Posology 
 
The amount of MACI administered is dependent upon the size (surface in cm2) of the cartilage defect. 
The implantation matrix is trimmed by the treating surgeon to the size and shape of the defect, to ensure 
the damaged area is completely covered, and implanted cell-side down. The administered dose 
corresponds to 500,000 to 1,000,000 autologous cells/cm2 of implantation matrix. 
 
Special populations 
 
Older people (over 65 years of age) 
 
The use of MACI in this age group has not been studied. The use of MACI in elderly with generalised 
degeneration of the cartilage or osteoarthritis is not recommended.  
 
Paediatric population 
 
The safety and efficacy of MACI in children less than 18 years of age have not been established.  
No data are available. 
 
Method of administration 
  
For implantation. 
 
The defect bed should be debrided only down to the subchondral plate and not through it. Bleeding 
through the subchondral plate should be avoided, but if it occurs, it must be controlled. Epinephrine or 
fibrin sealant (see section 4.5), applied sparingly directly to bleeding points, is a suitable haemostatic 
agent. 
 
Implantation of MACI is performed using sterile surgical techniques and requires both the preparation of 
the defect bed and the application of fibrin sealant to the base and rim of the defect in order to secure the 
implant. At the surgeon’s discretion, a few interrupted absorbable sutures may also be used to provide 
extra security. 
The implantation should be followed by an appropriate rehabilitation schedule (see section 4.4). 
 
For information on preparation and handling of MACI, please refer to section 6.6.  
 
4.3 Contraindications 
 

• Hypersensitivity to any of the excipients listed in section 6.1, or porcine products, or any residual 
component carried over from manufacture of MACI, including bovine serum, and gentamicin. 

 
• Severe osteoarthritis of the knee. 

 
• Inflammatory arthritis, inflammatory joint disease, or uncorrected congenital blood coagulation 

disorders.

4.4 Special warnings and precautions for use 
 
General 
 
MACI is an autologous implant and must only be administered to the patient for whom it was 
manufactured. Implantation of MACI is to be performed during arthrotomy under sterile conditions. 
There is limited experience with delivery of MACI to the knee via arthroscopy, however, arthroscopic 
techniques may be used to apply MACI at the discretion of the treating physician. 
 
Precautions for use 
 
Patients with local inflammations or active infections in the bone, joint, and surrounding soft tissue 
should be temporarily deferred until documented recovery.  
 
In the pivotal study of MACI, patients were excluded if they had a history of osteoarthritis 
(Kellgren-Lawrence Grade 3 or 4) in the target knee, or concomitant inflammatory disease. 
 
To create a favourable environment for healing, concomitant pathologies must be addressed prior to or 
concurrent with implantation of MACI. These include: 
 

• Meniscal pathology: unstable or torn meniscus requires repair, replacement, or partial 
meniscectomy.  MACI is not recommended in patients with a total menisectomy unless the 
meniscal deficiency can be addressed with a staged or concurrent meniscal graft. 

 
• Cruciate ligament instability: the joint should not possess excessive laxity. Both anterior and 

posterior cruciate ligaments should be stable or undergo reconstruction to reduce shearing forces 
and rotation stresses across the joint.  

 
• Malalignment: the tibio-femoral joint should be properly aligned. Abnormal varus or valgus 

loading of the tibio-femoral joint may jeopardise the implant and should be addressed with a 
corrective osteotomy or similar procedure. When treating trochlear and patellar defects, 
abnormal patellar tracking must be corrected, prior to or concurrent with MACI implantation.  

 
Post-operative haemarthrosis occurs mainly in patients with a predisposition to haemorrhage or poor 
surgical haemorrhage control. The patient’s haemostatic functions should be screened prior to surgery. 
Thromboprophylaxis should be administered according to local guidelines. 
 
Local treatment guidelines regarding the use of antibiotic prophylaxis around orthopaedic surgery should 
be followed. 
 
Due to limited experience, the use of MACI in joints other than the knee is not recommended. 
 
