What Is Prolotherapy?

Prolotherapy — short for proliferative therapy — is a regenerative injection treatment that stimulates the body’s natural healing response in damaged joints, ligaments, and tendons. At ProActive Choice in Bend, Oregon, Dr. Drew Collins MD has used prolotherapy for decades as a cornerstone of natural joint repair for patients who want to heal the underlying structure of their injury, not just mask the pain.

Unlike cortisone, which suppresses inflammation and provides temporary relief without structural healing, prolotherapy works by triggering a controlled healing cascade. A solution — typically containing dextrose (sugar water) and a local anesthetic — is injected into the weakened or injured tissue. This creates a mild inflammatory response that signals the body to send repair cells and growth factors to the area. Over several weeks, collagen is laid down, ligaments tighten, and the structural integrity of the joint improves.

What Conditions Does Prolotherapy Treat?

Prolotherapy is particularly effective for conditions involving joint laxity, ligament instability, and chronic tendon degeneration. At ProActive Choice, Dr. Collins uses prolotherapy for:

• Knee pain and ligament laxity — Including chronic ACL/PCL instability, meniscal support, and knee osteoarthritis. Prolotherapy stabilizes the joint by tightening the surrounding ligamentous structures
• Low back and sacroiliac joint pain — SI joint dysfunction and sacroiliac ligament laxity are among the most common indications for prolotherapy. Many patients who have failed epidurals and chiropractic care find significant relief with prolotherapy to the posterior spinal ligaments
• Shoulder instability and rotator cuff issues — Chronic shoulder laxity and recurring subluxation respond to prolotherapy of the glenohumeral ligaments and rotator cuff attachments
• Hip pain and labral issues — Prolotherapy to the hip capsular ligaments can reduce pain and improve stability in patients with hip laxity or early hip OA
• Ankle instability — Chronic ankle sprains often leave behind stretched lateral ankle ligaments. Prolotherapy tightens these ligaments and restores stability without surgery
• Neck pain and cervical instability — Cervical ligament laxity, often from whiplash or repeated strain, responds to prolotherapy when other conservative treatments have failed
• Tennis elbow and golfer’s elbow — Chronic epicondylitis with tendon degeneration responds well to prolotherapy of the tendon insertion points
• Plantar fasciitis and heel pain — For cases that have not responded to stretching, orthotics, or cortisone, prolotherapy can stimulate healing at the plantar fascia attachment

How Prolotherapy Differs from Other Injections

There are three main injection options for musculoskeletal pain. Understanding the differences helps you make the right choice:

Cortisone injections reduce inflammation immediately but do not heal tissue. Repeated cortisone degrades cartilage and weakens tendons over time. It is a suppressor, not a healer.

PRP (Platelet-Rich Plasma) uses concentrated growth factors from your own blood to actively stimulate tissue repair. It is more regenerative than prolotherapy for acute injuries and cartilage damage but requires a blood draw and centrifugation process.

Prolotherapy uses a simple dextrose solution to trigger the body’s healing cascade — specifically targeted at ligaments and tendons that have lost structural integrity. It is lower cost than PRP, can be repeated more frequently, and is particularly effective for ligament laxity and chronic joint instability. Many patients at ProActive Choice benefit from combining prolotherapy and PRP as a layered regenerative approach.

What to Expect at ProActive Choice

A prolotherapy appointment at ProActive Choice in Bend is straightforward and outpatient. Here is what the process looks like:

1. Initial assessment: Dr. Collins reviews your history, imaging, and physical exam findings to confirm prolotherapy is appropriate and identify all injection targets.
2. Preparation: The skin over the injection site is cleaned and, in some cases, a topical anesthetic is applied.
3. Injection: Dr. Collins injects the dextrose solution at precise anatomical points — ligament attachments, joint capsules, or tendon origins. Depending on the area, multiple injections may be given in a single session.
4. Post-injection: Some soreness and swelling at the injection site is normal and expected over the next 24-72 hours. This is the inflammatory healing response being activated.

