S82.041 Displaced comminuted fracture of right patella

Name of the Condition

• Displaced comminuted fracture of right patella

Summary

This condition involves a complex fracture of the kneecap (patella) on the right side, where the bone is broken into multiple pieces and the fragments are displaced from their normal position. The severity depends on the extent of fragmentation and displacement, which can affect joint stability and function.

Causes

Direct trauma to the knee is the primary cause, often resulting from falls, motor vehicle accidents, or high-impact sports injuries. Forceful contraction of the quadriceps muscle or a direct blow to the kneecap can also lead to this type of fracture.

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

• Severe pain in the right knee.
• Swelling and bruising around the kneecap.
• Inability to straighten or bear weight on the right leg.
• Visible deformity or a gap in the kneecap area.
• Tenderness to touch.

Diagnosis

Diagnosis typically involves a physical examination to assess knee movement, swelling, and tenderness. Imaging studies, such as X-rays or CT scans, are used to confirm the fracture, evaluate the number of fragments, and determine the degree of displacement.

Treatment Options

• Immobilization with a knee brace or cast to stabilize the fracture.
• Pain management with medications or ice.
• Surgical intervention, such as open reduction and internal fixation, to realign and secure the bone fragments.
• Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture and the effectiveness of treatment. Most patients recover with proper care, but follow-up imaging may be needed to monitor healing. Long-term outcomes can include restored function or, in some cases, persistent stiffness or arthritis.

Complications

• Nonunion or delayed healing of the fracture.
• Post-traumatic arthritis in the knee joint.
• Infection, particularly if surgery is performed.
• Chronic pain or reduced range of motion.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by using assistive devices if needed.
• Strengthen surrounding muscles to support the knee joint.

When to Seek Professional Help

Seek immediate medical attention if you experience severe knee pain, swelling, or an inability to move the leg after an injury. Prompt evaluation is crucial to prevent complications and ensure proper treatment.

Tips for Medical Coders

Document the laterality (right) and the specific fracture characteristics (displaced, comminuted) to accurately assign this code. Ensure clinical documentation supports the displacement and fragmentation to justify the code selection.
