Summary
Aneurysmal bone cysts are rare bone tumors. This case study details a rare instance of a patellar aneurysmal bone cyst, suggesting non-traumatic origins and successful surgical treatment.
Area of Science:
- Orthopedic Surgery
- Oncology
- Radiology
Background:
- Aneurysmal bone cysts (ABCs) are rare, benign bone lesions, comprising less than 1% of primary bone tumors.
- Patellar ABCs are exceptionally rare, with limited documented cases, particularly in specific demographic groups.
Observation:
- This report details the ninth known case of a primary aneurysmal bone cyst located in the patella.
- The patient is a white male, making this the second reported case in this demographic.
Findings:
- The rarity of patellar ABCs may challenge the hypothesis of trauma as a primary etiological factor.
- Successful treatment was achieved through curettage and bone grafting, provided the articular surface remained uninvolved.
Implications:
- Accurate diagnosis is crucial for effective management of patellar ABCs.
- This case contributes to the limited literature on patellar ABCs, aiding in understanding their presentation and treatment.
- Further research into the etiology of ABCs in unusual locations like the patella is warranted.
