What is Knee Osteoarthritis?
Knee Osteoarthritis (KOA) is a common, long-term joint condition where the cartilage in your knee gradually breaks down. This cartilage usually cushions your bones and helps your knee move smoothly. As it wears away, bones start to rub together, causing pain, swelling, and stiffness.
KOA is progressive and currently has no cure, but it’s not just a normal part of getting older. While age increases your risk, many factors play a role in how KOA develops and progresses. Knowing this can help you take an active role in managing your condition and possibly slow its progression. By understanding these factors, you can make lifestyle changes and seek early interventions that may help.
Common Names and Pseudonyms for KOA
When searching for information about knee osteoarthritis, you might come across different terms that mean the same thing. Recognizing these can help you find the right information:
- Osteoarthrosis
- Degenerative Joint Disease
- Knee Arthritis
- Knee Degenerative Joint Disease
- "Wear-and-tear arthritis"
Understanding these synonyms can make medical information clearer and more accessible.
Causes and Risk Factors
KOA mainly happens because the articular cartilage in your knee wears down over time. Unlike some tissues, cartilage doesn’t heal well once it’s damaged, leading to more friction and stress in the joint.
Several factors can speed up cartilage breakdown or make you more likely to develop KOA:
- Age: Risk increases after age 45.
- Obesity: A BMI of 30 or higher puts extra stress on your knees.
- Previous Knee Injuries: Past injuries like fractures or ligament tears can lead to earlier or worse KOA.
- Repetitive Stress: Jobs or sports that involve lots of kneeling, squatting, or heavy lifting can damage cartilage.
- Genetics: Family history can increase your risk.
- Anatomical Abnormalities: Issues like "knock knees" can cause uneven wear.
- Gender: Women over 50 are more likely to develop KOA.
- Other Diseases: Conditions like rheumatoid arthritis, septic arthritis, psoriatic arthritis, or metabolic disorders can also contribute.
Recognizing the Symptoms and Impact on Daily Life
KOA symptoms usually start slowly and get worse over time. Common signs include:
- Pain: Worse with activity, better with rest, especially when bending the knee.
- Stiffness: Especially after sitting or sleeping.
- Swelling or Puffiness: The knee may look or feel swollen.
- Audible Sounds: Cracking, popping, or grinding when moving the knee.
- Instability: The knee may feel like it could give out or buckle.
- Reduced Mobility: Trouble with daily movements like getting up, climbing stairs, or walking for long periods.
As KOA progresses, you might also experience:
- Joint Instability: Pain can weaken muscles around the knee, making it less stable.
- Bone Spurs (Osteophytes): Extra bone growth can cause more pain.
- Baker's Cyst: Fluid buildup can form a cyst behind the knee.
KOA doesn’t just affect your body—it can also impact your mental health, leading to anxiety or depression. That’s why a holistic approach, addressing both physical and emotional well-being, is important.
How KOA is Diagnosed
Diagnosing KOA usually involves:
- Physical Examination: Your doctor will check for swelling, tenderness, range of motion, and stability, and watch how you walk.
- Imaging Techniques: X-rays or MRI scans help assess cartilage damage and bone spurs, providing visual confirmation of the diagnosis.
Stem Cell Therapy for Knee Cartilage Regeneration: An Overview
Introduction to Regenerative Medicine and its Promise
Regenerative medicine is a fast-growing field focused on helping the body heal itself. For people with knee osteoarthritis, where traditional treatments often only manage symptoms, regenerative therapies like stem cell therapy offer new hope. These treatments aim to actually repair joint damage and restore function, not just relieve pain.
The Science Behind Stem Cells: How They Aim to Heal
Stem cells are special cells that can turn into many different types of cells, including chondrocytes—the cells that make healthy cartilage. In knee osteoarthritis, stem cells are thought to help in several ways:
- Modulating the Local Environment: They reduce inflammation in the joint, making healing easier.
