S82.022S Displaced longitudinal fracture of left patella, sequela

Name of the Condition

• Displaced longitudinal fracture of left patella, sequela

Summary

A displaced longitudinal fracture of the left patella, sequela, refers to the residual effects of a previously treated or healed vertical break in the kneecap that remains misaligned. This condition represents the long-term consequences of the original injury, which may include persistent pain, functional limitations, or structural changes in the knee joint.

Causes

The sequela arises from a prior displaced longitudinal fracture of the left patella, typically resulting from direct trauma to the knee, such as a fall, forceful impact, or sudden muscle contraction. The original injury may have been caused by high-impact events like motor vehicle accidents or sports-related incidents.

Risk Factors

• History of prior knee trauma or fracture.
• Inadequate healing or malunion of the original fracture.
• Underlying conditions affecting bone strength, such as osteoporosis.
• Advanced age, which may contribute to reduced bone density or impaired healing.

Symptoms

• Chronic knee pain, especially with weight-bearing or movement.
• Persistent swelling or stiffness in the knee joint.
• Reduced range of motion, including difficulty straightening or bending the knee.
• Visible or palpable deformity of the kneecap.
• Instability or weakness in the knee during activity.

Diagnosis

Physical examination to assess knee alignment, stability, and functional limitations. Imaging tests, such as X-rays or CT scans, to evaluate the fracture's residual displacement and healing status. MRI may be used to assess soft tissue damage or associated joint conditions if clinically indicated.

Treatment Options

• Physical therapy: To improve strength, flexibility, and functional mobility.
• Pain management: Medications or injections to alleviate chronic discomfort.
• Surgical intervention: Considered for severe malalignment or persistent instability, potentially involving realignment or hardware removal.
• Assistive devices: Braces or supports to stabilize the knee during daily activities.

Prognosis and Follow-Up

Prognosis depends on the severity of residual displacement, patient age, and adherence to rehabilitation. Long-term follow-up may be necessary to monitor for arthritis, functional decline, or the need for further intervention. Most patients experience improved symptoms with appropriate management, though some may have persistent limitations.

Complications

• Post-traumatic arthritis due to joint damage.
• Chronic pain or stiffness.
• Reduced knee function or mobility.
• Increased risk of future knee injuries.

Lifestyle & Prevention

• Engage in low-impact exercises to maintain knee strength and flexibility.
• Use protective gear during high-risk activities to prevent re-injury.
• Maintain a healthy weight to reduce stress on the knee joint.
• Follow rehabilitation protocols to optimize recovery and minimize long-term effects.

When to Seek Professional Help

Seek medical attention if you experience worsening pain, new swelling, or a decrease in knee function. Prompt evaluation is recommended for signs of infection, severe instability, or sudden changes in mobility.

Tips for Medical Coders

Document the sequela status clearly, indicating the relationship to the prior displaced longitudinal fracture of the left patella. Ensure clinical notes specify the nature of the residual effects, such as chronic pain, malalignment, or functional impairment, to support accurate coding.
