Severe joint pain with sarcoidosis is relatively rare. Arthroplasty is used to treat degenerative joint disease from sarcoidosis. Sarcoidosis or chronic granulomatous disease has been noted to be a rare side effect of arthroplasty as well, particularly with metal on metal implants or catastrophic failure of implants. This is similar to the issues with leaking silicone breast implants. Sarcoidosis as a comorbidity while having a revision TSA is uncommon and no specific study addresses any known complications. It may affect how well you tolerate anesthesia more so than healing the surgery, if you have granulomatous formation in the lungs. It will likely affect your immune response to the surgical insult, but your infection risk is not likely to be greatly affected due to the fact that you would still develop an appropriate white blood cell response to any bacterial challenge. Depending upon how the TSA has failed, I am not sure you would have much of an option besides revision arthroplasty and would have to accept the surgical risk.
