Knee Swelling

What Swelling in the Knee Could Mean

Swelling of the knee, also known as water on the knee, is a condition in which fluid collects around the knee joint. Swelling can occur for a variety of reasons and affect patients of any age.

Some swelling can be treated with over-the-counter medicines, but persistent and continuous swelling might result in tissue damage, bone softening, and cartilage deterioration.

At-Home Treatment

Over-the-counter medicines will assist relieve pain for individuals with a history of osteoarthritis and swelling following physical activity, such as exercise or running. During and after activity, the patient may apply compression sleeves to reduce the inflammation. Ice is another method to decrease swelling at home by using R I C E: Rest, Ice, Compression, and Elevation. But if swelling persists then seeing your physician is critical!

When Should You See A Doctor?

The short answer is that, when knee swelling is accompanied by continual discomfort and other symptoms, like pain or knee locking, it is best to visit a doctor. This is also advised when knee swelling does not go down with the aid of OTC medications or continues to be swollen for long(er) periods of time. But as a rule, anytime there is swelling in the knee, this is a warning sign your body is telling you.  The body is warning you that there is something significantly wrong with the knee and needs to be diagnosed and treated.  Swelling can be a sign of damaged cartilage, bone, meniscus, or tendon and if it isn’t identified can lead to more permanent damage. 

ACL Tears

The Anterior Cruciate Ligament (ACL) is one of four major ligaments in the knee. It is an important stabilizer of the knee and prevents the shin bone (tibia) from sliding in front of the thigh bone (femur). The ACL is susceptible to injury. It is most likely to be injured during activity or by impact. A torn ACL is a common injury for athletes at all levels, but it is most common for people who are active or who experience impact injuries to the knee. ACL injuries can happen to anyone of any age, condition, or ability, and it can be injured in many ways. Examples include abruptly changing direction, slowing down while running, landing incorrectly, or getting struck by someone or some object.

Baker’s Cyst

A Baker’s cyst can cause knee pain. A Baker cyst is swelling caused by fluid from the knee joint protruding to the back of the knee. They are NOT a true cyst since it has communication with the synovial sac. They typically arise from degenerative changes or injury to the articular cartilage (arthritis) or meniscus. At the Centeno-Schultz Clinic, we believe that baker’s Cysts are simply a barometer of the health of the knee joint. In a healthy knee, there are absent whereas with injury and degenerative changes they are common. They arise between the tendons of the medial head…

Chondromalacia

Chondromalacia is the knee usually causes pain, typically around the kneecap or deep in the kneecap. You can also have some grinding sensations or crepitus which are sounds and noises coming from around the knee with certain motions. Typically, pain and grinding sensations are worse with bending the knee, especially for prolonged periods of time, kneeling on the knee, walking downstairs, or running downhill. Standing after prolonged sitting or an immobility period where the knee is bent can cause some discomfort as well. Some people may experience swelling, others may experience locking or catching in the knee, feeling the knee wants to give out, or a feeling of weakness….

Hamstrings Tendinopathy

Your hamstrings are the thick muscles in the back of your thigh that are responsible for the movement of your hip, thigh, and knee. The hamstrings are made of three distinct muscles: Semitendinosus, Semimembranosus, and Biceps Femoris. What is Hamstrings Tendinopathy? Tendons are thick pieces of connective tissue that connect muscle to bone. They function to transfer the force generated by muscle contraction into movement. Hamstring tendinopathy, also known as a “calf strain,” is an injury to the affected tendon. It usually occurs when you bend your knee or extend your leg, putting too much force on the hamstring tendon….

