Oregon Regenerative Medicine in Lake Oswego offers stem cell therapy for knees using autologous adipose tissue grafts. This Portland-area practice provides non-surgical regenerative options for knee osteoarthritis and soft tissue injuries. This guide covers micro-fragmented adipose tissue (M-FAT) injections, platelet-rich plasma (PRP) therapy, and prolotherapy. It explains how these treatments work, who is a candidate, and what to expect during your visit.
M-FAT Injections for Knee Repair
Micro-fragmented adipose tissue (M-FAT) is a regenerative therapy that uses small pieces of a patient's own fat tissue to support joint healing. At Oregon Regenerative Medicine, doctors harvest a small sample of adipose tissue from the patient's body. This tissue contains regenerative cells and signaling factors that help support the body's natural repair response. The graft is processed in-house and injected into the knee to address cartilage-related wear and tear.
How M-FAT Works in the Knee
Adult adipose tissue is the most abundant source of stem cells in the human body. Unlike embryonic stem cells, these adult cells are approved by the FDA for research and treatment of a wide variety of conditions. When injected into the knee, M-FAT helps calm inflammation and supports the repair of damaged connective tissue. This approach is often considered for patients with knee osteoarthritis who wish to avoid joint replacement surgery.
Candidate Selection and Safety
Not every patient with knee pain is a candidate for M-FAT injections. Doctors evaluate the severity of joint damage, imaging results, and overall health before recommending treatment. The procedure is non-surgical and allows patients to remain active during the treatment process. Recovery time is generally swift, enabling a return to daily activities sooner than with traditional surgical options.
PRP Therapy for Knee Pain
Platelet-rich plasma (PRP) is a concentrated sample of platelets derived from a patient's own blood. Platelets contain growth factors that help calm inflammation and support tissue repair. During PRP therapy, this concentrated solution is injected into the knee joint or surrounding injured tissue. PRP may be recommended for knee osteoarthritis, chronic tendon irritation, or soft tissue injuries that have not improved with rest or physical therapy.
The PRP Preparation Process
Oregon Regenerative Medicine prepares PRP in-house using advanced laboratory techniques. The blood sample is processed to concentrate platelets, which are rich in growth factors and biologically active proteins. This in-house preparation ensures the highest quality and purity of the biologic agent. The resulting solution is then injected under image guidance to ensure precise placement.
Image-Guided Precision
Accurate diagnosis and targeted injection are critical for successful outcomes. The practice utilizes four Sonosite ultrasound systems for comprehensive guided procedures. Ultrasound imaging is equal to or better than MRI in evaluating most tendon and ligament disorders in the arms and legs. For deeper structures, the clinic uses a state-of-the-art GE OEC One Flat Panel C-Arm system for fluoroscopy-guided injections. This technology allows clinicians to confirm needle position in real time, enhancing both procedural accuracy and patient safety.
Prolotherapy for Joint Stability
Prolotherapy is a non-surgical injection procedure that stimulates the body's wound repair cascade. It is designed to heal joints when other treatments fail by restarting innate repair mechanisms. Prolotherapy injections can result in permanent repair of damaged connective tissue, including ligaments and tendons. Depending on the injury, the addition of PRP or stem cell therapy can add powerful regenerative healing properties to the prolotherapy treatment.
Addressing Ligament Laxity
Ligaments stabilize bone-to-bone connections and contain densely embedded nerve sensors that provide pain and proprioception input. When overstretched, ligaments lose elasticity and become lax, leading to joint destabilization. Prolotherapy helps correct this destabilization by promoting tissue tightening and strengthening. This is particularly beneficial for patients with chronic knee instability or those who have been told their only solution is surgery.
Combining Therapies for Optimal Results
Regenerative medicine at Oregon Regenerative Medicine often involves a combination of therapies. Doctors may recommend prolotherapy alongside PRP or M-FAT grafts to address multiple aspects of knee dysfunction. This integrated approach ensures that both the structural integrity and the biological environment of the joint are supported. Patients can remain active during the treatment process, and recovery time is swift.
Treatment Comparison Table
| Treatment | Primary Mechanism | Best For | Recovery Time |
|---|---|---|---|
| M-FAT Injections | Regenerative cells and signaling factors from adipose tissue | Cartilage wear, osteoarthritis | Swift, non-surgical |
| PRP Therapy | Growth factors from concentrated platelets | Tendon irritation, mild to moderate OA | Swift, non-surgical |
| Prolotherapy | Wound repair cascade stimulation | Ligament laxity, joint instability | Swift, non-surgical |

Frequently Asked Questions
Is stem cell therapy for knees safe?
Yes, when performed by qualified practitioners using autologous (patient's own) tissue. Oregon Regenerative Medicine uses adult adipose tissue, which is approved by the FDA for research and treatment of a wide variety of conditions. The procedure is non-surgical and carries a low risk of complications.
How many treatments are needed for knee osteoarthritis?
The number of treatments varies depending on the severity of the condition and the specific therapy used. Some patients may require a single M-FAT graft, while others may benefit from a series of PRP or prolotherapy injections. Your doctor will develop a personalized plan based on your diagnosis and goals.
Does stem cell therapy replace the need for knee replacement surgery?
For many patients, regenerative therapies can delay or avoid joint replacement surgery. However, it is not a guaranteed cure for all cases. The goal is to reduce pain, improve function, and support non-surgical healing. Surgery may still be necessary for advanced cases, but regenerative options provide a less invasive alternative.
What is the difference between PRP and M-FAT?
PRP is derived from blood and contains concentrated platelets and growth factors. M-FAT is derived from fat tissue and contains regenerative cells and signaling factors. PRP is often used for tendon and mild joint issues, while M-FAT is typically used for cartilage-related wear and tear. Both are autologous and prepared in-house.
How long does recovery take after knee injections?
Recovery time is generally swift, and patients can remain active during the treatment process. Most patients return to daily activities within a few days. Specific activity restrictions may apply depending on the type of injection and the area treated. Your doctor will provide detailed post-procedure instructions.
Where is Oregon Regenerative Medicine located?
The practice is located in Lake Oswego, Oregon, on the Willamette River. It is situated inside The Foundry Building at Oswego Pointe, surrounded by the city's riverfront park system. This location provides easy access for patients in the Portland metro area.
Do I need a referral to see a doctor at Oregon Regenerative Medicine?
You can call to schedule an appointment directly. The practice welcomes patients who have been told their only solution is surgery or a life on pain medications. A consultation will help determine if regenerative medicine is the right fit for your specific condition.
