Urgent Care for Knee Pain: When to Seek Medical Attention

Anatomy of the Knee Joint

The knee joint is the largest joint in your body and connects the thigh bone (femur) to the shinbone (tibia). The kneecap (also called the patella) sits on the front of the knee joint and helps protect the joint. The knee joint is also surrounded by ligaments, tendons, and muscles that provide stability and movement.

There are two main components to the knee joint: the femorotibial joint and the patellofemoral joint. The femorotibial joint is the hinge joint that allows for flexion and extension of the knee. The patellofemoral joint is the gliding joint between the kneecap and the femur that helps with knee movement.

How the Knee Joint Works and Moves

The knee joint works like a hinge, allowing for one-way flexion and extension of the lower leg. The joint is also capable of rotation and gliding movements. The knee joint is supported by several major ligaments, including the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL), and lateral collateral ligament (LCL).

There are also several supporting muscles attached to the knee, including the quadriceps, hamstrings, and calf muscles. These muscles work together to provide stability and movement to the knee joint.

Common Injuries and Conditions That Affect the Knee Joint

The knee joint is susceptible to a variety of injuries and conditions, as outlined by the Mayo Clinic. Some common knee joint injuries include:

• ACL tear: a tear in the anterior cruciate ligament, often caused by sudden stops or changes in direction
• Meniscus tear: a tear in the cartilage that cushions the knee joint, often caused by twisting or rotating the knee
• Patellar tendinitis: inflammation of the tendon that connects the kneecap to the shinbone, often caused by overuse or repetitive jumping
• Osteoarthritis: a degenerative joint disease that can cause pain and stiffness in the knee joint

In addition to these injuries and conditions, knee pain can also be caused by overuse, improper form during exercise, or underlying medical conditions such as gout or rheumatoid arthritis.

Common Causes of Knee Pain

If you are experiencing knee pain, understanding the symptoms of common causes can help you determine what kind of care you may need. Knee pain can be caused by a variety of factors, including injuries, arthritis, bursitis, tendinitis, and more. Below we list some of the most common causes of knee pain, as outlined by the Mayo Clinic and Johns Hopkins.

Knee injuries

Knee injuries are a leading cause of knee pain. Common knee injuries include sprains, strains, and fractures. These injuries can occur as a result of sports activities, accidents, or falls. Symptoms of knee injuries can include pain, swelling, and difficulty moving the knee.

Osteoarthritis of the knee

Osteoarthritis is a degenerative joint disease that can affect any joint, including the knee. According to the Mayo Clinic, this condition occurs when the cartilage in the knee joint wears down over time. This can happen from repetitive stress (walking or running a lot), genetics, aging, or being overweight. Symptoms of knee osteoarthritis include pain, stiffness, and swelling.

Rheumatoid arthritis

Rheumatoid arthritis is an autoimmune disorder that can cause knee pain. This condition occurs when the immune system attacks the joints, causing inflammation. Symptoms of rheumatoid arthritis can include pain, swelling, and stiffness.

Bursitis

According to the Mayo Clinic, bursitis is a condition that occurs when the bursae (small fluid-filled sacs that cushion the knee joint) become inflamed. Bursitis can be caused by frequent or prolonged pressure such as kneeling on hard surfaces, strenuous activities, direct trauma to the knee, or a bacterial infection. Symptoms of bursitis include pain and swelling.

Tendinitis

Tendinitis is a condition that occurs when the tendons that attach the muscles to the knee joint become inflamed. This can happen from repetitive stress on the knee (usually from sports) and can cause knee pain and stiffness.

Risk factors for knee pain

There are several factors that can increase your risk of developing a condition that causes knee pain, according to the CDC. These risk factors include age, obesity, and sports involvement. If you are experiencing knee pain, it is important to talk to your healthcare provider about any risk factors that may be contributing to your discomfort, and what you can do to help alleviate the stress on your knee.

Prevalence of knee pain in the population

Knee pain is a common condition that affects many people. According to the CDC, around 23% (or 1 in every 4) adults have arthritis of the joints. If you are experiencing knee pain, it is important to talk to your healthcare provider about your symptoms and treatment options. Ignoring knee pain can lead to irreversible damage, according to the Cleveland Clinic.

