Detailed Description
Based on the calculation of the sample size using power analysis of the test, investigators plan to include 100 adults with primary knee osteoarthritis in this study. The patients will undergo lipoaspiration under sterile conditions of the operating theatre, the collected lipoaspirates will be further processed - enzymatically with the use of collagenase or mechanically using the Lipogems system. After collection, lipoaspirates will be immediately transferred to the laboratory of the Department of Regenerative Medicine with a tissue and cells bank in Warsaw, and the preparations will be administered to the patients' knee joints in the operating room under ultrasound control.
The Lipogems system is defined as a minimal tissue manipulation system. In contrast, the administration of preparations produced using an enzymatic method requires advanced actions.
Lipoaspiration will be performed using blind cannulas and vacuum syringes introduced through the abdominal wall with a three-millimetre incision on the skin after previous injection to the adipose tissue with modified Klein's solution (500 ml of saline solution, 1 ml of adrenaline, 40 ml of 2% lignocaine), which makes the collection easier. 10 ml of the collected adipose tissue will be used to examine the samples after previous gradient drainage from Klein's solution. Immediately after collection, the samples will be sent to the laboratory for analysis (cell count testing, culture, phenotype identification, analysis by flow cytometry).
The patients will be monitored in the hospital outpatient clinic for one year after the procedure; the control visits will take place: after 2 and 6 weeks, then after 3 and 6 months and after a year. A physical examination and the assessment using the KOOS questionnaire will be performed. Before the procedure and after one year, an X-ray and MRI with T-2 Mapping will be carried out in order to evaluate the condition of the cartilage.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Changes in patients reported outcome measures - Knee Injury and Osteoarthritis Outcome Score (KOOS)
Time Frame: 1,3,6 and 12 months after procedure
|
The KOOS is self-administered and assesses five outcomes: pain, symptoms, activities of daily living, sport and recreation function, and knee-related quality of life.The KOOS's five patient-relevant dimensions are scored separately: Pain (nine items); Symptoms (seven items); ADL Function (17 items); Sport and Recreation Function (five items); Quality of Life (four items). A Likert scale is used and all items have five possible answer options scored from 0 (No problems) to 4 (Extreme problems) and each of the five scores is calculated as the sum of the items included. Scores are transformed to a 0-100 scale, with zero representing extreme knee problems and 100 representing no knee problems as common in orthopaedic scales and generic measures. Scores between 0 and 100 represent the percentage of total possible score achieved. |
