This article will cover information on Prolotherapy including general questions on Prolotherapy treatments, side effects and research

  • Prolotherapy is a regenerative injection treatment used to repair incomplete healing of the ligament and tendons.
  • Prolotherapy is considered a viable alternative to surgery, as an option to pain medications and anti-inflammatory injections such as cortisone and other steroidal injections in instances of joint instability and osteoarthritis.
  • Prolotherapy is considered a safe, affordable option that allows the patient to keep working and/or training during treatment.

Prolotherapy for Ligament and Tendon Injury and Cartilage Regeneration

Chronic pain from joint instability involve strains and sprains to tendons and ligaments and resulting cartilage deterioration. Because ligaments and tendons generally have a poor blood supply, incomplete healing is common after injury. 

This is where comprehensive Prolotherapy comes in – pain is coming from joint instability – joint instability is coming from weakened and damaged ligaments and tendons as well as deteriorated cartilage. Comprehensive Prolotherapy through a series of injections REBUILDS the joints from within.

When cartilage is degenerated, the force to the bone is greater and uneven and arthritis develops. Since cartilage decreases the force inside the joint, it becomes obvious that as cartilage deteriorates as we age, other structures are going to have to bear this force. Since tendons move the joints and ligaments stabilize the joints, it is primarily these soft tissue structures that are involved. Because ligaments stabilize the joints, a weakening of these structures causes a further force to the bones of the joints. This increased force hastens the arthritic process.

What is in Prolotherapy Injections?

The primary ingredient in Prolotherapy injections used at Caring Medical is dextrose, a corn extract. How does a corn extract accelerate healing?

When a joint becomes injured, the cells in that area burst and release dextrose and trigger an influx of inflammatory cells, initiating the wound-healing system to the specific area.

In this basic Prolotherapy injection solutions, we also use an alkaline extract of the pitcher plant called Sarapin. Almost all pain issues have some kind of nerve component, which Sarapin helps to relieve. In our experience, Sarapin enhances the healing effects of injection treatments and has an excellent safety profile. It is one of the few materials found in the Physicians’ Desk Reference that has no known side effect. Also in the basic solution, to help ease the pain of the injection procedure, as well as provide pain relief to the area, procaine or lidocaine is added in very small quantities. Often, this helps to ease the pain right away after the procedure, but is used in such a small amount to not cause any adverse effect to the joint repair/wound healing cascade.

When a stronger inflammatory reaction is desired, additional natural ingredients can be used in the dextrose-based injections. These can include mineral additives, such as zinc or manganese. Another common Prolotherapy additive includes fatty acids, which increase the inflammatory effect. Lastly, certain hormones, including human growth hormone or testosterone, can be helpful for triggering localized repair of damaged tissue.

Cellular Prolotherapy – Stem Cell Therapy and Platelet Rich Plasma Therapy

As regenerative medicine advances, Prolotherapy practitioners are taking notice of which methods can be incorporated into dextrose Prolotherapy treatments to help direct a person’s own stem cells and/or growth factors into the exact places where healing needs to take place within a joint. This is called Autologous Prolotherapy, or Cellular Prolotherapy. In our office, we utilize Platelet Rich Plasma (PRP) Prolotherapy, which involves concentrating platelets/growth factors found in the blood and injecting them directly into the joint. We also offer Stem Cell Prolotherapy using a person’s own bone marrow and/or fat cells, which are collected and injected during the same day procedure. With any Cellular Prolotherapy procedure done in our office, patients also receive dextrose Prolotherapy to the surrounding joint attachments, in order to ensure the area of pain and instability is comprehensively treated.

Finding the source of your joint pain is crucial in Prolotherapy

The greatest stresses to the ligaments and tendons are where they attach to the bone, the fibro-osseous junction. The most sensitive structures that produce pain are the periosteum (covering of the bone) and the ligaments. It is important to note that in the scale of pain sensitivity (which part of the body hurts more when injured), research notes that the periosteum ranks first, followed by ligaments, tendons, fascia (the connective tissue that surrounds muscle), and finally muscle.1

Articular cartilage contains no sensory nerve endings. If you are told that your cartilage is the cause of your pain, that is not possible and is, actually, quite ridiculous. The periosteum is the most sensitive area to pain and the ligaments second. It is now easy to understand why this area hurts so much. This is where the Prolotherapy injections occur and thus eliminate the chronic pain of many conditions including arthritis, mechanical low back pain, Degenerative Disc Disease, cartilage injury, and, of course, sports injuries.

A discussion of Prolotherapy as surgery option for cartilage deterioration

Most of the joints in the body are synovial joints, or freely movable joints. These joints function as a result of the unique properties of the articular cartilage that covers and protects the ends of the bones. If the cartilage is damaged or removed, so is the functioning of the joint, which suffers as bone rubs against bone instead of cartilage over cartilage.