What Knee Pain Symptoms Could Mean For You

If you are experiencing knee pain, it is important to get treatment as soon as possible. Here is what some of the most common knee pain symptoms could mean, as noted by the Mayo Clinic and Cleveland Clinic.

Pain, swelling, and stiffness in the knee

Pain, swelling, or stiffness in your knee may be caused by an injury, infection, or overuse. The Mayo Clinic recommends seeking medical evaluation if the symptoms persist despite home treatments. Occasionally, these symptoms can be cured with:

• Rest
• Ice and elevation
• Compression (wrapping the knee with an elastic bandage)
• Supportive shoes

Difficulty bearing weight on the affected knee

The Mayo Clinic notes that this symptom is a serious symptom that should be evaluated by a doctor as soon as possible. You can use ice and compression for temporary relief until you can get to urgent care.

Limited range of motion

A limited range of motion can make it difficult to perform everyday activities, such as bending down or getting up from a chair. This can happen suddenly if it is caused by an injury, or progress slowly if you have arthritis of the knee. Either way, the Mayo Clinic recommends being evaluated by a doctor. Many times, physical therapy can help gain back some range of motion or prevent further loss of range of motion.

Clicking or popping sounds in the knee

Clicking or popping sounds in your knee can be caused by a variety of factors, including injury or overuse. This is a common ailment for people who are overweight, according to the Cleveland Clinic. Getting a medical evaluation can help you find the source of the clicking or popping, and help you understand how to fix it.

Redness and warmth around the knee joint

If you are experiencing redness and warmth around your knee joint, it may be a sign of an injury or infection inside the knee joint. An infection of the knee joint can be a very serious condition, so a prompt medical evaluation is important, recommends the Mayo Clinic.

When to Seek Urgent Care for Knee Pain

Some knee pain symptoms indicate a serious condition that requires immediate medical attention. These are some signs that the Mayo Clinic notes could indicate an urgent matter.

• Severe pain or swelling - If you are experiencing pain or swelling that does not get better with rest, ice, elevation, and compression then you may have a serious injury.
• Inability to bear weight on the affected knee - The inability to bear weight on an affected knee can indicate a serious injury or infection according to the Mayo Clinic.
• Visible deformity or misalignment of the knee joint - This is a symptom that can indicate a bone fracture or dislocation according to the Mayo Clinic. Only a medical evaluation can determine if you have a broken bone or dislocation.
• Signs of infection - The signs of infection in the knee joint according to the Mayo Clinic include knee pain, swelling, fever, chills, redness, and warmth of the knee. An infection of the knee joint can be very serious and needs medical evaluation right away, according to the Mayo Clinic.
• Symptoms that do not improve with rest and self-care measures - Regardless of what knee pain symptoms you are experiencing, if they do not improve with self-care measures, you should have a medical evaluation. Urgent care is a great option for getting a quick and cost-effective medical evaluation. You can use Solv to find top-rated urgent care near you.

What to Expect When You Go to Urgent Care for Knee Pain

Once you decide to get your knee pain checked out at urgent care, understanding the process can help you be more prepared and at ease about your visit. Here’s what you can expect from most knee pain visits at urgent care.

Physical Examination

When you arrive at the urgent care clinic, you will be checked in through a reception area. They will likely ask about your current symptoms, as well as for your ID and insurance card. After getting checked in, a medical provider will ask for more details about your symptoms and past medical history. A healthcare provider will also conduct a physical examination of your knee to assess the severity of your pain and identify any visible signs of injury or inflammation. They may also ask you to perform certain movements to evaluate your range of motion and any changes in the level of your pain, based on movement.

Diagnostic Tests

Depending on the results of your physical examination, your healthcare provider may order diagnostic tests such as X-rays or an MRI to get a closer look at your knee. These tests can help identify any fractures, dislocations, or other underlying conditions that may be causing your pain.

Treatment Options

Once your healthcare provider has determined the cause of your knee pain, they will recommend a treatment plan. This may include pain management techniques such as ice, heat, or pain relievers. Immobilization with a brace or crutches may also be necessary to prevent further injury. Physical therapy may also be recommended to help you regain strength and flexibility in your knee. In serious cases, surgical repairs may be necessary.

