Prepatellar bursitis

prepatellar bursitis, prepatellar bursitis treatment
Prepatellar bursitis is an inflammation of the prepatellar bursa at the front of the knee It is marked by swelling at the knee, which can be tender to the touch but which does not restrict the knee's range of motion It is most commonly caused by trauma to the knee, either by a single acute instance or by chronic trauma over time As such, prepatellar bursitis commonly occurs among individuals whose professions require frequent kneeling

A definitive diagnosis of the condition can usually be made once a clinical history and physical examination have been obtained, though determining whether or not the bursitis is septic is not as straightforward Treatment of prepatellar bursitis depends on the severity of the symptoms Mild cases may only require rest and icing of the knee A number of different treatment options have been used for severe septic cases, including intravenous antibiotics, surgical irrigation of the bursa, and bursectomy

Signs and symptomsedit

Lateral section of the knee

The primary symptom of prepatellar bursitis is the swelling of the area around the kneecap It generally does not produce a significant amount of pain unless pressure is applied directly to the swelling4 The area of swelling may be red erythema, warm to the touch, or surrounded by cellulitis, particularly if the area has become infected In such cases, the bursitis is often accompanied by fever5:p 608 Unlike arthritis, prepatellar bursitis generally does not affect the range of motion of the knee, though it may cause some discomfort when the knee is completely flexed6:p 360 Flexion and extension of the knee may cause crepitus7:p 20


In human anatomy, a bursa is a small pouch filled with synovial fluid Its purpose is to reduce friction between adjacent structures The prepatellar bursa is one of several bursae of the knee joint, and is located between the patella and the skin8 Prepatellar bursitis is an inflammation of this bursa Bursae are readily inflamed when irritated, as their walls are very thin7:p 22 Along with the pes anserine bursa, the prepatellar bursa is one of the most common bursae to cause knee pain when inflamed9

Prepatellar bursitis is caused by either a single instance of acute trauma to the knee, or repeated minor trauma to the knee The trauma can cause extravasation of nearby fluids into the bursa, which stimulates an inflammatory response2 This response occurs in two phases: The vascular phase, in which the blood flow to the surrounding area increases, and the cellular phase, in which leukocytes migrate from the blood to the affected area7:p 22 Other possible causes include gout, sarcoidosis, CREST syndrome,6:p 359 diabetes mellitus, alcohol abuse, uremia, and chronic obstructive pulmonary disease7:p 22 Some cases are idiopathic, though these may be caused by trauma that the patient does not remember5:pp 607–8

The prepatellar bursa and the olecranon bursa are the two bursae that are most likely to become infected, or septic10 Septic bursitis typically occurs when the trauma to the knee causes an abrasion, though it is also possible for the infection to be caused by bacteria traveling through the blood from a pre-existing infection site11 In approximately 80% of septic cases, the infection is caused by Staphylococcus aureus; other common infections are Streptococcus, Mycobacterium, and Brucella6:p 359 It is highly unusual for septic bursitis to be caused by anaerobes, fungi, or Gram-negative bacteria5:p 608 In very rare cases, the infection can be caused by tuberculosis12


There are several types of inflammation that can cause knee pain, including sprains, bursitis, and injuries to the meniscus9 A diagnosis of prepatellar bursitis can be made based on a physical examination and the presence of risk factors in the person's medical history; swelling and tenderness at the front of the knee, combined with a profession that requires frequent kneeling, suggest prepatellar bursitis2 Swelling of multiple joints along with restricted range of motion may indicate arthritis instead5:p 608

A physical examination and medical history are generally not enough to distinguish between infectious and non-infectious bursitis; aspiration of the bursal fluid is often required for this, along with a cell culture and Gram stain of the aspirated fluid6:p 360 Septic prepatellar bursitis may be diagnosed if the fluid is found to have a neutrophil count above 1500 per microliter,5:p 608 a threshold significantly lower than that of septic arthritis 50,000 cells per microliter6:p 360 A tuberculosis infection can be confirmed using a roentgenogram and urinalysis12


It is possible to prevent the onset of prepatellar bursitis, or prevent the symptoms from worsening, by avoiding trauma to the knee or frequent kneeling5:p 610 Protective knee pads can also help prevent prepatellar bursitis for those whose professions require frequent kneeling and for athletes who play contact sports, such as American football, basketball, and wrestling13


Non-septic prepatellar bursitis can be treated with rest, the application of ice to the affected area, and anti-inflammatory drugs, particularly ibuprofen Elevation of the affected leg during rest may also expedite the recovery process13 Severe cases may require fine-needle aspiration of the bursa fluid, sometimes coupled with cortisone injections11 However, some studies have shown that steroid injections may not be an effective treatment option14 After the bursitis has been treated, rehabilitative exercise may help improve joint mechanics and reduce chronic pain15:p 2320

Opinions vary as to which treatment options are most effective for septic prepatellar bursitis6:p 360 McAfee and Smith recommend a course of oral antibiotics, usually oxacillin sodium or cephradine, and assert that surgery and drainage are unnecessary5:p 609 Wilson-MacDonald argues that oral antibiotics are "inadequate", and recommends intravenous antibiotics for managing the infection1 Some authors suggest surgical irrigation of the bursa by means of a subcutaneous tube6:p 36016 Others suggest that bursectomy may be necessary for intractable cases; the operation is an outpatient procedure that can be performed in less than half an hour17:p 357


The various nicknames associated with prepatellar bursitis arise from the fact that it commonly occurs among those individuals whose professions require frequent kneeling, such as carpenters, carpet layers, gardeners, housemaids, mechanics, miners, plumbers, and roofers245:p 607 The exact incidence of the condition is not known; it is difficult to estimate because only severe septic cases require hospital admission, and mild non-septic cases generally go unreported5:p 607 Prepatellar bursitis is more common among males than females It affects all age groups, but is more likely to be septic when it occurs in children18
