Double patella, a rare knee condition from repetitive extensor mechanism injuries, involves tendon avulsion and subsequent ossification. Surgical intervention removes calcification and reattaches the tendon for treatment.

Area of Science:

  • Orthopedics
  • Sports Medicine
  • Traumatology

Background:

  • Double patella is an uncommon condition resulting from repetitive knee extensor mechanism injuries.
  • It originates from tendo-periosteal avulsion of the patellar tendon, often misdiagnosed and inadequately treated.
  • Recurrent instability leads to ossification, creating a "double patella" appearance.

Purpose of the Study:

  • To describe the pathophysiology and clinical presentation of double patella.
  • To highlight diagnostic challenges and treatment outcomes for this rare condition.

Main Methods:

  • Review of clinical cases and literature on double patella.
  • Description of the injury mechanism, including avulsion and ossification.
  • Outline of the surgical approach for treatment.

Main Results:

  • The condition involves initial tendon avulsion followed by ossification due to instability.
  • Misdiagnosis and conservative treatment often precede the development of the characteristic double patella.
  • Surgical treatment involves removing ossification and repairing the tendon.

Conclusions:

  • Double patella is a distinct entity arising from specific knee injuries and instability.
  • Accurate diagnosis and appropriate surgical management are crucial for effective treatment.
  • Surgical repair offers a definitive solution for symptomatic double patella.
