Front and Center: Understanding Anterior Knee Pain

Anterior knee pain is a common condition that can affect individuals of all ages and activity levels. However, variations in reported incidence and prevalence of anterior knee pain may arise from differing populations assessed, inconsistencies in diagnosis, and lack of high-quality evidence for assessment.

The lack of a definitive gold standard method for clinically diagnosing anterior knee pain may also contribute to its underestimation and underreporting. Regardless, living with this condition is challenging and affects the quality of life of those experiencing it due to diminishing knee function, so educating others about this condition is important.

So, in this article, we will provide an in-depth overview of anterior knee pain, including its definition, risk factors, symptoms, prevention strategies, medical conditions associated with it, management options, and when to seek medical attention.

What Do You Mean By Anterior Knee Pain?

Anterior knee pain refers to the discomfort or pain experienced in the front of the knee. It's a condition that can be caused by various factors, including overuse, trauma, or underlying medical conditions.

The pain is typically localised around the patella, also known as the knee cap, and can range from mild to severe. Individuals with anterior knee pain often describe it as a dull ache or a sharp, stabbing sensation. It can be exacerbated by activities that involve a bent knee, such as running, squatting, or climbing stairs.

Risk Factors of Anterior Knee Pain

While anterior knee pain can occur in anyone, certain factors may increase the likelihood of developing this condition.

Engaging in activities that place repetitive stress on the knee joint, such as running or jumping.

Poor biomechanics, such as misalignment of the patella or weakness in the surrounding muscles, can contribute to anterior knee pain.

Obesity

Previous knee injuries

Certain medical conditions, such as arthritis or patellar tendinitis

Symptoms of Anterior Knee Pain

Recognising the symptoms of anterior knee pain is crucial for early detection and appropriate management.

Individuals with this condition may experience pain or discomfort in the front of the knee, especially during activities that involve knee movement. The pain may worsen with prolonged sitting or when climbing stairs. Swelling or a sensation of grinding or popping in the knee joint may also be present.

Note, however, that the severity and frequency of symptoms may vary from person to person, so it's still best to consult a healthcare professional in case of increasing severity of pain.

How to Prevent Anterior Knee Pain

Fortunately, there are several strategies that can help reduce the risk of developing this condition.

Maintaining a healthy body weight is important, as excess weight places added stress on the knee joint. Engaging in regular physical activity, focusing on exercises that strengthen the muscles around the knee, can also help prevent anterior knee pain.

Wearing appropriate footwear and using proper techniques during sports or other activities that involve the knee joint can also help reduce the risk of injury.

Medical Conditions Associated With Anterior Knee Pain

Anterior knee pain can arise from various medical conditions, each with its own set of causes and treatment options. Understanding these conditions can provide insights into the underlying causes of anterior knee pain. Some of the commonly associated medical conditions include:

Patellofemoral Pain Syndrome

Patellofemoral pain syndrome is a condition that involves the dysfunction and irritation of the patellofemoral joint, where the patella (or knee cap) meets the femur (or the thigh bone).

Increased patellar mobility, patellar hypermobility, and patella alta (high-riding patella) have been associated with an elevated risk of this patellofemoral pain syndrome. Tightness or inflexibility in the iliotibial band, hamstrings (or the posterior thigh muscles), and calf muscles may contribute to altered patellar tracking and may also predispose individuals to this condition.

Patellofemoral joint pain may manifest as anterior knee pain, especially during activities that involve knee flexion and extension, such as squatting or climbing stairs.

Chondromalacia Patella

Chondromalacia of the patella, also known as "runner's knee," is a condition characterised by the softening and degeneration of the cartilage on the underside of the patella. This can lead to pain and discomfort in the front of the knee, especially during activities that involve knee flexion and extension.

Lateral Compression Syndrome

Lateral compression syndrome occurs when there is compression or irritation of the structures on the outer side of the knee joint. This can result in anterior knee pain, swelling, and a sensation of instability.

Patella Arthritis

Patella arthritis is a degenerative condition that affects the patella joint. It can cause pain, stiffness, and swelling in the front of the knee. Individuals with patella arthritis may experience difficulty with activities that require bending or straightening the knee.

