Swelling of the Knee

By  aenriquez  published  February 20, 2020

A common complaint among knee injuries is a condition frequently called water on the knee or sometimes, simply, swollen knee. A doctor might refer to this as an effusion of the knee, which indicates the movement of fluid.

There are many causes for water on the knee, and it will take an examination and possibly some laboratory analysis of the fluid to figure out the underlying cause of the effusion. The first noticeable symptoms, however, include a swollen, puffy, stiff knee. It is likely to be painful. In addition, the swollen area could be soft and pliable, moving the way a water balloon feels when you poke at it.

Causes

There are many possible causes for water on the knee. There could be an underlying disease present. Your knee could be swollen from acute trauma, such as a sports injury involving a collision or an over-stretching of a ligament. Over-use could be the problem. This implies long-term use of the knee, often in a repetitive fashion, that has worn down some of the joint’s cartilage. A bone could be fractured or broken. An infection could have set in. Various diseases could also result in water on the knee.

Common Diseases

The most common knee diseases include osteoarthritis, gout, pseudogout, blood or bone infections, tumors, cysts, or bursitis.

Risk Factors

There are risk factors involved in knee conditions, including age – the older we get, the more susceptible we get to many conditions – lifestyle, especially when involved in high-stress sports, and obesity. The more overweight you are, the more likely you are to injury your knees or have cartilage wear down over time.

Prevention

If you can avoid getting old, that would help. Unfortunately, no one has figured that out yet. However, you can strengthen your leg muscles to give more support to your knee when you need it. You can also try losing weight to take some stress off of your knees.

Diagnosis

Doctors will first interview the patient to see if there is an obvious lifestyle or family history factor to take into consideration. After this, the physician may order an X-ray, an ultra-sound or MRI imaging to be done to get a look at what is happening in your knee.

If imaging does not result in a firm diagnosis, the doctor may try a joint aspiration, also called an arthrocentesis procedure. This involves drawing some of the fluid out of the knee (with a syringe and a need), then sending the fluid to the laboratory to look, primarily, for the presence of bacteria, indicating an infection or crystals, indicating either gout or pseudogout.

Treatment

Treatment might begin with drawing fluid from the joint to reduce the stiffness and pain. In some cases, the fluid may not return, and the patient will not need further treatment. However, there’s a chance the fluid will return, as the cause of the fluid has not been addressed.


Treatment may also involve the use of antibiotics, pain, or anti-inflammatory medication or surgery. The surgery could include a minimally invasive arthroscopic procedure or a more complicated procedure. Knee replacement surgery is also a possibility, depending on the underlying condition and after serious discussions of alternative therapies.

Common Knee Injuries

Knee Injuries

Many people enjoy playing sports and participating in physical activity, whether playing for fun in the backyard or competitively on a sports tea. Sports participation is beneficial to your health, but there is always the risk of injury. The knee is very vulnerable to injury in sports and everyday life. Knee injuries can occur due to poor training practices, flawed techniques, improper equipment, or accidents.

The knee is a complex joint that serves as an integral component of healthy mobility, and when one experiences an injury, he or she often requires surgery and physical therapy. Our orthopedic specialists are skilled at diagnosing and treating these common knee injuries. We assess your knee, conduct testing and imaging to confirm the problem, and develop a comprehensive treatment plan.

Sprains and Strains

The most common types of knee injuries are sprains and strains. A sprain occurs when a ligament tears or stretches beyond normal points. A ligament is a band of connective tissue that attaches bone to bone, and sprains range from minor ligament tearing to severe severing. A strain is where a muscle or tendon stretch beyond normal, and this can also be minor or severe.

Shin Splint

A shin splint is pain along the tibia (shin bone). This pain is typically at the anterior (front) region of the lower leg, but it can also occur in the knee region. Shin splints often affect runners who run on hard surfaces. Contributing factors for shin splints are poor running shoes, lack of support, failing to warm up/stretch, and having flat feet.

Fractures

The knee bones include the femur, tibia, and patella. Small cracks in any of these bones can occur from repeated stress. A stress fracture occurs from repeated impact, such as jumping or running. A patella fracture can occur from a fall onto the kneecap region. A tibia plateau fracture occurs when sudden excessive pressure collapses the top region of the tibia bone.

Dislocations

A dislocation occurs when one bone of a joint comes out of alignment. Also known as luxation, excessive stretching, falling, and twisting injuries can lead to a dislocation. Dislocated bones may be able to be realigned by a doctor, but some of these injuries require surgery. The condition involves bones of the knee being dislodged partially or completely.

Anterior Cruciate Ligament Injury

The anterior cruciate ligament (ACL) is an important knee structure. Injuries of the ACL are not just problems for athletes. A partial or complete ACL tear can occur from a quick change of direction, or from a compressive pressure of landing improperly when jumping. Damage to the ACL can cause an unstable knee.

Posterior Cruciate Ligament Injury

Posterior cruciate ligament (PCL) injury occurs when the knee is in the bent position. This type of injury results usually in only a partial tear and injury of the PCL can occur from falls or car accidents. The PCL does not have good blood flow, so tears of this type have difficulty healing.

Meniscus Tears

The meniscus is a wedge-shaped cartilage that serves as a cushion between the femur and tibia bones of the knee joint. Twisting or squatting can result in a meniscus tear, which also occurs from normal degeneration as people age.

Patellofemoral Syndrome

When the underside of the patella becomes irritated and inflamed, patellofemoral syndrome occurs. This is related to the kneecap rubbing against the femoral condyle with extension and flexion (bending) of the knee. The inflammation can result in serious pain.
