Stem Cell Program for Knee Osteoarthritis (Chondrogenic MSC): What Is It? Does It Really Work, and What Should You Know Before Treatment?

Knee osteoarthritis (Osteoarthritis: OA) is a condition in which the cartilage covering the surface of the knee joint gradually deteriorates or becomes thinner. As the cartilage wears down, the bones within the joint may begin to rub directly against each other, leading to inflammation, knee pain, swelling, stiffness, and difficulty with movement.

Knee osteoarthritis can result from several factors, including ageing, genetic conditions, excess body weight, prolonged heavy use of the knee joint, or previous knee injuries. The severity of knee osteoarthritis is commonly divided into 4 stages:

• Stage 1: Early stage — The cartilage begins to show mild wear, but there may be no obvious pain. Most individuals can continue their normal daily activities.
• Stage 2: Mild stage — The cartilage covering the knee joint begins to thin in some areas. Mild pain may occur, and clicking or cracking sounds may be heard from the knee.
• Stage 3: Moderate stage — Cartilage degeneration becomes more pronounced, and inflammation may develop within the joint, leading to chronic pain and swelling, stiffness, and increasing difficulty with movement.
• Stage 4: Severe stage — The cartilage is severely damaged, allowing the bones within the joint to rub directly against each other. This can cause severe knee pain, limited ability to fully bend the knee, and, in some individuals, joint deformity and significant loss of mobility.

Chondrogenic MSC refers to a type of Mesenchymal Stem Cell (MSC) with characteristics directed toward cartilage cells. These cells are derived from umbilical cord tissue, particularly the gelatinous substance known as Wharton’s jelly, which is rich in MSCs capable of differentiating toward cartilage-related cells and supporting tissue recovery.

After a doctor injects Chondrogenic MSCs into the knee joint, the cells may act through several mechanisms. These include stimulating the body’s own cartilage cells (Endogenous Cartilage Cells) to proliferate and help replace damaged or degenerated cartilage and ligament-related tissues, while also releasing proteins and bioactive substances involved in tissue repair. In addition, these cells may help regulate inflammation within the knee joint.

The main goals are to help relieve pain and support recovery of knee-joint function. However, Chondrogenic MSC injection is considered one option for supporting knee recovery without surgery and is not a standard first-line treatment. A doctor should assess each patient individually before treatment, and outcomes may vary depending on multiple factors.

Chondrogenic MSC is a knee-joint rehabilitation program that involves injecting stem cells directly into the affected area without surgery. It may be suitable for individuals who want to support the recovery of degenerative joint and tendon conditions, including:

• Individuals with knee osteoarthritis or degenerative joint conditions.
• Individuals with certain bone-related conditions.
• Individuals with chronic joint or knee pain who have already tried medications, physical therapy, or other approaches without sufficient improvement.
• Individuals with injuries involving the acromioclavicular joint.
• Individuals with knee injuries.
• Individuals seeking an additional option to support knee-joint recovery alongside other rehabilitation strategies, such as weight management, pain-relief medications, and appropriate lifestyle modifications.

For optimal outcomes and safety, it is important to consult a doctor before deciding to undergo knee stem cell injection. The doctor will assess several factors, including the severity of knee osteoarthritis, age, overall health, coexisting medical conditions, and the expected outcomes after stem cell treatment.

• Chondrogenic MSC injection is a medical procedure that requires strict quality control. It should therefore be performed at a reputable clinic that meets appropriate standards, uses high-quality stem cells with a verifiable source, and is carried out only by an experienced physician.
• Chondrogenic MSC is only one supportive approach for cartilage and joint recovery under appropriate individual conditions. It cannot replace standard medical treatment, particularly in patients with severe or advanced knee osteoarthritis.
• Individual responses and outcomes may vary depending on several factors, including the severity of knee osteoarthritis, age, overall health, underlying medical conditions, and individual aftercare.
• Although Chondrogenic MSC injection performed at a properly standardized clinic by an experienced physician is generally considered a relatively low-risk procedure, some side effects may still occur, such as pain or swelling at the injection site. Some individuals may also experience fatigue or a mild fever. These symptoms are usually temporary and often resolve on their own.

Knee stem cell injections for osteoarthritis, when performed by an experienced physician, are generally considered to carry a relatively low level of risk because they do not require surgery. In addition, the stem cell products used at LINNA Clinic undergo strict quality-control procedures, including assessment of cell characteristics, proliferative capacity, and cell viability of more than 95%. They are also tested for contamination and safety, together with assessments related to the potential risk of tumor or cancer development, to help ensure that the cells used meet appropriate quality standards.

However, individuals considering knee stem cell injections should choose a reputable clinic that follows appropriate medical standards, provides a thorough health assessment, and develops an individualized treatment and recovery plan under the supervision of an experienced physician to support both safety and optimal outcomes.

In general, the steps for using Chondrogenic MSC injections to support knee osteoarthritis care are as follows:

• Comprehensive medical assessment – The doctor reviews the patient’s medical history, performs a physical examination, and evaluates the severity of knee osteoarthritis in order to develop an appropriate treatment and recovery plan.
• Preparation of stem cells – High-quality Chondrogenic MSCs that meet established safety and quality standards are selected for use.
• Direct injection of Chondrogenic MSC into the knee joint – The number of stem cells used may vary depending on the severity of the condition in each individual case.
• Follow-up every 3 months after injection – The doctor assesses symptoms and the body’s response to treatment. Depending on the individual condition and medical assessment, the treatment may be repeated approximately every 6 months.