MACI is shipped following a validated rapid microbial sterility assay to determine absence of microbial 
growth.  Final sterility test results are not available at the time of shipping. If positive sterility results are 
obtained, the treating physician will be contacted to discuss either cancellation of the implantation or a 
plan of action based on the patient-specific circumstances and risk assessment.

Rehabilitation 
 
Controlled physiotherapy, including early mobilisation, range-of-motion exercises, and partial weight-
bearing is recommended as soon as possible to promote graft maturation and to reduce the risk of post-
operative thromboembolic events and joint stiffness. Following implantation, the patient should follow 
an appropriately controlled, phased rehabilitation  programme as recommended by the treating physician 
based on the MACI Rehabilitation Manual. This should include specified or staged physical activity in 
order to minimise the likelihood of arthrofibrosis and graduated partial weight-bearing. Return to 
sporting activity should be personalised in consultation with healthcare professionals. 
 
Cases in which MACI cannot be supplied 
 
In some cases, it may occur that source chondrocytes of the patient are not expandable or that the release 
criteria (see section 6.6) are not met due to poor biopsy quality, patient characteristics, or manufacturing 
failure.  Therefore, it may occur that MACI cannot be delivered.   
 
4.5 Interaction with other medicinal products and other forms of interaction 
 
Fibrin sealants containing formaldehyde must not be used with MACI, since formaldehyde is cytotoxic to 
the chondrocytes. 
 
While oral use of pain medication is recommended for post-surgical pain relief, intra-articular 
administration of analgesics is not recommended as studies have shown adverse effects on articular 
cartilage and chondrocytes with exposure. 
 
4.6 Fertility, pregnancy and lactation 
 
Pregnancy 
 
Limited clinical data on exposed pregnancies are available. Conventional reproductive and 
developmental toxicity studies are not considered relevant, given the nature and the intended clinical use 
of the medicinal product. Given the local nature of the medicinal product, adverse reactions of MACI on 
pregnancy are not anticipated. However as MACI will be implanted using invasive surgical techniques, it 
is not recommended during pregnancy. 
 
Breast-feeding  
 
There are no data on the use of MACI during breast-feeding. Given the local nature of the product, 
adverse reactions of MACI on the nursing infant are not anticipated. However as MACI will be 
implanted using invasive surgical techniques, a decision must be made whether to discontinue breast-
feeding taking into account the benefits of treatment for the woman and the risk to the infant. 
 
Fertility 
 
There are no data on possible effects of MACI treatment on fertility.

4.7 Effects on ability to drive and use machines 
 
Due to the surgical nature of the underlying procedure, implantation with MACI has a major influence on 
the ability to drive and use machines. During the rehabilitation period that follows MACI treatment 
patients should refer to their treating physician and follow their advice. 
 
4.8 Undesirable effects 
 
Summary of the safety profile 
 
Based on the exposure of more than 6,000 patients  to MACI treatment in the knee, complications may 
be related to the arthrotomy procedure, general complications related to surgical intervention, other knee 
pathology (such as ligamentous or meniscal pathology), or the biopsy procurement. Complications 
related to knee surgery in general may also include deep vein thrombosis and pulmonary embolism.  
Other complications have been identified as causally related to MACI. The following important risks 
have been identified related to either MACI or peri-operative complications:  
 
Related to MACI: 
 

• Symptomatic graft hypertrophy 
• Graft delamination (complete or partial, possibly leading to loose bodies in the joint or graft 

failure) 
 
Peri-operative complications related to surgical intervention of the knee: 
 

• Haemarthrosis 
• Arthrofibrosis 
• Localised surgical site inflammation 
• Localised surgical site infection 
• Thromboembolic events 

 
Tabulated list of adverse reactions 
 
Adverse reactions are listed by System Organ Class and frequency. Frequencies are defined according to 
the following convention: very common (≥ 1/10); common (≥ 1/100 to < 1/10); uncommon (≥ 1/1,000 to

Description of selected adverse reactions 
 
Graft delamination: 
 
Graft delamination refers to a loosening, either partial or total, of the graft from the subchondral bone and 
from the surrounding cartilage. A total graft delamination is a serious complication and the patient may 
experience locking, pain, and swelling after an acute distortion of the knee. 
 