Surgery can be broadly classified into open repair, in which a surgical incision is made for direct access and visualization of the injury site, and closed, or arthroscopic, repair, in which a miniature camera is used to look into the joint through a small hole, and specially designed tools are used to repair the tissue. Surgery almost always involves the removal of bone, ligaments and tendons. Many different types of surgery are common, including:

  • rotator cuff surgery: arthroscopic surgery done to clean scar tissue and damage to the joint surfaces, as well as repair the tear of the rotator cuff
  • hip replacement: replacement of the joint in which the diseased bone tissue and cartilage is removed from the hip joint, replacing the head of the femur (the ball) and the acetabulum (the socket) with new, artificial parts; the healthy parts of the joint are left intact. Learn more about Prolotherapy as a hip replacement alternative.
  • knee surgery, also called arthroscopy: although intended to “explore” the knee joint to determine the cause of the problem, it usually involves some scraping, burning and/or cutting of valuable cartilage
  • laminectomy: the most common back surgery, which involves the surgical removal of the posterior arch of a vertebra; results in problems similar to those of a discetomy (see below)
  • lumbar spinal fusion: fuses vertebrae together, which often leads to ligament laxity and spinal instability as other parts of the spine attempt to compensate for this new, rigid section
  • ankle fusion: similar to a spinal fusion, it fuses the shinbone to the talus, immobilizing an area to eliminate pain, but often leading to more pain due to ligament laxity and compensation in other areas and joints
  • discectomy: a disc is removed to alleviate lower back pain; this often results in more back pain as the surgery causes ligament laxity and instability of the spine

Reasons patients avoid surgery:

  • Surgery is traumatic; it puts stress on the body and could cause the individual to feel less confident using the surgerized limb.
  • Surgery irreversibly alters the individual’s anatomy.
  • Surgery potentially involves all kinds of complications.
  • Surgery can lead to long-term arthritis due to the removal of significant tissue that is needed to help the body bear weight, such as cartilage, meniscus and disc tissue.
  • Rehabilitation is much longer after surgery than for more conservative measures, such as Prolotherapy.
  • Surgery does not always resolve the pain, which either means it did not address the cause of the pain, or that it caused another problem.
  • Because there’s a better way…Prolotherapy.

The ideal Prolotherapy candidate has the following:

  1. Pain originating from a ligament or tendon
  2. Strong immune system
  3. Willingness to improve and receive follow-up visits
  4. Healthy diet
  5. Positive mental outlook

Prolotherapy Treatment Goals

What are the goals of Prolotherapy treatments?

  • Function Is the patient’s ability to function in activities of daily living improved? Is the patient able to perform previously painful activities without pain? Is the person able to do things that he/she could not do prior to Prolotherapy?Patients are typically advised to continue to receive Prolotherapy treatments until able to stably perform that certain function pain and cracking-free. For example, if a patient can nowclimb two flights of stairs without knee pain after Prolotherapy, whereas prior to the Prolotherapy this would cause excruciating pain, then we know that Prolotherapy is helping improve function.
  • Strength Ligament and tendon injury may cause muscle strength to decline. When a person receives Prolotherapy, one of the noticeable effects of the treatment is that strength improves in the injected areas.
  • Pain Pain is one of the most common reasons patients receive Prolotherapy. Thus, a noticeable decrease in pain shows the  benefit of successful Prolotherapy.
  • Stiffness Patients commonly experience stiffness upon morning rising or after performing a certain activity. This stiffness is commonly felt in the lower back or neck, but could involve any area of the body. A great sign that Prolotherapy is working is that stiffness has subsided. Once Prolotherapy helps stabilize the area involved, the muscles no longer have to provide this stability so they relax. Once they relax, the stiffness subsides.
  • Physical Examination An experienced Prolotherapy doctor should be able to assess whether the Prolotherapy is working by simple physical examination. The physician can also listen for crepitation or crunching in the joints which can often be audibly heard by moving the joint. The joint that doesn’t crunch is also improving. X-rays and MRIs are poor indicators that Prolotherapy is working, the reason being that most ligaments do not show up well on these tests. Some improvements from Prolotherapy can be seen with x-rays and MRI’s, but it isn’t always necessary or advantageous to rely solely on those indicators due to their high incidence of inaccuracies.

The effectiveness of Prolotherapy

The effectiveness of Prolotherapy does depend upon the technique of the individual doctor, as well as the overall health and dedication of the patient to encourage the healing process after each treatment. For the patient who has localized areas of pain or the person who has had a recent injury from an accident, Prolotherapy is a very effective treatment to strengthen those specific areas and eliminate the pain. Realize, however, that Prolotherapy starts the growth of new healthy, strong tissue. Your body–your own immune system–grows the tissue. For the person who has terrible digestion, chronic fatigue, irritable bowel; and a host of other chronic nutritional, hormonal, allergic problems, these deficiencies and illnesses should be corrected so the body will be able to respond to Prolotherapy.

