Torn Acl Symptoms And Signs
With an acute injury, the patient often describes that they heard a loud pop and then developed intense pain in the knee. The pain makes walking or weight-bearing very difficult. The knee joint will begin to swell within a few hours because of bleeding within the joint, making it difficult to straighten the knee.
If left untreated, the knee will feel unstable and the patient may complain of recurrent pain and swelling and giving way, especially when walking on uneven ground or climbing up or down steps.
The knee is one of the most commonly injured parts of the body. Sports, falls, and motor-vehicle accidents account for the vast majority of knee pain and injuries to the knee.
The different types of common knee injuries to the knee are defined by the affected anatomy of the knee and the mechanism by which it’s injured.
Knee sprains are injuries to the ligaments that hold the knee together. There are multiple ligaments that stabilize the knee and keep it in alignment. The anterior cruciate ligament and the posterior cruciate ligament stabilize the knee in movement from front to back and cross each other in the middle of the knee joint. The medial collateral ligament and lateral collateral ligament stabilize the knee so that the bones do not slide from side to side.
Ligament sprains are graded by the amount of stretching or tearing of the ligament fibers and how much instability it causes as follows:

Knee Injury Risk Factors
- Sports – Many sports require movements that place added stress on your knees Skiing, for example, can lead to stress on the knees due to the restricted movement of your feet. Another example is basketball where players have to pivot and jump. These sudden and repetitive movements can put stress on the knees.
- Previously injured knee – If youve already hurt your knee once, then it may not be as strong as it was before. Unfortunately, this could make it easier for you to injure your knee again.
- Excessive weight – If you put on a lot of weight, your bones have more work to do to support that mass. For those who are very overweight, even ordinary daily activities can cause wear and tear on the knees.
- Weak muscles – A lack of strength and flexibility in your muscles can also contribute to knee injuries. Strong muscles protect bones and joints. Aside from this, they also make you very stable and balanced, thereby decreasing the risk of falls.
- Gender – Women are more likely to develop knee injuries simply because of how their bodies are built, for example, the way their hip bone is attached to the thigh bone and the fact that they carry greater mass on the lower body.

Why Is My Knee Injury Not Healing
If you notice your knee injury isnt healing, it could be because you misjudged the severity or you simply didnt give it enough time and rest.

Healing A Swollen Knee And Leg
Q1. I fell on the sidewalk about a month ago and skinned and bruised my knee. I went home, iced my knee, and put Bactine and Neosporin on it. I had a lot of pain in my knee. I noticed there is swelling around my kneecap. It looks like fluid inside. What should I do?
Angela, New Jersey
Following trauma to any part of our bodies, it is very natural to bleed. When the bleeding occurs into the skin, we develop what is referred to as a hematoma, a collection of blood in the soft tissue. Hematomas will usually heal over time all that is necessary to help with the healing is application of ice at first, followed by heat. Bleeding can occur into other parts of our body as well.
I would strongly recommend you visit your physician so that a determination can be made as to whether the fluid is in the bursa which is less serious or in the joint, which would be of greater concern. Once the diagnosis is made, appropriate treatment can be initiated. Warning signs of fluid in your joint would include a decrease in the knees range of motion, as well as fever or increased pain.
Q2. Sometimes my knee is swollen and painful. What could be the cause of my sore knee?

Medical Therapies For Knee Sprains Strains & Tears
Any type of knee injury considered to be mild, such as a sprain, typically does not cause significant discomfort. Your doctor may recommend resting the affected area by using a knee brace and modifying your daily activities for a short time. This helps you to avoid added stress on the injured area. Over time, injuries such as mild sprains and strains, as well as mild meniscal tears, may heal on their own. Your doctor may recommend medications or arthrocentesis to relieve knee pain.
NYU Langone doctors can advise you on how best to go about your daily activities as you heal without exacerbating the injury to the muscle, tendon, or ligament.
Soft Tissue Knee Injury Causes
The causes of soft tissue knee injuries fall into the following categories:
- Overuse injuries These injuries are a result of repeated strenuous activity over time, allowing the soft tissues no time to heal properly.
- Acute injuries These injuries are a result of sudden trauma, such as a fall or blow to the knee.