Risk factors for graft delamination can include but are not limited to poor patient selection, poor 
adherence to recommended surgical technique, failure to address concomitant pathologies, poor 
compliance with the rehabilitation protocol or post-operative trauma to the knee. 
 
Graft hypertrophy: 
 
Symptomatic graft hypertrophy is acomplication that may occur with MACI.  
 
Symptoms may include catching or pain. There are no known risk groups or specific risk factors for graft 
hypertrophy in patients treated with MACI. Patients may require debridement of the hypertrophic tissue 
via arthroscopy.

5. PHARMACOLOGICAL PROPERTIES 
 
5.1 Pharmacodynamic properties 
 
Pharmacotherapeutic group: Other Medicines for Disorders of the Musculo-Skeletal system, ATC code: 
M09AX02  
 
Clinical pharmacology studies have not been conducted on MACI.  Current clinical and nonclinical 
evidence suggests that delivery of autologous chondrocytes on the collagen membrane promotes 
proliferation and re-differentiation of seeded cells, and may result in synthesis of hyaline-like cartilage 
repair tissue. 
 
MACI has been investigated in a parallel, randomised, open-label trial in 144 patients with Outerbridge 
Grade III or IV focal cartilage defects of the knee of 3-20 cm2 (median 4 cm2).  Seventy-two patients 
received MACI, and 72 were treated with microfracture. The median age of patients was 34 to 35 years 
(age range: 18 to 54), and the mean body mass index was 26. The majority of patients had undergone at 
least 1 prior orthopaedic knee surgery. MACI was superior compared to microfracture regarding the 
improvement of pain and function according to the KOOS scale (Knee Injury and Osteoarthritis Outcome 
Score). See responder rates in Table 1 below.  
 
Four patients were treatment failures in the microfracture treatment arm, versus one in the MACI 
treatment arm. There were no significant differences observed in the structural markers of cartilage repair 
between both treatments, as assessed by International Cartilage Repair Society (ICRS) II overall 
assessment histology scores of biopsies, and MRI defect fill scores.

* KOOS Response Rate: Responder is defined as an improvement of the Knee Injury and Osteoarthritis 
Outcome Score from baseline of minimal 10 points of a scale of 100. 
 
Paediatric population 
 
The European Medicines Agency has deferred the obligation to submit the results of studies with MACI 
in paediatric patients from the closure of the femoral epiphyseal growth plate to less than 18 years of age. 
See section 4.2 for information on paediatric use.  
 
5.2 Pharmacokinetic properties 
 
Typical clinical pharmacokinetic (ADME) studies have not been performed on MACI. The 
pharmacokinetic behaviour of MACI is related to the resorption of the collagen membrane, a proteolytic 
process performed by cells in the vicinity of the defects. The membrane is resorbed over the months 
following implantation.  
 
5.3 Preclinical safety data 
 
Non-clinical data based on implantation of MACI in rabbits and horses did not reveal any special hazard 
for humans. 
 
Non-clinical in vitro investigations have shown that the collagen membrane is non-cytotoxic, non-
mutagenic, non-reactive (short- and long-term implantation), non-sensitising, a negligible irritant, and 
non-toxic (acute systemic).  
 
A rabbit study demonstrated that at 3 months post-implantation, minimal numbers of inflammatory cells 
were present in the vicinity of the defect, with variable chondrogenesis.  In a horse study, signs of a 
minor inflammatory response, characterised by a slight increase in synovial fluid volume and a mild 
lymphoid accumulation in the synovium, were observed at 3 months. By 6 months, these signals had 
subsided, resulting in a normal synovial appearance. There were no indications of gross inflammatory 
reaction.

