By Dr. Vladimir Fiks, MD | Interventional Pain Management, Advanced Pain Management Center
Knee pain stops Portland patients from hiking Forest Park, cycling the Springwater Corridor, or simply getting through the workday. Before you consider surgery, there is a regenerative option that works with your body’s own biology. Regenexx at Advanced Pain Management Center offers a precise, evidence-informed alternative for patients ready to address the root cause of their knee pain.
Who Is a Candidate for Regenexx Knee Treatment?
Not every knee condition responds to the same treatment. Dr. Fiks evaluates each patient individually, but Regenexx has shown particular promise for three categories of knee conditions:
Knee osteoarthritis is one of the most common causes of chronic knee pain, involving progressive cartilage breakdown and bone-on-bone friction that causes stiffness, swelling, and limited mobility. It is especially common in patients 45 and older. Rather than masking the pain with cortisone injections, Regenexx BMC (bone marrow concentrate) targets joint degeneration at the cellular level, delivering the body’s own healing cells directly into the affected joint.
Meniscus tears, whether from sport and trauma or from gradual age-related wear, are another strong candidate condition. Regenexx PRP and BMC injections support tissue repair in both acute and degenerative tears, giving patients a meaningful option to explore before committing to meniscectomy.
Ligament injuries, including partial ACL, MCL, and LCL tears, as well as chronic laxity that has not yet reached the threshold for surgery, can also benefit from Regenexx. The regenerative approach provides a prolotherapy-style stimulus to ligament tissue, supporting repair without surgical intervention.
Dr. Fiks uses ultrasound and fluoroscopic guidance for all intra-articular knee injections, ensuring precise delivery to the target structure.
How Regenexx Works for the Knee
The Regenexx process begins with either a blood draw or a bone marrow aspiration, depending on the protocol best suited to your diagnosis. The sample is processed on-site using advanced concentration techniques, then injected directly into the affected knee structure under image guidance.
This is a meaningful distinction from a standard cortisone injection. Corticosteroids reduce inflammation temporarily, which can provide real relief, but they do not address the underlying structural damage. Regenexx aims to restore tissue integrity by delivering concentrated healing cells to where the damage exists. For patients who have cycled through multiple steroid injections without lasting improvement, this difference matters.

What to Expect: Recovery and Results
Regenexx is performed as an outpatient procedure. Most patients return to light activity within a few days, and integration of physical therapy is strongly recommended to support and extend the results. Improvement is not instant. Because regenerative therapy works by stimulating the body’s natural repair processes, benefits typically build over a 3 to 6 month window.
Honest framing is part of how Dr. Fiks practices. Patients with mild-to-moderate osteoarthritis tend to respond best. Severe bone-on-bone degeneration may require a more thorough evaluation to determine whether regenerative therapy is appropriate or whether additional options should be considered alongside it.
Why Choose APMC for Knee Regenerative Therapy in Portland?
Advanced Pain Management Center brings a level of interventional precision that matters when the treatment depends on accurate delivery. Dr. Fiks’s expertise in image-guided injections, developed across years of managing complex spine and joint conditions, is directly applicable to regenerative knee care. The APMC team is multilingual and serves patients throughout the greater Portland metro area, including Beaverton, Tigard, Hillsboro, and Lake Oswego.
Patients choosing APMC for Regenexx knee therapy are choosing a practice that already understands the architecture of pain, not one that is new to interventional care.
Frequently Asked Questions
Is Regenexx covered by insurance for knee pain?
How many Regenexx knee injections will I need?
This depends on the severity and type of your condition. Dr. Fiks typically evaluates your response after an initial treatment series before recommending any additional injections.
Is Regenexx better than a cortisone shot for knee arthritis?
Cortisone reduces inflammation and can provide short-term relief, making it a useful treatment option in the right clinical setting. Regenexx targets the underlying tissue damage rather than the inflammatory response, which is why patients with chronic conditions often find it offers more durable improvement. The two approaches are not mutually exclusive, and Dr. Fiks will recommend what fits your clinical picture.
Can Regenexx help me avoid a knee replacement?
Many patients with mild-to-moderate knee osteoarthritis are appropriate candidates for regenerative alternatives to surgery. Regenexx is not a guarantee against surgery, but for the right patient, it can significantly reduce pain and improve function without an operation. Dr. Fiks evaluates each case individually.
How long does a Regenexx knee procedure take?
The procedure is typically completed within a few hours on an outpatient basis, including preparation and recovery time before you leave the clinic.
