Kneecap contusion and anterior cruciate ligament (ACL) injury?


Hello Doctor, I had an MRI yesterday, and the orthopedic surgeon told me that I have a torn anterior cruciate ligament (ACL).
However, I found online that there are different grades of tears, and the surgeon mentioned that a tear requires reconstruction.
I'm unsure if my ACL is completely torn or just a partial tear.
If the ACL is not reconstructed, what problems might I face in the future?
It has been over a month since my car accident, and the doctor initially suspected a meniscus injury.
After the MRI, the doctor confirmed that the meniscus is fine, and the pain I am experiencing is due to a bone contusion.
The normal imaging appears black, but my area shows white, which is why I still have pain when walking.
The doctor mentioned that it might take about two to three months for the bone contusion pain to subside.

Would a corticosteroid injection or high-concentration glucose injection be more effective? Lastly, I would like to ask if the pain I feel when squatting is also due to the bone contusion.
Thank you for your response, Doctor.

The anterior cruciate ligament (ACL) is responsible for the stability of the knee joint, preventing excessive forward movement of the tibia.
Once injured, it can lead to issues with knee instability.
Initially, muscle training can be attempted (for ACL tears, it is important to strengthen the hamstring muscles).
If the strength of the muscles can compensate for the function of the ligament, surgery is not necessarily required.
However, for individuals who are active in sports and find that muscle training results are insufficient to support daily activities and sports, it may be time to consider surgical reconstruction.
Thank you.

Understanding ACL injuries is crucial for effective recovery and pain management. Anterior cruciate ligament (ACL) injuries are common, especially among athletes, and they can range from mild sprains to complete tears. In your case, it seems that you have been diagnosed with a complete tear of the ACL, which typically necessitates surgical reconstruction, especially if you are active and wish to return to sports or high-level activities.


Understanding ACL Injuries
1. Types of ACL Injuries: ACL injuries are generally classified into three grades:
- Grade I: Mild sprain where the ligament is stretched but not torn.

- Grade II: Moderate sprain where the ligament is partially torn.

- Grade III: Complete tear of the ligament, which is what your doctor has indicated you have.

2. Importance of Reconstruction: If the ACL is completely torn, reconstruction is often recommended. This is because the ACL plays a vital role in stabilizing the knee joint. Without a functioning ACL, you may experience instability, particularly during activities that involve pivoting or sudden changes in direction. This instability can lead to further injuries, including damage to the meniscus or cartilage, which can result in long-term joint problems such as osteoarthritis.

3. Recovery Timeline: Recovery from ACL reconstruction typically involves several phases:
- Initial Phase (0-2 weeks): Focus on reducing swelling and regaining range of motion.

- Rehabilitation Phase (2-6 months): Gradual strengthening of the knee and surrounding muscles, along with functional training.

- Return to Sport (6-12 months): Depending on the individual’s progress, many athletes can return to their sport within 6 to 12 months post-surgery.


Pain Management and Recovery
1. Pain from Bone Bruising: The pain you are experiencing in your knee could indeed be related to bone bruising, which is common after an ACL injury. Bone bruises can take time to heal, often several weeks to months, and can cause significant discomfort during activities like walking or squatting.

2. Treatment Options:
- Physical Therapy: Engaging in a structured physical therapy program is essential. A physical therapist can guide you through exercises that promote healing, improve strength, and restore function.

- Medications: Non-steroidal anti-inflammatory drugs (NSAIDs) can help manage pain and reduce inflammation. If your pain is severe, your doctor may consider corticosteroid injections, which can provide temporary relief by reducing inflammation in the joint.

- Alternative Treatments: Some patients find relief through acupuncture or other alternative therapies, but these should be discussed with your healthcare provider to ensure they complement your recovery plan.

3. Injections: The use of high-concentration glucose (also known as prolotherapy) is a treatment that some practitioners use to promote healing in injured tissues. However, the efficacy of such treatments can vary, and it’s essential to discuss these options with your orthopedic surgeon or a pain management specialist.


Conclusion
In summary, understanding the nature of your ACL injury is vital for effective recovery. Given that you have a complete tear, surgical reconstruction is likely the best option to restore knee stability and function. Pain management will be an integral part of your recovery, and working closely with your healthcare team will help you navigate this process effectively. Be sure to follow up with your orthopedic surgeon for personalized advice and to discuss any concerns about your pain or rehabilitation progress.
