Brief summary

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

Detailed description

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.

Design outcomes

Primary

Measure	Time frame	Description
evaluation of pain	6 hours after surgery	Visual Analog Score for pain at rest, straightening, flexion at 45 ° and walking, the minimum and maximum values are 0 to 10, higher scores mean a worse outcome.
extension angle	before surgery	degree of the extension of knee

Secondary

Measure	Time frame	Description
range of motion	6 hour after surgery	degree of range of motion from extension to flexion of knee
opioid consumption	through hospitalization, an average of 7 days	total opioid consumption measured by milliliter.
nerve block related symptoms	through hospitalization, an average of 7 days	the incidence of numbness of the nerve related skin
postoperative acute pain	through hospitalization, an average of 7 days	number of cases whose Visual Analog Score for pain was more than 5