As with other medical procedures, Prolotherapy is a specialty. If you are looking into Prolotherapy, you first want to make sure that the Prolotherapy doctor in experienced in the Comprehensive Prolotherapy procedure and has successfully treated cases like yours. Someone who receives Prolotherapy does so with the hope of achieving complete pain relief.

There are several options available to the person who has a less than optimal results with Prolotherapy. At Caring Medical, we work with patients to investigate why they are not healing. It could be as simple as the prior Prolotherapy doctors’ technique was to give minimal injections and they did not receive enough Prolotherapy injections to the area. The same goes for patients who did not receive a strong enough Prolotherapy solution. We know what typically works best to get a patient a better Prolotherapy response.

In our office, it is common for us to get various referrals from other Prolotherapy doctors and have some of their patients see us.

Questions about Prolotherapy injections at the time of treatment

Questions about Prolotherapy injections at the time of treatment
To achieve a curative result with Prolotherapy, doctors should take a comprehensive approach, this will include multiple injections at each session, and enogh treatment to:

  • Stimulate all the structures that are injured to heal.
  • Use enough solution per structure to induce a sufficient healing reaction.
  • Use a strong enough solution per structure to induce a sufficient healing reaction.
  • Help the person obtain maximum health if their health is not good.
  • Assist the person in getting off medications, supplements, or traditional hormones (like birth control pills) that inhibit healing.

Pateint comfort during the Prolotherapy procedure is of course a great concern. Some people have many Prolotherapy injections and experience little discomfort, while others receive a few shots and experience more discomfort.

Caring Medical has many options to help patients lessen the pain of the injections

  • Lidocaine cream for the skin. This is applied shortly before treatment and helps to reduce the pain when the needle pierces the skin. The needle piercing through the skin is the most painful part of the procedure.
  • Pre-medication may be prescribed, such as Vicoden or Xanax to help you relax and dull the pain from the treatment.
  • Conscious sedation is an option for some patients.
  • Sometimes squeezing a stress ball is al that is needed

For those requiring Prolotherapy injections in many areas at one time or in very delicate areas like the neck, intravenous conscious sedation using demerol, a narcotic, may be used. The intravenous conscious sedation is the most dangerous part of the whole procedure. An occasional nausea and a few “upchucks” were the only side effects. The conscious sedation does make a person “woozy” and is typically preferred by patients who have pain throughout most of their body and getting many areas treated at once, such as Ehlers-Danlos patients, or in cases where the pain is very extreme in the area, such as in cases of Chronic Regional Pain Syndrome or RSD. Sometimes these patients prefer it because it eliminates the pain of the Prolotherapy injection treatment. For the most part, the Prolotherapy injections are completed in a matter of minutes and the patients do not require anything for pain during the treatment.

Most of our patients receive Prolotherapy without the help of medication and do just fine!

Prolotherapy Side effects and risks

Prolotherapy Side effects and risks

  • Bleeding in the area 
  • Bruising in the area
  • Increased pain
  • Infection
  • Joint effusion
  • Nerve injury
  • Puncture of a lung
  • Spinal headache
  • Stiffness
  • Swelling
  • Tendon/ligament injury

Because Prolotherapy causes inflammation, the person will often note some bruising, pain, stiffness and swelling in the area after receiving Prolotherapy. Typically this lasts 1 to 7 days. On rare occasions it lasts longer. Lasting longer is not necessarily bad, some people just inflame more easily. Since the treatment works by inflammation, lingering pain after Prolotherapy can be a sign of healing. If the pain is severe after Prolotherapy, then call the office where the Prolotherapy was done. Prolotherapy should not cause excessive, severe pain. Severe pain after Prolotherapy, especially accompanied by a fever, could indicate an infection. Infection after Prolotherapy is the most serious risk that we have seen.

The risk of infection after Prolotherapy is between 1 and 1000 to 1 and 10,000 procedures. The most common infection with Prolotherapy is an infection in the skin. This type of infection typically responds to an antibiotic taken by mouth. If a joint or blood infection results, then intravenous antibiotics will typically be needed for six weeks.

Since some of the risks with Prolotherapy relate to the actual technique done, it is important to go to a clinic with a lot of experience. Surely a doctor can stick a needle into a nerve, ligament, or tendon and cause injury. A doctor can stick the needle into the lung when doing the thoracic vertebrae or ribs. A doctor could also stick the needle into the spinal canal when doing any area of the spine and cause a cerebrospinal fluid leak. This is known as a spinal headache (which is a headache when you sit up). The risks of these side effects are rare, but do occur.