6.2 Incompatibilities 
 
In the absence of compatibility studies, this medicinal product must not be mixed with other medicinal 
products. 
 
6.3 Shelf life 
 
6 days. 
 
6.4 Special precautions for storage 
 
Keep MACI in the outer carton until ready to use. Do not refrigerate or freeze. Store shipping box in an 
area below 37°C.  
 
6.5 Nature and contents of container and special requirement for use, administration or 

implantation 
 
MACI is shipped in custom-designed, sterile, sealed, clear polystyrene dishes.  
 
Each dish contains 1 implantation matrix, held in place by a green polycarbonate x-ring and closed with a 
green polycarbonate cover for shipment.  
 
Each dish is sealed in a gamma-irradiated clear plastic bag. 
 
MACI is supplied in 1 to 2 dishes, which are placed into a 95kPa pouch (outer bag) with absorbent 
material for transport.  
 
This package is enclosed in an outer carton insulated with ambient gel packs. 
 
6.6 Special precautions for disposal and other handling 
 
During the first procedure, a sample of healthy cartilage tissue (a biopsy) will be taken from the affected 
joint by an arthrotomy or arthroscopy.  
 
The biopsy will be sent to the cell processing facility. At the cell processing facility, the cartilage cells 
will be grown aseptically in culture to expand the number of cells and placed onto a sterile CE marked 
porcine derived type I/III collagen membrane, to make MACI. MACI will be released following M

11 

 

successful results from assays which assess chondrocyte viability, identity, potency, minimum cell 
number, endotoxin, pre-release sterility, and mycoplasma. 
 
MACI will be sent to the treatment facility. At this time, MACI will be implanted into the cartilage 
defect in the affected joint via a second procedure. The MACI implant will be secured in place using a 
fibrin sealant.  
 
The timing between the removal of the biopsy and MACI implantation can vary depending on logistical 
factors in addition to the quality and number of cells obtained from the biopsy. The minimum amount of 
time is 6 weeks; however, cells can also be cryopreserved and held in storage for up to 24 months until a 
surgical date is established. 
 
The surgeon will organise the date for MACI implantation in consultation with the Marketing 
Authorisation Holder (MAH) or its local representative. In rare cases the MAH will not be able to 
produce a MACI implant from the available cells. If this occurs, the surgeon will advise the patient on 
the best course of action. 
 
Any unused medicinal product or waste material should be disposed of as surgical waste in accordance 
with local requirements. 
 
Please consult the Surgical Technique Manual for further information.

1. What MACI is and what it is used for 
 
MACI is used in adults to repair cartilage defects in your knee joint. Cartilage is a tissue that is present in 
every joint in the body; it protects the ends of bones and allows joints to function smoothly. 
 
MACI is an implant consisting of a porcine derived (derived from pigs) collagen membrane which 
contains your own cartilage cells (called autologous chondrocytes) and is implanted into your knee. 
“Autologous” means that your own cells are used which have been taken from your knee (through a 
biopsy) and grown outside the body.  
 
 
2. What you need to know before you use MACI 
 
Do NOT use MACI if you: 
 

• are allergic to any of the ingredients of MACI (listed in section 6), or porcine products (derived 
from pigs), bovine serum (a protein derived from cows) or gentamicin (an antibiotic)  

• have severe osteoarthritis of the knee (disease of the joints with pain and swelling) 
• currently suffer from inflammatory arthritis or inflammatory joint disease of the knee 
• have a known, uncorrected bleeding disorder 
• have a growth plate of the knee that is not fully closed.

Warnings and precautions  
 
Your MACI implant has been manufactured specifically for you and cannot be administered to any other 
patient. 
 
MACI should be implanted in a reasonably healthy joint. This means that other problems in the joint 
should be corrected before or during MACI implantation. 
 
If you have a sudden occurrence or recent history of bone or joint infections, your MACI treatment 
should be temporarily delayed until your doctor considers that you have recovered. 
 
