S82.014S Nondisplaced osteochondral fracture of right patella, sequela

Name of the Condition

• Nondisplaced osteochondral fracture of right patella, sequela

Summary

This condition represents the residual effects of a previous nondisplaced osteochondral fracture of the right patella (kneecap). The term "sequela" indicates that the injury has healed, but ongoing consequences such as chronic pain, limited mobility, or cartilage damage persist. The fracture involved both bone and cartilage, and the nondisplaced nature means the fragments remained in their original position during the initial injury.

Causes

The sequela arises from a prior injury to the right patella, typically caused by direct trauma such as a fall onto the kneecap, a forceful blow, or a high-impact event (e.g., sports injury or motor vehicle accident). The initial fracture damaged both the bone and overlying cartilage without displacing the fragments, leading to long-term effects as the injury heals.

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 and impair healing.

Symptoms

• Chronic pain in the right knee, often worsened by activity.
• Swelling or stiffness around the kneecap.
• Difficulty straightening or bearing weight on the right knee.
• Reduced range of motion in the knee joint.
• Occasional "popping" or grinding sensations during movement.

Diagnosis

A physical examination to assess knee movement, swelling, and tenderness. Imaging studies, typically X-rays or MRI, to evaluate residual bone or cartilage damage. The diagnosis confirms the sequela by linking current symptoms to a prior fracture, with no active fracture present.

Treatment Options

• Physical therapy to improve strength and mobility.
• Pain management with medications or injections.
• Assistive devices (e.g., braces) to support the knee during activity.
• Surgical intervention if severe cartilage damage or persistent instability occurs.

Prognosis and Follow-Up

Most patients experience gradual improvement with conservative management, though some may have lasting limitations. Regular follow-up appointments monitor symptoms and adjust treatment as needed. Prognosis depends on the extent of initial injury and adherence to rehabilitation.

Complications

• Chronic knee pain or arthritis.
• Persistent swelling or stiffness.
• Reduced ability to perform daily activities or sports.
• Need for additional surgery if complications arise.

Lifestyle & Prevention

• Avoid high-impact activities that stress the knee.
• Maintain a healthy weight to reduce joint strain.
• Use proper protective gear during sports.
• Engage in low-impact exercises (e.g., swimming) to support knee health.

When to Seek Professional Help

Seek care if symptoms worsen, new pain develops, or mobility significantly declines. Prompt evaluation is important if swelling, redness, or fever occurs, as these may indicate infection or other issues.

Tips for Medical Coders

Document the sequela clearly, noting the prior fracture and current residual effects. Ensure the code S82.014S is used only when the condition represents a late effect of the initial injury, with no active fracture present. Include details on the nature of the sequela (e.g., chronic pain, mobility issues) to support coding accuracy.
