Brief Summary:
Knee osteoarthritis (OA) is characterized by loss of cartilage leading to instability, reduced range of motion, and functional limitations. Current treatment has various limitations so that alternative options to restore function and alleviate joint pain, with the ultimate goal of healing damaged articular cartilage are needed. Mesenchymal stem cells (MSCs) therapy has shown promising results. However, MSCs are limited by complex regulatory issues. Lipogems is a technique to harvest, process, and inject minimally manipulated adipose tissue through mild mechanical force. This procedure is enzyme free and requires no clonal expansion or manipulation. The goal of this study is to evaluate the possible benefits of reduced joint pain and increased joint functionality in patients with knee osteoarthritis after the injection of Lipogems.

Primary Outcome Measures :
  1. Change in Visual Analog Pain Scale (VAS) Over Time [ Time Frame: Pre-op, then post-op: 1 month, 3 months, 6 months, 1 year, 2 years ]
    Scaled pain score to assess change in a patient's knee pain over time. Pain level is marked on a 100 mm line with the 0 mm corresponding to "no pain" and the 100 mm corresponding to 10/10 pain. Using a ruler, the score is determined by measuring the distance (mm) on the 100 mm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-100. The following cut points on the pain VAS have been recommended: no pain (0-4 mm), mild pain(5-44 mm), moderate pain (45-74 mm), and severe pain (75-100 mm).

Secondary Outcome Measures :
  1. Change in the knee injury and osteoarthritis score (KOOS) Over Time [ Time Frame: Pre-op, then post-op: 1 month, 3 months, 6 months, 1 year, 2 years ]
    Patient self-reported outcome measure to assess the patient's opinion about their knee and associated issues. KOOS consists of 5 subscales; Pain, other Symptoms, Function in daily living (ADL), Function in sport and recreation (Sport/Rec) and knee related Quality of life (QOL). Standardized answer options are given (5 Likert boxes) and each question gets a score from 0 to 4. A normalized score (100 indicating no symptoms and 0 indicating extreme symptoms) is calculated by adding the subscales together.