Knee Arthritis

In the human body, a joint is simply where 2 ends of bone come together. At the ends of these bones, there is a thick substance called “Hyaline Cartilage” that lines the ends. Hyaline cartilage is extremely slippery which allows the two ends of the bone to slide on top of each other. Then there is a capsule that connects the two ends filled with “synovial fluid” that acts as a further lubricant to make it more slippery! Arthritis in the knee is defined by loss of the hyaline cartilage plus other changes that happen to the bone such as additional bone being laid down (bone spurs/osteophytes). The cartilage layer is worn down to the point of exposing the underlying bone they cover…

Knee Instability

Knee instability is a condition that results when the knee joint is unstable and does not move or function normally. This can cause the knee to feel like it is going to give out or buckle. Knee instability can be caused by a variety of factors, including trauma or injury to the knee, ligament injury, arthritis or other degenerative diseases of the knee, weakness or instability of the muscles around the knee, muscle atrophy, injury to another joint in the body creates an imbalance. Knee stability, and stability in general, is very important. Lack of knee stability can lead to more problems over time, such as pain and arthritis…

LCL Sprain

What is an LCL Sprain? A strain or tear to the lateral collateral ligament (LCL) is known as an LCL injury. The LCL is a band of tissue that runs along the outer side of your knee. It aids in keeping the bones together while you walk, ensuring that your knee joint remains stable. How you feel and what type of treatment you’ll require depends on how severely your LCL has been stretched or torn. If it’s only a minor sprain, self-care at home might help. However, if it’s a significant tear or sprain, you may need physical therapy, an injection-based procedure, or surgery….

MCL Sprain

The medial collateral ligament AKA MCL is a thick, strong band of connective tissue on the inside portion of your knee. It connects the top part of the tibia (shin) to the bottom part of the femur (thigh). This is a vital ligament that works along the lateral collateral ligament (LCL), anterior cruciate ligament (ACL), and posterior cruciate ligament (PCL) to bring stability, structure, and movement to the knee. The MCL provides support and stability for the inside (medial) aspect of the knee. MCL sprains are a common injury in sports such as football, hockey, and skiing. The ligament can…

Meniscus Tears

The meniscus is a c-shaped piece of cartilage in the knee that functions as an important shock absorber. It is sandwiched between the thigh and shin bone. There are two menisci per knee. One on the inside portion of the knee (medial) one on the outside aspect (lateral). The knee meniscus is susceptible to injury. The most common injury is a tear in the meniscus. Not all meniscus tears however cause pain. When symptomatic a meniscus tear can cause pain, swelling, and restriction in range of motion. Tears in the knee meniscus can arise from trauma or degeneration. There are many different types of meniscus tears based upon locations….

Patellar Tendon Tear

The Patellar tendon is the thick connective tissue that starts at the base of the kneecap (Patella) and extends down to the shin.  The is an extension of the Quadriceps tendon (1).  The Quadricep is the large thick muscle that is often referred to as our thigh. The Patellar tendon works together with the Quadriceps muscle to straighten (extend) the knee. It is easy to touch your Patellar tendon as it is immediately below the knee cap. There are many different causes of Patellar tendon tears.  Patellar tendon tears are a common sport injury but can also occur from overuse or a motor vehicle injury…

Patellofemoral Syndrome

The kneecap is also known as the patella. The thigh bone is the femur. The patellofemoral joint is formed by the kneecap and the grooved surface of the thigh bone. The patella slides up and down in a grooved track in the femur. The groove is more specifically called the trochlear groove. Like a train that travels on a track, under ideal conditions the patella tracks up and down in the trochlear groove. What is Patellofemoral Syndrome? Patellofemoral syndrome is a medical condition characterized by discomfort in the front of the knee and around the patella. Patellofemoral syndrome may also be known as “jumper’s knee” or “runner’s knee.”…

PCL Sprain

The Posterior Cruciate Ligament is one of the paired ligaments in the middle of the knee. It is made up of 2 separate bundles: The two bundles of the PCL, and the ALB (anterior lateral bundle), and the PMB (posterior medial bundle), function synergistically to provide stability. The PCL functions as one of the main stabilizers of the knee joint and serves primarily to resist excessive posterior translation of the tibia relative to the femur. The PCL also acts as a secondary stabilizer of the knee preventing excessive rotation specifically between 90° and 120° of knee flexion. A PCL sprain happens when force is applied beyond…
