Bilateral total knee arthroplasty with modified primary components in the management of neuropathic arthropathy related to chronic pancreatitis: a case with 5-year follow-up

Although neuropathic arthropathy of the foot and ankle joints in diabetes is well known, the involvement of the knee joint is rare. Then, the management, particularly the use of arthroplasty, is a matter of debate. We report a 51-year-old man with neuroarthropathic involvement of both knees related to the chronic pancreatitis treated by modified primary total knee arthroplasty components using augments and extension stems only on the tibial side. Our 5-year observations revealed that although the replacement surgery in neuroarthropathy is associated with high rate of complications, it is highly effective in avoiding progressive functional disability and durable.
