S82.035S Nondisplaced transverse fracture of left patella, sequela

Name of the Condition

• Nondisplaced transverse fracture of left patella, sequela

Summary

This condition represents a healed or healing horizontal break across the left kneecap (patella), where the bone fragments remain aligned without displacement. The term "sequela" indicates this is a residual effect or complication following the initial fracture, such as chronic pain, limited mobility, or other long-term consequences of the injury.

Causes

The sequela arises from a prior nondisplaced transverse fracture of the left patella, typically resulting from direct trauma to the knee (e.g., falls, blows, or forceful muscle contractions). The residual effects develop as the fracture heals, potentially due to incomplete recovery, underlying bone weakness, or inadequate rehabilitation.

Risk Factors

• Prior history of patellar fracture or knee injury.
• Osteoporosis or reduced bone density, which may impair healing.
• Inadequate or delayed treatment of the initial fracture.
• Advanced age, which can slow recovery and increase susceptibility to chronic effects.

Symptoms

• Persistent pain in the left knee, especially with movement or weight-bearing.
• Stiffness or reduced range of motion in the knee joint.
• Swelling or tenderness around the kneecap.
• Difficulty fully straightening or bending the knee.
• Possible audible clicking or grinding (crepitus) during movement.

Diagnosis

A physical examination to assess knee function, pain patterns, and residual swelling. Imaging studies, such as X-rays or MRI, to evaluate bone healing and identify any persistent misalignment or degenerative changes. Clinical correlation with the patient’s history of the initial fracture is essential to confirm the sequela.

Treatment Options

Management focuses on alleviating symptoms and improving function. Options may include physical therapy to strengthen surrounding muscles and restore mobility, pain-relieving medications, or assistive devices (e.g., braces) to support the knee. In severe cases, surgical intervention to address residual deformity or instability may be considered.

Prognosis and Follow-Up

Prognosis depends on the extent of the initial injury and adherence to rehabilitation. Most patients experience gradual improvement, but some may have permanent limitations. Regular follow-up with a healthcare provider is recommended to monitor healing and adjust treatment as needed.

Complications

• Chronic knee pain or arthritis.
• Persistent stiffness or reduced mobility.
• Risk of re-injury due to weakened bone or muscle imbalances.
• Nerve or tissue damage from the original trauma.

Lifestyle & Prevention

• Engage in low-impact exercises (e.g., swimming, cycling) to maintain knee strength without stress.
• Use proper protective gear during high-risk activities (e.g., sports, work).
• Maintain bone health through a balanced diet and weight management.
• Follow post-fracture rehabilitation protocols to minimize long-term effects.

When to Seek Professional Help

Seek care if symptoms worsen, new pain or swelling develops, or mobility significantly declines. Prompt evaluation is necessary to rule out new injuries or complications.

Tips for Medical Coders

Document the sequela clearly, linking it to the prior fracture. Ensure the record specifies the residual effects (e.g., chronic pain, limited function) and confirms the fracture is healed or healing. Use this code only when the condition is a direct result of the initial injury and not an active fracture.
