Last Updated: 2021-10-18

Results Overview

Outcome Measures in Rheumatology Clinical Trials- Osteoarthritis Research Society International (OMERACT-OARSI) Response incorporates changes in pain and global assessment to define response in OA clinical trials. A response is classified as: 1) An improvement in either pain or function of at least 50 percent accompanied by an absolute decrease of at least 20 mm on the visual-analogue scale for pain or function, OR 2) The occurrence of at least two of the following: a) a decrease in pain of at least 20 percent accompanied by a decrease of at least 10 mm on the visual-analogue scale; b) an improvement in function of at least 20 percent and a decrease of at least 10 mm on the visual-analogue scale; c) an increase in the patient's global assessment score by at least 20 percent accompanied by a decrease of at least 10 mm on the visual-analogue scale

Participant Flow

Participants were recruited at 2 medical centers between May 2015 and January 2019. The first participant was enrolled May 2017 and the last participant was enrolled in January 2019.

140 participants began, and 136 completed, the 4-Week Sham Run-in Period. 4 of the 140 Sham Run-in participants were withdrawn due to being less than 80% treatment compliance.

The study has been designed to determine if PLIUS potentially diminishes articular cartilage thinning by measuring cartilage thickness in the tibial femoral joint. The measure selected to best evaluate this is cartilage thickness of the central medial femoral condyle because studies of the OAI (Osteoarthritis Initiative) data have shown this region to be among those most sensitive to change and, due to the anatomical positioning of the device, the most likely to be affected by treatment.

The WOMAC® Index questionnaire is a tri-dimensional, disease-specific, self-administered, health status measure. It probes clinically important, patient-relevant symptoms in the areas of pain, stiffness and physical function in patients with osteoarthritis of the hip and/or knee. The WOMAC has been linguistically validated and is a reliable and responsive measure of outcome, and has been used in diverse clinical and interventional environments. Range is from 0 - 200. The higher the score, the worse the symptoms.

Population: Intent to Treat

A patient global assessment of disease status on a Visual Analog Scale (VAS) will be measured at each clinic visit. Patients will be asked to quantify their disease status on a 100 mm VAS as follows: "Considering all the ways your arthritis of the knee affects you, mark 'X' on the scale for how well you are doing." The scale shows the left hand marker "Very Well", and the right hand marker "Very Poor." Range 0 to 100 mm. The higher the score, the worse the symptoms.

This 11-item tool is designed to assess pain in individuals with knee osteoarthritis taking into account both constant and intermittent pain experiences. This tool is designed to be interviewer-administered. Study participants are asked to respond to the questionnaire items based on index knee in the past week (i.e., past 7-day period). Study participants responded to all questions for the same joint. This tool is intended to be responsive to change in OA pain over time or with treatment. Range 0 to 100 mm. The higher the score, the worse the symptoms.
