Orthopedic injections – also called viscosupplements or hyaluronic acid (HA) knee injections – are used to manage the pain and stiffness of knee osteoarthritis. By supplementing the joint’s synovial fluid, they help restore lubrication and cushioning, and can delay the need for more invasive options. Kinami Health supplies genuine viscosupplements from SYNVISC®, MONOVISC®, ORTHOVISC®, DUROLANE® and CINGAL® to Canadian clinics, orthopaedic surgeons, rheumatologists, sports medicine physicians and licensed professionals, with wholesale pricing and fast delivery.

The orthopedic injection brands available for the Canadian market:
Orthopedic injections are not interchangeable. Clinicians usually compare them on four criteria.
| Brand | HA source | Protocol | Dose per injection |
| SYNVISC-ONE® | Hylan G-F 20 (avian) | Single injection | 6 mL |
| SYNVISC® | Hylan G-F 20 (avian) | 3-injection course | 2 mL |
| MONOVISC® | Non-animal, cross-linked | Single injection | 88 mg / 4 mL |
| ORTHOVISC® | Non-animal, high molecular weight | Multi-injection course | 2 mL |
| DUROLANE® | Non-animal, stabilized (NASHA) | Single injection | 60 mg / 3 mL |
| CINGAL® | Non-animal, cross-linked + corticosteroid | Single injection | 88 mg HA + 18 mg triamcinolone hexacetonide / 4 mL |
In a healthy knee, synovial fluid is rich in hyaluronic acid, which makes it viscous and elastic: it lubricates the joint during slow movement and absorbs shock during impact. In osteoarthritis, the concentration and molecular weight of this hyaluronic acid decrease, the fluid loses its protective properties, and pain, stiffness and reduced mobility follow.
Viscosupplementation restores part of these properties by injecting hyaluronic acid directly into the joint. It is mainly indicated for patients with mild to moderate knee osteoarthritis who have not responded adequately to conservative treatment such as simple analgesics, physiotherapy or weight management. Depending on the product and the patient, relief may last up to six months, and treatment can be repeated according to clinical response.
Orthopedic injections are for intra-articular use only and must be administered by qualified healthcare professionals trained in joint injection techniques, using strict aseptic technique. Joint effusion should be aspirated before injection where present, and image guidance can improve accuracy. In Canada, who may administer intra-articular injections varies by province and professional college, so practitioners should follow the rules that apply in their own jurisdiction. Product-specific technique is detailed on each brand page.
Viscosupplements are generally well tolerated. The most common reactions are temporary pain, swelling, warmth or stiffness in the injected joint, usually resolving within a few days. They should not be used in the presence of joint or skin infection at the injection site, or in patients with known hypersensitivity to any component – including avian proteins for hylan-based products. CINGAL® also carries the precautions associated with corticosteroids. In Canada, adverse reactions can be reported to Health Canada.
