S82.015S Nondisplaced osteochondral fracture of left patella, sequela

Name of the Condition

• Nondisplaced osteochondral fracture of left patella, sequela

Summary

This condition represents the long-term effects of a previous nondisplaced osteochondral fracture of the left patella (kneecap). The injury involves damage to both the bone and its attached cartilage, with the fragment remaining in its original anatomical position. The "sequela" designation indicates that the condition is a residual effect following the acute phase of the injury, rather than an active fracture.

Causes

The sequela arises from a prior nondisplaced osteochondral fracture of the left patella, typically resulting from direct trauma to the knee. The original injury may have been caused by a fall onto the kneecap, a forceful blow, or a high-impact event such as a motor vehicle accident or sports injury. The sequela develops as a result of the body’s healing response to the initial fracture.

Risk Factors

• History of prior knee trauma or fracture.
• Inadequate initial treatment or healing of the original injury.
• Underlying conditions affecting bone or cartilage health (e.g., osteoporosis).
• Participation in activities that stress the knee joint.

Symptoms

• Chronic knee pain, particularly with movement or weight-bearing.
• Swelling or stiffness in the left knee.
• Reduced range of motion or difficulty fully straightening the knee.
• Occasional clicking or catching sensations in the joint.
• Persistent tenderness around the kneecap.

Diagnosis

A physical examination to assess knee function, stability, and tenderness. Imaging studies, such as X-rays, to evaluate bone alignment and signs of previous fracture. MRI may be used to assess cartilage integrity or residual damage. Clinical correlation with the patient’s history of prior injury is essential for diagnosis.

Treatment Options

Treatment focuses on managing symptoms and improving function. Options may include physical therapy to strengthen surrounding muscles and improve mobility, pain management with medications or injections, and activity modification to reduce joint stress. In some cases, surgical intervention may be considered to address persistent symptoms or structural issues.

Prognosis and Follow-Up

Prognosis varies depending on the extent of residual damage and adherence to treatment. Most patients experience improvement in symptoms with appropriate management, though some may have long-term limitations in knee function. Regular follow-up with a healthcare provider is recommended to monitor progress and adjust treatment as needed.

Complications

• Chronic knee pain or instability.
• Post-traumatic arthritis due to cartilage damage.
• Reduced mobility or difficulty with daily activities.
• Need for further intervention if symptoms persist.

Lifestyle & Prevention

• Engage in low-impact exercises to maintain knee strength and flexibility.
• Use proper protective gear during activities with a risk of knee injury.
• Avoid sudden, high-impact movements that stress the knee joint.
• Maintain a healthy weight to reduce joint load.

When to Seek Professional Help

Seek medical attention if you experience worsening knee pain, swelling, or difficulty bearing weight, or if symptoms do not improve with conservative management. Prompt evaluation is important to address any new or progressive issues.

Tips for Medical Coders

This code is used for the sequela of a nondisplaced osteochondral fracture of the left patella. Documentation should clearly indicate the relationship to the prior injury, including the nature of the residual effects (e.g., chronic pain, limited mobility) and any ongoing treatment. Ensure the code is assigned only when the condition is a direct result of the original fracture and not an active, acute injury.
