This systematic review evaluates the efficacy and safety of blood flow restriction (BFR) training as a prehabilitation strategy for patients undergoing knee arthroplasty.

Researchers analyzed four randomized controlled trials to determine if combining low-load exercise with partial vascular occlusion could mitigate the severe muscle weakness typically observed after surgery.

Findings suggest that BFR training can significantly enhance early postoperative muscle strength and functional recovery compared to standard care without structured preoperative intervention.

The study highlights that BFR is a safe, well-tolerated alternative for elderly or frail populations who may struggle with traditional high-load resistance exercises.

While preliminary results are promising, the authors emphasize the need for larger, standardized trials to establish definitive clinical guidelines.

Ultimately, the source positions BFR prehabilitation as a potential tool to accelerate recovery and reduce long-term healthcare utilization.
