Non-Surgical Options for Managing Knee Osteoarthritis
Are You a Regenexx Candidate?Knee osteoarthritis (OA) is one of the most common orthopedic conditions. For individuals experiencing this condition, the associated discomfort may affect activity levels and overall well-being.
Typically, when individuals over 40 experience knee discomfort due to osteoarthritis—often referred to simply as arthritis—medical advice often points toward conservative measures. These measures can include physical therapy, anti-inflammatory medications, or injections of corticosteroid or hyaluronate to help manage inflammation and discomfort.
If these initial approaches do not result in improvement, surgery may be considered to address damaged cartilage or tissue. Should symptoms persist even after these interventions, a total knee replacement is frequently presented as the subsequent treatment option.

Can Knee Surgery Help Reduce Pain?
Studies[2] evaluating the outcomes of typical orthopedic knee surgeries suggest that these procedures may offer limited benefit, especially for individuals over the age of 40. Even in younger patients, success is not universal. Patients should understand that surgery may not always be the most recommended solution.
Read on to learn more about the Regenexx approach at Pain Doctors Medical in Newark, NJ, which offers an alternative to knee replacement surgery for osteoarthritis. These procedures utilize interventional orthobiologics to may support the body’s natural healing response. They may help reduce discomfort and improve function. Treatment is delivered by physicians in the licensed Regenexx network and is customized to individual needs.

How Does the Regenexx Approach Work for Knee Osteoarthritis?
Physicians in the licensed Regenexx network at Pain Doctors Medical in Newark, New Jersey, utilize Regenexx procedures as part of an approach called interventional orthobiologics. This minimally invasive option compared to knee surgery uses image-guided injection of the individual’s own bone marrow concentrate directly into the joint.
The healing agents in the concentrate may support the body’s natural healing response at the injury site and may help reduce the need for surgery.
The Regenexx Approach for Knee Arthritis
Physicians in the licensed Regenexx network at Pain Doctors Medical in Newark, New Jersey, conduct a thorough evaluation of movement patterns and may use ultrasound imaging to view the joint’s internal structures in real time. This approach provides a clearer understanding of the cause of pain, how joint function is impacted, and what underlying issues are contributing to the condition.
Following this evaluation, the physician will develop a customized treatment plan. Recommended procedures may include:
- Regenexx SD Injectate – A procedure using bone marrow concentrate, which contains regenerative cells, prepared according to Regenexx intellectual property.
- Regenexx SCP Injectate – A proprietary formulation of platelet-rich plasma (PRP) that is more concentrated than PRP produced by typical bedside centrifuge devices.
- Regenexx PL Injectate – Platelet lysate, a specialized derivative of platelet-rich plasma (PRP).

Changes Observed in MRI Images
The MRI images provided below illustrate the changes observed in two individuals who underwent procedures using Regenexx injectates for knee osteoarthritis.
To view the knee joint before the procedure, scroll the arrow to the right. The white or lighter areas within the joint space may visually indicate regions of joint degeneration. To view the MRI of the knee joint following the procedure, scroll the arrow to the left.
Patient 1 MRI: 51 years old
Patient 2 MRI: 46 years old
Patient 1:
This individual experienced limited improvement following a microfracture procedure and had difficulty resuming many daily activities. A procedure using an injection of autologous cells processed using Regenexx lab methods was later performed. Following the procedure, the individual reported returning to routine functional activities.
Patient 2:
This individual underwent arthroscopic debridement. Approximately 1.5 years after surgery, the individual received a procedure involving autologous cells processed using Regenexx lab methods. Subsequent to the procedure, the individual reported resuming full functional activities.
Patient FAQs
The knee is a joint, and it is the largest one in the body. It is the point where the thigh bone (femur) connects with the shin bones (tibia and fibula). The ends of these bones are covered with a smooth, slippery tissue called cartilage, which may help reduce friction within the joint. This surface allows the bones to move against one another more easily and may help protect the joint from stress. The knee also contains two crescent-shaped pieces of fibrous cartilage called the meniscus. These structures contribute to joint stability and help distribute weight more evenly.
Over time, the knee joint is subjected to significant stress during weight-bearing activities. Like all joints, it goes through natural cycles of wear and repair, which can include cartilage thinning, the development of bone spurs, and other structural changes. In some cases, the body’s repair response can alter the joint’s shape or alignment. When this occurs, the bones may not remain properly aligned or adequately lubricated. Over time, this may lead to inflammation, pain, swelling, and stiffness, which are often associated with a condition called osteoarthritis. Contributing factors may include excess body weight, the natural aging process, or previous injury to the joint.
How is osteoarthritis different from other types of arthritis?
Arthritis is a general term used to describe inflammation of the joints. There are two primary types of arthritis:
- Osteoarthritis (OA) – also referred to as degenerative joint disease- is the most common form of arthritis. It occurs when the cartilage within a joint gradually wears away, commonly affecting the hips, knees, and spine.⁶
- Rheumatoid arthritis (RA) – is an autoimmune condition in which the immune system mistakenly targets the lining of the joints (synovium), resulting in inflammation and joint damage.⁷
Yes. An analysis of our data indicates that individuals with less advanced arthritis experienced similar outcomes to those with bone-on-bone arthritis. This observation is also supported by findings published by other researchers.⁸
Both X-rays and magnetic resonance imaging (MRI) can reveal changes in the joints associated with degenerative arthritis. However, symptoms of osteoarthritis may appear before visible damage is detectable on standard X-rays. For this reason, physicians often rely on MRI, which is more sensitive for identifying early signs of osteoarthritis. Additionally, MRI provides three-dimensional imaging, offering more detailed views compared to traditional X-rays.
Although cartilage plays a key role in joint function, its loss is not typically the direct source of pain. The MRI finding most consistently linked with pain is swelling within the bone, known as bone marrow edema (BME) or a bone marrow lesion (BML). Recent research on knee pain related to arthritis has shifted focus from cartilage deterioration to the presence of bone marrow swelling.
No, they will not regenerate large areas of cartilage; however, they may help:
- Replenish diminished cellular reserves. The body’s natural supply of cells involved in repair and maintenance tends to decline with age and the progression of arthritis.
- Support cellular recovery. Research suggests that mesenchymal stem cells may transfer healthy mitochondria to neighboring cells with damaged mitochondria, potentially restoring function in those cells.
- Address bone lesions. Emerging evidence indicates that microfractures, rather than cartilage loss, are a primary contributor to pain.
- Modulate the joint environment. Arthritic joints often contain a mix of inflammatory and catabolic substances, and cellular therapies may help shift the environment toward one that is more supportive of tissue maintenance.
