Autologous Stromal Vascular Fraction of Cells for Treatment of Knee Articular Cartilage Dystrophy
- Conditions
- Knee Osteoarthritis
- Interventions
- Procedure: LiposuctionOther: SVF isolationOther: Intraarticular administration of autologous SVF
- Registration Number
- NCT02827851
- Lead Sponsor
- Central Clinical Hospital w/Outpatient Health Center of Business Administration for the President of Russian Federation
- Brief Summary
Stromal vascular fraction of cells (SVF) will be extracted from lipoaspirate by enzymatic digestion. SVF will be administered in a single dose intraarticularly 4 weeks after arthroscopic debridement. All patients will receive cell therapy.This is a single arm study with no control.
- Detailed Description
Patients undergone arthroscopic debridement for knee osteoarthritis will be subjected to abdominal liposuction under local anaesthesia. Harvested adipose tissue will be processed according to patent pending technology based on enzymatic digestion, washing and concentration of cell pellet in 5 ml of Hartmann's solution. Isolated SVF will be administered in a single dose into anterior part of knee joint cavity 28 days after arthroscopy.

Group Intervention Description SVF injection Liposuction Subjects will undergo liposuction under local anesthesia. Lipoaspirate will be processed to isolate and concentrate stromal vascular fraction of cells (SVF). After SVF isolation autologous cells suspension will be injected intraarticularly into knee joint. SVF injection SVF isolation Subjects will undergo liposuction under local anesthesia. Lipoaspirate will be processed to isolate and concentrate stromal vascular fraction of cells (SVF). After SVF isolation autologous cells suspension will be injected intraarticularly into knee joint. SVF injection Intraarticular administration of autologous SVF Subjects will undergo liposuction under local anesthesia. Lipoaspirate will be processed to isolate and concentrate stromal vascular fraction of cells (SVF). After SVF isolation autologous cells suspension will be injected intraarticularly into knee joint.
