The Association Between Lower Extremity Continuous Peripheral Nerve Blocks and Patient Falls After Knee and Hip Arthroplasty

In Brief BACKGROUND: Continuous peripheral nerve blocks (CPNB) may induce muscle weakness, and multiple recently published series emphasize patient falls after postarthroplasty CPNB. However, none have included an adequate control group, and therefore the relationship between CPNB and falls remains speculative. METHODS: We pooled data from 3 previously published, randomized, triple-masked, placebo-controlled studies of CPNB involving the femoral...
