S82.036S Nondisplaced transverse fracture of unspecified patella, sequela

Name of the Condition

• Nondisplaced transverse fracture of unspecified patella, sequela

Summary

This condition represents a healed or residual state of a previously nondisplaced transverse fracture of the patella (kneecap). The fracture line runs horizontally across the bone, and the bone fragments remain aligned. The term "sequela" indicates this is a chronic or long-term consequence of the original injury, with no active fracture present. The patella, a triangular bone protecting the knee joint, may show signs of prior healing, such as callus formation or altered bone structure, but the fracture is no longer acute.

Causes

The sequela arises from a prior nondisplaced transverse fracture of the patella, typically caused by direct trauma to the knee (e.g., falls, blows, or forceful muscle contractions). The original injury may have resulted from high-impact events like sports injuries or motor vehicle accidents. The current state reflects the body’s healing response over time, with residual changes from the initial fracture.

Risk Factors

• Prior history of patellar fracture or knee trauma.
• Activities or occupations involving repetitive knee stress.
• Underlying bone conditions (e.g., osteoporosis) that may have contributed to the original fracture.
• Advanced age, which can affect bone healing and residual structural changes.

Symptoms

• Chronic knee pain or discomfort, often localized to the patella.
• Mild swelling or stiffness, particularly with activity.
• Reduced range of motion or difficulty fully extending the knee.
• Visible or palpable bony prominence or irregularity in the patella area.
• Occasional instability or a feeling of the knee "giving way."

Diagnosis

A physical examination to assess knee function, tenderness, and structural changes. Imaging studies, such as X-rays, to evaluate residual bone alignment and healing. CT or MRI may be used to assess soft tissue or cartilage damage from the original injury. Clinical history confirming a prior patellar fracture is essential for diagnosis.

Treatment Options

• Conservative management: Physical therapy to strengthen surrounding muscles and improve mobility.
• Pain relief: NSAIDs or other medications to manage chronic discomfort.
• Orthopedic evaluation: For persistent symptoms or functional limitations, to assess the need for further intervention (e.g., bracing or surgery).
• Activity modification: Avoiding high-impact activities to reduce stress on the knee.

Prognosis and Follow-Up

Most patients experience improved function with conservative care, though some residual symptoms may persist. Follow-up imaging or clinical visits may be recommended to monitor healing or address ongoing issues. Long-term outcomes depend on the severity of the original injury and adherence to rehabilitation.

Complications

• Chronic knee pain or arthritis due to altered joint mechanics.
• Reduced mobility or persistent stiffness.
• Risk of re-injury if the knee is not properly supported.
• Rarely, surgical intervention may be needed for severe residual deformity.

Lifestyle & Prevention

• Strengthening exercises for the quadriceps and hamstrings to support the knee.
• Using proper footwear and protective gear during high-risk activities.
• Maintaining bone health through diet and exercise to reduce fracture risk.
• Avoiding repetitive stress on the knee (e.g., excessive kneeling or jumping).

When to Seek Professional Help

• Worsening pain, swelling, or instability in the knee.
• Inability to bear weight or perform daily activities.
• Signs of infection (e.g., redness, warmth, or fever) at the injury site.
• Sudden changes in knee function or new deformity.

Tips for Medical Coders

This code (S82.036S) is used for a sequela of a nondisplaced transverse patellar fracture. Documentation must confirm the prior fracture and its chronic nature, with no active fracture present. Ensure the record specifies "sequela" and links the current condition to the original injury. Avoid using this code for acute fractures or initial encounters.
