Key takeaways
- Knee bursitis is inflammation of a fluid-filled cushioning sac (bursa) in the knee, most often the prepatellar bursa over the kneecap or the pes anserine bursa on the inner knee.
- It is usually caused by repeated kneeling, overuse, a direct blow, being overweight, or an underlying condition such as osteoarthritis or gout.
- The large majority of cases improve with non-surgical care, and surgery is rarely needed.
- A red, warm, intensely painful knee with fever can signal an infected bursa (septic bursitis) and needs prompt medical attention.
- Treatment is individualized after an in-person evaluation; results depend on the cause and severity.
What is knee bursitis?
Knee bursitis is inflammation of a bursa, one of the small, fluid-filled sacs that cushion the points where skin, tendons, and bone move against each other around the knee. When a bursa becomes irritated it fills with extra fluid and swells, causing the tenderness and puffiness people recognize as knee bursitis. The knee has several bursae, and a few are inflamed far more often than the rest.
The most common form is prepatellar bursitis, inflammation of the bursa directly in front of the kneecap. Because it is often triggered by long periods of kneeling, it is sometimes called “housemaid’s knee” or “carpet-layer’s knee.” The second common form is pes anserine bursitis, which affects a bursa on the inner side of the knee about two to three inches below the joint line and frequently accompanies osteoarthritis. It is important not to confuse knee bursitis with fluid on the knee (a joint effusion), which is excess fluid inside the knee joint itself rather than in a surface bursa.
| Type of knee bursitis | Where it is | Common cause | Hallmark sign |
|---|---|---|---|
| Prepatellar | In front of the kneecap | Repeated kneeling, a fall, or a direct blow | A soft, swollen lump over the kneecap |
| Pes anserine | Inner knee, 2–3 inches below the joint | Osteoarthritis, overuse, tight hamstrings, extra weight | Inner-knee pain climbing stairs or at night |
| Infrapatellar | Just below the kneecap, near the tendon | Running and repetitive jumping (“clergyman’s knee”) | Pain below the kneecap with activity |
What are the symptoms of knee bursitis?
The signs depend on which bursa is involved, but most people notice a combination of the following:
- Swelling: often a squishy, well-defined lump, classically over the kneecap in prepatellar bursitis.
- Pain or tenderness: worse with kneeling, squatting, bending, or direct pressure on the area.
- Warmth and tenderness over the swollen spot.
- Stiffness and reduced range of motion, making the knee feel hard to bend fully.
- Inner-knee pain two to three inches below the joint with pes anserine bursitis, sometimes worse going up stairs or lying on your side at night.
Seek medical care promptly if the knee becomes red, hot, and severely painful, or if you develop a fever, because these can be signs of an infected bursa (septic bursitis) that needs urgent evaluation rather than home care.
What causes knee bursitis?
Knee bursitis usually develops from pressure or friction on a bursa, but several other factors can set it off:
- Prolonged or repeated kneeling: common in flooring, plumbing, gardening, and cleaning work.
- Overuse and repetitive motion: running, jumping, and sports that load the knee.
- A direct blow or fall onto the front of the knee.
- Osteoarthritis and extra body weight, which strain the inner knee and contribute to pes anserine bursitis.
- Inflammatory conditions such as rheumatoid arthritis or gout.
- Infection, when bacteria enter the bursa through a cut or scrape.
How is knee bursitis diagnosed?
Diagnosis starts with a hands-on physical exam to locate the swelling and check your range of motion. To confirm the problem and rule out look-alikes, the clinic may use diagnostic musculoskeletal ultrasound, which shows the inflamed bursa in real time and helps distinguish bursitis from a joint effusion or a different knee problem. If infection or gout is a concern, a small sample of fluid can be drawn and tested. Digital X-ray or fluoroscopy may be used to look for arthritis or other underlying causes. Pinning down the exact cause is what makes targeted, effective treatment possible.
6 non-surgical knee bursitis treatment options
Because most cases respond to conservative care, treatment usually moves from simple measures to targeted procedures only as needed. Here are the main non-surgical options used at Regenerative Joint Clinics in Riverdale, GA.
1. Rest, ice, and activity modification
The first step is to take pressure off the bursa. Resting the knee, applying ice, elevating the leg, and avoiding kneeling or the aggravating activity allow many irritated bursae to settle on their own. Knee pads can protect the area when kneeling is unavoidable.