Patella Maltracking

Patella maltracking refers to the misalignment of the patella, where it does not move smoothly within the groove of the femur. This can lead to anterior knee pain, instability, and a sensation of the patella "catching" or "grinding" during movement.

Patellar Tendinitis

Patellar tendinitis, also known as "jumper's knee," is the inflammation of the patellar tendon. It commonly affects individuals who participate in activities that involve repetitive jumping or landing, causing pain and tenderness in the front of the knee.

Patella Tendinopathy

Patella tendinopathy is a chronic condition characterised by the degeneration and weakening of the patellar tendon. It can cause pain, swelling, and stiffness in the front of the knee, particularly during activities that involve jumping or running.

Quadriceps Tendinitis

Quadriceps tendinitis is the inflammation of the quadriceps tendon, which connects the quadriceps muscles to the patella. It can lead to anterior knee pain, tenderness, and difficulty with activities that require the use of the quadriceps muscles.

Knee Osteoarthritis

Anterior knee pain, often experienced as discomfort in the front of the knee, can signal various underlying conditions. One significant connection lies with knee osteoarthritis, particularly involving the joint between the kneecap (patella) and the thigh bone (femur), known as patellofemoral osteoarthritis.

Patellofemoral osteoarthritis manifests as pain, stiffness, and swelling in the anterior knee region. This condition arises from the degeneration of cartilage within the patellofemoral joint, leading to discomfort and impaired mobility. Individuals experiencing anterior knee pain may find that patellofemoral osteoarthritis is the underlying cause.

Singapore General Hospital indicates that knee osteoarthritis affects over 10% of adults in Singapore, with a significant uptick noted among individuals aged 40 to 60.

Ways to Relieve Anterior Knee Pain

Managing anterior knee pain usually involves a combination of lifestyle modifications, pain medication, physiotherapy, and, in some cases, surgery. The specific management approach will depend on the underlying cause and severity of the condition. Here are some commonly recommended methods to relieve pain in the anterior knee:

Lifestyle Modification and Rest

One of the first steps in managing anterior knee pain is to modify activities that worsen the symptoms and allow the knee to rest. This may involve avoiding high-impact exercises, reducing the duration or intensity of physical activities, or using protective equipment, such as knee braces, to provide additional support.

Pain Medication

Over-the-counter pain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), can help alleviate the pain and reduce inflammation associated with anterior knee pain. These temporary and short-term ways of pain relief work by targeting the biological process responsible for inflammation and pain. If symptoms persist despite continuous taking of these medicines, it's important to consult a medical practitioner on the steps to take to alleviate the dull, aching pain that you're experiencing.

Physiotherapy

Physiotherapy for knee pain plays a crucial role in the management of anterior knee pain. A physiotherapist can design a personalised exercise program to strengthen the muscles around the knee, improve flexibility, and correct any biomechanical issues that may contribute to the condition. Additionally, they may use techniques such as manual therapy, ice or heat therapy, and electrical stimulation to provide pain relief and promote healing.

Surgery

In severe cases where conservative treatments have been ineffective, knee surgery may be considered. The specific surgical procedure will depend on the underlying cause of the anterior knee pain. Common surgical interventions include arthroscopy, where the joint is examined and repaired using small incisions, or realignment procedures to correct patella maltracking.

When to See a Doctor

Seeking timely medical attention for anterior knee pain is crucial to determine the underlying cause, receive appropriate treatment, and prevent potential complications. If you're experiencing anterior knee pain, it is advisable to seek consultation from a healthcare professional under the following circumstances:

The pain is severe and persists despite rest and over-the-counter pain medication.

There is significant swelling or redness around the knee joint.

The knee becomes locked or gives way during movement.

The pain is accompanied by a fever or other systemic symptoms.

A healthcare professional can assess the underlying cause of the anterior knee pain through available diagnostic options like physical examination and history taking, blood tests and other laboratory tests, and imaging modalities like x-rays and MRI scans. Based on the findings, they may then recommend appropriate treatment options based on an individual's specific condition.
