Knee bursitis is a prevalent condition that often flies under the radar, yet it can cause substantial discomfort, particularly among women over the age of 40. Grasping the symptoms, recognizing the risk factors, and learning effective treatments are crucial for alleviating pain and retaining mobility. This article delves into the nature of knee bursitis, explores its two primary forms, examines why women in this demographic are at heightened risk, and provides practical advice for relief.

What Is Knee Bursitis?

Knee bursitis manifests when the small fluid-filled sacs known as bursae, located near the knee joint, become inflamed. These bursae serve as cushions, ensuring bones, tendons, and muscles move smoothly by minimizing friction and safeguarding the knee during motion. When these sacs become irritated or injured, they swell and cause pain and tenderness. Laura Moore, MD, PhD, an orthopedic surgeon at Hospital for Special Surgery and Assistant Professor in Orthopedic Surgery at Weill Cornell Medical College, explains, “Knee bursitis is more than a minor annoyance; it can significantly impede daily activities, particularly for women predisposed to risk factors like obesity and diabetes.”

The Two Types of Knee Bursitis

Two main types of knee bursitis exist: prepatellar and pes anserine. Prepatellar bursitis impacts the bursa located in front of the kneecap, frequently occurring in individuals who kneel repeatedly, such as gardeners or housekeepers. Pes anserine bursitis, on the other hand, affects the bursa on the inner side of the knee just below the joint. This form is more prevalent in women over 40, especially those dealing with obesity or osteoarthritis.

Key Symptoms Women Over 40 Should Watch For

For women in this age bracket, it is essential to be vigilant about certain symptoms:

• Pain and tenderness around the knee, noticeable particularly when touched or during movement

• Swelling that may be localized above, below, or beside the kneecap

• Warmth and redness in the affected area

• Stiffness and limited range of motion

• In severe cases, fever or chills if the bursitis is infected (septic bursitis)​

If these symptoms persist or worsen, seeking medical advice is important, as untreated bursitis can lead to chronic pain and mobility issues.

Risk Factors for Knee Bursitis in Women

Certain factors increase the risk of knee bursitis in women over 40:

• Diabetes: Poor circulation and higher risk of infection make diabetics more susceptible to bursitis complications.​

• A change in gait: Alterations in walking patterns due to aging, injury, or arthritis can put extra stress on the knee bursae.​

• Obesity: Excess weight increases pressure on the knee joints, raising the risk of both bursitis and osteoarthritis.​

Effective Treatment Options

Several remedies can help relieve knee bursitis symptoms and speed recovery:

• Consider knee pads or compression sleeves: These provide cushioning and reduce friction, especially for those who kneel or stand for long periods.​

• Reduce pain with the right meds: Over-the-counter NSAIDs (like ibuprofen) can help control pain and inflammation. For persistent pain, a doctor may recommend prescription medication or corticosteroid injections.​

• Treat a limp ASAP: Addressing changes in gait promptly can prevent further knee strain and reduce the risk of recurring bursitis.​

Physical therapy is also recommended to restore strength and flexibility, and in rare cases, surgery may be needed for chronic or infected bursitis.​

The Bottom Line on Knee Bursitis

Knee bursitis is a manageable condition with the right care. Early recognition of symptoms, especially in women over 40, can prevent complications and improve quality of life. By addressing risk factors, using supportive aids, and seeking timely treatment, most people can expect a full recovery and return to normal activities.​
