What is the rotator cuff?
The rotator cuff is a group of four muscles and their tendons that surround the shoulder joint: supraspinatus, infraspinatus, teres minor, and subscapularis. They provide stability and rotation of the shoulder.
Rotator cuff tear is the most common cause of shoulder pain. Rotator cuff injuries are found in 20-30% of people over 60 years old and in 50% over 80 years old. Most often, the supraspinatus tendon is affected.
Types of tears:
- Partial (incomplete) — damage not through the full thickness of the tendon
- Complete (full-thickness) — tear through the entire thickness
- Massive — tear of 2+ tendons or larger than 5 cm
Causes:
- Degenerative — age-related wear (most common cause)
- Traumatic — fall on outstretched arm, sudden jerk
- Shoulder Impingement Syndrome — chronic tendon compression
- Sports-related — tennis, swimming, throwing
Facts about the rotator cuff
- ICD-10: M75.1
- Frequency: 20-30% of people over 60 years old
- Most common: supraspinatus tendon
- After surgical repair: re-tear rate 20-40%
- Surgeries: 300,000+/year (USA)
Symptoms of rotator cuff tear
Typical signs
- Shoulder pain, worsening at night
- Pain when raising arm to the side (60-120°)
- Weakness in arm abduction and rotation
- Clicking and popping with movement
- Limited active range of motion
Functional impairment
- Unable to raise arm above shoulder height
- Difficulty dressing, combing hair
- Pain when lying on affected shoulder
- Progressive muscle atrophy
- Painful arc during abduction
Complications without treatment
- Tear enlargement
- Fatty degeneration of muscles
- Tendon retraction
- Rotator cuff arthropathy
- Irreversible loss of function
Surgical repair vs MIBRAR®
| Criterion | Arthroscopic repair | Physical therapy | MIBRAR® |
|---|---|---|---|
| Principle | Suturing tendon to bone with anchors | Muscle strengthening, compensation | Tendon tissue regeneration with stem cells |
| Anesthesia | General anesthesia | None | Without anesthesia |
| Arm immobilization | 4-6 weeks in abduction sling | None | None — arm is free immediately |
| Rehabilitation | 4-6 months | Ongoing | 2-4 weeks |
| Re-tear rate | 20-40% of cases | — | Low risk — tissue is regenerated |
| Massive tears | Often irreparable | Compensation | Stem cells fill the defect |
How MIBRAR® restores the rotator cuff
Ultrasound and MRI diagnostics
The condition of all 4 tendons is assessed on MRI. Sono Control Arm™ allows real-time visualization of the tear, determining its size and degree of retraction.
Concentrate preparation
CGF — growth factors to stimulate tendon formation. Lipogems® — stem cells capable of differentiating into tenocytes (tendon cells).
Injection into the tear zone
Under Sono Control Arm™ guidance, concentrates are injected directly into the tendon tear zone, into the subacromial space, and into the damaged muscle tissue to prevent fatty degeneration.
Tendon regeneration
Stem cells form new tendon tissue in the tear zone, restoring cuff integrity. Growth factors reduce inflammation and stimulate collagen formation. Result — restoration of strength and range of motion within 2-4 months.
Why MIBRAR® is effective for rotator cuff tears
Surgical repair of the rotator cuff has a serious problem: re-tear occurs in 20-40% of cases, because degeneratively changed tendon heals poorly to bone. MIBRAR® solves this problem biologically.
Mechanism of action:
- Tendon formation — Lipogems® stem cells differentiate into tenocytes and synthesize type I collagen — the main structural protein of tendon
- Anti-fatty degeneration — stem cells injected into muscle prevent replacement of muscle tissue with fat (an irreversible process in prolonged tears)
- Anti-inflammatory effect — suppression of chronic inflammation that destroys the tendon
- Angiogenesis — improved blood supply to the tear zone to accelerate healing
MIBRAR® advantage: unlike surgical repair, which mechanically attaches the tendon to bone, MIBRAR® regenerates tissue — restores its structure and strength. This reduces the risk of re-tear.
MIBRAR® for rotator cuff tears
- Arm free immediately — no immobilization
- No general anesthesia — local anesthesia
- Both shoulders at once
- Massive tears — often irreparable surgically
- Prevention of fatty degeneration of muscles
