Massive bilateral prepatellar bursitis developed in a man with cerebral palsy due to repetitive injury from ambulation. This protective bursal cushioning allowed for functional, painless mobility despite knee contractures.

Area of Science:

  • Orthopedics
  • Neurology
  • Rehabilitation Medicine

Background:

  • Cerebral palsy (CP) can lead to motor impairments and musculoskeletal complications.
  • Fixed knee flexion contractures are common in individuals with CP, impacting mobility.
  • Repetitive stress injuries can occur in individuals with gait abnormalities.

Observation:

  • A 36-year-old African American male with cerebral palsy presented with bilateral, slowly enlarging knee masses.
  • The patient had 90-degree fixed flexion knee contractures bilaterally.
  • Despite communication difficulties, he ambulated without reported discomfort.

Findings:

  • Massive bilateral prepatellar bursitis was diagnosed, attributed to chronic, repetitive injury during ambulation.
  • The enlarged bursae served as a protective cushion over the tibial tubercle and patella.

  • This compensatory mechanism facilitated functional, painless household ambulation.

    • Implications:

    • Prepatellar bursitis can be a compensatory adaptation in individuals with CP and knee contractures.
    • Understanding these adaptations is crucial for managing mobility and preventing further injury.
    • This case highlights the body's ability to adapt to functional limitations through protective mechanisms.