2. Anti-inflammatory measures
Over-the-counter anti-inflammatory medication and gentle compression can help reduce swelling and discomfort in mild cases. Because these medicines are not right for everyone, ask your provider what is appropriate for you before relying on them.
3. Aspiration (draining the bursa)
When a bursa is tense with fluid, aspiration uses a thin needle to drain it. This relieves pressure quickly and lets the fluid be tested for infection or gout when needed. Performing it with ultrasound guidance improves accuracy and is a common, in-office part of treatment.
4. Image-guided injections
If inflammation lingers after drainage, an image-guided corticosteroid (cortisone) injection can calm the bursa for faster relief. Steroid injections are used for short-term, acute relief and the number per joint each year is limited. For patients who prefer to avoid steroids, Sarapin injections, a non-steroidal botanical option, may be appropriate. Injections are never used on a bursa that may be infected.
5. Physical therapy and targeted strengthening
Physical therapy is key to lasting results, especially for pes anserine bursitis. A therapist guides stretching for tight hamstrings, strengthening for the quadriceps and hip muscles, and movement corrections that reduce the friction causing the problem. You can explore the full range of non-surgical joint pain services the clinic uses to support recovery.
6. Hako-Med therapy and bracing
Hako-Med horizontal therapy is a non-narcotic electrotherapy used to ease pain and inflammation, and supportive bracing or padding can offload the knee while it heals. For select chronic cases linked to tendon irritation, platelet-rich plasma (PRP) may be considered; PRP uses your own concentrated platelets, not stem cells, and is typically elective and not covered by insurance.
When is surgery needed for knee bursitis?
Surgery is rarely necessary. According to the Cleveland Clinic, surgery to remove a bursa is generally reserved for chronic bursitis that has not improved after several months of conservative care, or for certain infected bursae. Because Regenerative Joint Clinics is a non-surgical practice, the focus is on conservative treatment first; if a case ever does require surgery, the team helps coordinate an appropriate referral.
How does Regenerative Joint Clinics treat knee bursitis in Riverdale, GA?
At our Riverdale clinic, treatment follows one coordinated, individualized plan rather than a single isolated procedure. Care typically begins with an accurate diagnosis using a physical exam and ultrasound, moves to relieving pressure and inflammation through aspiration and image-guided injections when appropriate, and then rebuilds strength and mechanics with physical therapy, Hako-Med, and bracing so relief lasts. This combined approach is the same philosophy behind our broader knee pain treatment programs.
Most of this care, including diagnostic ultrasound, aspiration, corticosteroid injections, bracing, and physical therapy, are covered by most major insurers and Medicare; PRP is typically elective. Flexible payment plans are available through Pathways. Care is appointment-based and provided in person at 483 Upper Riverdale Road SW, Suite F, Riverdale, GA 30274. To schedule an evaluation, contact Regenerative Joint Clinics or call (470) 895-0610.
Frequently Asked Questions About Knee Bursitis
Will knee bursitis go away on its own?
Mild knee bursitis often improves on its own within a few weeks with rest, ice, and avoiding the activity that caused it. If swelling and pain persist beyond two to three weeks, keep returning, or the knee becomes red, warm, and very painful, see a clinician, because persistent or infected bursitis needs treatment.
What is the fastest way to relieve knee bursitis?
For sudden, painful swelling, the quickest relief usually comes from draining the fluid (aspiration) and, when appropriate, an image-guided injection to calm the inflamed bursa, alongside rest and activity changes. The right approach depends on the cause, so an in-person evaluation is the safest way to get fast, lasting relief.
Is knee bursitis the same as fluid on the knee?
No. Knee bursitis is inflammation of a bursa, a small fluid sac that cushions the outside of the joint, while fluid on the knee (a joint effusion) is excess fluid inside the knee joint itself. They can look similar but are evaluated and treated differently.
Does knee bursitis treatment require surgery?
Rarely. The large majority of cases respond to non-surgical care such as rest, aspiration, injections, and physical therapy. Surgery to remove the bursa is reserved for chronic cases that have not improved after months of conservative treatment or for certain infected bursae. Regenerative Joint Clinics is a non-surgical clinic and focuses on conservative options first.
Does insurance cover knee bursitis treatment at Regenerative Joint Clinics?
Most components of this care, including diagnostic ultrasound, aspiration, corticosteroid injections, bracing, and physical therapy, are covered by most major insurers and Medicare. Platelet-rich plasma (PRP) is typically elective and not covered. Our team verifies your benefits and offers flexible payment plans through Pathways.
