Clinical Trial Summary

A double-blind, randomized controlled trial designed to evaluate the symptomatic modulating efficacy of amniotic suspension allograft (ASA) in comparison to platelet-rich plasma (PRP), hyaluronic acid (HA) and normal saline (NS) in the injection treatment of knee osteoarthritis. The hypothesis is that ASA would provide the greatest functional improvement.

Description:

At least 150 subjects with osteoarthritic knee will be recruited and computer randomized 1:1:1:1 to single injection of ASA (40mg), ASA (20mg), PRP + HA, and NS groups. Both subjects and evaluaters were blinded to allocations. Functional and radiologic outcomes were measured at baseline, and 1 week, 1, 3, 6, 12 months postinjection.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change of the Western Ontario and McMaster Universities Arthritis Index (WOMAC) between baseline, 1 week, and 1 ,3 ,6 ,12 months.	WOMAC is a self-administered questionnaire consisting of 24 items divided into 3 subscales:(1) Pain (5 items): during walking, using stairs, in bed, sitting or lying, and standing upright(2) Stiffness (2 items): after first waking and later in the day(3) Physical Function (17 items): using stairs, rising from sitting, standing, bending, walking, getting in / out of a car, shopping, putting on / taking off socks, rising from bed, lying in bed, getting in / out of bath, sitting, getting on / off toilet, heavy domestic duties, light domestic dutiesThe test questions are scored on a scale of 0-4, which correspond to: None (0), Mild (1), Moderate (2), Severe (3), and Extreme (4).	Baseline, 1 week, 1,3,6,12 months
Secondary	Change of the International Knee Documentation Committee (IKDC Questionnaire) between baseline, 1 week, and 1 ,3 ,6 ,12 months.	The International Knee Documentation Committee Questionnaire is a knee-specific patient-reported outcome measure.The questionnaire looks at 3 categories: symptoms, sports activity, and knee function. The symptoms subscale helps to evaluate things such as pain, stiffness, swelling and giving-way of the knee. Meanwhile, the sports activity subscale focuses on functions like going up and down the stairs, rising from a chair, squatting and jumping. The knee function subscale asks patients one simple question: how is their knee at present versus how was their knee prior to injury? Scores are obtained by summing the individual items, then transforming the crude total to a scaled number that ranges from 0 to 100, This final number is interpreted as a measure of function with higher scores representing higher levels of function.	Baseline, 1 week, 1,3,6,12 months
