STATEMENT OF THE PROBLEM:
An experimental study to assess the effectiveness of autologous adipose tissue derived stromal vascular fraction in treatment of knee osteoarthritis and chondral lesions. To observe the Safety and Efficacy of Autologous Stromal Vascular Fraction on Pain and Inflammation associated with Osteoarthritis of the Knee Joint.
OPERATIONAL DEFINITIONS: SVF:
Stromal vascular fraction derived from autologous adipose tissue extracted from mini-liposuction under tumescent anaesthesia. In the vast majority of scientific publications only the term adipose tissue is used, but the true source of SVF cells is not the adipose part but only the stromal (i.e. loose connective tissue) part of the fat obtained typically by liposuction.
SVF contains a large cellular mix inclusive of;
DEFINITION OF KOOS Score:
(Knee Injury & Osteoarthitis Outcome score) scoring system was used to assess the outcome. The KOOS is a knee-specific instrument, developed to assess the patients’ opinion about their knee and associated problems. The KOOS evaluates both short-term and long-term consequences of knee injury. It holds 42 items in 5 separately scored subscales; Pain, other Symptoms, Function in daily living (ADL), Function in Sport and Rec- reation (Sport/Rec), and knee-related Quality of Life (QOL).(21)
INTRODUCTION TO THE PATIENT DEMOGRAPHIC
We have given SVF injection to 31 patients from May 2015 to July 2015, in 62 joints. Most of the patients were in age group 41-60 yrs. i.e. 19 out of 31 (Range 26yrs to 78 yrs.). As per sex distribution there was 23 female and 8 male in study. We studied 19 patients 38 joints were injected with SVF with minimal follow-up of 6wks in detail and we are able to demonstrate safety with no serious side effects reported in 6 week of follow-up and clinical improvement in a vast majority of patients. Some patient’s experienced local pain and swelling at the injection site, but those symptoms were lasting shortly and were well controlled with common analgesics.
BMI ranges from 21.5 to 37 in 19 patients. 5 patients (26.3 %) had associated cardiovascular disease, 1 patient (5.3%) had migraine and one patient (5.3%) had undergone unicompartment knee arthroplasty but majority 12 patients (63.2%) patients had no associated disease. One Patient had grade II, 12 patients had grade III & 6 patients had grade IV osteoarthritis (as per Kellgren-Lawrence classification).
MATERIAL & METHODS: A prospective experimental research design is adopted in this study 31 patients were included in the study that had osteoarthritis. All the patients underwent SVF therapy. Out of which 19 patients were followed for their improvement in KOOS scores after 1, 4 and 6 weeks of surgery. Some patients suffered OA in joints other than the knees, the KOOS questionnaire is designed to follow up only the knee joints therefore this is a contributing factor to the loss of follow up. Further study will be done with more number of patients with longer follow-up.
Lipo aspiration (Performed by surgeon on staff):
Cell Seperation Prior to Injection
Injection Method – Intra-Articular
Patient Follow Up:
Hypothesis 1(H1): There is a significant improvement on the pre and post op KOOS score in patients who underwent Autologous adipose derived stromal vascular fraction injection in the treatment of osteoarthritis.
Hypothesis 2 (H2): There is significant correlation between BMI of the patients and their post-operative KOOS score after Autologous adipose derived stromal vascular fraction injection in the treatment of osteoarthritis.
A significance value of P ≤0.05 is used throughout the study to confirm the hypothesis.
DATA ANALYSIS AND INTERPRETATION:
Parametric test is used to find the difference in KOOS scores of 19 patients for various subscale, prior to the surgery, one week after the surgery and 6 weeks after the surgery.
Paired t test was used to find out the difference in pre and post score of patients who underwent SVF therapy.
The intervals were;
A statistical significance is assessed for difference in the scores were found between the scores of Pain, Symptoms, Activity of Living (AoL), Quality of Life (QoL), average score, before surgery and after one and 6 weeks of surgery. Karl Pearson correlation is used to test the correlation between BMI, grade of Osteoarthritis and different scores of patients after 6 weeks of surgery.
SPSS version 20 was used to do the statistical analysis of the study.
The above table signifies that t test shows extremely significant improvement in KOOS score for Pain (t=-10.926), symptom (t=-5.418), AoL (t=-11.195), QoL (t=-6.633) and average (t=-11.323) when pre-operative & 1 week scores were compared at the level of p ≤ 0.05 (df=18). There is also extremely significant improvement in KOOS scores for Pain (t=-9.545), symptom (t=-4.313), AoL (t=-14.457), QoL (t=-6.274) and average (t=-11.799). When pre-operative & 6 week scores were compared at the level of p ≤ 0.05 (df=18). When scores of 1 week post-op are compared with 6 week post-op there was no significance difference was found in average KOOS, KOOS pain, KOOS symptom & KOOS QoL but there was significant improvement in KOOS AOL (t=), P <0.05.
A positive correlation was found in BMI and average KOOS (r=0.411), KOOS Pain (r=0.492), KOOS symptom (r=0.133), KOOS AoL (r=0.319) and KOOS Qol (0.164) in patients who underwent SVF therapy. A negative correlation was seen between grade of OA and KOOS score improvement in patients who underwent SVF therapy.
A total of 31 patients were treated with a combining 61 joints inclusive of the knee and hip joints.
Several patients suffered comorbidities other than osteoarthritis such as cardiovascular disease, migraine and rheumatoid arthritis prior to having the treatment. These co-morbidities were not followed up to assess the response of the disease when the patient was injected with the SVF.
The minimum follow up period was 6 weeks.
All of the patients whom had been treated (100%) responded to the SVF and showed improvements.
The grades of arthritis which responded were between grades 2, 3 & 4. There were slower improvements noted in patients KOOS scores if the patient had a higher grade of arthritis such as grade 4. These patients still improved.
No serious side effects were noted from the treatment. There were also no systemic infections or reports of cancer upon any of the patient follow ups. This is also confirmed in the literature.
The hypothesis tests confirm 2 items as listed below.
This studies result relied solely on the treatment of SVF and no other contributing factors such as analgesics, physical therapy or other medical inputs to aid in pain relief for the patients osteoarthritis.
