Summary

Primary intra-articular sarcomas are rare knee tumors often missed due to vague symptoms. Early detection is crucial, as arthroscopy can complicate subsequent sarcoma treatment.

Area of Science:

  • Orthopedic Oncology
  • Musculoskeletal Pathology

Background:

  • Primary intra-articular sarcomas of the knee are rare malignancies.
  • Nonspecific symptoms like pain and swelling often lead to misdiagnosis or delayed diagnosis.

Observation:

  • This case series reviews four patients diagnosed with intra-articular sarcomas after undergoing diagnostic arthroscopy for non-oncologic reasons.
  • The identified sarcomas included two synovial sarcomas, one Ewing sarcoma of bone, and one osteosarcoma.

Findings:

  • Arthroscopic procedures for presumed benign conditions can complicate definitive sarcoma treatment.
  • Previous arthroscopies significantly altered surgical plans, necessitating extensive resections or limb-sparing surgeries like rotationplasty.

Implications:

  • Highlights the critical need to consider bone and soft-tissue sarcomas in the differential diagnosis for unexplained knee symptoms.
  • Emphasizes surgeon vigilance regarding clinical, physical, and imaging findings before arthroscopy to avoid diagnostic delays and treatment compromises.
