Primary patellar tumors are rare, with most benign cases manageable. Malignant tumors, often linked to Rothmund-Thomson syndrome, present significant surgical challenges for limb and extensor mechanism preservation.

Area of Science:

  • Orthopedic Oncology
  • Surgical Pathology
  • Bone Tumor Research

Background:

  • Primary tumors of the patella are uncommon in orthopedic oncology.
  • Surgical management of patellar tumors requires careful consideration of tumor type and extent.
  • Benign and malignant patellar neoplasms have distinct clinical behaviors and treatment implications.

Purpose of the Study:

  • To analyze the incidence and characteristics of primary patellar tumors in a surgical cohort.
  • To evaluate treatment outcomes and surgical challenges associated with patellar neoplasms.
  • To highlight the importance of accurate diagnosis and tailored surgical strategies for patellar tumors.

Main Methods:

  • Retrospective review of 587 patients undergoing surgery for bone tumors.

  • Identification and classification of primary patellar tumors based on histology.
  • Analysis of patient demographics, tumor types, treatment modalities, and outcomes.

    • Main Results:

    • Eight primary patellar tumors identified (6 benign: 5 giant cell tumors, 1 chondroblastoma; 2 malignant: osteosarcoma, malignant fibrous histiocytoma).
    • Both malignant cases occurred in patients with Rothmund-Thomson syndrome.
    • Benign pulmonary metastases observed in 2 giant cell tumor patients; one patient deceased at 72 months.
    • Suboptimal initial treatment (patellectomy without diagnosis, curettage) led to disease extension into the knee joint.

    Conclusions:

    • Patellar tumors necessitate meticulous preoperative assessment and individualized surgical planning.
    • Bone conservation is feasible for benign lesions with sufficient articular surface remaining.
    • Limb salvage for malignant patellar tumors is possible, but extensor mechanism reconstruction remains a significant challenge.
