SSSI Efficacy With iACB and PC-LIA in TKA Pain Management

NCT07191964

This prospective, triple-blinded, sham-controlled randomized trial evaluates the additive effect of Supra-Sartorial Subcutaneous Infiltration (SSSI) combined with intermittent adductor canal block (iACB) and posterior capsule local infiltration analgesia (PC-LIA) for pain management in total knee arthroplasty (TKA). SSSI, a simpler alternative to targeted anterior femoral cutaneous nerve (AFCN) block, is tested in 90 adults (45-90 years) randomized into two arms: sham SSSI + active iACB + PC-LIA versus all active interventions. Primary outcome is pain scores on postoperative day 0; secondary outcomes include daily pain trajectory, opioid use, functional recovery, and complications over days 0-3.
