S82.03 Transverse fracture of patella

Name of the Condition

• Transverse fracture of patella

Summary

This condition involves a horizontal break across the kneecap (patella), a triangular bone that protects the knee joint. The fracture line runs perpendicular to the bone’s long axis, and the severity depends on whether the bone fragments are displaced or remain aligned.

Causes

Direct trauma to the knee, such as a fall onto the kneecap, a blow from an object, or a forceful contraction of the quadriceps muscle. High-impact injuries, like those from sports or motor vehicle accidents, are common triggers.

Risk Factors

• Participation in activities with a high risk of knee injury, such as contact sports or skiing.
• Osteoporosis or other bone-weakening conditions.
• Previous knee injuries or surgeries.
• Advanced age, which may reduce bone density.

Symptoms

• Sudden, severe pain in the knee.
• Swelling and bruising around the kneecap.
• Inability to straighten the knee or bear weight.
• Visible deformity or a gap in the kneecap area.
• A "popping" sensation at the time of injury.

Diagnosis

A physical examination to assess knee movement, swelling, and tenderness. Imaging studies, typically X-rays, to confirm the fracture and evaluate bone alignment. In some cases, a CT scan may be used to assess complex fractures or displacement.

Treatment Options

• Conservative management: Immobilization with a brace or cast to allow healing.
• Surgical intervention: Required if the fracture is displaced or unstable, involving realignment and fixation of bone fragments.
• Rehabilitation: Physical therapy to restore movement, strength, and function after healing.

Prognosis and Follow-Up

Most transverse fractures heal with proper treatment, but recovery time varies. Follow-up appointments monitor healing progress, and physical therapy may be recommended to prevent stiffness. Complications like arthritis or reduced mobility can occur if the fracture is severe or improperly aligned.

Complications

• Nonunion or delayed healing of the fracture.
• Post-traumatic arthritis in the knee joint.
• Chronic pain or reduced range of motion.
• Infection (if surgical intervention is required).

Lifestyle & Prevention

• Use protective gear during high-impact activities.
• Maintain bone health through diet and exercise to reduce fracture risk.
• Avoid falls by using assistive devices if balance is impaired.
• Strengthen knee muscles through targeted exercises to improve stability.

When to Seek Professional Help

Seek immediate medical attention if you experience severe knee pain, swelling, or an inability to bear weight after an injury. Prompt evaluation is critical to assess the fracture and prevent complications.

Tips for Medical Coders

Document the fracture type (transverse), laterality (unspecified in this code), and any displacement or associated injuries. Ensure clinical notes support the diagnosis, as coding requires specificity about the fracture pattern and treatment approach.
