Dezawa MuseCells® Therapy for Meniscus Damage, Avoiding Meniscectomy, and Preventing Arthritis
Your knee catches with every step.
The MRI confirmed what you feared: meniscus tear. Your orthopedic surgeon presents two grim options: remove the torn cartilage (meniscectomy)—guaranteeing arthritis within 10-20 years—or attempt surgical repair with 20-30% failure rate requiring four months non-weight-bearing recovery.
The torn meniscus won’t heal naturally, they explain. The inner portion lacks blood supply making regeneration impossible. You’re told the cartilage acts as “cushion” but removing it won’t cause problems immediately. They don’t emphasize that removing your meniscus—your knee’s shock absorber—dramatically accelerates arthritis, likely requiring total knee replacement in your 50s or 60s.
What if your meniscus could heal instead of being cut out?
At Muse Cell Procedure, we provide Dezawa MuseCells® therapy for meniscus tears—regenerative treatment supporting cartilage healing even in avascular zones, potentially avoiding meniscectomy that guarantees future arthritis.
For meniscus tear patients facing removal surgery or uncertain repair outcomes, regenerative medicine offers cartilage healing and joint preservation.

Understanding Meniscus Tears
The Knee’s Shock Absorber
The American Academy of Orthopaedic Surgeons reports that about 850,000 meniscus surgeries are performed each year in the United States—making it one of the most common orthopedic procedures.
What is the meniscus?
Each knee contains two C‑shaped fibrocartilaginous structures—the medial (inner) and lateral (outer) menisci—sitting between the femur and tibia. These menisci distribute weight, absorb shock (reducing forces on articular cartilage by more than 50 %), and stabilize the joint. Removing even a small portion dramatically increases contact pressures, accelerating arthritis.
Meniscus anatomy & blood supply
| Zone | Vascularity | Healing potential |
|---|---|---|
| Red zone (outer 1/3) | Vascular | Can heal with repair |
| Red‑white zone (middle 1/3) | Some blood supply, variable healing | |
| White zone (inner 2/3) | Avascular | Historically considered non‑healing |
Most tears occur in the white or red‑white zones where natural healing capacity is limited.
Types of meniscus tears
- Degenerative: horizontal cleavage, complex/frayed, chronic wear‑related (common > 40 yrs)
- Traumatic: vertical longitudinal, bucket‑handle, radial, root tears (often sports‑related or acute injury)
Common causes
| Age group | Typical trigger |
|---|---|
| Younger patients | Twisting with foot planted, sudden pivoting, deep squatting, contact sports (football, basketball, soccer); often concurrent ACL tear |
| Older patients | Age‑related cartilage weakening, cumulative microtrauma, simple motions (squatting, standing from a chair) – part of osteoarthritis development |
Symptoms
- Mechanical: catching/locking, knee giving way, inability to fully straighten, popping or clicking
- Pain & swelling: joint‑line pain, swelling within 24 h, worsened by twisting/squatting, difficulty bearing weight, night pain
- Functional limitations: reduced range of motion, trouble squatting/kneeling, stairs, running/jumping, inability to play sports
Serious complications
- Progressive arthritis (especially after meniscectomy)
- Persistent pain and dysfunction
- Recurrent tears after repair
- Need for eventual total knee replacement
- Chronic instability, reduced quality of life
Meniscus tears severely impair knee function and accelerate arthritis if removed.
Why Menisci Don’t Heal Naturally
| Barrier | Explanation |
|---|---|
| Avascular white zone | Inner two‑thirds lack blood vessels—no delivery of healing cells, nutrients, or growth factors. |
| Mechanical stress | Constant weight bearing and motion create a hostile environment for stable repair. |
| Poor cellular activity | Sparse, low‑metabolic cells in the white zone are insufficient for significant tissue regeneration. |
| Complex tear patterns | Horizontal, complex, and degenerative tears resist healing due to poor tissue quality and geometry. |
These factors render most meniscus tears—especially those in the white zone—essentially non‑healing without intervention.
