Lipogems Prospective Study

Phase 4

Terminated

Conditions: Knee Osteoarthritis

Interventions: Procedure: Debridement only
Device: Lipogems Device PLUS debridement

Registration Number: NCT03922490

Lead Sponsor: Hospital for Special Surgery, New York

Brief Summary: The purpose of this study is to study the clinical outcomes and effects of the injection of fat-derived stem cells (the scientific name being "adipose derived autologous stem cell transplantation (ADAT)") as an addition to knee arthroscopy in the treatment of knee swelling and pain associated with mild to moderate knee osteoarthritis. Management of this condition remains a pervasive problem within orthopaedics. Lipogems is a Food and Drug Administration (FDA) approved technique. Lipogems is the name of the technology used to obtain stem cells from fat that will be aspirated/removed by suction from the abdomen. Fat will be processed to obtain stem cells which will then be injected into the knee after the physician completes knee arthroscopy. The study that we are asking patients to enroll in is important because it will attempt to answer the question about whether fat-derived stem cells added to knee arthroscopy is better, worse or no different than knee arthroscopy alone. Currently, without this study, we do not have an answer to this question.

Detailed Description: Protocol Outline:

* The patient will undergo a diagnostic knee arthroscopy. This procedure would have been performed regardless of enrollment in the study. During the diagnostic knee arthroscopy, the surgeon will determine whether the patient is eligible to participate in the study.

* If the patient has a torn meniscus, inflamed joint lining or loose fragments in the knee, this will be removed and treated and he/she will still be eligible for the study.

* If, however, the physician determines that the patient needs more invasive treatments (such as cartilage transplantation, meniscal repair, removal of a substantial amount of your meniscus), then he/she will be excluded from the study and will not have fat tissue suctioned from his/her abdomen. The standard of care treatment will then proceed based on the physician's judgement.

* After the surgeon completes the arthroscopic procedure, the recommended amount of fat-derived stem cells (about 2 teaspoons) will be injected into the knee. There will be approximately 1 teaspoon of excess fat derived stem cells, which will be transported to our research facility so that the contents can be stored for later examination.

* After surgery, 5 visits are required by the patient over the following 12 months: at 2 weeks after surgery to monitor his/her incision, at 6 weeks, 12 weeks, 6 months and then finally 12 months.

The results are used to calculate two summary scores: a Global Physical Health Score and a Global Mental Health score. These scores are then standardized to the general population, using the "T-Score". The average "T-Score" for the United States population is 50 points, with a standard deviation of 10 points. Higher scores indicate a healthier patient. 11-point scale question recalculated to a 5 point scale. only 8 of 10 questions used for scoring calculations (Each sub-score is generated by 4/8 questions) - 4Qs, 5 points each Scale from 0-20 to calculate Global Mental Health Raw Score (higher score means better outcome) Scale from 0-20 to calculate Global Physical Health Raw Score (higher score means better outcome) The raw scores are then standardized to general population using the "T-score": Global physical health t-score range: 16.2-67.7 Global mental health t-score range: 21.2-67.6
