Study type
Description of intervention(s) / exposure
This study will look to assess the safety and response of focal chondral lesions of the knee to injection protocols of stromal vascular fraction (SVF) and platelet rich plasma (PRP) in comparison to accepted conservative mangement. Thirty two participants will be enrolled in the study and randomly separated into 2 study groups.

Group 1: [SVF (IA) + PRP (IA)] at Day 0 + PRP (IA) at Days 7, 14 & 28
Group 2: accepted conservative management including: simple analgesics, weight loss education, regular exercises, biomechanical adjustment

Autologous non-expanded SVF from adipose (fat) will be used due to the ease of harvest (liposuction) and safety. On average 100 million cells are injected into the joint. Adipose tissue is removed by lipo-aspiration (about 60 minutes). The fat is processed on-site to isolate the cells (this process takes up to 40 mins). The suspension of stromal stem cells is injected into the knee joint under ultrasound guidance. The PRP (3ml) process involves separating out platelets with plasma from a small amount of blood taken, and takes about 15 mins.

The harvesting of adipose and the PRP processing will be performed on the same day as the injection of SVF and PRP, respectively.

Comparator treatment: accepted conservative management including: simple analgesics, weight loss education, regular exercises, biomechanical adjustment. Conservative management will be by face to face meeting with the doctor on Days 0, 180 and 365.
Control group

Primary outcome [1] 299441 0
Safety and tolerability of autologous stromal vascular fraction (SVF) and platelet rich plasma (PRP) for the treatment of focal chondral lesions of the knee. Adverse Events will be graded by the Common Terminology Criteria for Adverse Events v 4.0 (CTCAE) and coded according to MedDRA terminology. Loco regional Adverse Events will be monitored (e.g. knee swelling, infection). Systemic Adverse Events will monitored by. laboratory parameters including [blood tests: Complete Blood Count (CBC), Comprehensive Metabolic Panel (CMP), and pregnancy test for female patients], and vital signs (temperature, heart rate, blood pressure, respiration rate and weight),

Statistical methods / analysis
The study safety results will be analysed by descriptive statistics, as rigorous inferential statistics will not be feasible due to the small treatment group sample size. The primary analysis for safety will report all subject adverse events.

All efficacy analyses will be performed using the Intention to Treat (ITT) population. The chosen sample size of 32 patients allows for 16 patients per treatment cohort which is sufficient to detect a difference between the comparison group and SVF (with PRP) group in the mean percentage change over time in KOOS scores of 20% with a standard deviation of 10% or difference of 10% with a much larger standard deviation of 20%.

The endpoints for the MRI will be to assess disease modification following cartilage mapping of the MRI scans. The reviewer will indicate whether a participant has improved cartilage volume and the degree or not, or that degeneration has slowed in comparison to the placebo control. No formal statistical tests will be undertaken.
