When pain from a joint injury, tendinopathy, or ligament damage persists long after the initial healing phase, it often means the underlying connective tissue never fully repaired. Prolotherapy is a regenerative injection therapy designed to address that problem directly by stimulating your body’s own repair process in tissue that has become chronically painful or unstable.
The treatment uses a dextrose solution, a concentrated sugar-based compound, injected into the specific tendons, ligaments, or joint structures contributing to your pain. The injection creates a controlled, localized response that recruits healing cells to the area and promotes the formation of new collagen, strengthening and repairing damaged tissue over time.
A systematic review and meta-analysis published in Anesthesia and Pain Medicine found that dextrose prolotherapy produced significant reductions in pain scores compared to saline injection in patients with chronic musculoskeletal pain, with benefits sustained from six months to one year after treatment (Bae et al., 2021). For patients who have not found lasting relief through physical therapy, anti-inflammatory medications, or corticosteroid injections, prolotherapy offers a pathway focused on repair rather than symptom management.
Chronic pain in tendons, ligaments, and joints often persists because injured connective tissue heals incompletely. Tendons and ligaments have limited blood supply, which slows the natural repair process. When healing stalls, the tissue may become lax, structurally weak, or chronically inflamed, leading to pain that does not resolve on its own.
Prolotherapy works by restarting the repair cycle in these tissues. A small amount of dextrose solution is injected at precise locations where the affected tendon or ligament attaches to bone. The mildly irritating solution triggers a localized inflammatory response at the injection site. This recruits growth factors and healing cells to the area, stimulates collagen synthesis, and promotes the regeneration of stronger, more functional connective tissue.
Research published in the Clinical Medicine Insights: Arthritis and Musculoskeletal Disorders supports the effectiveness of dextrose prolotherapy across a range of musculoskeletal conditions, with positive outcomes confirmed in randomized controlled trials for tendinopathies, knee osteoarthritis, and sacroiliac pain (Hauser et al., 2016).
Unlike corticosteroid injections, which reduce inflammation temporarily but can weaken tissue with repeated use, prolotherapy is designed to strengthen and rebuild the structures causing your pain. The treatment works with your body’s biology rather than suppressing it.
Prolotherapy is used to treat chronic pain arising from damaged or incompletely healed connective tissue. It is particularly well-suited for conditions involving tendons, ligaments, and joint structures that have not responded to conservative care.
Conditions that may respond to prolotherapy include:
Prolotherapy is often used alongside other regenerative treatments at ReNova Health, including PRP therapy, MLS Laser Therapy, and SoftWave therapy, depending on the nature and severity of your condition. Your provider will evaluate your full clinical picture and recommend the approach most appropriate for your situation.
Before beginning prolotherapy, you will meet with a ReNova Health provider for a comprehensive evaluation. Your provider will review your health and injury history, assess the specific structures involved in your pain, and determine whether prolotherapy is appropriate for your situation. We take time with every patient to understand what has and has not worked before recommending a path forward.
Prolotherapy sessions are completed in the clinic. After reviewing the treatment plan and answering any questions, your provider will clean and prepare the treatment area. The dextrose solution is then injected at the specific tendon or ligament attachment points identified as sources of your pain. Multiple injection sites may be treated in a single session depending on your condition.
Most patients describe the injection as a brief, sharp sensation followed by a feeling of pressure at the injection site. Some soreness in the treated area is normal in the days following a session as the healing response activates. This temporary soreness is a sign the treatment is doing what it is designed to do and typically resolves within a few days.
Prolotherapy is delivered as a series of sessions spaced several weeks apart to allow the repair process to progress between treatments. The number of sessions needed varies by condition, the severity of tissue damage, and how your body responds to initial treatments. Your provider will outline a recommended course during your consultation and monitor your progress throughout.
Improvements from prolotherapy develop gradually as new collagen forms and the repaired tissue strengthens. Many patients notice meaningful improvement within several weeks of beginning treatment, with continued progress over the following months.
ReNova Health’s clinical team brings specialized training in regenerative and orthobiologic medicine to every patient evaluation. Jacob Miller, MSN, CRNA, ARNP, holds a fellowship in chronic pain management and advanced training in orthobiologics and functional medicine. Our providers understand the biology of connective tissue injury and approach prolotherapy as a targeted, evidence-informed intervention, not a generalized pain management tool.
ReNova Health is a member of the Interventional Orthobiologics Foundation (IOF), reflecting our commitment to evidence-informed practice and continuing education in regenerative medicine. Our IOF membership means the standards we apply to prolotherapy and other orthobiologic treatments are consistent with those of leading specialists in the field.
The outcome of prolotherapy depends significantly on the accuracy of injection placement. Our providers use their training in musculoskeletal anatomy and injection technique to target the specific tendon and ligament attachment points contributing to your pain. Precise placement means the healing response is directed exactly where it needs to go.
Prolotherapy is one component of a broader regenerative pain management approach at ReNova Health. When your condition calls for it, your provider may recommend combining prolotherapy with PRP therapy, MLS Laser Therapy, or SoftWave therapy to support more comprehensive healing. Every treatment plan is built around your specific injury, history, and goals.
Chronic pain from injured tendons, ligaments, and joints does not have to be something you simply manage. Prolotherapy addresses the underlying structural problem by giving your body the signal it needs to repair tissue that never fully healed. Our team at ReNova Health will evaluate your condition and help you understand whether prolotherapy is the right fit for your care plan.

Yes. Prolotherapy is frequently used alongside other regenerative therapies at ReNova Health, including PRP therapy, MLS Laser Therapy, and SoftWave therapy. Combining treatments can support more thorough healing for complex or persistent conditions. Your provider will determine the most appropriate approach or combination based on your individual situation.
