Rash After Anterior Cruciate Ligament Reconstruction

Rash After Anterior Cruciate Ligament Reconstruction


A healthy 35-year-old man sustained a complete anterior cruciate ligament (ACL) tear of his right knee while playing soccer and underwent an uncomplicated ACL reconstruction with a bone-patella tendon-bone autograft. During his first postoperative week, a nonpruritic rash

developed around the surgical incision (photograph). He was concerned about infection.

The patient had minimal pain, moderate soft tissue swelling, and no postoperative fever. On physical examination, there was a mild effusion, mild diffuse tenderness, and painless range of motion (0° to 85°). The skin lesions were erythematous, patchy, and nonelevated. The rash was well localized and did not extend above midthigh or below midcalf. There was no lymphadenopathy or drainage from the incision. The patient's neurovascular status was normal. Plain radiographs revealed no abnormalities. No laboratory values were obtained.
