When To Consider Knee Drainage
Knee swelling can be a painful, functionally debilitating condition and should not be ignored. Many cases of knee swelling can be resolved with rest, ice, physical therapy, and anti-inflammatory medication. However, if the swelling begins to restrict movement or becomes increasingly painful, you may be eligible for knee drainage.
Knee drainage can both diagnose the source of swelling and provide effective pain relief and improved mobility. Moreover, it is a simple in-office procedure requiring very little downtime. If you are experiencing pain and swelling in your knee, drainage may be the most effective option to get you back to performing your daily activities pain-free.

What Is Knee Joint Aspiration And Injection
Joint aspiration and injection refer to the placement of a needle into a joint cavity to remove fluid for analysis or study, and to inject medicine for pain relief or treatment of a disease . Sometimes the doctor may only remove some of the joint fluid to establish a diagnosis for the collection of fluid. In other cases, such as in patients with chronic osteoarthritis, the doctor may only inject medicine to provide pain relief.
Knee Infection After Surgery
Knee replacement surgery is a common surgery that doesnt present complications for most people. In less than 1 percent of joint replacement surgeries, an infection occurs around the area of the artificial implant. However, as joint replacements are on the rise, so is the rate of infection.
Since artificial joints are made of metal and plastic, they dont have any sort of immune capability to fight off harmful bacteria. Artificial joints can become infected at the time of your surgery, or even years after your surgery.
Surgeries performed to repair torn cartilage or tendons can also introduce bacteria to the knee joint. ACL repair and meniscus repair are among the common knee surgeries that can result in an infection.

PRICE Method – If knee trauma or injury is the cause of the knee fluid, then your doctor may recommend that you use the PRICE method of Protection, Rest, Ice, Compression and Elevation. The combination of these is often used as first aid treatment to minimize fluid in the knee after a traumatic injury.
Medications – There are different types of medications that may be used to treat the excess of knee fluid, depending on the cause of the issue. For example:
- Over-the-counter medications – Pain medications such as ibuprofen or aspirin may be used to help reduce inflammation

How Is The Procedure Performed
Your doctor will wash the skin over the joint with an antibacterial solution and then select the easiest and safest method of entry into the joint. Although the skin over the joint can be numbed, the injection of the numbing medicine often hurts more than the needle insertion itself. The needle is inserted carefully into the joint, and fluid may be withdrawn. Without having to perform an additional needle-stick, the syringe holding the fluid can be removed, and a syringe containing the medicine is placed on the needle. The medicine is inserted quickly, and the needle is removed.

- Gout caused by too much uric acid in your blood
- Infectious arthritis caused by an infection of a joint that leads to swelling
- Juvenile arthritis occurs in people aged up to 16 years
- Osteoarthritis the most common form of arthritis caused by break-down of cartilage in the joints
- Reactive arthritis usually occurs after an infection of your genitals or urinary tract and becomes chronic this is not common
- Rheumatoid arthritis your immune system mistakenly attacks your joints
If your doctor thinks your swollen knee could be caused by arthritis, they will ask you about any other symptoms and your medical history. They may refer you for further investigations, such as blood tests or an X-ray.

Is There Anything Else I Need To Know About A Synovial Fluid Analysis
Arthrocentesis, the procedure used to do a synovial fluid analysis, may also be done to remove excess fluid from a joint. Normally, there is only a small amount of synovial fluid between the joints. If you have a joint problem, extra fluid can build up, causing pain, stiffness, and inflammation. This procedure can help relieve pain and other symptoms.
Arthrocentesis Of The Knee
The knee and connecting suprapatellar pouch can be punctured while the patient is supine and the knee is extended. The needle, 18- or 20-gauge, can be inserted anteromedially, under the cephalad half or third of the patella. Alternatively, the needle can be inserted laterally, just under the cephalad edge of the patella .

What Is The Purpose Of Joint Aspiration And When Is It Performed
Joint aspiration can be both used for diagnosis and medical treatment of arthritis of a joint. Joint aspiration is used to obtain fluid from the patient’s joint for examination in the laboratory. Analysis of joint fluid can help the physician to define causes of joint swelling or arthritis, such as infection, gout arthritis, and rheumatoid disease. Fluid from the joint can be tested for white cell count, crystals, protein, glucose, as well as cultured to detect infection. Each of these laboratory parameters can be helpful in defining the cause of a particular form of arthritis, particularly in distinguishing inflammatory from non-inflammatory forms of arthritis. The result can be key to identifying various potential rheumatology diseases and musculoskeletal conditions.
Joint aspiration can also be a helpful treatment in relieving joint swelling and pain. Removal of synovial fluid from the joint that is inflamed can also remove the white blood cells within that are sources of enzymes that can be destructive to the joint. This treatment can more rapidly restore the health of the joint. Bursa aspiration procedure and indications for bursitis are analogous to joint aspiration for arthritis, except the bursa is the target instead of the joint . The result and analysis of the fluid is similarly evaluated for various diseases and conditions in the laboratory.