- Stimulating Endogenous Repair: They encourage your body’s own cells to repair damaged tissue.
- Anti-apoptotic Effects: They help prevent cell death in the joint.
- Mitotic Effects: They promote the growth of repair cells.
Rather than directly rebuilding cartilage, stem cells mostly help your body’s own healing processes. This means the goal is to reduce pain and improve function, not necessarily to regrow all lost cartilage.
Types of Stem Cells Used in Knee Cartilage Regeneration
Different types of stem cells are used for knee cartilage repair:
- Adult Stem Cells (Mesenchymal Stem Cells - MSCs): Most commonly used, found in bone marrow and fat.
- Bone Marrow-Derived MSCs: Taken from the pelvic bone, widely studied.
- Adipose Tissue-Derived MSCs: Taken from fat tissue, like the abdomen or thighs.
- Embryonic Stem Cells: Can become any cell type but are mostly used in research due to ethical concerns.
- Induced Pluripotent Stem Cells (iPSCs): Adult cells reprogrammed to act like embryonic cells; still experimental.
- Cord Blood Stem Cells: Used in products like Cartistem® in South Korea, these are donor-derived and surgically implanted.
It’s important to know the difference between autologous (your own cells) and allogeneic (donor cells) treatments. Autologous treatments are safer regarding immune rejection, while allogeneic treatments are more readily available but carry some risks.
Detailed Description of the Procedure: Injection vs. Surgical Implantation
Stem cell therapy for knees can be done in different ways, depending on your needs:
- Direct Injection: Stem cells are harvested from your bone marrow or fat, processed, and injected into your knee, often using ultrasound for accuracy. This is usually an outpatient procedure.
- Surgical Implantation: For more severe damage, stem cells may be implanted during surgery, sometimes with techniques like debridement (removing damaged tissue), microfracture (stimulating healing), or using scaffolds to support new tissue growth. Products like Cartistem® are administered this way.
The whole process can take 3 to 9 days, depending on the complexity. The choice of method depends on your specific condition and goals.
Current Scientific Consensus and Expert Recommendations
Stem cell therapy for knee osteoarthritis is promising but still debated among experts:
- Lack of Standardization and Inconsistent Evidence: Organizations like the American College of Rheumatology and the American Academy of Orthopaedic Surgeons do not currently recommend stem cell injections as standard treatment due to inconsistent evidence and lack of standardization.
- Mixed Efficacy Findings from Research: Some studies show slight improvements in pain and function, but the evidence is often rated as low certainty. While some patients report dramatic improvements, clinical trials usually show more modest benefits.
- Safety Profile: Autologous stem cell treatments are generally safe, but risks include infection, allergic reactions, cell rejection (with donor cells), contamination, and, rarely, tumor formation. The safety depends on proper preparation and sterile technique.
- Regulatory Status and Insurance Coverage: Regulations vary by country. South Korea has approved products like Cartistem® and has a progressive regulatory environment, but most insurance plans do not cover these treatments, so patients usually pay out-of-pocket.

- Cell rejection (with donor cells)
- Contamination (if not prepared properly)
- Tumor formation (very rare)
Choosing a reputable clinic with strict standards is essential for safety.
Setting Realistic Expectations for Treatment Outcomes
Stem cell therapy is not a cure for knee osteoarthritis or a way to fully rebuild severely damaged joints. It’s best seen as a promising option that may:
- Relieve pain
- Improve function
- Delay or avoid surgery
Results vary, so a thorough evaluation and honest discussion with your doctor are important for setting realistic expectations.
Conclusions and Considerations
Knee osteoarthritis is a challenging condition that affects both physical and mental well-being. While traditional treatments manage symptoms, stem cell therapy offers a new approach focused on healing and repair. South Korea stands out for its advanced technology, expert care, and supportive regulations, making it a top destination for this therapy. However, patients should be aware of the variable costs, lack of insurance coverage, and the need for realistic expectations.
