Systematic review and meta-analysis shows prior bariatric surgery does not affect revision rates after total knee arthroplasty, indicating a need for prospective studies.
Our pooled analysis showed that prior bariatric surgery did not significantly impact revision rates after TKA. However, no change in BMI status after BS was recorded. Future research should prioritise prospective studies and long-term registry follow-up with detailed nutritional and clinical data to clarify the role of BS as a pre-arthroplasty optimisation strategy.
