Knee osteoarthritis (OA) is a common and often debilitating condition, particularly for patients who have had a meniscectomy and continue to experience lingering symptoms. The meniscus is essential for cushioning the knee and absorbing shock; when it is removed, patients may face ongoing aches and difficulties with everyday activities. Arthrosamid is a novel injectable treatment designed to address these specific issues. This article looks at how Arthrosamid might help manage persistent post-meniscectomy symptoms within the wider context of osteoarthritis care.
When the meniscus is removed, the knee’s natural biomechanics are altered significantly. The meniscus normally distributes pressure across the joint and absorbs shock during movement, so without it, the cartilage and other parts of the knee take on extra strain. This often leads to reduced joint function, aches that won’t go away, and difficulties returning to normal walking. As some experts highlight, “Meniscus deficiency was recognised to lead to an early onset knee osteoarthritis (OA)” (Drobnič et al., 2019). Unfortunately, traditional treatments don’t always tackle these mechanical problems, and “Evidence for non‐surgical management of post‐meniscectomy knee pain is lacking” (Drobnič et al., 2019), leaving many patients underserved.
Arthrosamid is an injectable hydrogel made primarily from polyacrylamide. It acts as a cushion inside the joint, helping to restore some of the shock absorption lost after meniscectomy. Approved for use across Europe, it offers a non-surgical option to improve joint function and reduce symptoms. Recent research notes that “PAAG provided improvement in knee OA symptoms over 24 months, in older, non-diabetic patients with lower KL grades” (Gao et al., 2025a). While the evidence is still developing, Arthrosamid appears promising for easing symptoms without the need for more invasive procedures. However, it is important to remember that “The absence of a control group and limited outcome measures should be considered. Further studies are warranted to validate efficacy, refine patient selection, and evaluate long-term impact” (Gao et al., 2025a).
Professor Paul Lee, a respected orthopaedic surgeon and cartilage specialist, leads the London Cartilage Clinic with a focus on personalised care. As both a Cartilage Expert and ambassador for the Royal College of Surgeons of Edinburgh, he oversees a professional and supportive environment where patients with knee OA receive thorough assessments. Here, Arthrosamid and other innovative treatments are considered carefully, ensuring patients get expert advice tailored to their unique needs.
Not every patient is suitable for Arthrosamid, so proper evaluation is key. Recent studies show that “patient factors that increased the odds of reaching minimal clinically important difference in symptoms by 24 months include being older, having a lower knee OA grade, not having diabetes, and having bilateral rather than unilateral knee OA” (Gao et al., 2025a). The treatment is generally safe and well tolerated, but it is important to consider each patient’s individual condition and health. Experts also remind us that “Post‐meniscectomy pain syndrome and post‐meniscectomy knee OA are common findings after meniscus resection” (Drobnič et al., 2019), so a carefully tailored, patient-centred approach remains essential.
For osteoarthritis patients who have previously had meniscal surgery, Arthrosamid offers a promising option to tackle persistent symptoms by helping restore shock absorption lost through meniscal removal. It should be viewed as part of a personalised treatment plan, developed alongside specialist advice and thorough patient assessment. For any medical concerns or tailored advice, always consult a qualified healthcare professional.