Avoid NSAIDs (ibuprofen, naproxen, aspirin) for at least 2 weeks after each prolotherapy session — these anti-inflammatories directly block the healing cascade that prolotherapy is designed to trigger. Ice and acetaminophen can be used for discomfort if needed.

How Many Sessions Are Needed?

Most prolotherapy protocols consist of 3-6 sessions spaced 4-6 weeks apart, though some patients with mild laxity respond in 1-2 sessions and complex chronic cases may benefit from more. The healing timeline reflects real tissue repair — collagen remodeling takes months, not days.

By the end of a full protocol, patients typically notice:

• Reduced joint pain with activity
• Improved stability and reduced “giving way” episodes
• Greater confidence with physical activities — hiking, skiing, cycling, lifting
• Objective improvement in range of motion and strength testing

Prolotherapy Cost in Bend, Oregon

Prolotherapy at ProActive Choice is more affordable than PRP or exosome therapy because it does not require blood processing equipment or biologic materials. Per-session costs vary by the area treated and number of injection sites. Dr. Collins discusses all pricing transparently during your consultation — including options for combining prolotherapy with PRP or other regenerative therapies as a bundled protocol.

Prolotherapy is generally not covered by insurance. However, for patients facing a choice between prolotherapy ($300-$600/session) and surgery (often $15,000-$40,000+ with months of recovery), it is a compelling value proposition for the right candidate.

Is Prolotherapy Right for You?

The best candidates for prolotherapy are patients who:

• Have chronic joint pain with confirmed ligament laxity or tendon degeneration
• Want to address the structural cause of their pain, not just suppress symptoms
• Have tried physical therapy, chiropractic, and cortisone with incomplete results
• Are motivated to complete a multi-session protocol with appropriate recovery
• Want to avoid or significantly delay surgery

Prolotherapy is generally not appropriate for patients with active joint infections, uncontrolled diabetes (elevated blood sugar impairs healing), severe joint degeneration with bone-on-bone arthritis (exosomes or stem cell therapy may be more appropriate), or those taking immunosuppressant medications.

Prolotherapy in Bend, Oregon — FAQ

Where can I get prolotherapy in Bend, Oregon?

ProActive Choice in Bend, Oregon offers physician-supervised prolotherapy under Dr. Drew Collins MD. With nearly four decades of regenerative medicine experience, Dr. Collins provides prolotherapy as part of comprehensive joint care programs serving patients from Bend, Redmond, Sisters, La Pine, and throughout Central Oregon. Call (541) 808-7995 to schedule a consultation.

Is prolotherapy painful?

The injections themselves are briefly uncomfortable — a pressure and stinging sensation at the injection site. Most patients tolerate the procedure well, particularly after the local anesthetic takes effect. Post-injection soreness over 48-72 hours is normal and is actually the desired healing response. Most patients in Bend resume light activities the next day.

How long does prolotherapy take to work?

Most patients notice some improvement within 2-4 weeks of their first session as initial tissue repair begins. Significant structural improvement typically develops over 3-6 months of completing a full protocol. Prolotherapy works with biology — collagen formation and ligament strengthening take time, but the results are structural, not symptomatic.

Can prolotherapy be combined with PRP or exosome therapy?

Yes — and often this combination produces better outcomes than either therapy alone. At ProActive Choice in Bend, Dr. Collins frequently combines prolotherapy (for ligament stabilization) with PRP (for cartilage and acute tissue repair) or exosome therapy (for advanced regenerative support). These complementary modalities target different mechanisms and work synergistically in complex joint conditions.

Does prolotherapy work for back pain?

Yes, prolotherapy has strong evidence for chronic low back pain associated with sacroiliac joint dysfunction, posterior spinal ligament laxity, and facet joint instability. It is one of the better-studied regenerative approaches for back pain that has not responded to epidurals, chiropractic, or physical therapy. Dr. Collins evaluates each case individually to confirm the structural cause before recommending prolotherapy for back pain.
