that the knee may give way, especially during activities that involve pivoting or sudden changes in direction.

2. Pain and Swelling: Pain may be localized around the knee, and swelling can occur shortly after the injury. This can lead to stiffness and difficulty in moving the knee.

3. Limited Range of Motion: Difficulty in fully bending or straightening the knee can be a sign of swelling or damage to the joint.

4. Discomfort During Activity: As you mentioned, activities like running, jumping, or playing basketball may cause discomfort or a "tight" feeling in the knee.


Recovery Tips
1. Rest and Ice: After any activity that aggravates your knee, it’s essential to rest and apply ice to reduce swelling and pain. Ice should be applied for 15-20 minutes every few hours as needed.

2. Physical Therapy: Engaging in a structured rehabilitation program with a physical therapist can significantly improve your recovery. They can provide exercises tailored to strengthen the muscles around the knee, improve stability, and enhance your range of motion.

3. Strengthening Exercises: Focus on strengthening the quadriceps, hamstrings, and calf muscles. Exercises such as leg lifts, hamstring curls, and calf raises can be beneficial. However, ensure that these exercises do not cause pain.

4. Balance and Proprioception Training: Incorporate exercises that improve balance and proprioception, such as standing on one leg or using a balance board. This can help enhance knee stability.

5. Gradual Return to Activity: As you feel more comfortable, gradually reintroduce activities like running and jumping. Start with low-impact exercises and slowly progress to higher-impact activities. Pay attention to your body’s signals; if you experience pain or instability, it may be a sign to scale back.

6. Use of Braces: Depending on your doctor’s advice, using a knee brace during activities may provide additional support and stability.


When to Seek Further Medical Attention
If you experience any of the following, it’s crucial to consult your healthcare provider:
- Persistent pain or swelling that does not improve with rest and ice.

- A significant increase in knee instability or giving way.

- Difficulty performing daily activities due to knee discomfort.

- Any new symptoms, such as locking or catching sensations in the knee.


Conclusion
Your current symptoms suggest that while you may be on the road to recovery, there might still be underlying issues that need to be addressed. It’s essential to listen to your body and not push through pain, as this can lead to further injury. If you have concerns about your knee's stability or pain levels, it may be wise to consult with your physician or a sports medicine specialist for a thorough evaluation, which may include imaging studies like an MRI to assess the ACL and surrounding structures.

In summary, ACL injuries require careful management and rehabilitation. With the right approach, you can improve your knee function and return to activities like basketball safely. Always prioritize your health and recovery over immediate return to sports.
