Autologous cartilage micrografting
Mytocel MSK. Prepared from the patient’s own cartilage, at the point of care.
Mytocel MSK® is an autologous cartilage micrografting procedure: the patient’s own auricular cartilage, mechanically disaggregated at the point of care into an injectable micrograft suspension.
- Tissue source
- Auricular cartilage, three 2.5 mm biopsies
- Processing
- Mechanical disaggregation, 80 µm
- Laboratory step
- None
- Session
- One outpatient visit, about 30 minutes
- Devices
- Rigeneracons® RS (Class IIa), N4SA (Class I)
- UK supply
- Actomed, exclusive
How it works
Four stages. One outpatient session.
Sampling, processing and administration in one outpatient session of around 30 minutes.

- 01
Prepare
Establish the sterile field and prepare the posterior auricular donor area under local anaesthetic, following the current professional protocol.
- 02
Sample
Take three 2.5 mm punch biopsies from the posterior auricular cartilage using the documented technique. No sutures are required.
- 03
Process
Disaggregate the samples mechanically in Rigeneracons® RS on the N4SA processing unit and collect the AMT® suspension through the calibrated 80 µm filter. No laboratory step.
- 04
Administer
Administer the suspension to the target joint by intra-articular injection within the same session, then complete aftercare and follow-up arrangements.

What the suspension contains
A suspension prepared from the patient’s own cartilage.
Characterisation studies describe a heterogeneous suspension of cartilage-derived cells (chondrocytes and progenitor cells), pericytes and extracellular-matrix components from the donor tissue.1
Mechanical disaggregation only: no laboratory expansion, no enzymatic digestion, no culture step.
Micrografts are collected through a calibrated 80 µm filter, the size range associated with viable progenitor-rich fractions in the characterisation work.1
Evidence
Three-year follow-up. Two prospective series. Every study linked in full.
Indications
Documented for early to moderate cartilage disease.
Manufacturer-documented indications: knee osteoarthritis grade I to III (Kellgren-Lawrence), focal cartilage injury or damage, chondromalacia patellae.
Not indicated in grade IV

The system
Two devices, one documented processing cycle.


Rigeneracons RS
Disaggregation device
Rigeneracons® RS: sterile, single-use Class IIa medical device, designed to mechanically disaggregate the auricular cartilage sample and collect the micrograft suspension through the calibrated 80 µm filter.
