Introduction Long-term results matter — especially with knee injections. So what does the evidence say about Arthrosamid’s effectiveness over time?
1-Year Outcomes Most patients report marked pain relief and improved mobility within the first year. In one European study, 70% showed significant improvement. These improvements were measured using standardised tools like the WOMAC index and patient-reported outcome scores.
3-Year Results A growing number of patients continue to experience benefit after three years, without needing a second injection. Functional improvements in walking, climbing stairs, and reduced dependence on painkillers were noted. The consistent duration of benefit makes it a strong alternative to more invasive procedures.
5-Year Durability Emerging data suggests that Arthrosamid may continue to provide relief beyond five years in select cases. Although long-term studies are ongoing, no significant degradation of the hydrogel has been reported, and patients continue to report sustained pain relief.
Conclusion For patients looking for a non-surgical, long-lasting solution to knee pain, the data on Arthrosamid is very promising. It stands out for its extended duration of action and favourable safety profile over time.
