Our treatments

Understanding each option

PRP, Platelet-Rich Plasma
PRP, Platelet-Rich Plasma

Mobilize your own growth factors

PRP is prepared from a small sample of your own blood, spun in a centrifuge to concentrate the platelets and growth factors.

Re-injected under ultrasound guidance at the site of the injury, it stimulates regeneration of tendons and cartilage. Depending on the condition, a 2nd injection may be recommended.

Viscosupplementation
Viscosupplementation

Lubricate the osteoarthritic joint

Viscosupplementation involves injecting hyaluronic acid into an osteoarthritic joint to improve lubrication, cushion impacts and reduce pain.

It is especially indicated for osteoarthritis of the knee, hip, shoulder, ankle or fingers when conventional treatments no longer suffice.

Hyaluronic acid can also be used around certain tendons and ligaments to improve soft-tissue gliding and ease some tendinopathies.

Prolotherapy
Prolotherapy

Stimulate tissue repair

Prolotherapy involves injecting a solution, often dextrose-based, near ligaments, tendons or joints to stimulate the body's natural tissue-repair process.

It aims to strengthen weakened structures and reduce chronic pain, particularly when instability or ligamentous laxity contributes to symptoms.

Cortisone injection
Cortisone injection

Reduce inflammation

Cortisone injections are medical procedures commonly used to treat a wide range of inflammatory conditions affecting joints, tendons and bursae.

By injecting a potent anti-inflammatory directly at the site of pain, under ultrasound guidance, the injection reduces inflammation and relieves discomfort, often for several weeks to several months.

Ultrasound-guided knee injection
N-STRIDE® APS

A biologic treatment for knee osteoarthritis

N-STRIDE APS is an autologous treatment prepared from your own blood, concentrating anti-inflammatory proteins to reduce the pain and inflammation of osteoarthritis.

Mainly indicated for knee osteoarthritis, it is performed under ultrasound guidance and contains no cortisone. A single injection can last up to 2 to 3 years.

Ultrasound-guided knee injection
Hydrogel / Arthrosamid®

Lasting relief, in a single injection

Arthrosamid® is an intra-articular injection used to treat knee osteoarthritis pain. It is a permanent hydrogel (97.5% water) that gradually integrates into the synovial membrane to improve pain and function.

Unlike cortisone, it is not an anti-inflammatory; unlike viscosupplementation, it is not quickly reabsorbed. A single injection is usually enough, and the effects can last several years in some patients.

Patients must take a single dose of antibiotics 1 to 2 hours before the procedure and avoid strenuous physical activity for about 48 hours after the injection.

Calcium lavage

Removing calcium from the tendon

Calcium lavage is a procedure mainly used to treat certain cases of calcific tendinopathy of the shoulder. Under ultrasound guidance, a needle is used to break up and aspirate the calcium deposits in the tendon to reduce pain and improve mobility.

It is generally considered when the calcium deposit is fairly large (usually at least 1 × 1 cm) and symptomatic. A recent imaging exam (X-ray and/or ultrasound) is required before the procedure to confirm the presence and size of the deposit.
