Knee osteoarthritis is a common source of pain and limited mobility. For mild to moderate cases, the first line of treatment is always conservative: leg and hip strengthening exercises, physical therapy, activity modification, and weight management. These approaches help improve joint function and slow progression of arthritis.
But what if these measures aren’t enough? Injections are often considered the next step—but not all options are equally effective or safe long-term.
Why Steroid Injections Are Less Ideal
While steroid injections may provide short-term pain relief, they are not recommended for long-term joint health. They can negatively affect surrounding tissues and typically offer only temporary improvement.
Hyaluronic acid injections (sometimes called “gel injections”) have been used as an alternative. These treatments can provide a few months of relief, but their effectiveness is limited, and insurance coverage for them has become inconsistent.
Prolotherapy: A Safe and Effective First Injection Option
A highly underutilized yet effective treatment is prolotherapy, one of the original regenerative medicine approaches. Prolotherapy treats not just the joint itself, but also the surrounding soft tissue structures—ligaments, tendons, meniscus, and other supporting tissues.
The goal is to strengthen the entire functional unit of the joint, improving stability and reducing long-term pain. This holistic approach targets the root causes of degenerative arthritis, rather than just masking symptoms.
How Prolotherapy Works
Prolotherapy typically uses a solution of dextrose (sugar water) as a mild irritant to stimulate the body’s natural healing response. Treatments are usually given monthly for three to six sessions, depending on severity. Over time, this process strengthens the joint and surrounding tissues, gradually improving function and reducing pain.
Benefits of Dextrose Prolotherapy
- Effective for many patients with mild to moderate knee osteoarthritis
- Affordable and accessible compared to some newer regenerative therapies
- Minimal downtime with progressive improvement in joint stability and pain relief
For patients with mild to moderate knee osteoarthritis who continue to experience pain despite lifestyle adjustments, dextrose prolotherapy is a safe, effective, and practical first injection option.
If you are considering injections for knee osteoarthritis, prolotherapy may be the ideal next step before exploring stronger regenerative treatments such as PRP or stem cell therapy.
