This study will be a randomised control trial of the use of intra-articular Arthrosamid® a novel intraarticular hydrogel vs. standard of care (steroid and local anaesthetic) for the non-operative management of knee osteoarthritis.
The authors aim is to study the effect of this intra-articular medication by randomising approximately 100 patients to the treatment arm of the study Arthrosamid, and 100 patients to the control arm (which will be the current standard of care currently provided at CNOH: intra-articular steroid and bupivacaine). Patients will be referred from Orthopedic clinics and will be eligible if have symptomatic knee pain and arthritis show on prior imaging. Patients will be given information about the study and given time to choose to be enrolled. They will sign consent forms prior to the study. They will be randomized into 2 groups. Both will get single knee joint injections into 1 knee. Either Arthrosamid or intra-articular steroid and bupivacaine. They will be blinded to what they have gotten. They will be followed up at 3, 6 , 12 and 18 months with MRI imaging and functional assessment to assess which is better.

Arthrosamid is a non-biodegradable, 2.5% polyacrylamide hydrogel (iPAAG) injection designed as a long-lasting, non-surgical treatment for knee osteoarthritis. It acts as a synovial implant that provides cushioning, reduces pain, and improves mobility for up to 3-4 years, often delaying the need for knee replacement surgery.

RECRUITINGWestern Ontario and McMaster Universities Arthritis Index (WOMAC).
Self-administered questionnaire (24 items) assessing pain, stiffness, and physical function in patients with hip or knee osteoarthritis. Pain (5 items): during walking, using stairs, in bed, sitting or lying, and standing upright Stiffness (2 items): after first waking and later in the day Physical Function (17 items): using stairs, rising from sitting, standing, bending, walking, getting in / out of a car, shopping, putting on / taking off socks, rising from bed, lying in bed, getting in / out of bath, sitting, getting on / off toilet, heavy domestic duties, light domestic duties The test questions are scored on a scale of 0-4, which correspond to: None (0), Mild (1), Moderate (2), Severe (3), and Extreme (4).
Time frame: Before the onset of treatment, then 3, 6, 12 months after with possibility of follow up 18 months.
MRI knee
MRI of the affected knee with contrast to test for synovitis.
Time frame: Before the onset of treatment, then 3, 6, 12 months after with possibility of follow up 18 months.
EuroQol-5 Dimension-5 Level health questionnaire.
Questionnaire developed by the EuroQol Group to measure health-related quality of life. The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state. 1= no problem, 5 = maximum problems. Example shown below MOBILITY : 1. I have no problems in walking about 2. I have slight problems in walking about 3. I have moderate problems in walking about 4. I have severe problems in walking about 5. I am unable to walk about
Time frame: Before the onset of treatment, then 3, 6, 12 months after with possibility of follow up 18 months.

Visual numerical pain rating scale (VNS)
The Visual Numerical Scale (VNS) is a self-reported pain assessment tool that combines a 0-10 numeric scale with visual, pictorial, or graphic aids. 0 = no pain. 10 = worst pain possible
Time frame: Before the onset of treatment, then 3, 6, 12 months after with possibility of follow up 18 months.
