IPICK Blocking for TKA With Moderate Flexion Contracture

The First Hospital of Jilin University42 enrolled

Overview

Clinical effect of intermittent multiple IPICK blocking on TKA for knee osteoarthritis with flexion contracture between 5 ° and 10 °

From October 2020 to January 2021, 40 knee osteoarthritis patients with flexion contracture between 5 ° and 10 ° total knee arthroplasty are enrolled in this study. 20 patients are treated with Adductor Canal Block + Infiltration between the Popliteal Artery and Capsule of the Knee, and 20 patients are treated with Adductor Canal Block alone.
