What Is Prolotherapy?
Prolotherapy, also known as proliferation therapy or dextrose injection therapy, is a minimally invasive regenerative treatment used to manage chronic musculoskeletal pain. It involves injecting a hypertonic dextrose (glucose) solution into injured or weakened ligaments, tendons, or joints to stimulate the body’s natural healing response.
The aim of prolotherapy is to promote tissue repair, improve joint stability, reduce pain, and enhance function. It is most commonly recommended for patients with chronic ligament injuries, tendon disorders, and certain forms of osteoarthritis that have not responded adequately to conservative treatments.
How Does Prolotherapy Work?
The injected dextrose solution creates a mild, controlled inflammatory response at the treatment site. This process is believed to:
- Stimulate the body’s natural healing mechanisms
- Increase collagen production
- Strengthen ligaments and tendons
- Improve joint stability
- Reduce chronic pain
- Restore mobility and function
Healing occurs gradually over several weeks or months, and multiple treatment sessions are often required.
Conditions Treated with Prolotherapy
Prolotherapy may be considered for:
- Knee osteoarthritis
- Shoulder pain
- Rotator cuff tendinopathy
- Tennis elbow
- Golfer’s elbow
- Plantar fasciitis
- Achilles tendinopathy
- Chronic low back pain
- Sacroiliac joint dysfunction
- Chronic neck pain
- Hip pain
- Ankle instability
- Ligament laxity
- Certain chronic sports injuries
Who Is a Good Candidate?
Patients may benefit from prolotherapy if they:
- Have chronic musculoskeletal pain lasting more than 3 months
- Have ligament or tendon injuries
- Have mild to moderate osteoarthritis
- Have persistent pain despite physiotherapy and medications
- Wish to avoid or delay surgery when appropriate
A thorough medical assessment is essential before treatment.
Dextrose Concentration Used
The concentration of dextrose depends on the tissue being treated.
Typical concentrations include:
- 12.5% dextrose: Commonly used for tendons and ligaments
- 15–25% dextrose: Often used for intra-articular (joint) injections
The concentration and treatment plan should always be determined by the treating physician.
Typical Injection Volumes
The injected volume varies depending on the treatment area.
General ranges include:
- Small tendon or ligament: 0.5–2 mL per treatment point
- Medium joint: 2–5 mL
- Large joint (knee, shoulder, hip): 5–10 mL
Multiple sites may be treated during the same session if clinically appropriate.
Equipment Used
A prolotherapy procedure is performed using sterile medical equipment, including:
- Sterile gloves
- Antiseptic skin preparation solution
- Sterile syringes
- Sterile injection needles selected according to the treatment site and tissue depth
- Dextrose solution
- Local anesthetic (when appropriate)
- Ultrasound guidance (recommended for many anatomical sites to improve accuracy)
Procedure Overview
A typical prolotherapy session includes:
- Medical evaluation and diagnosis.
- Discussion of benefits, risks, and informed consent.
- Positioning of the patient.
- Sterile skin preparation.
- Identification of the target structure, often with ultrasound guidance.
- Injection of the prescribed dextrose solution.
- Observation for a short period after the procedure.
- Discharge with home-care instructions.
Treatment sessions usually last 15–30 minutes.
Benefits of Prolotherapy
Potential benefits include:
- Reduced chronic pain
- Improved joint stability
- Increased collagen formation
- Better mobility
- Improved physical function
- Minimally invasive treatment
- Short recovery time
- May delay or reduce the need for surgery in selected patients
Possible Side Effects
Most side effects are mild and temporary.
These may include:
- Injection site soreness
- Mild swelling
- Temporary stiffness
- Bruising
- Minor bleeding
Rare complications include:
- Infection
- Allergic reaction
- Nerve injury
- Blood vessel injury
Contraindications
Prolotherapy may not be appropriate for patients with:
- Active infection
- Uncontrolled bleeding disorders
- Allergy to treatment components
- Certain uncontrolled medical conditions
- Pregnancy in selected situations, depending on the treatment area and clinical judgment
Home Medications
After prolotherapy, the treating physician may recommend oral medications if needed.
Common options include:
- Acetaminophen (Paracetamol) for mild to moderate pain
- Tramadol for shortn term management of moderate pain in selected patients
- Codeine-containing analgesics for selected patients when clinically appropriate
Because prolotherapy depends on a controlled inflammatory healing response, many clinicians recommend avoiding nonsteroidal anti inflammatory drugs (NSAIDs) for several days after treatment unless they are medically necessary.
Examples include:
- Ibuprofen
- Naproxen
- Diclofenac
Patients should only take medications prescribed or approved by their healthcare provider.
Home Care Instructions
Patients are generally advised to:
- Rest the treated area for 24–48 hours.
- Avoid strenuous exercise for several days.
- Resume light daily activities as tolerated.
- Follow the prescribed rehabilitation or physiotherapy program.
- Maintain adequate hydration.
- Attend scheduled follow up appointments.
Seek immediate medical attention if fever, severe swelling, increasing redness, drainage, or worsening pain develops.
Recovery
Most patients experience mild soreness for 24–72 hours after treatment.
Healing is gradual, and improvement may continue over several weeks or months. Many patients require 3–6 treatment sessions, depending on the condition being treated and their clinical response.
Is prolotherapy painful?
Most patients experience mild discomfort during and after the injection. Temporary soreness is common and usually resolves within a few days.
How many sessions are required?
Many patients require 3–6 sessions, although the number varies depending on the condition and individual response.
Is prolotherapy safe?
When performed by a trained healthcare professional using sterile technique and appropriate patient selection, prolotherapy is generally considered safe.
Can prolotherapy replace surgery?
In some patients, prolotherapy may improve symptoms enough to delay or avoid surgery. However, it is not a replacement for surgery in every condition.
Key Takeaway
Prolotherapy is a regenerative treatment that uses concentrated dextrose injections to stimulate healing in ligaments, tendons, and joints. It may reduce chronic pain, improve joint stability, and enhance function in carefully selected patients. Treatment should be performed by qualified healthcare professionals after a thorough medical evaluation, with appropriate follow up and rehabilitation.
