S82.014A Nondisplaced osteochondral fracture of right patella, initial encounter for closed fracture

Name of the Condition

• Nondisplaced osteochondral fracture of right patella, initial encounter for closed fracture

Summary

This condition involves a fracture of the right patella (kneecap) where the bone and overlying cartilage are damaged but the fragments remain in their normal position. The injury is classified as closed, meaning the skin is intact, and it is the initial encounter for this specific fracture. The nondisplaced nature indicates no significant misalignment of the bone-cartilage fragments.

Causes

Direct trauma to the right knee, such as a fall onto the kneecap, a forceful blow, or a high-impact injury (e.g., sports injury or motor vehicle accident). The fracture occurs when the force is sufficient to damage both the bone and cartilage but not enough to displace the fragments.

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 right knee.
• Swelling and bruising around the kneecap.
• Difficulty straightening or bearing weight on the right knee.
• 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. CT or MRI may be used to assess cartilage damage or complex fractures.

Treatment Options

• Immobilization with a brace or cast to allow healing.
• Pain management with medications or ice.
• Physical therapy to restore strength and mobility.
• Surgical intervention if the fracture does not heal properly or causes persistent symptoms.

Prognosis and Follow-Up

Most nondisplaced fractures heal with conservative treatment, but recovery may take several weeks. Follow-up appointments are necessary to monitor healing and adjust treatment. Long-term outcomes depend on the extent of cartilage damage and adherence to rehabilitation.

Complications

• Delayed healing or nonunion.
• Post-traumatic arthritis due to cartilage damage.
• Chronic pain or stiffness in the knee.
• Risk of future fractures if bone density is compromised.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid sudden, forceful movements that strain the knee.
• Warm up properly before physical activity.

When to Seek Professional Help

Seek immediate care if you experience severe knee pain, inability to bear weight, or visible deformity. Contact a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

Document the fracture as nondisplaced, the right patella involvement, and the initial encounter for a closed fracture. Include details on imaging results, treatment provided, and any follow-up care to support accurate coding. Ensure the encounter is classified as initial for proper sequencing.
