Summary

Caveat arthroscopy, a rare surgical event, involves treating unexpected extra-articular neoplasms during procedures for nonneoplastic intra-articular disease. Avoiding prereferral biopsies of suspected neoplasms is key to preventing complications.

Area of Science:

  • Orthopedic Surgery
  • Oncology
  • Diagnostic Imaging

Background:

  • Arthroscopy is typically used for intra-articular conditions.
  • Unexpectedly encountering and managing extra-articular neoplasms during arthroscopy is termed caveat arthroscopy.
  • This phenomenon represents a maloccurrence, not negligence.

Purpose of the Study:

  • To define and illustrate caveat arthroscopy.
  • To analyze the consequences of this surgical event.
  • To propose preventative strategies.

Main Methods:

  • Retrospective review of 13 cases of caveat arthroscopy over a 6-year period.
  • Analysis of diagnoses, including soft tissue sarcomas, benign bone tumors, skeletal sarcomas, and benign soft tissue tumors.
  • Examination of complications associated with prereferral biopsies.

Main Results:

  • The majority of cases (12/13) involved the knee.
  • All cases experienced complications due to prereferral biopsies.
  • Complications included compartment contamination, inaccurate diagnoses, and diagnostic delays.

Conclusions:

  • Caveat arthroscopy is associated with significant complications, primarily stemming from prereferral biopsies.
  • Adequate imaging of suspected neoplasms is crucial.
  • Referral to a tertiary institution before biopsy is recommended to prevent adverse outcomes.
