ABSTRACT

Diagnosis: Metallosis secondary to loosening of metallic back of patellar prosthesis of total knee arthroplasty, confirmed intraoperatively during arthroplasty revision.

History: Knee pain and decreased range of motion status-post total knee arthroplasty

Findings: Image 1: Lateral view of the right knee from Jan, 2003: total knee arthroplasty with radiopaque material in the joint, predominantly in the patellofemoral component. Metallic back of the patellar prosthesis is loosened and is located inferior to patella. Image 2: Lateral view of the right knee from Aug, 2001: total knee arthroplasty with no evidence of complication. Note the normal location of the metallic back of the patellar prosthesis.

Ddx: - Arthroplasty failure with metallosis - Other foreign body - Hemarthrosis with dystrophic calcification - Chondrocalcinosis

Exam: N/A

No MeSH data available.


Patient had total knee arthroplasty without evidence of complication.  Note the proper location of the metal-backed patellar component.
