[Obesity in Revision Total Knee Arthroplasty - a Systematic Review and Legal Assessment].

DISCUSSION: Five studies met the inclusion criteria and were included in the systematic review. The average Jadad score was 1, the average level of evidence 3. In two studies, infection and revision occured more often in obese patients. Patients with morbid obesity had a higher risk of wound revision and periprosthetic joint infections. Three studies showed that obese patients had significantly lower scores for clinical outcome measures in function and pain. The legal aspect was not discussed in any of the five studies. Overall, published data are sparse and very heterogeneous. Therefore comparing these five studies is difficult. However, the results of our review suggest that obesity in revision total knee arthroplasty may have a negative influence on reoperation rate, infection rate and postoperative functional outcome. From a legal point of view, potential weight limitations of the implants intented for use have to be part of the oral preoperative discussion. The patient's informed consent has to be received and documented prior to revision total joint arthroplasty. PMID: 29669384 [PubMed - as supplied by publisher]
