What is viscosupplementation and what is it used for?

Discover how viscosupplementation works, when it is used, and what benefits it offers for joint health through innovative solutions.

Degenerative joint diseases such as osteoarthritis can compromise the quality of life, causing pain, stiffness, and limited range of motion. For this reason, increasingly targeted and minimally invasive approaches have been developed in recent years to support joint well-being and preserve their functionality over time.

Today, the most effective strategies include treatments aimed at improving the articular microenvironment through formulations designed to promote better lubrication and support the biomechanics of the joint.

In this article, we will discuss what viscosupplementation is, its main clinical indications, and the benefits it can offer.

We will also delve into the differences between viscosupplementation and viscoinduction, and we will see how Phitogen can support medical device and pharmaceutical companies as an outstanding technical and manufacturing partner.

What viscosupplementation is and how it works

Viscosupplementation involves the intra-articular injection of hyaluronic acid-based formulations with the aim of improving joint lubrication. This treatment acts as a true biological “shock absorber”, helping to restore the rheological properties of the synovial fluid.

In a healthy joint, synovial fluid is rich in hyaluronic acid, which nourishes the cartilage and reduces friction. With advancing age or the progression of degenerative diseases such as osteoarthritis, this fluid progressively loses viscosity and elasticity.

This condition reduces the ability to protect the cartilage from mechanical stress, triggering a vicious cycle of pain, inflammation, and functional limitation.

The goal of the injection treatment is precisely to break this cycle by supporting the articular microenvironment, reducing friction between the bone ends, and improving the patient’s functional comfort both at rest and during daily or sports activities.

Clinical indications and benefits of viscosupplementation

The main indications for viscosupplementation concern patients with osteoarthritis or other conditions characterized by alterations in the synovial fluid. The treatment is evaluated by the physician based on the joint’s condition, present symptoms, and therapeutic goals defined for each individual patient during the consultation.

Among the most significant benefits are improved joint lubrication, reduced friction between bone surfaces, and greater comfort during movement. An early approach can help preserve joint functionality for longer and improve the patient’s quality of life.

The joints most frequently subjected to this treatment include:

1. Knee: the most common application, essential for those suffering from knee osteoarthritis (gonarthrosis).
2. Hip: useful for improving mobility and postponing joint replacement surgery.
3. Shoulder, ankle, and small joints of the hand: to alleviate localized pain and improve grip or walking.

The treatment is always evaluated by a medical specialist based on the state of the joint and with the aid of diagnostic tests.

How long do the benefits of viscosupplementation last?

Among the most relevant benefits are the rapid reduction of pain and an increased range of motion.

Depending on the molecular weight of the hyaluronic acid used (low, medium, or high) and the severity of the osteoarthritis, the beneficial effects of a cycle of injections can last from 6 months to over a year. An early approach can also help preserve joint functionality for a longer period.

To achieve long-lasting clinical results, it is essential to use formulations developed according to high-quality standards. Phitogen operates as a technical and manufacturing partner, supporting medical device and pharmaceutical companies in the development of innovative solutions, from research to production, with complete scientific and regulatory support.

Difference between viscosupplementation and viscoinduction

Often confused, these two terms indicate therapeutic approaches with different nuances.

Viscosupplementation primarily aims to restore the viscoelastic properties of the synovial fluid through hyaluronic acid injections. The goal is to improve joint lubrication, reduce friction between surfaces, and promote smoother movement, helping to progressively alleviate pain and stiffness in the affected joints.

Viscoinduction, on the other hand, adopts an approach aimed at supporting the articular microenvironment and the biological processes of the joint. By using hyaluronic acids with specific molecular weights, it aims to stimulate the patient’s synoviocytes, endogenously produce new hyaluronic acid, and modulate local inflammation.

The two strategies should not be considered absolute alternatives, but rather different tools that can be integrated and evaluated by the professional based on the patient’s clinical characteristics. A correct diagnosis allows identifying the most appropriate approach, optimizing the therapeutic pathway and the expected functional goals over time.

Manufacturing viscosupplements with Phitogen

The production of viscosupplements requires scientific expertise, controlled manufacturing processes, and a careful selection of raw materials. Each formulation must be developed to ensure quality, safety, reproducibility, and compliance with the standards required for use in the biomedical sector and modern professional intra-articular applications.

Phitogen operates as a technical and manufacturing partner for medical device and pharmaceutical companies, supporting each project from initial research to formulation, production, and regulatory support. This approach allows the development of customized solutions that meet the specific needs of the international and professional market.

Thanks to years of experience gained in the development of innovative devices, Phitogen also supports private label projects intended for intra-articular applications. The integration of research, quality control, and advanced manufacturing technologies allows the creation of reliable, safe products designed according to high scientific and industrial standards.