💡 Quick Fact: Long‑term studies show patients who undergo meniscectomy have a 14‑fold higher risk of developing knee osteoarthritis compared with those whose meniscus remains intact, underscoring the importance of preserving this shock absorber.
Conventional Treatment Limitations
Removal Guarantees Arthritis
Conservative care
- Rest, ice, activity modification
- Physical therapy for strengthening
- NSAIDs for pain control
- Effective only for small, stable tears; most tears do not resolve without intervention
Arthroscopic partial meniscectomy (removal)
- Most common procedure (~600 k+ annually)
- Surgeon removes the torn segment
- Quick recovery (2–4 weeks), immediate symptom relief
- Problem: Removal eliminates shock‑absorbing cartilage, guaranteeing arthritis over time; studies show arthritis can develop in 10–20 years and often leads to knee replacement. Younger patients face decades of degeneration.
Meniscus repair (suture)
- Attempts to preserve the meniscus
- Only works for tears in the vascular red zone
- Requires 4–6 months of protected weight bearing
- 20–30 % failure rate, sometimes requiring re‑operation
- Many tears are not repairable due to location or pattern; complex rehab needed
Meniscal transplant
- Donor meniscus for young patients after total meniscectomy
- Complex, expensive, limited availability, variable long‑term outcomes, still not the patient’s own tissue
The dilemma: Removing the meniscus guarantees arthritis, while repair has a high failure rate and is often deemed “irreparable” for white‑zone tears. Neither option truly meets the goal of restoring native knee function.
How Dezawa MuseCells® Heal Meniscus Tears
Regenerating Avascular Cartilage
1. Support Healing in White Zone
MuseCells provide regenerative capacity to the avascular white zone where natural healing is impossible.
- Deliver stem cells directly into the poorly vascularized tissue
- Supply growth factors that compensate for lack of blood flow
- Stimulate chondrocyte activity even in low‑cell‑density areas
- Promote fibrocartilage formation, enabling repair previously unattainable
Result: A healed meniscus that obviates removal.
2. Promote Tissue Regeneration
Stem cells can differentiate into meniscal fibrochondrocytes and support matrix production.
- Differentiate into the specialized cells that make meniscal tissue
- Stimulate collagen (primarily type I) synthesis
- Increase proteoglycan production for a resilient extracellular matrix
- Restore the structural integrity of the meniscus
Result: Regenerated, functional meniscal tissue capable of bearing load.
3. Reduce Inflammation
Acute tears trigger significant joint inflammation that hinders healing.
- Lower inflammatory cytokines (IL‑1, TNF‑α, IL‑6)
- Decrease joint swelling and synovial irritation
- Create a favorable environment for tissue repair
- Alleviate pain associated with inflammation
Result: Enhanced healing conditions and immediate symptom relief.
4. Enhance Vascularization
Angiogenesis into poorly vascularized zones improves nutrient delivery and cellular metabolism.
- Stimulate new blood vessel formation in the red‑white transition
- Improve oxygen and nutrient supply to regenerating cells
- Support cellular metabolism, accelerating repair
- Facilitate integration of newly formed tissue with existing meniscus
Result: Better‑nourished tissue that heals more effectively.
5. Prevent Arthritis Development
By preserving and restoring the meniscus, joint health is protected long term.
- Maintain the knee’s natural shock‑absorbing function
- Preserve normal contact pressures on articular cartilage
- Protect adjacent structures from accelerated wear
- Reduce the risk of early osteoarthritis
Result: A knee that remains healthy for decades.
6. Restore Knee Function
As the meniscus heals, mechanical symptoms resolve and normal biomechanics resume.
- Eliminate catching, locking, and giving‑way sensations
- Restore full range of motion
- Allow pain‑free weight bearing
- Enable return to sports, daily activities, and high‑impact movements
Result: A fully functional knee without surgical intervention.
