ACL/PCL Injuries

Around 86% of all knee injuries are found to be ACL or anterior cruciate ligament tears, whereas PCL or posterior cruciate ligament injuries occurred around 7% in an observation by NIH. Adolescents and young people between 12 to 20 years of age are more prone to this injury. Patients should seek early diagnosis and proper treatment from expert orthopedic surgeons.” – National Institute of Health, Healthy Children

What are ACL or PCL Injuries?

A knee consists of four ligaments, which keep the stability and movement of the bones in the joint. Two of them are the anterior cruciate ligament and the posterior cruciate ligament (ACL and PCL). Any sudden change in movement or playing sports can cause injury to these ligaments. Most commonly a popping sound occurs at the time of the ligament tear. The PCL joins the bone of the shin to the rear of the thigh bone. 

Depending on how much the tear extends, these injuries are categorized as grade I, grade II, grade III, and grade IV. As some of the symptoms, a person would feel slightly uncomfortable or face severe instability. It also has long-term problems that may get worse with time. Thus, one person needs immediate ACL injury treatment to regain knee functionality.

Symptoms of ACL or PCL Injuries

ACL and PCL can affect knee stability. Both cause pain and swelling. Sometimes, the symptoms can be the same type but different in intensity. ACL injuries and pain are often major than PCL injuries. Also, ACL can cause complete avulsion in the ligament. There are some common symptoms of these injuries:

  • Pain: ACLs result in severe pain, which can get worse over time than PCL injuries.
  • Swelling: You can feel gradual pain in the ACL, and it takes 24 hours to be swollen. PCL swelling happens quickly.
  • Instability: Both injuries cause soreness and discomfort in the knee. Individuals may feel helpless and possibly fall or twist their knees.
  • Audible “popping” sound: An ACL tear usually produces a popping or cracking sound during the time of the injury.

PCL injuries are not as painful as ACLs. In PCL tears, you will feel quick swelling. These types of knee injuries hardly result in complete instability. Thus, you should get a proper diagnosis and suggestions from a professional about ACL injury treatment.

What are the Main Causes of ACL or PCL Injuries? The Risk Factors

The ACL can get injured when one stops, sits, or changes direction suddenly or turns around when playing. Also, you can injure them by jumping and landing while practicing acrobatics. Soccer, football, and basketball athletes mostly get these injuries. Occasionally, the ligament pulls a small part of the bone, and it is called an avulsion fracture. Also, sometimes, the fluid may build up in a ligament and weaken it.

Risk Factors for ACL Injuries

  1. Injury to the anterior cruciate ligament is more common in women than in men. Also, the smaller thigh bones hold the ligament closer to the other bones, which makes less space to move. 
  2. Landing with straight legs or with knees bending inward and rotating on the leg causes traction on the ACL.
  3. The lack of stronger hip and stomach muscles puts an extra load on the knees.
  4. When a person has strong front thigh muscles but small, weak back thigh muscles, these can pull the ACL.
  5. In some cases, the shoes stick more to the ground during the dry period. Not all ACL injuries result from a direct hit on the leg; many occur while falling or during some other sudden movements.

ACL injury treatment depending on grade treatment varies from physiotherapy, and exercises to Regenerative orthobiologics to hybrid ACL surgical repairs. Also, to prevent this ligament from pulling, one should train effectively, wear proper shoes, and maintain strong knee muscles.

Diagnosis of ACL or PCL Injuries

To diagnose the accuracy of an ACL or PCL injury, one must follow several procedures. The doctors start the assessments by checking the signs of inflammation, pain, tenderness, and limitations to movement. They compare the injured knee with the healthy knee to get the results. Doctors also take additional tests, such as:

  • X-rays to reduce the possibility of bone fractures.
  • Any damage to soft tissues is identified using ultrasound.
  • CT or MRI scans are used to get clear images of ligaments, cartilage, and other soft tissues.

The results of MRI are very accurate for checking ACL injuries. They help assess the injury’s extent and identify other cartilage glitches. An accurate diagnosis holds much importance in ACL injury treatment.

What is the best treatment for an ACL injury: ACL Injury Treatment

Almost every ligament injury has multiple grades defined by how deep the tear is. In case the tear is mild, it can heal on its own. In such cases, you can promote healing by using medicines for pain relief and inflammation. 

Moreover, the RICE method also helps heal ligament tears faster. If you have an ACL tear, then you can follow the RICE treatment by resting and not putting stress on the knee, followed by applying ice to manage pain. Moreover, compression and putting the leg in an elevated position help deal with inflammation and allow faster recovery. After the recovery, physical therapy helps strengthen the muscles further for improved support to the knee. 

However, if the tear is of a higher grade, then you must opt for other treatment options like regenerative intervention. In regenerative orthobiolgics intervention, orthobiologics are prepared to be injected into the affected area, which allows the recovery of even deeper ligament tears. But if your ligament has totally torn, then ligament reconstruction is the only option, which is a surgical approach.

Recovery and Rehabilitation

For rehabilitation of ACL injuries, one should restore the motion, strength, and stability. Initial activities for ACL injury treatment are passive knee bends and small circular knee movements. Proprioceptive movements like balance and stability of a joint are vital for muscular-skeletal stability. Try to make your return to full activities under the supervision of a physical therapist.

  • Concentrate on knee extension and flexion in passive and active movements.
  • Use elevation, compression, and correct medicines.
  • Start walking weight-bearing by getting advice from your doctor.
  • Add proprioceptive movements to increase stability in the joints.
  • Gradually move between activities by listening to your physiotherapist and adapting the pace you move in between them.

Prevention Tips for ACL or PCL Injury

The ACL is vital for your knee stability which also acts as a stabilizer when the leg is moving. The patella links the femur and the tibia and prevents lateral and longwise movements. Ankle ligament injury can occur without any involvement of contact. Try to prevent it early if you are an athlete or an active person. Below are simple tips to reduce the risk of ACL injuries:

  • Knee-supporting muscles will build the quads and hamstrings.
  • Strengthen your weaker leg muscles to prevent any pull or strain.
  • Do not tear ligaments in their stretched position, and always perform gentle stretching in their treatment.
  • Stay hydrated; always try to keep the tissues flexible by drinking water.
  • Do strength and flexibility exercises all year round.
  • Gently touch the ground with knees bent to spare the ligaments.

These tips reduce the chances of getting an injury and keep your knees healthy. One should immediately consult experts to have ACL injury treatments if there is any kind of pain.

When to See a Doctor?

Some of the signs if you suffer an ACL injury are a pop in your knee or even a snapping sound. You may find that it is difficult for you to stand or walk, and you may feel more like your knee is going to give way. While some experience pain, others may experience a tingling sensation. One should get medical attention if they have wrecked their knee.

Conclusion

ACL and PCL can hamper your knee with pain, swelling, and lesser mobility of the knee joint. Seek medical help as early as possible for proper ACL injury treatment to keep away the warning signs. For the best care for your knee joints and ligaments, contact Axis Clinics.

Frequently Asked Questions

If your additional ligaments are torn or if your knees are not stable till now after physical therapy, then you may need surgery. But before that, always consult with your doctor about your age and physical condition.

Rotational instability is the prime symptom of the anterior cruciate ligament. You may walk, or run, in a straight line after an ACL injury, but you can fall when you want to move in a direction. A PCL injury can also cause mild instability in your knees.

You have to push down on the knee displacement from its normal position. If you detect too much movement in your joint, it can be a PCL tear. It is always recommended to consult experts at Axis Clinics for better diagnosis.
