Persistent Wound Drainage in Arthroplasty

Although persistent wound drainage (PWD) after total joint arthroplasty (TJA) is a relatively common and challenging problem, it is rarely reported. Therefore, there is little to no high-quality scientific evidence on many issues related to PWD after TJA, including the definition, risk factors and treatment of PWD. This lack of evidence results in wide variation in diagnosis and treatment in daily practice, often only founded on the surgeon’s opinion [1].
