Cell Therapy Injections for Knee & Joint Pain
Cell therapy injection is a powerful form of medical care that uses cells to treat knee and joint problems. Popular cell therapies for knee pain include mesenchymal stem cells, bone marrow and platelet rich plasma. Studies have tied cell therapy to improvements of up to 73% in knee pain and disability.
What Is a Cell Therapy Injection for Knee or Joint Pain?
Cell therapy injections use live human cells to replace or repair damaged cells and tissues. Orthopedic cell therapy injections apply this principle to the cartilage, muscles and tissues in the knees, hips and other joints. Doctors commonly inject bone marrow concentrate and/or platelet rich plasma in these areas. Cell therapy has successfully helped patients suffering from common forms of joint pain.
How Does a Cell Therapy Injection Work?
Cell therapy treatments work by replacing or enhancing damaged or missing cells and tissues in the knee or other joints. The specific mechanism of action varies depending on the type of cell therapy used.
Cell therapy injections generally do not provide immediate pain relief or symptom improvement. This is because cell therapy results depend on biological processes that span weeks to months. Instead, patients often notice pain relief and other benefits 2 to 6 weeks after treatment.
You can understand this better by considering the nature of conditions treated by cell therapy. Knee pain often appears after years of biological and physical damage and/or failure. Cell therapy injections are intended to address some of these long-term problems at the root. Since this requires overcoming months or years of damage, it makes sense that results take time.
Results: How Much Does a Cell Therapy Injection Help Knee Pain?
In one study, cell therapy decreased knee pain by about 75% within 6 months of treatment. The study investigated the effects of bone marrow cells on arthritic knee pain. Knee pain from arthritis, also called osteoarthritis, affects millions of people worldwide.
Knee Pain Relief From Bone Marrow Containing Mesenchymal Stem Cells
Time Period: 6 months
# Treatments: 1
Improvement in Knee Pain: 75%
Improvement in Knee Function: 35%
In the study, patients with arthritic knee pain had one injection of bone marrow cells. Researchers tracked the patients’ pain and knee function scores. At six-month follow-up, patients still in the study had about 75% improvement in pain. They also had about 35% improvement in knee function.
Cell therapy treatment results can vary depending on several factors. These include the severity of injury, the type of cell therapy used and patient health. The results seen in this study may not be typical. But patients interested in cell therapy for joint pain should discuss it with a specialist. A regenerative medicine doctor can help patients understand what this type of treatment may do for their individual case.
Benefits of a Cell Therapy Injection for Knee or Joint Pain
Cell therapy injection benefits can vary based upon the type of treatment, the area treated and patient factors. Cell therapy joint injections can provide several potential benefits, including:
Cell therapy injection patients may not experience all of the above benefits. Patients weighing the benefits of cell therapy joint injections should discuss this procedure with a physician. The physician can explain how a cell therapy injection may or may not benefit the patient.
Side Effects of Cell Therapy Injections in Knees or Joints
As with all medical procedures, cell therapy injections in the knee or other joints may cause side effects. In one knee injection study, none of the patients reported a significant side effect. But other studies reported mild side effects like injection site pain and temporary soreness at the blood or bone marrow draw site.
In rare cases, patients may develop inflammation or infection of the treated tissue. According to medical literature, this side effect is quite rare. Doctors can generally manage this side effect with steroids and/or antibiotics.
Another fairly common side effect is a vasovagal response during injection. This occurs when the patient’s heart rate slows and blood vessels relax, causing them to faint. Vasovagal episodes are generally brief and considered.
Eligibility for Cell Therapy Injections in the Knees or Other Joints
Eligibility for cell therapy injections in the joints can depend on several factors including the specific condition, its severity, and the patient’s goals. Patients considering cell therapy for knee pain should speak with a regenerative medicine doctor.
Selected Eligibility Criteria for Cell Therapy Injections in Knees & Other Joints
The following factors may make a patient eligible for injection-based cell therapy:
A confirmed diagnosis of arthritis/osteoarthritis
Active symptoms of arthritis for at least three months
Unsatisfactory outcomes of conservative arthritis treatments
The following factors may make a patient ineligible for cell therapy:
A history of bone or blood cancer within the last 12 months
A history of blood or bleeding disorders
An active infection
Severe cardiac or pulmonary disease
Recent steroid injection of the affected joint
Cell Therapy Procedures for Knee and Joint Pain
Joint pain can come from many different conditions. Studies show some knee and joint conditions have responded to cell therapy injections. Conditions treated with cell therapy injections include:
Doctors may use cell therapy procedures to treat any of the above conditions. In these procedures, doctors typically inject some form of cell therapy into the affected tissue. Specific procedures include:
Cell therapy joint injections often take place in a doctor’s office. They are minimally invasive and generally well-tolerated. So patients usually do not have to take time off from work or their regular lives to accommodate them.
Procedure Details: What to Expect From a Cell Therapy Injection for Joint Pain
Cell therapy injection procedures will vary due to the injection location, the type of therapy and physician preferences. However, cell therapy injections for joint pain do share a few common features.
1: Consultation Appointment
Before a doctor prescribes BMC or PRP, they will evaluate the patient for eligibility. This evaluation includes a general physical in addition to examination of the patient’s symptoms. Often, the patient already has a diagnosis at this point. In such cases, the consultation appointment gives the doctor a chance to look over x-rays or MRI reports. These imaging records help the doctor determine if cell therapy may be a good fit for the patient’s condition. If the patient is eligible, they will generally schedule a treatment appointment for a few days later.
2: Pre-Treatment Preparation
Before undergoing treatment, many doctors recommend patients stop taking NSAIDS. NSAIDs are non-steroidal anti-inflammatory drugs like ibuprofen and naproxen. They may limit the efficacy of cell therapy injections. Doctors may ask patients to avoid NSAIDs for the five days leading up to the procedure. During this time, patients may also need to withhold or limit doses of blood thinners. Patients should only alter their dosage of prescribed medications at the specific request of a licensed physician.
3: Cell Therapy Injection for Joint Pain
During the cell therapy injection appointment, the procedure generally includes the steps below.
4: Recovery and Rehabilitation
Cell therapy injections can achieve powerful results, but these results take time. After a cell therapy injection for joint pain, doctors often advise patients to limit activity for a week or two. After this time period, doctors may also suggest working with a physical therapist. A physical therapist can help the patient provide mechanical signals that help the cell therapy work as effectively as possible.
