This case study highlights a rare instance of patellar chondrosarcoma in a 68-year-old woman. Surgical resection led to a full recovery with no recurrence, emphasizing the importance of recognizing this rare bone tumor.
Area of Science:
- Orthopedic Oncology
- Skeletal Radiology
- Pathology
Background:
- Chondrosarcoma, a malignant bone tumor producing cartilage matrix, typically affects long bones and pelvis, representing 20-27% of malignant bone tumors.
- Patellar chondrosarcoma is exceptionally rare, posing diagnostic and therapeutic challenges.
Observation:
- A 68-year-old woman presented with a six-month history of painful swelling and limited motion in her right knee, exhibiting redness, heat, and a claudicating gait.
- Imaging revealed irregular, ill-defined lytic lesions in the patella, confirmed as primary grade II chondrosarcoma post-operatively.
Findings:
- The patient underwent successful extensive resection of the patellar tumor.
- Post-surgery, she experienced complete pain relief, restored knee function, and normal gait within three months, with no signs of recurrence.
Implications:
- Extensive resection is a viable surgical approach for patellar chondrosarcoma, potentially minimizing local recurrence.
- Increased awareness among orthopedic surgeons and radiologists regarding patellar chondrosarcoma is crucial for timely diagnosis and management of this rare condition.
