Understanding Knee Bursitis
Knee bursitis is a common condition that can cause significant discomfort and limit mobility. This section provides an overview of knee bursitis and its symptoms.
Definition and Overview
Knee bursitis is a condition where one or more small fluid-filled sacs, known as bursae, near the knee joint become inflamed. The bursae play a crucial role in reducing friction and cushioning pressure points between bones, tendons, muscles, and skin near the joints. Inflammation of these sacs can lead to pain and restricted movement. Knee bursitis most commonly occurs over the kneecap or on the inner side of the knee below the joint [1].
The inflammation can result from a variety of causes, including direct trauma or repetitive stress on the knee. Individuals whose occupations involve prolonged kneeling on hard surfaces are particularly at risk.
Symptoms of Knee Bursitis
The symptoms of knee bursitis can vary in intensity and may include:
- Warmth: The affected area of the knee may feel warmer than the surrounding regions.
- Tenderness: Touching or pressing on the inflamed area can cause discomfort.
- Swelling: Noticeable swelling may occur in the affected area.
- Pain: Pain can be experienced either during movement or at rest, making daily activities challenging.
| Symptom |
Description |
| Warmth |
Increased temperature in the affected area |
| Tenderness |
Pain upon touching |
| Swelling |
Noticeable puffiness in the knee |
| Pain |
Discomfort during movement or at rest |
These symptoms are often exacerbated by activities that put pressure on the knee, such as kneeling or bending. If left untreated, knee bursitis can lead to more severe complications, including chronic pain and limited joint mobility.

Understanding the symptoms and causes of knee bursitis is the first step towards effective management and relief.
Causes and Risk Factors
Understanding the causes and risk factors of knee bursitis can help in managing and preventing this painful condition, often referred to as a "knot on kneecap."
Direct Trauma vs. Overuse
Knee bursitis can be the result of either direct trauma or overuse. Direct trauma involves a sudden injury to the knee, such as a blow or a fall. This can cause bleeding into the bursa sac, leading to swelling and discomfort. Prepatellar bursitis, in particular, can develop from a direct blow, causing immediate swelling and pain. This type of bursitis can also result from repeated minor injuries, which lead to irritation and thickening of the bursa [2].
On the other hand, overuse bursitis develops slowly over time due to continuous friction and irritation of the bursae. This is common in individuals whose activities involve frequent kneeling on hard surfaces, such as plumbers, carpet layers, and gardeners [1].
| Cause |
Description |
Example Activities |
| Direct Trauma |

Kneeling on hard surfaces |
Occupational Influence on Knee Bursitis
Certain occupations significantly increase the risk of developing knee bursitis due to the nature of the work involved. Jobs that require prolonged periods of kneeling or repetitive knee movements put individuals at a higher risk of irritating the bursa. For example, plumbers, carpet layers, roofers, and gardeners often experience this condition due to the repetitive strain placed on their knees.
Occupational knee bursitis is not only limited to physical labor jobs. Athletes, particularly those involved in sports requiring frequent knee use, such as football, wrestling, and soccer, are also prone to developing this condition. The repetitive movements and physical impact experienced during these activities contribute to the inflammation of the bursa.
To mitigate the risk of knee bursitis in such professions, individuals are encouraged to use protective gear and take precautionary measures. Wearing knee pads, using proper techniques, and taking regular breaks can help reduce the strain on the knees. For additional support, knee wraps for pain can be beneficial.
By identifying the specific causes and risk factors associated with knee bursitis, individuals can take proactive steps to prevent and manage this condition effectively. For more information on exercises and stretches that can help, check out our guide on the vastus medialis stretch.
Diagnosis and Medical Evaluation
Accurate diagnosis is crucial for determining the appropriate treatment for knee bursitis, often recognized as a painful "knot on the kneecap." Medical professionals use a combination of physical examinations and diagnostic tests to evaluate the condition.
Physical Examination
A comprehensive physical examination is the first step in diagnosing knee bursitis. During this assessment, healthcare providers will:
- Inspect the knee for signs of swelling, redness, and warmth.
- Palpate the kneecap and surrounding areas to identify tenderness and the presence of a fluid-filled sac (bursa).
- Assess the range of motion and flexion of the knee to evaluate how the bursitis is affecting knee function.
In many cases, the diagnosis of prepatellar bursitis is evident from the physical examination alone [2]. However, additional tests may be required to rule out other conditions or complications.
Imaging Tests and Fluid Aspiration
To further investigate the cause of the knee pain and confirm the diagnosis, medical professionals may employ imaging tests and fluid aspiration.
Imaging Tests
Imaging tests such as X-rays, ultrasound, or MRI scans may be recommended to:
- Rule out fractures, especially if there is immediate swelling after an injury.
- Evaluate the extent of inflammation and fluid accumulation in the bursa.
- Identify any underlying issues such as arthritis or tendonitis.
| Imaging Test |
Purpose |
| X-ray |
Rule out fractures |
| Ultrasound |
Assess fluid accumulation |
| MRI |
Evaluate soft tissue and underlying conditions |
These imaging tests provide a detailed view of the knee structures, helping to pinpoint the exact cause of the symptoms.
Fluid Aspiration
In cases where infection or other complications are suspected, fluid aspiration (arthrocentesis) may be performed. This involves extracting a sample of the bursa fluid using a needle for laboratory analysis [3].
Fluid aspiration helps to:
- Detect the presence of bacteria, indicating an infection.
- Identify crystals, which may suggest gout.
- Determine the nature of inflammation.
Fluid analysis can provide critical information for tailoring the most effective treatment plan, ensuring proper management of knee bursitis.

Osgood-Schlatter Disease in Children
Definition and Common Causes
Osgood-Schlatter disease is a prevalent cause of knee pain in children and adolescents. This condition is categorized as a repetitive strain injury, primarily resulting from overuse of the patellar tendon. The patellar tendon connects the kneecap to the shin bone, and activities like running, jumping, and climbing can stress this tendon excessively. This overuse leads to inflammation and pain, particularly at the point where the tendon attaches to the shin bone.
The primary activities that contribute to Osgood-Schlatter disease are:
- Running
- Jumping
- Climbing
- Training for sports
These high-impact activities exacerbate the strain on the patellar tendon, making it a common issue among active children and teenagers.
Age Group Affected and Growth Spurts
Osgood-Schlatter disease mainly affects children who are still growing, particularly those undergoing a growth spurt. The age group most susceptible to this condition is between 11 and 14 years old [4]. During growth spurts, the bones, muscles, and tendons grow at different rates, leading to increased tension on the patellar tendon.
| Age Group |
Susceptibility |
| 11-14 years |
High |
This discrepancy in growth rates can cause the patellar tendon to overstretch, resulting in inflammation and pain. While most children with Osgood-Schlatter disease do not experience long-term complications, there are rare instances where the growth plate can pull away from the shinbone, leading to chronic pain or swelling [5].
Treatment for Osgood-Schlatter disease usually involves allowing the condition to resolve as the child's bones stop growing. Over-the-counter pain relievers, such as acetaminophen and ibuprofen, can help manage the discomfort. Additionally, physical therapy and specific exercises can assist in stretching and strengthening the muscles, alleviating symptoms and promoting recovery.