Prolotherapy for Knee Pain

Caring Medical doctors  investigated Prolotherapy in patients  with unresolved knee pain at a charity clinic in rural Illinois. Eighty patients, representing a total of 119 knees, were treated quarterly with Prolotherapy. On average, 15 months following their last Prolotherapy session, patients were contacted and asked numerous questions in regard to their levels of pain and a variety of physical and psychological symptoms, as well as activities of daily living, before and after their last Prolotherapy treatment. The results of this study showed that patients had:

  • Statistically significant decline in their level of pain, stiffness, crunching sensation, and improvement in their range of motion with Prolotherapy.
  • More than 82% showed improvements in walking ability, medication usage, athletic ability, anxiety, depression, and overall disability with Prolotherapy.
  • Ninety-six percent of patients felt Prolotherapy improved their life overall. 3

Other researchers have shown that Prolotherapy injections resulted in safe and substantial improvement in quality of life in knee osteoarthritis patients.4 Prolotherapy resulted in clinically meaningful sustained improvement of pain, function, and stiffness scores for knee osteoarthritis compared with blinded saline injections and at-home exercises.5 In other Caring Medical research, Dr. Hauser was able to document articular cartilage regeneration.6

In patients with symptoms of anterior cruciate ligament laxity and weakness, intermittent Prolotherapy injections resulted in clinically and statistically significant improvement in pain, swelling, and knee range of motion.

Prolotherapy and PRP (Platelet Rich Plasma) Injections for Knee Pain

Comprehensive Prolotherapy is an injection technique utilizing many healing factors. They can include or be used in conjunction with Dextrose, Blood Platelets, and stem cell injection therapy. The stem cells and blood platelets are drawn from the patient. In research, PRP by itself has been shown to be a remarkable treatment for knee osteoarthritis. However, other research points out that PRP’s effects may not be long lasting or beyond six months.8 At Caring Medical we developed comprehensive Prolotherapy and inject the supportive structures of the knee with dextrose Prolotherapy and other growth factors. Simply, while PRP can address and repair damaged cartilage, it is not addressing the ligament and tendon weakness that contributed to the cartilage deterioration. Comprehensive Prolotherapy seeks to repair the entire knee.

Prolotherapy and Stem Cell Therapy for Knee Pain

In this study, Caring Medical doctors examined the use of a simple, cost-effective regenerative treatment using direct injection of bone marrow stem cells into osteoarthritic joints in combination with dextrose Prolotherapy. Seven patients with hip, knee or ankle osteoarthritis received two to seven treatments over a period of two to twelve months. All patients reported improvements with respect to pain, as well as gains in functionality and quality of life. Three patients, including two whose progress under other therapy had plateaued or reversed, achieved complete or near-complete symptomatic relief, and two additional patients achieved resumption of vigorous exercise.9 For a more comprehensive article please see Knee Osteoarthritis treated with Stem Cell Therapy on this website.

Prolotherapy for Back Pain

Caring Medical patients are often surprised to learn that Prolotherapy can heal most disc problems in neck and back. While we talk about Prolotherapy healing joint pain that results from ligament and tendon injuries, most people are unaware that disc problems results from ligament injuries or instability along the spine. Patients with degenerative disc disease,herniated discs, bulging discs, bone on bone, etc can all be healed with Prolotherapy.

Prolotherapy works to stabilize the ligaments of the spine allowing discs to get back into position and can even create space to a person who has lost space due to one or more degenerated disc. In Prolotherapy research from the doctors of Caring Medical, patients with more than four years of unresolved low back pain were shown to have had their pain improved, stiffness, range of motion, and quality of life measures even 12 months subsequent to their last Prolotherapy session. 10 More information can be found on these pages on our site Prolotherapy for Chronic Low Back Pain.

Prolotherapy for Shoulder Pain

In published research from Caring Medical doctors, The optimal long-term, symptomatic therapy for chronic shoulder pain has not been established. Accordingly, we investigated the outcomes of patients undergoing Hackett-Hemwall dextrose Prolotherapy treatment for unresolved shoulder pain at a charity clinic in rural Illinois. We studied a sample of 94 patients with an average of 53 months of unresolved shoulder pain that were treated quarterly with Prolotherapy. An average of 20 months following their last Prolotherapy session, patients were contacted and asked numerous questions in regard to their levels of pain and a variety of physical and psychological symptoms, as well as activities of daily living, before and after their last Prolotherapy treatment. The results of this study showed that patients had a statistically significant decline in their level of pain, stiffness, and crunching sensations (crepitation). Prolotherapy, PRP, and Stem Cell Therapy have been used successfully in patients seeking alternatives to rotator cuff surgery. as well as patients with SLAP Lesions and Glenoid Labral Tears. Our treatments have also shown to be eeffective in helping patients who suffer from pain after shoulder surgery.
