S82.031S Displaced transverse fracture of right patella, sequela

Name of the Condition

• Displaced transverse fracture of right patella, sequela

Summary

This condition represents a sequela (late effect) of a previously sustained displaced transverse fracture of the right patella. The term "sequela" indicates that the condition is a residual or chronic consequence of the initial injury, rather than an acute event. The fracture involves a horizontal break in the right kneecap with bone fragments that remain displaced, and the sequela status implies ongoing effects such as persistent pain, functional impairment, or other long-term complications.

Causes

The sequela arises from a prior displaced transverse fracture of the right patella, typically caused by direct trauma to the knee (e.g., falls, blows, or forceful muscle contractions). The initial injury may have been managed, but residual effects persist, leading to the sequela classification.

Risk Factors

• Prior history of patellar fracture or knee trauma.
• Inadequate initial treatment or healing of the fracture.
• Underlying conditions affecting bone or soft tissue recovery (e.g., osteoporosis, poor circulation).
• Advanced age, which may impair healing and increase susceptibility to chronic effects.

Symptoms

• Chronic or recurrent pain in the right knee, especially with movement.
• Persistent swelling or stiffness around the kneecap.
• Reduced range of motion or difficulty bearing weight on the right leg.
• Visible or palpable deformity in the patella area.
• Functional limitations, such as difficulty climbing stairs or kneeling.

Diagnosis

A clinical evaluation focusing on the history of the prior fracture and current symptoms. Imaging studies (e.g., X-rays) may be used to assess residual displacement, bone healing, or associated degenerative changes. Physical examination assesses knee stability, range of motion, and signs of chronic inflammation or instability.

Treatment Options

Management depends on the severity of residual symptoms and functional impairment. Options may include:

• Physical therapy to improve strength and mobility.
• Pain management (e.g., NSAIDs, corticosteroid injections).
• Orthotic devices or bracing for support.
• Surgical intervention (e.g., hardware removal, realignment) if significant deformity or instability persists.
• Lifestyle modifications to avoid aggravating activities.

Prognosis and Follow-Up

Prognosis varies based on the extent of residual damage and adherence to treatment. Chronic pain or functional limitations may persist, but most patients achieve improved quality of life with appropriate management. Regular follow-up is recommended to monitor for worsening symptoms or complications.

Complications

• Chronic knee pain or arthritis.
• Persistent instability or weakness.
• Reduced mobility or disability.
• Need for additional interventions (e.g., surgery) if symptoms progress.

Lifestyle & Prevention

• Engage in low-impact exercises to maintain knee strength without stressing the joint.
• Use protective gear during activities with fall risks.
• Maintain a healthy weight to reduce knee strain.
• Follow post-injury rehabilitation protocols to minimize long-term effects.

When to Seek Professional Help

Seek care if symptoms worsen, new pain or swelling develops, or functional limitations interfere with daily activities. Prompt evaluation is important to address complications or adjust treatment.

Tips for Medical Coders

Document the history of the prior displaced transverse fracture of the right patella and confirm the sequela status. Ensure clinical notes specify the residual effects (e.g., chronic pain, functional impairment) to support the sequela code. Verify that the code aligns with the timing of the encounter (sequela) and the affected side (right patella).
