The relation between postoperative wound leakage and occurrence of a prosthetic joint infection (PJI) after arthroplasty has not been investigated in a prospective study. We performed a large cohort study in which 1019 patients, after arthroplasty, recorded their wound drainage status in a wound care app during 30 postoperative days. Risk factors for wound drainage were identified. Moderate to heavy wound leakage in the third postoperative week was strongly associated with the occurrence of PJI.

A Madura foot caused by the fungus Madurella mycetomatis is a rare condition in non-endemic countries, but should be included in the differential diagnosis in case of soft tissue swellings of the foot in patients who have been in mycetomatis-endemic regions, more specifically in immunocompromised patients, who are at risk of developing a (more severe) mycetoma infection. Adequate treatment is needed to prevent the progression and recurrence of a Madura foot.
