If osteoarthritis affects more than one joint, it is natural to wonder whether several Arthrosamid injections could provide broader relief. Arthrosamid can be used to treat knee osteoarthritis, including in patients with problems affecting both knees, but it is not currently intended as a treatment for every arthritic joint.

Can Arthrosamid Be Used in More Than One Knee?

Yes, patients with osteoarthritis affecting both knees may be considered for treatment in each knee.

The manufacturer has documented patients receiving Arthrosamid treatment in both knees, including people who underwent bilateral treatment during the same period. However, these individual experiences should not be taken as evidence that treating both knees is automatically suitable for every patient.

Each knee should be assessed individually. One knee may have more advanced osteoarthritis than the other, or the pain in each leg may have a different underlying cause.

If arthrosamid injections are being considered for both knees, your clinician should review your symptoms, examination findings, imaging and treatment history before deciding whether treatment is appropriate for each joint.

The timing can also be discussed during your consultation. Your clinician can advise whether treating both knees together or planning treatment separately makes more sense for your mobility and recovery.

Can Arthrosamid Be Used in the Hip, Shoulder or Ankle?

This is where an important distinction needs to be made.

Arthrosamid's stated intended purpose is the symptomatic treatment of knee osteoarthritis in adults. The manufacturer specifies that the hydrogel is intended to be injected into the knee joint and that its clinical evidence relates to knee osteoarthritis.

That means Arthrosamid should not automatically be assumed to be appropriate for osteoarthritis affecting the hip, shoulder, ankle or other joints.

Other types of intra-articular injections have been investigated for osteoarthritis outside the knee, but that evidence cannot simply be transferred to Arthrosamid. Different injectable products have different formulations, indications and supporting research.

If you have pain in several different joints, the appropriate treatment for your knee may therefore be different from the treatment recommended for your hip or shoulder.

What If Osteoarthritis Affects Several Joints?

Pain in multiple joints calls for a broader assessment rather than simply repeating the same injection in every painful area.

Your clinician may first need to confirm whether osteoarthritis is responsible for each symptom. Hip pain, for example, may arise from the hip joint itself, surrounding tendons or referred pain from another area. Similar issues can occur around the shoulder, ankle and other joints.

Treatment can then be tailored to each problem.

For knee osteoarthritis, arthrosamid injections may be discussed alongside exercise, physiotherapy, medicines and other injection options. If another joint is affected, your clinician may recommend a completely different approach depending on the diagnosis and available evidence.

This is particularly important if several joints have become painful at roughly the same time. In some situations, widespread joint symptoms may justify further medical assessment to rule out inflammatory or other underlying conditions rather than treating each painful joint independently.

Will Treating Both Knees Improve Overall Mobility?

If osteoarthritis affects both knees, reducing symptoms in both may help some patients move more comfortably. However, improvement cannot be guaranteed, and each knee may respond differently.

Clinical research into Arthrosamid has focused on pain and physical function following treatment for knee osteoarthritis. Longer-term studies have reported sustained symptom improvements in some patients after a single injection, although individual outcomes vary.

Treating both knees also does not necessarily address every cause of limited mobility. Hip problems, back pain, muscle weakness, balance and general health can all influence walking and everyday function.

Your treatment goals should therefore be discussed before proceeding. For example, you may want to walk further, manage stairs more comfortably or reduce pain during work and exercise.

Discuss Each Joint Before Choosing Treatment

Multiple arthrosamid injections may be considered when osteoarthritis affects both knees, provided each knee is appropriately assessed. However, Arthrosamid is currently intended specifically for knee osteoarthritis and should not be assumed to treat osteoarthritis in other joints such as the hip, shoulder or ankle.

If pain in one or both knees is limiting your mobility, contact Regenesis for a specialist assessment to discuss whether Arthrosamid is suitable and whether each affected joint requires a different treatment approach.
