Clinical Trial Summary

The study aims to conduct a randomized trial comparing the clinical outcomes of PRP (standard intervention) versus Microfragmented adipose tissue (investigational) for the treatment of knee osteoarthritis. Hypothesis: Both interventions will result in significant improvement in patient-reported outcomes. We hypothesize that Microfragmented adipose tissue will provide superior outcomes.


Description:

Background Knee osteoarthritis is a leading cause of disability worldwide. Standard of care treatments for knee OA include activity modification, weight loss, therapeutic exercise and injections like corticosteroids and viscosupplement. These commonly used non-operative treatments focus on symptom palliation, but are not disease modifying. Orthobiologics have emerged as a promising treatment for knee OA. The most widely studied orthobiologic is platelet-rich plasma (PRP). PRP is a dense concentration of platelets derived from autologous whole blood and platelets are concentrated 2-5x compared to baseline. The platelets have demonstrated anti-inflammatory and chondroprotective properties.6 PRP has been shown superior to placebo and viscosupplement for knee OA in several clinical trials. While PRP is the most widely studied and used orthobiologic, it contains only platelets. Therefore, a simple, office-based intervention able to collect additional reparative cells to treat knee OA would be ideal. Adipose (fat) is a known source of reparative cells like pericytes and it can be easily and safely aspirated in the clinic. The adipose tissue aspiration and processing is accomplished through a simple process. After local anesthesia to the site of adipose aspiration (lower abdomen or buttock), 30ml of adipose is aspirated through a cannula. That adipose is then processed in accordance with FDA guidelines including minimal manipulation to remove oils.. Using minimally manipulated Microfragmented adipose tissue has been shown safe for use as injection therapy for knee OA for 3 years. Methods: Patients / Outcome Measures / Sample size: Patients with unilateral symptomatic knee OA will be recruited from the sports medicine and orthopedics clinics, as well as advertising flyers within the clinic. All patients' first visit will include a medical evaluation and assess best treatment plan for that patient, regardless of candidacy for this study. This evaluation includes x-rays of their knees as a standard part of the evaluation. If they meet criteria and choose to enroll, they will be randomly assigned to either the PRP or Microfragmented adipose tissuetreatment group. Patients will complete follow up visits and surveys at defined time points through 12 months.

Study Design


Intervention

Device:
Platelet Rich Plasma
Platelet rich plasma: 157cc of whole blood will be collected, processed, and injected into the knee joint under sterile technique using ultrasound-guidance. Microfragmented adipose tissue: Adipose will be aspirated from the subcutaneous tissue of the buttock or abdomen, processed, and injected into the knee joint under sterile technique using ultrasound-guidance.

Outcome

Type Measure Description Time frame Safety issue
Primary KOOS Pain [Knee Injury and Osteoarthritis Outcome Score] The Knee injury and Osteoarthritis Outcome Pain Score [KOOS questionnaire] is a self-reported outcome measure assessing the patient's opinion about the pain in their knee. Standardized answer options are given [5 Likert boxes] and each question is assigned a score from 0 to 4. A normalized score [100 indicating no pain and 0 indicating extreme pain] is calculated. 6 months
Secondary VAS [Visual Analog Pain Scale] Pain Score The visual analog pain scale [VAS] is a validated, subjective measure for acute and chronic pain. Scores are recorded by making a handwritten mark on a 10-cm line that represents a continuum between 0 [no pain] and 10 [worst pain]. Baseline, 1 month, 3 months, 6 months, and 12 months
Secondary Tegner Activity Scale The Tegner activity scale is a one-item score that graded activity based on work and sports activities on a scale of 0 to 10. Zero represents disability because of knee problems and 10 represents national or international level soccer. Baseline, 1 month, 3 months, 6 months, and 12 months
