[Lymphoma-induced imitation of knee prosthesis loosening].
Persistent pain after knee arthroplasty is often caused by aseptic loosening, implant failure, unphysiological alignment (especially of the patella), infection, scars and neuroma. In a case of a 70-year-old patient pain and swelling after knee arthroplasty persisted despite three revision procedures. Surprisingly, a non-Hodgkin's lymphoma was found in femoral bone marrow histology. A metastatic non-Hodgkin's lymphoma as cause of pain and swelling after knee arthroplasty, like in this case, is rare and has not been described up to now.
