Functional somatic syndromes linked to inferior outcomes and increased complications after hip and knee arthroplasty: study

Key findings of the study were:

• There were twenty-eight studies, including 768,909 patients, of which 378,384 had an FSS.

• Five studies reported preoperative PROMs prior to THA/TKA, all of which showed worse PROMs among patients with at least 1 FSS diagnosis.

• Thirteen studies reported postoperative PROMs after THA/TKA, all of which demonstrated worse PROMs among patients with at least 1 FSS diagnosis.

• Patients with FSS diagnoses were more likely to continue using opioids at 3, 6, and 12 months following TKA, THA, and UKA.

• Medical and surgical complications, as well as revision rates, were higher among patients with FSSs.

The authors concluded that – “Patients with FSSs have inferior PROMs and are at increased risk for prolonged postoperative opioid use, medical and surgical complications, and revision after hip and knee arthroplasty. Improved understanding of the factors influencing the success of hip and knee arthroplasty is critical. Future studies should address the biopsychosocial determinants of health that can impact outcomes after total joint arthroplasty.”
