Understanding Patella Fractures and Their Common Symptoms

The patella, also known as the kneecap, is a flat bone that plays a crucial role in knee movement. However, it's not immune to fractures, which can occur due to various reasons such as trauma, sports injuries, or falls. When this happens, it's essential to understand the common symptoms associated with patella fractures and how they are treated.

Weightbearing Restrictions

In some cases, patients may be required to avoid weightbearing on their affected leg for 6 to 8 weeks to ensure proper healing of the broken ends of bone. This is crucial in maintaining the correct alignment of the bone fragments while they fuse together. Fortunately, some fractures allow patients to bear weight on their leg while wearing a cast or brace, under the guidance of their doctor.

Bruising and Deformity

One of the most common symptoms of patella fractures is bruising, which can be significant in cases of fracture or tendon tear. In addition, deformity may occur, particularly with fractures or dislocations, causing the knee joint to appear misshapen. This deformity can lead to difficulties in bending or straightening the knee.

Locked Joint and Instability

In some instances, patients may experience a locked joint, making it challenging to bend or straighten their knee. The leg may buckle when trying to stand up or walk, which is a common symptom of patella fractures. Furthermore, instability can occur, making it difficult for individuals to support their weight on the affected leg.

Other Common Symptoms

In addition to these symptoms, patients with patella fractures may also experience noises such as popping or snapping sensations, particularly during the time of injury. Inflammation can cause severe swelling, which can be so debilitating that it's impossible to place any weight on the leg. Knee pain is often more noticeable during specific activities like walking stairs or kneeling.

Treating Patella Fractures

Treatment for patella fractures typically involves immobilizing the knee using casts or splints to keep it straight and prevent motion in the leg. In some cases, surgery may be necessary if the bone fragments are out of place (displaced). Physical therapy is also essential in restoring knee function and strength after healing.

Patella fractures can result in a range of symptoms, from bruising and deformity to locked joints and instability. Understanding these common symptoms is crucial in seeking appropriate medical attention and ensuring proper treatment. By following the guidance of their doctor and undergoing physical therapy, individuals with patella fractures can make a full recovery and regain normal knee function.
