Arthromac is an intra-articular viscosupplement containing sodium hyaluronate. It is injected into the knee joint by a trained medical practitioner and may help selected patients manage symptoms of knee osteoarthritis. It is not a steroid or stem-cell therapy.

01 / How it works
Healthy synovial fluid helps reduce friction and absorb mechanical load inside the knee. With osteoarthritis, the joint environment changes and the quality of natural joint fluid may become less effective. Arthromac contains highly purified, high-molecular-weight sodium hyaluronate of non-animal origin. This hyaluronic acid is injected directly into the joint to supplement the viscoelastic properties of the joint fluid.
This process, called viscosupplementation, may help selected patients manage osteoarthritis-related knee pain and stiffness, potentially improving mobility and comfort during daily activities. However, it is crucial to understand that Arthromac is not a steroid, PRP, or a stem-cell injection. It cannot replace missing cartilage, correct severe deformity, or repair a torn ligament. Because clinical guidelines differ on routine HA injections, our doctors carefully evaluate each case to ensure any proposed intervention is medically appropriate and aligns with your functional goals.

Who may benefit
Knee pain does not automatically mean you need a hyaluronic acid injection. The cause of the pain must be established first.
Clinical Diagnosis: Symptoms may arise from meniscal injuries, ligament issues, referred spine pain, or inflammatory conditions like gout. We review your available imaging, medical history, medications, and previous injections to confirm if knee osteoarthritis is the actual cause.

If an Arthromac knee injection is deemed suitable after shared decision-making, the procedure focuses heavily on strict infection-control practices. The knee is prepared using a strict aseptic technique before the single intra-articular injection is performed by our trained doctor.
Follow-up & Travel: Because evidence for intra-articular HA is mixed, we prioritize careful patient selection. Singapore patients travelling to Johor Bahru via the Causeway or Tuas Second Link should bring previous imaging and medication lists. While patients can usually return home after an uncomplicated outpatient injection, strenuous exercise should not be planned immediately afterwards, and same-day treatment depends entirely on clinical suitability during the consultation.
While some patients experience gradual symptom improvement, others may receive little or no benefit. Short-term effects after an intra-articular injection may include discomfort at the injection site, mild swelling, stiffness, bruising, or a temporary feeling of joint fullness. We will advise you to protect the knee from unnecessary strain and avoid strenuous lower-body exercise, running, jumping, or heavy lifting for approximately 24–48 hours following the procedure.
It is critical to monitor for any acute inflammatory reaction or signs of a serious joint infection (septic arthritis). If you experience rapidly increasing severe pain, marked swelling, spreading redness, fever, or an inability to bear weight, prompt medical assessment is required. Joint injection is only one part of broader osteoarthritis care, which should still involve physiotherapy, exercise, and supportive weight management where relevant.

Arthromac is an intra-articular viscosupplement containing sodium hyaluronate. It is injected into the knee joint by a trained medical practitioner and may help selected patients manage symptoms of knee osteoarthritis. It is not a steroid or stem-cell therapy.
Yes, Arthromac is listed in Malaysia’s Medical Device Authority register as a sodium hyaluronate solution for osteoarthritis use. It should be described as a registered medical device rather than an approved medicine.
Arthromac is designed as a single-injection viscosupplementation product. However, the doctor must first confirm the diagnosis and treatment suitability. A single-injection format does not guarantee a better result for every patient.
The injected sodium hyaluronate is intended to supplement the viscoelastic properties of the knee’s synovial fluid. This may improve lubrication and cushioning, reducing pain or stiffness. It does not replace lost cartilage.
Improvement is not always immediate. Some patients may notice gradual changes over the following weeks, while others may experience limited or no meaningful benefit. The onset and degree of improvement vary.