Referral to a Specialist

If your knee pain is severe or requires specialized treatment, your healthcare provider may refer you to a specialist such as an orthopedic surgeon or physical therapist. They will work with you to develop a comprehensive treatment plan that meets your individual needs.

Insurance Coverage for Urgent Care and Knee Pain Treatment

Most insurance plans cover urgent care visits and knee pain treatment. However, it is important to check with your insurance provider to determine what services are covered and what your out-of-pocket costs may be.

Non-Urgent Care Options for Knee Pain

If you are experiencing knee pain, there are many ways you can get care. Urgent care clinics are one way to see a doctor and get treatment quickly, but you also have several non-urgent care options to manage pain and improve your knee joint health. Here are some options you can consider.

Primary Care Physician

Your primary care physician is a great option for managing knee pain. They can evaluate your symptoms, recommend treatment options, and refer you to specialists if surgery or physical therapy is necessary. Your primary care physician can also monitor your progress and adjust your treatment plan as needed.

Physical Therapy

Physical therapy can help you manage knee pain and improve your overall knee function. A physical therapist can design a personalized exercise program to help you strengthen the muscles around your knee and improve your range of motion. They can also teach you techniques to reduce pain and inflammation. You may need a referral from a physician for PT.

Common Misconceptions about Knee Pain and Treatment Options

There are several misconceptions about knee pain and associated treatment options. The most common misconceptions, as outlined by UC Health are:

• Knee pain is almost always caused by arthritis - There are actually many reasons why you may be experiencing knee pain. Sometimes, injuries can cause knee pain for months and even years if they are not addressed and fixed.
• The best way to deal with knee pain is to power through it - This cannot be further from the truth. Inflammation, injuries, and lifestyle habits play a huge role in knee pain, and will not get better unless you have the proper treatment.
• Steroid injections are the only treatment for knee pain - This is a common and false misconception. Steroid injections are used occasionally for reducing inflammation, according to the Mayo Clinic. However, they are not used in many other cases. There are many treatment options for knee pain.
• Surgery is the only way to cure knee pain - There are many non-surgical options available for knee pain. However, the need for surgery really depends on your individual situation and what the root cause of your knee pain is.

It is important to be aware of common misconceptions about knee pain and treatment options to make informed decisions about your care and treatment options.

Self-Care Measures for Knee Pain

There are several self-care measures you can take to alleviate discomfort and promote healing. However, it is important to note that if the knee pain persists or if you cannot bear weight on your knee, you should get a medical evaluation right away.

Rest, Ice, Compression, and Elevation (RICE)

One of the most common ways to treat knee pain is through the RICE method. According to the Mayo Clinic, the RICE method involves resting the knee, applying ice, wrapping the knee in a compression bandage, and elevating the leg. These steps help to reduce swelling and inflammation—as well as reduce pain and promote healing.

Over-the-Counter Pain Relievers

Over-the-counter pain relievers such as ibuprofen or acetaminophen can also help relieve knee pain, according to the Mayo Clinic. These medications can help reduce inflammation and alleviate discomfort. However, it is important to follow the recommended dosage and consult with a healthcare professional if you have any concerns. Long-term use of these medications can lead to other health problems, so if your knee pain persists you should seek medical evaluation.

Stretching and Strengthening Exercises

Stretching and strengthening exercises can help improve flexibility and reduce knee pain. Exercises such as knee extensions, hamstring stretches, and leg lifts can help strengthen the muscles surrounding the knee and improve overall knee function. However, it is important to consult with a healthcare professional before beginning these exercises.

Weight Management and Healthy Lifestyle Habits

Maintaining a healthy weight and engaging in healthy lifestyle habits can also help alleviate knee pain. Excess weight can put extra pressure on the knees, leading to pain and discomfort according to the Mayo Clinic.

Knee Braces and Supports

There are several different types of knee braces and supports available that can help alleviate knee pain. These braces and supports include:

• Compression sleeves
• Knee braces
• Patellar stabilizers

These devices can help provide support and reduce pressure on the knee joint, thus relieving pain and promoting healing. Many braces and support devices are sold at drugstore pharmacy locations.