Tell your doctor or surgeon if you know you have a predisposition for bleeding or poor bleeding control 
following surgical procedures.  
 
You may also be given antibiotics or pain-killers to help reduce some of the side effects.  
 
It is important that you closely follow the rehabilitation programme recommended by your doctor. Please 
discuss with your doctor or physical therapist when to re-start specific physical activities. 
 
Your surgeon will give you more information on any special considerations for your particular case. 
 
Other situations in which MACI cannot be given 
 
Even if the surgeon has already taken a small sample of cartilage cells (a biopsy) needed to produce the 
MACI implant, it is possible that you will not be eligible for treatment with MACI.   
This is the case if: 
 

• the biopsy is of insufficient quality to produce MACI for you 
• the cells cannot be grown in the laboratory  
• the increased cells do not meet all the quality requirements.  

 
In such situations, your surgeon will be informed and might have to select an alternative treatment for 
you. 
 
Older people 
 
The use of MACI is not recommended in patients over 65 years of age who have generalised 
degeneration of the cartilage or osteoarthritis (disease of the joints with pain and swelling). 
 
Children and adolescents 
 
The use of MACI is not recommended in children and adolescents below 18 years. 
 
Other medicines and MACI 
 
Please tell your doctor, surgeon or physical therapist if you are taking or have recently taken any other 
medicines, including medicines obtained without a prescription. 
 
Ask your doctor or surgeon for more information as to which pain medicine you can safely use.  
Administration of pain relievers into the joint is not recommended. M

Pregnancy and breast-feeding 
 
The safe use of MACI has not been demonstrated during pregnancy or breast-feeding. 
MACI is not recommended for pregnant women. 
Please inform your doctor or surgeon if you are pregnant or think you may be pregnant. 
Talk to your doctor or surgeon if you are breast-feeding. Depending on your particular situation, your 
doctor or surgeon will advise you on whether or not to continue breast-feeding. 
 
Driving and using machines 
 
The surgical procedure will have a major impact on your ability to drive and use machines.  
Driving and using machines may be limited during the rehabilitation period, and the advice of your 
doctor, surgeon or physical therapist should be strictly followed during this period. 
 
 
3. How to use MACI 
 
MACI must only be implanted by surgeons who have been specifically trained for this kind of surgery.  
 
A small amount of blood (4 ml) will be taken by a qualified person for testing.  
 
You will need to have two surgical procedures to receive this treatment: 
 

1. During the first procedure, a sample of healthy cartilage cells (a biopsy) will be taken from your 
joint by arthrotomy or arthroscopy. Your surgeon will explain what arthrotomy and athroscopy 
procedures are. 

 
The biopsy will be sent to the cell processing facility. At the cell processing facility, your 
cartilage cells will be grown aseptically (free from germs) in culture, to increase the number of 
cells, and placed onto a sterile collagen membrane to make MACI. 

 
2. The final MACI implant will be sent back to your surgeon. The MACI will then be implanted 

into the cartilage defect in your joint by a second procedure. MACI will be secured in place 
using a fibrin sealant. A fibrin sealant is a type of glue that is made from human blood-clotting 
proteins. 

 
The length of time between your biopsy and the implantation of MACI can vary depending on the 
procedure date and the quality and number of cells in the biopsy. On average this will be 6 weeks, 
however, cells can also be frozen and held in storage for up to 2 years until a convenient date for surgery 
is agreed between you and your surgeon. Your surgeon will organise the date for implantation. 
In rare cases the cell processing facility will not be able to produce MACI from your cells. If this 
happens, your surgeon will advise you on the best course of action. 
 
Your doctor will discuss with you the specific rehabilitation programme that follows your surgery.

4. Possible side effects 
 
Like all medicines, MACI can cause side effects, although not everybody gets them.  
 
When you receive MACI, you may experience side effects soon after the implantation. These effects will 
gradually reduce over time. 
 
Your doctor may give you other medicines to help reduce any side effects (see section 2 “Warnings 
and precautions”). 
 
