Intervention/exposure

Interventional
Description of intervention(s) / exposure
This procedure will be performed at the minor operation theatre at Aspire Medical Center – Kingdom of Bahrain. Each participant will have his or her own sterile kit that will be used and disposed after the completion of the procedure. Surgical items and instrument is not to be re-used for another procedure. The kit is sterile and the procedure is performed under aseptic technique.
One intravenous cannula will be inserted for the pre-operative analgesia and antibiotic then connected to a normal saline bag to keep the vein open. Thirty minutes before the procedure, a 1g of intravenous Paracetamol and 1g of Ceftriaxone- prophylactic dose of antibiotic intravenously administered to the participant.
During the procedure, only local anesthesia is needed and it will be injected only in the participant’s abdomen- the lipo harvesting site. The participant will be fully awake and aware of what is happening during the procedure while being connected to a nasal cannula for two to four liters of oxygen and monitored via a pulse oximetry.
The orthopedic consultant (the principal investigator (PI)) will perform the procedure solely with the assistance of one scrub nurse and one circulating nurse. In case of any difficulties in lipoaspiration, such as in a case of a very thin participant, a certified plastic surgeon will perform the lipoaspiration only and the remaining steps of the procedure from tissue handling, processing, and intra-articular knee injection will be completed by the PI.
The participant will be lying supine on the theatre bed. They will be exposed from the xiphisternum up to the line drawn between the two anterior superior iliac spines. The harvest site of the procedure is the abdomen. The procedure will take place at both sides of the abdomen. The area will be scrubbed twice with Betadine- an antiseptic solution, and then dried with sterile gauze. Draping of the area will be done using sterile surgical sheets exposing only the area for liposuction.
Procedure steps:
STEP 1 - Harvesting of the adipose tissue
The lower or the lateral abdomen will be chosen as donor site for adipose tissue harvesting. Before harvesting the fat, the site will be injected with Klein solution (1 vial adrenaline + 50 cc lidocaine 2% in 500 cc saline) using a disposable 17G blunt cannula connected to a luer-lock 60-cc syringe. The fat (50 cc) will be then harvested using a 13G blunt cannula, for a fast and a-traumatic suction, connected to a Vaclock"Registered Trademark" 20-ml syringe.
STEP 2 - Processing of the adipose tissue with Lipogems"Registered Trademark" device
The harvested fat will be immediately processed in the Lipogems"Registered Trademark" processing kit, a disposable device that progressively reduces the size of the adipose tissue clusters while eliminating oily substances and blood residues with pro-inflammatory properties. The entire process, carried out in one surgical step, will be performed in complete immersion in physiological solution minimizing any trauma to the cells. The resulting micro-fragmented fat will be collected in a 60-cc syringe and positioned for decanting the excess saline solution. The resulting product will be then transferred into several 1-cc syringes to be injected in the patient.
STEP 3 - Injection in the joint
Micro-fragmented fat (8-10 cc) will be injected to the supralateral angle of patella of each knee. At the end of the procedure, only first aid bandage will be applied to the injection site.

Outcomes
Primary outcome [1] 302105 0
The Western Ontario and McMaster Universities Arthritis Index (WOMAC): The WOMAC is a widely used, proprietary set of standardized questionnaires used by healthcare professionals to evaluate the condition of patients with OA of the knee and/or hip. This tools measures pain, stiffness, and physical functioning of the joints. This tool is available in Arabic and English languages, and it will be administered by the investigators (ARHP Research Committee, 2015).
Timepoint [1] 302105 0
Changes from baseline of The Western Ontario and McMaster Universities Arthritis Index (WOMAC) at 1, 3, 6 and 12 months.
Primary outcome [2] 302368 0
Knee Injury and Osteoarthritis Outcome Score (KOOS): KOOS is a comprehensive instrument that is used widely for research purposes in clinical trials. It is developed to subjectively assess the patient’s opinion about their knee and associated problems. KOOS is available in Arabic and English languages and it is self-administered by the patient. It can be used over short and long-term time intervals; to assess changes over weeks or over years. KOOS measures pain, function in daily living activities, function in sports and recreation and knee related Quality of Life (QoL) (Roos, 2016).
Timepoint [2] 302368 0
Changes from baseline in Knee Injury and Osteoarthritis Outcome Score (KOOS) at 1, 3, 6 and 12 months.
Primary outcome [3] 302369 0
Visual Analogue Scale (VAS) for pain: the pain VAS is a one-dimensional measure of pain intensity, which has been widely used in diverse adult populations, including those with OA. The VAS is a continuous scale comprised of a 10cm line (100 mm) in length, anchored by 2 verbal descriptors. For pain, the sale is commonly anchored by “no pain” which is “0” on the scale, and “worst pain” which scores “10” on the scale (Hawker, Mian, & Kendzerska, 2011).

Statistical methods / analysis
As an exploratory non-randomized single-arm study, the statistical approaches will be largely descriptive in intent.
Since this study is exploratory, a liberal procedure of testing both primary endpoints at two-sided alpha of 5% will be used, and the proposed sample size of 32-40 patients will provide 80% power to detect a change in mean score with effect size 0.5.
Statistical Analysis
Patient Characteristics
A CONSORT-type diagram will be presented showing:
*Numbers screened, with reasons for ineligibility or refusal, where available
*Numbers completing each stage of the study, with reasons for withdrawal or non-compliance with assessments, where available
Demographic data, vital signs at each visit and efficacy assessments at each visit will be presented in summary tables. Discrete data will be summarized by frequency counts, continuous data by mean, SD, media, quartiles and range.
Primary Efficacy Endpoint
The primary analyses will be done by ANCOVA, testing the null hypothesis that the mean change from baseline is zero, conditional on the baseline value. Data will be assumed to be Normally distributed. The point estimates of mean change and associated 95% CIs will be presented.
Primary Safety Endpoints
* AEs will be tabulated by preferred term and by body system. The maximum-recorded grade per patient of each AE will be displayed in these tables.
* CBC data will be listed, and clinically significant values displayed.
* Any Vital Signs data of clinical significance will be displayed.
Secondary Efficacy Endpoints
The effects of treatment on other scales at 12 months will be assessed as for the primary endpoint. In order to assess the effect of treatment at 12 months, while allowing for the possibility of dropouts, mixed effect models with a random patient effect will be fitted to the changes at 3 and 6 months, using time-point and baseline value as fixed effects. Effects and 95% CIs will be presented. In addition daily average paracetamol usage during the trial will be summarized, and a point estimate and 95% CI presented for the mean value. Finally, changes in MRI will be summarized and thoroughly explained.
Exploratory analyses
To inform future work, residuals from all models will be examined for evidence of skewness or heteroscedasticity. If such is found the impact of appropriate variance-stabilizing transformations will be investigated.
