Hip replacement analysis of periprosthetic tissue at ×400 magnification. None of the above laboratory tests has 100% sensitivity or specificity for diagnosing infection. Specificity improves when the tests are performed in patients in whom clinical suspicion exists. ESR and CRP remain good 1st line tests for screening (high sensitivity, low specificity). Aspiration of the joint remains the test with the highest specificity for confirming infection. Dislocation is the most common complication of hip replacement surgery. The most common causes vary by the duration since the surgery. Hip prosthesis dislocation mostly occurs in the first 3 months after insertion, mainly because of incomplete
