S82.044 Nondisplaced comminuted fracture of right patella

Name of the Condition

• Nondisplaced comminuted fracture of right patella

Summary

This condition involves a fracture of the right kneecap (patella) where the bone is broken into multiple pieces, but the fragments remain in their normal anatomical position. The severity depends on the number of fragments and the integrity of the joint surface, which can impact knee function and stability.

Causes

Direct trauma to the right knee, such as a fall onto the kneecap, a forceful blow, or a high-impact injury from sports or accidents, is the primary cause. Muscle contractions, like a sudden quadriceps pull, can also lead to comminuted fractures.

Risk Factors

• Participation in high-impact or contact sports.
• Osteoporosis or bone-weakening conditions.
• Advanced age, which may reduce bone density.
• Previous knee injuries or surgeries.

Symptoms

• Severe right knee pain and swelling.
• Inability to straighten or bear weight on the right leg.
• Tenderness and bruising around the right knee.
• A "popping" sensation at the time of injury.

Diagnosis

Diagnosis typically involves a physical examination to assess right knee movement and tenderness. Imaging tests, such as X-rays or CT scans, are used to confirm the fracture, evaluate fragment configuration, and rule out displacement.

Treatment Options

• Immobilization with a knee brace or cast to stabilize the fracture.
• Pain management with medications or ice.
• Physical therapy to restore range of motion and strength.
• Surgical intervention if fragments become displaced or joint alignment is compromised.

Prognosis and Follow-Up

Most nondisplaced comminuted fractures heal with immobilization and physical therapy, though recovery may take several weeks to months. Follow-up imaging and clinical assessments are used to monitor healing and guide rehabilitation.

Complications

• Delayed union or nonunion of fragments.
• Post-traumatic arthritis due to joint surface damage.
• Chronic pain or stiffness in the right knee.
• Risk of future patellar instability.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid sudden, forceful knee movements.
• Strengthen quadriceps and surrounding muscles to support the joint.

When to Seek Professional Help

Seek immediate care for severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., fever, increased swelling, redness).

Tips for Medical Coders

Document the side (right), fracture type (comminuted), and displacement status (nondisplaced) to accurately reflect the condition. Include clinical details supporting the diagnosis, such as imaging findings or physical exam results, to justify code assignment.
