The kneecap, or patella, is a small, but vital bone located at the front of the knee joint. It serves several essential functions, including protecting the knee joint and aiding movement by providing leverage for the muscles that straighten the leg. Because of its location and role, a broken kneecap can significantly impact mobility and daily activities. Jonathan L. Glashow MD, Orthopedic Surgery & Sports Medicine shares more.
The Incidence of Broken Kneecaps
Broken kneecaps are not as common as some other bone fractures, but they do occur frequently enough to warrant discussion.
Johns Hopkins Medicine says, “The patella is a sesamoid bone: a round bone embedded in a tendon that shields and protects a joint. In the case of the patella, ligaments attach it to both the thigh muscles (quadriceps) and the shinbone (tibia). In some cases, kneecap fractures can be accompanied by injuries to knee tendons and ligaments due to the initial impact to the knee.”
The National Library of Medicine, National Center for Biotechnology Information claims that patellar fractures account for about 1% to 2% of all fractures. This makes them relatively uncommon compared to fractures in other areas such as the wrist or ankle.
Who Can Suffer a Patellar Fracture?
While anyone can suffer a broken kneecap, certain groups may be at higher risk. Active individuals, particularly those participating in contact sports or activities that involve jumping or running, are more susceptible. Older adults also face an increased risk due to conditions such as osteoporosis, which weakens bones and makes them more likely to fracture.
A broken kneecap can result from various incidents. The most common causes include:
- Falls
- Car Accidents
- Sports Injuries
- Overuse
What Are the Symptoms of a Broken Kneecap?
Recognizing the signs of a broken kneecap is crucial for prompt treatment. Common symptoms include:
- Intense Pain: Immediate pain at the knee, often exacerbated by movement.
- Swelling and Bruising: The knee may swell and display bruising soon after the injury.
- Inability to Bend the Knee: Individuals may find it difficult or impossible to fully extend or flex the knee.
- Deformity: In some cases, the kneecap may appear misaligned.
Patellar Fracture Diagnosis and Treatment
If a kneecap fracture is suspected, Dr. Glashow will typically perform a physical examination and may order imaging tests such as X-rays or an MRI to confirm the diagnosis and assess the severity of the injury. Treatment varies depending on the type and severity of the fracture. Options may include:
- Immobilization: Using a brace or splint to keep the knee stable.
- Physical Therapy: Gradual rehabilitation exercises to restore movement and strength.
- Surgery: In cases where the fracture is severe or the kneecap is displaced, surgical intervention may be necessary.
While broken kneecaps are not the most frequent fractures, they can have a significant impact on an individual’s mobility and quality of life. Understanding the risks, causes and symptoms can aid in prevention and prompt treatment.
If you suspect you’ve suffered a knee injury, it’s essential to consult with Jonathan L. Glashow MD, Orthopedic Surgery & Sports Medicine for an accurate diagnosis and an appropriate treatment plan. Taking care of your knee health is vital to maintaining an active lifestyle and reducing the risk of injury.
