Abstract
- A female patient who underwent total knee arthroplasty presented with a snapping sensation over the left knee at 10 years postoperatively. Initially, the bony mass was visible on the medial femoral condyle radiographically at 5 years postoperatively. The mass had enlarged over time and her symptoms were progressive. The mass was excised at postoperative 18 years and confirmed as an osteochondroma histopathologically. The patient's symptoms have been completely resolved for 3-year follow-up after excision. LEVEL OF EVIDENCE: V
