A meta-analysis of 12 studies indicates there is no evidence to suggest that patient weight fluctuates following total joint arthroplasty.
“We found no conclusive evidence that weight or body composition increases, decreases or remains the same after total joint arthroplasty,” Maria C. S. Inacio, MS, and colleagues wrote in their study.
Of the 12 studies included in the review, five included both total hip and knee arthroplasty cases; four studies were solely comprised of total hip cases and three studies had all total knee cases. Most studies were single-surgeon or single-center studies, according to the abstract.
The investigators found that most studies reported 14% to 49% weight loss 1-year postoperatively, according to the abstract. However, after analyzing the studies for several factors including procedure type, inclusion criteria, level of evidence, study type, number of patients who fluctuated in weight as well as the time of composition assessment, the investigators concluded that the studies had serious limitations and highlighted their observational nature.