How Can I Tell If My Knee Injury Is Serious
There are several ways to tell if your knee injury needs serious medical attention:
- You heard a popping sound right after an incident – This sound is created by ligament tears or dislocated kneecap.
- Your knee looks deformed – This is a symptom of a fractured or dislocated kneecap.
- You cant straighten your leg or put weight on it – There may be a fracture on your kneecap or tear in the tendon.
- Your knees are weaker than usual – If they keep buckling underneath the usual amount of weight you carry, then its possible that you may have an ACL tear or some other form of ligament injury.
- You have a greater range of motion – Are your legs bending in a different way than usual? This may seem like a good thing but this can also indicate that there is a dislocation or tear around your knee.
Complications Of A Swollen Knee
You may develop a Bakers cyst. This is when joint fluid leaks out into the back of the knee and causes pain and swelling. Treatment usually involves compression and applying ice packs. However, if your swelling is severe, you may need to have the fluid removed using a fine needle.
You may lose muscle mass, especially in your thigh muscles. This is because fluid in your swollen knee can prevent your thigh muscles from working properly over time this causes them to weaken and deteriorate.
Most bruises, also known as contusions, are mild and heal on their own. However, more severe contusions can damage muscle tissue or bone, which may take longer to heal.
According to the American Academy of Orthopedic Surgeons, rest, ice, compression, and elevation may help reduce symptoms and aid healing.
This article explores how bruises form, how to treat them, and how to tell if a bruise could be a sign of a more severe injury, such as a fracture.
A bruise or contusion forms when small blood vessels under the skin break, but the skin remains intact. Blood leaks out of these broken capillaries into the surrounding soft tissues, which causes discoloration.
There are three types of bruises:
- subcutaneous, which occur just under the skins surface
- intramuscular, occurring within the underlying muscle
- bone bruises, which are an injury to the bone
A knee bruise may also trigger symptoms such as:

Can Runners Knee Cause Permanent Damage
There are several things that can cause a flare-up of runners knee. One of the most common causes is overuse from bending your knee repeatedly or doing too much high-stress exercise. Lunges and plyometrics are both high-stress exercises that could cause runners knee. This type of overuse causes irritation to the tissues in and around the kneecap.
Falling down on your knee or taking a direct blow to the knee is another possible cause. Some less common medical conditions may cause knee pain, too. Chondromalacia patella, which happens when the cartilage under the kneecap breaks down, is much less common but can be very painful. Even problems with the feet, thigh muscles, or bones in your hips and ankles can cause runners knee. Heres how runners knee is diagnosed and treated, and how you can prevent a flare-up in the future. How long does it take for runners knee to heal? The cure of a runners knee may take up to 6 weeks.
Whats On The Horizon For Acl Treatment
According to McCarty, the most exciting new development is bridge-enhanced anterior cruciate ligament restoration, also known as the BEAR implant.
Unlike ACL reconstruction which relies on a graft from the patient or donor BEAR can heal a torn ligament. The procedure uses a an implant containing bovine collagen and the patients own blood to fill the gap between the torn ends of the ACL and promote healing.
Traditionally, the ACL does not heal itself, McCarty said. There are a lot of factors that dont allow for it.
These include impaired blood flow to the ligament after an injury and cells inside the synovial fluid in the knee that prevents healing.
Previous attempts to heal an ACL tear have all ended in failure. Now theres the potential that you can heal your own body, McCarty said.
Pioneered by Dr. Martha Murray, orthopedic surgeon-in-chief at Boston Childrens Hospital, the BEAR procedure has shown such promising early results that the FDA authorized its marketing in late 2020.
BEAR is now being studied at sites across the nation, including UCHealth. Select patients will be randomized to receive either BEAR or traditional ACL reconstruction without knowing which surgery was performed.
If BEAR proves to be comparable or superior to grafts, it could become the new gold standard for ACL treatment. But that will require years of study and analysis.
