Does Grade 1 Acl Tear Require Surgery
A grade 1 ACL sprain occurs when your ACL is overstretched, but not torn. If your knee is still stable, you likely have a grade 1 injury and may not need surgery. A grade 2 ACL sprain is a partial tear. If you have a grade two sprain, your ligament is damaged and youll likely experiences some instability.
What Are The Symptoms Of A Cruciate Ligament Injury
Often, a cruciate ligament injury does not cause pain. Instead, the person may hear a popping sound as the injury occurs, followed by the leg buckling when trying to stand on it, and swelling. However, each individual may experience symptoms differently.
The symptoms of a cruciate ligament injury may resemble other conditions or medical problems. Always consult your doctor for a diagnosis.
Looking At Fluid In The Knee
If your knee looks red, feels warm to the touch, or is very swollen, a knee joint aspiration may be done. This involves removing fluid from the knee joint with a needle. It is done to:
- Help relieve pain and pressure. This may make the physical exam easier and make you more comfortable.
- Check joint fluid for possible infection or inflammation.
- Look for blood, which may mean there is a tear.
- Look for drops of fat, which may mean there is a broken bone.
Local anesthetic may be injected to reduce pain and make the knee easier to examine.

Hearing An Audible Pop

People who suffer an ACL tear usually report hearing a “pop” at the time of the injury. Most people are surprised at how loud this can be, and many bystanders have heard this from the sideline of a football or soccer game. Even if you don’t hear the pop, usually people will feel the sudden shift in the joint.

Causes Of Anterior Cruciate Ligament Injury
Most anterior cruciate ligament injuries happen during sports, especially football, basketball and skiing. Women are more likely to injure their ACL than men. An ACL injury may happen if you:
- twist your knee, particularly when your foot is on the ground for example, you land from a jump and twist in the opposite direction
- quickly change direction when running or walking
- slow down or stop suddenly when running
- over extend your knee joint
If youre playing contact sports, you can also injure your ACL if you have a direct blow to your knee from a collision with another player.

Clinical Assessment Tools To Identify Atrisk Athletes
Development of clinical assessment tools to identify athletes at risk for ACL injury would aid clinicians to target the populations that will benefit most from intervention. Although predictors of ACL injury that are potentially modifiable like measures of high knee abduction moment during landing tasks, these measurements utilized expensive measurement tools and laborâintensive data collection and reduction techniques to identify important biomechanical risk factors.
Identification of athletes with high knee abduction moments is possible with less expensive equipment and time. These clinical prediction tools show moderate to high interârater reliability and have continued to simplify and optimize the screening tools to include a calibrated physician’s scale, a standard measuring tape, standard camcorder, Image software, and an isokinetic dynamometer. These optimized measures predict high knee abduction moments status with 84% sensitivity and 67% specificity. A clinicianâfriendly nomogram tool demonstrates over 75% prediction accuracy for identification of high knee abduction moments in individual athletes. Creation of clinicianâfriendly, inexpensive techniques to identify and subsequently enroll athletes into appropriate injury prevention programs may help reduce ACL injuries in athletes.

What Is The Recover Time After Torn Acl Surgery
Rehabilitation and return to normal function after surgical repair of an ACL tear can take six to nine months. There needs to be a balance between trying to do too much work in physical therapy returning strength and range of motion and doing too little. Being too aggressive can damage the surgical repair and cause the ligament to fail again. Too little work lengthens the time to return to normal activities.
Whats Worse Acl Or Mcl Tear
With an MCL tear, the recovery process may take up to eight weeks or more with rehabilitation. On the other hand, an ACL tear will most likely require surgery and at least six months or more of rehabilitation. A torn ACL or MCL is a serious injury that should be assessed and treated by an orthopedic surgeon.

Chronic Inside Knee Pain After Acl Surgery
My patient this past week had an ACL reconstruction surgery years ago. Her ACL graft is mostly gone at this point, which is not uncommon. More importantly, she experiences deep pain right at the tibial tunnel site. Thats where they drilled the hole to create the tunnel to anchor the ACL graft. So she has pain after ACL surgery.
As the video above shows, the patients pes anserine tendon was destroyed by the surgeons drill. This is an important tendon of three thigh muscles . This is like a guy rope system for the inside knee, so damaging this tendon will change how the knee works.
What can I do to help? Our plan is to use precise ultrasound guidance to inject her own bone marrow stem cells into the damaged area of the pes tendon. Hopefully, this will cause enough healing so that her pain after ACL surgery at this spot will go away.
How Can You Prevent Acl Injuries
The best way to prevent ACL injuries is to stretch and strengthen the leg muscles, especially the front and back muscles of the thigh .
Here are other things you can do that may help prevent ACL injuries:
- Avoid wearing shoes with cleats in contact sports.
- Avoid wearing high-heeled shoes.
- Avoid sports that involve lots of twisting and contact.

