Patient Presentation:
A 28-year-old female professional soccer athlete presented approximately 6 months after right anterior cruciate ligament (ACL) reconstruction with bone-patellar tendon-bone (BTB) patellar tendon autograft, internal brace augmentation, and lateral meniscus repair. She reported two concurrent concerns: new-onset anterior knee pain and a recent enlargement of a long-standing pigmented lesion on the ipsilateral thigh.
History:
The patient initially had an uncomplicated postoperative course following ACL reconstruction. Approximately 6 months postoperatively, she developed atraumatic, insidious onset of sharp pain localized to the proximal patella during rehabilitation. Symptoms were exacerbated by resisted knee extension.
Concurrently, she reported recent enlargement of a long-standing mole on her right anterior thigh, raising concern after her teammates commented on it. She denied systemic symptoms or family history of skin malignancy.
Physical Exam:
Right knee exam
Full Range of Motion and strength. Pain with resisted knee extension. Surgical scar well-healed. Point tenderness at the inferior pole of the patella/proximal patellar tendon at the Bone tendon Bone harvest site.