Surgical Options for Knee Pain

If your knee pain is severe and not responding to non-surgical treatments, your doctor may recommend surgery. There are several surgical options available for knee pain, including arthroscopy and knee replacement.

Arthroscopy

Arthroscopy is a minimally invasive surgical procedure that involves inserting a small camera into your knee joint, according to the American Academy of Orthopaedic Surgeons (AAOS). This procedure allows your surgeon to see inside your knee and diagnose and treat any problems. During arthroscopy, your surgeon may remove damaged tissue, repair torn ligaments, or smooth rough cartilage.

Arthroscopy is typically performed on an outpatient basis, which means you can go home the same day as the surgery. Recovery time varies depending on the severity of your condition, but most people can return to normal activities within a few weeks according to the AAOS.

Knee Replacement

Knee replacement surgery involves removing damaged or diseased parts of your knee joint and replacing them with artificial parts, according to the AAOS. This can relieve pain and improve mobility in people who have severe or irreversible knee damage.

There are several types of knee replacement surgery, including partial knee replacement and total knee replacement. Your surgeon will determine which type of surgery is best for you based on your condition and medical history.

Knee replacement surgery requires a hospital stay and several weeks of recovery time, according to the AAOS. Physical therapy is usually recommended to help you regain strength and mobility in your knee.

Case Studies of Successful Knee Pain Treatment

Many people have found relief from knee pain through surgical and non-surgical treatments. Here are a few examples of successful knee pain treatment:

One case study from Cortho.org describes the success of a total knee replacement in a 63-year-old female patient who suffered from knee osteoarthritis. The patient had a history of knee pain and stiffness for several years, which progressively worsened until it eventually affected her daily activities and mobility.

The surgical procedure involved removing the damaged knee joint and replacing it with an artificial knee implant. The surgeon used a minimally invasive technique to reduce pain and scarring, and the patient was given local anesthesia to avoid complications associated with general anesthesia.

After surgery, the patient received pain management medication and physical therapy to aid in her recovery. She was discharged from the hospital after two days and underwent a home exercise program to regain strength and flexibility in her knee.

The patient reported significant improvement in knee function and quality of life post-surgery. She was able to walk without pain or difficulty and resume her daily activities with ease.

Another case study, found on ClinicalAdvisor.com, describes the case of a 45-year-old male patient with pain and swelling in his left knee. The patient had a history of knee pain and swelling for several years, which had progressively worsened and was now causing difficulty walking and performing daily activities.

The initial evaluation included imaging tests, which revealed a large osteochondral lesion in the patient's left knee joint. The patient underwent arthroscopic surgery to remove the lesion, followed by a course of physical therapy to aid in his recovery.

Keep in mind that every person's experience with knee pain treatment is unique, and results may vary. It's important to discuss your treatment options with your doctor so you can make an informed decision about the best course of treatment for you.

Self-Care Measures That Can Help Knee Pain

Before you seek medical attention, there are steps you can take to help relieve your pain and start you on the path to recovery. Self-care measures for knee pain, as outlined by the Mayo Clinic, include:

• Resting the knee
• Applying ice to the knee
• Elevating the knee
• Using over-the-counter pain medication, such as ibuprofen or acetaminophen

The Mayo Clinic also notes that it is important to note that these measures not be used as a substitute for medical treatment.

Importance of Seeking Prompt Medical Attention for Knee Pain

If you experience knee pain that is not resolved by self-care measures, it is important to seek prompt medical attention. Chronic knee pain can be a symptom of a serious condition, such as a torn ligament, meniscus tear, or arthritis—and delaying treatment can lead to further damage and potentially more invasive treatments in the future.

Urgent care centers provide knee pain patients with effective medical attention. They have the necessary equipment and expertise to diagnose and treat knee pain quickly. They can also refer you to a specialist if needed.

Knee pain can hold you back from being able to do what you want to do—and ignoring knee pain can end up causing more damage to the joint. Urgent care clinics offer a great solution for those who are suffering from knee pain. Use Solv to find an urgent care near you.