What Is The Treatment
A medical professional may be able to determine the severity of your injury with a physical exam; in some cases you need an X-ray or MRI to confirm the diagnosis.
Once diagnosed, patients will almost always have to receive surgery. For older athletes, or those who are relatively inactive, a brace and physical therapy may be enough to heal the injury.
In almost every other case, however, a minimally invasive surgery is required to reconstruct the ligament. Post-surgery recovery time varies from one athlete to the next, but most people are able to return to their sport within six to nine months, according to Health.UCSD.edu.
ACL injuries are very common, and almost always result in a complete tear of the ligament. Work to prevent this injury by keeping your lower body strong with jump squats, lunges and landing practice.
Unfortunately, even a strong lower body can’t prevent an ACL tear. Knowing the symptoms ensures you can seek medical attention immediately, and ultimately results in a quick return to your sport.
The reality is that there is no quick fix to an ACL injury, however there is a solution to ease pain and speed up recovery: wearing an ACL brace.
Blowing Out Your Knee: Acl Tear And Pain Management

Charles H. Brown, MS Pharm, RPh, CACPProfessor Emeritus of Clinical PharmacyPurdue University College of PharmacyWest Lafayette, Indiana

One of the most feared sports and work injuries is a tear of the anterior cruciate ligament , which has ended or derailed the careers of numerous high-profile athletes. A torn ACL is very painful and can debilitate a person for several months and perhaps for life, although recovery for some is possible. In his book, professional football player Drew Brees describes blowing out his knee as a high school quarterback in 1995.1 However, following knee reconstruction surgery and rehabilitation, he went on to play for Purdue University and later the New Orleans Saints, who won Super Bowl XLIV in 2010. Other high-profile athletes who have sustained ACL tears include football quarterback Tom Brady, golfer Tiger Woods, and soccer player Frankie Hejduk.2;
An ACL tear is one of the most common sports-related injuries, and its rehabilitative course may last 6 to 9 months.3 ACL tears may also occur during rough play, motor vehicle collisions, falls, and work-related injuries. About 80% of sports-related ACL tears are noncontact injuries.2 Most often, ACL tears occur when an athlete pivots or lands from a jump. The knee gives out from under the athlete when the ACL is torn. In addition to the ACL, other ligaments and the meniscus cartilage may also be damaged.;

How Do Acl Injuries Happen
There are two common ways that the ACL is injured:
- In the first situation, the individual may be running and quickly cut or pivot. This results in excessive stress and subsequent sprain of the ligament.
- The second scenario involves someone or something falling onto the knee while it is fixed in place. This excessive amount of force results in a strain on the ligament.
What Is An Acl Tear
The anterior cruciate ligament, or ACL, is located in the middle of your knee and helps stabilize the joint. ACL injuries commonly occur while playing sports that involve sudden stops or changes in direction, such as basketball, soccer, tennis, or football.
Injuries can range from overextending the ligament to a full tear. A mild injury may strain the ligament but keep it intact. Moderate to severe injuries can cause a partial or full tear of the ligament. You will likely hear a popping noise if that type of injury occurs. You may experience swelling or be unable to put weight on the injured knee.

Treatment And Recovery For Acl Vs Mcl Tears
Immediately after injuring your knee, apply ice to the area, use a compression garment to stabilize the joint, and prop up your knee to elevate it until you can get medical treatment.
Dr. Heiden will evaluate the condition of your knee and guide you in rehabilitation. He will provide a stabilizing brace and may recommend crutches during the initial healing process.
Moderate to severe ACL tears can require surgery to resolve. In most cases, a graft is used to replace the torn part of the ligament. Recovery can take six months or more depending on the severity of the injury. Dr. Heiden will help you determine if surgery is necessary. An MCL tear rarely needs surgery and typically heals after approximately eight weeks of focused rehab. Heiden Orthopedics treats a range of ligament injuries, including ACL and MCL tears. Learn more about the knee anatomy and procedures.
Diagnosing An Acl Injury
A doctor can usually accurately diagnose an ACL knee injury by carrying out a clinical examination. The most common tests used are the Pivot Shift, Anterior Drawer and Lachmans Tests.
The video here from the American Academy of Orthopedic Surgeons shows a positive Lachmans test i.e. an ACL rupture.Diagnosis of ACL tears is often confirmed with an MRI which will also show if any other structures in the knee have been damaged as well.

