Background

The duration and extent of postoperative wound leakage after joint arthroplasty in patients with or without a complicated course, like a prosthetic joint infection (PJI), is currently unknown. Adequate differentiation between normal postoperative wound leakage and wound leakage due to a postoperative PJI is important and prevents unnecessary surgical procedures. We investigated the association between postoperative wound leakage and development of PJI in patients who used a previously developed mobile wound care app.

Methods

A multicenter, prospective cohort study with patients aged 18 years or older after primary implantation or revision of a total joint arthroplasty. During 30 post-operative days after arthroplasty, patients recorded their wound status in the woundcare app. An algorithm calculated a daily score from imputed data. If the daily score exceeded a predefined threshold, the patients received an alert that advised them to contact their physician.

Background

A lot of discussion persists whether obesity negatively influences the outcome of hip arthroplasty. Current literature does not answer this question, since manuscripts showing a worse outcome and those showing a similar outcome can both be found. We performed a meta-analysis with the primary research question whether obesity has a negative influence on short and long term outcome of total hip arthroplasty.

Methods

A search of the literature was performed and studies comparing the outcome of hip arthroplasty in different weight groups were included. Methodology of the included studies was scored according to the Cochrane guidelines. Data extraction and pooling of the data was performed. For continuous data a weighted mean difference and for dichotomous variables a weighted Odds ratio was calculated. Heterogeneity was calculated using I2 statistics.
