Differentiating quadriceps tendon and patellar tendon ruptures is crucial. Younger patients with patellar tendon rupture had good outcomes, while quadriceps tendon rupture outcomes varied, especially with delayed treatment.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Traumatology

Background:

  • Quadriceps tendon and patellar ligament ruptures are significant knee injuries.
  • Understanding the distinct mechanisms and patient demographics is essential for effective management.
  • Degenerative changes in older patients contrast with acute trauma in younger individuals.

Purpose of the Study:

  • To differentiate between quadriceps tendon ruptures and patellar ligament ruptures.
  • To analyze accident mechanisms, histology, comorbidities, treatment, and outcomes for both injury types.
  • To identify factors influencing patient recovery and functional knee status.

Main Methods:

  • Retrospective study of 17 patients (10 quadriceps tendon ruptures, 7 patellar ligament ruptures).

  • Clinical reexamination of all patients.
  • Review of accident mechanisms, histological findings, systemic/local diseases, therapy, and patient outcomes.

    • Main Results:

    • All patients with patellar ligament rupture demonstrated good outcomes.
    • Seven of ten patients with quadriceps tendon rupture also achieved good results.
    • Three patients with quadriceps tendon rupture experienced residual pain and limited knee function; two had delayed diagnosis/reconstruction, and one had a prosthetic joint infection.

    Conclusions:

    • Patellar ligament ruptures in younger patients typically result from considerable trauma and yield good results.
    • Quadriceps tendon ruptures in older patients often occur with trivial trauma due to tendon degeneration and have more variable outcomes.
    • Timely diagnosis and surgical reconstruction are critical for optimal outcomes in quadriceps tendon ruptures.
