Implication

Case report reveals quadriceps tendon rupture in a patient with undiagnosed alkaptonuria, suggesting important diagnostic implications.

Key Points

  • This case report aims to illustrate quadriceps tendon rupture as an initial presentation of undiagnosed alkaptonuria.
  • Documented a rare case of a 49-year-old man with a quadriceps tendon rupture after minor trauma.
  • Used magnetic resonance imaging to confirm the injury and assess tendon damage.
  • Conducted surgical repair with transosseous sutures and observed intraoperative pigment changes.
  • Confirmed complete quadriceps tendon rupture via MRI and noted tendon pigmentation consistent with ochronosis.
  • Achieved functional recovery and full knee extension post-surgery.
  • Identified additional signs of alkaptonuria, including urine discoloration and spinal disc calcification.