What Happens During Surgery For A Torn Acl
ACL reconstruction surgery uses a graft to reconstruct the ACL. The graft can be a tendon, with or without bones attaching to it, from the patient’s own body or from someone else who donated the tendon .
ACL repair surgery is usually done arthroscopically. This type of surgery is done using a tiny camera and small instruments that are inserted through small incisions .
Recovery from ACL surgery can take 612 months. A person may use crutches and a leg brace after surgery, and might need a knee brace after that.
Physical therapy is important to help the knee heal. PT helps to:
- improve range of motion and flexibility
- regain strength in the knee, thigh, and shin muscles
- reduce pain and swelling
- improve balance
How Is An Acl Tear Diagnosed
In order to determine the cause of your symptoms and the extent of the injury, your doctor will ask you questions and perform a physical examination. X-rays are helpful in viewing the bony anatomy of the knee and can confirm or eliminate a diagnosis.
After your doctor has conducted the examination, he or she may recommend that you undergo more diagnostic tests, such as an MRI scan. An MRI allows your specialist to clearly see the muscles, tendons, and ligaments of the knee. This information helps him or her formulate a treatment plan tailored to your needs.

The Damage Done By Acl Surgery
Most people believe that when theyre getting a body part replaced like an ACL that the doctor merely switches out the part like a new tire on a car. However, thats not close to accurate. The surgery to replace the ACL will do predictable damage to the knee. This damage can lead to pain after ACL surgery.
For example, we know that the ACL reconstruction surgery itself acts as a second hit to the knee cartilage . Meaning the first cartilage damage event comes with the injury and the second comes after the doctor drills the tunnels to place the ACL graft. Meaning, based on recent research, the act of performing an ACL surgery may be further damaging the cartilage. This likely explains why, despite stabilizing the knee, ACL surgery doesnt prevent or delay the onset of knee arthritis . Obviously, the early onset of knee arthritis could be one cause of pain after ACL surgery.
Knee Pain After Acl Surgery

Do you still have knee pain even though you had an ACL surgery to correct it? Its one of the most frustrating things that I hear from people and they come in and they said, I had an ACL surgery and Ive really aggravated it. I dont know if Ive messed up the surgery.

How Can We Prevent Another Acl Tear
Having an ACL tear puts someone at higher risk for another one. Training programs may help your child avoid another ACL tear. These focus on neuromuscular training . NMT teaches movement patterns that lower the risk of injury, especially while jumping, landing, and changing direction. NMT programs include stretching, plyometrics , and balance training.
Ask your care team if an NMT program is right for your child.
When Should You Call Your Doctor
- You have severe pain in your knee.
- Your knee appears to be deformed.
- You have signs of damage to the nerves or blood vessels. Signs include numbness, tingling, a “pins-and-needles” sensation below the injury, an inability to move your leg below the injury, pale or bluish skin, or your leg feels cold.
- You have severe swelling in your knee right after the injury.
- Your knee starts to swell within 2 hours of the injury.
- You hear or feel a pop in your knee during an injury.
- Your knee won’t bear weight.
- You can’t straighten your leg completely.
- Your knee is unstable, buckles, or gives out.
- Your knee “locks” in one position.
- You’ve had an anterior cruciate ligament injury in the past, and you have reinjured your knee.
Before your appointment, don’t put weight on the injured knee. Use crutches if you need to. Apply ice and wrap your knee in an elastic bandage or neoprene sleeve. Rest and elevate the knee. Take a nonsteroidal anti-inflammatory drug, such as ibuprofen or naproxen , to reduce swelling.

Can Acl Injuries Be Prevented Or Avoided
The leading way to prevent injuries such as an ACL tear is to follow a training routine. A physical therapist, athletic trainer, or other sports medicine specialist can help you develop an exercise program that will help reduce your risk of injury. Such a program will usually include:
- Exercises that strengthen leg muscles
- Exercises that strengthen your core
- Techniques and proper knee position when jumping and landing
- Techniques for movements that can lead to injury, such as pivoting or cutting
There is no clear evidence that use of a knee brace prevents ACL injuries. There also is no proof that a knee brace helps more during treatment or physical therapy.