Complications may be related to MACI or to the surgical procedure, or both. Complications related to 
knee surgery in general may include deep vein thrombosis (blood clotting in a deep vein) and pulmonary 
embolism (blood clotting in the lung due to blockage of a lung artery).  If you notice any of the 
following, please contact your doctor immediately, since these may be symptoms of blood clotting: 

• difficulty breathing, chest pain and palpitations 
• leg swelling, leg pain and redness 

 
Risks involved with implantation of MACI:  
 
The following uncommon side effect may affect up to 1 in 100 people: 
 

• too much cartilage growth. 
• the graft may detach completely or partially from the defect in the joint. You may require 

more surgery to correct this 
 
Risks involved with arthrotomy or arthroscopy or MACI  
 
All surgical procedures carry a certain risk. Your surgeon can explain these to you.   
The following rare side effects may affect up to 1 in 1,000 people: 
 

• infection 
• inflammation 
• post-operative pain 
• bleeding in the joint 
• joint stiffness/numbness 
• swelling of the joint 
• fever  

 
Your surgeon or anaesthetist will explain to you the risks involved with the procedures as well as any 
additional specific risks that are applicable to you because of your medical history and current medical 
status. 
 
Reporting of side effects 
 
If you get any side effects, talk to your doctor, surgeon or physical therapist. This includes any possible 
side effects not listed in this leaflet. You can also report side effects directly via the national reporting 
system listed in Appendix V. By reporting side effects you can help provide more information on the 
safety of this medicine.

The biopsy will be sent to the cell processing facility. At the cell processing facility, the cartilage cells 
will be grown aseptically in culture to expand the number of cells and placed onto a sterile collagen 
membrane, to make MACI. 
 
MACI will be sent back to the surgeon. At this time MACI will be implanted into the cartilage defect in 
the affected joint via a second procedure. The MACI implant will be secured in place using a fibrin 
sealant.  
 
The timing between the removal of the biopsy and the implantation of the MACI implant can vary 
depending on logistics and the quality and number of cells in the biopsy. On average this will be 6 weeks, 
however, cells can also be cryopreserved and held in storage for up to 2 years until a convenient date for 
surgery is agreed between the patient and surgeon. 
 
The surgeon will organise the date for implantation in consultation with the Marketing Authorisation 
Holder (MAH) or its local representative. In rare cases the MAH will not be able to produce a MACI 
implant from the available cells. If this occurs the surgeon will advise the patient on the best course of 
action. 
 
Please consult the Surgical Technique Manual for further information.

{'Title': '3. how to use maci', 'Section_Content': 'maci must only be implanted by surgeons who have been specifically trained for this kind of surgery. a small amount of blood (4 ml) will be taken by a qualified person for testing. you will need to have two surgical procedures to receive this treatment: 1. during the first procedure, a sample of healthy cartilage cells (a biopsy) will be taken from your joint by arthrotomy or arthroscopy. your surgeon will explain what arthrotomy and athroscopy procedures are. the biopsy will be sent to the cell processing facility. at the cell processing facility, your cartilage cells will be grown aseptically (free from germs) in culture, to increase the number of cells, and placed onto a sterile collagen membrane to make maci. 2. the final maci implant will be sent back to your surgeon. the maci will then be implanted into the cartilage defect in your joint by a second procedure. maci will be secured in place using a fibrin sealant. a fibrin sealant is a type of glue that is made from human blood-clotting proteins. the length of time between your biopsy and the implantation of maci can vary depending on the procedure date and the quality and number of cells in the biopsy. on average this will be 6 weeks, however, cells can also be frozen and held in storage for up to 2 years until a convenient date for surgery is agreed between you and your surgeon. your surgeon will organise the date for implantation. in rare cases the cell processing facility will not be able to produce maci from your cells. if this happens, your surgeon will advise you on the best course of action. your doctor will discuss with you the specific rehabilitation programme that follows your surgery.', 'Entity_Recognition': [{'Text': 'maci', 'Type':
