1 Ass. Prof. Milan HANDL, MD, PhD Prague, Czech Republic

2 Ass. Prof. Milan HANDL, MD, PhD, Prague, CZ Ass. Prof. Milan HANDL, MD, PhD 1985 Graduate at Charles University Prague, Czech Republic 1988 I-st Attestation (orthopaedics) 1993 II-nd Attestation (orthopaedics) 2006 PhD 2008 Associate Professor Member of ESSKA Member of ESSKA - AFAS Member of ISAKOS

3 Orthopaedic Surgery Current employment: University Hospital Motol Orthopaedic Clinic V uvalu Prague 5, CZ deputy of chief of the clinic member of the teaching staff Private practice: Erpet Medical Centre Pstrossova Prague 1, CZ Ass. Prof. Milan HANDL, MD, PhD, Prague, CZ

4 Autologous Chondrocyte Implantation The special interest in: Ass. Prof. Milan HANDL, MD, PhD, Prague, CZ

5 Hyaline cartilage William Hunter (1718 – 1783) stated in 1743: … articular cartilage, when it is injured or possesses pathology, does not heal. Hunter W. Of the structure and diseases of articulating cartilage. Phil Trans 1743:42: Hyaline cartilage is an original congenital tissue, which when damaged is practically impossible to either fully restore or substitute with another tissue of similar quality. ACI – Autologous Chondrocyte Implantation belongs to most sofisticated and successful methods among the surgical orthopaedic procedures being utilized for the treatment. Ass. Prof. Milan HANDL, MD, PhD, Prague, CZ

6 How can we identify the cartilage derangement? We follow the symptoms in the joint as: pain swelling effusion instability limited range of motion The appearence of the symptoms can be slow at the very beginning Ass. Prof. Milan HANDL, MD, PhD, Prague, CZ

7 Follows This may cause that they cannot be early diagnosed and thus treated in an appropriate way, which can lead to secondary osteoarthritis (OA) Ass. Prof. Milan HANDL, MD, PhD, Prague, CZ

8 The main reasons for the cartilage defect are: recent joint cartilage injury posttraumatic follows severe chondropathies osteoarthritic cartilage degeneration osteochondriitis dissecans (OCD) postinflammatory etc. disorders Pathoethiology of cartilage defects ISAKOS - ESSKA Ass. Prof. Milan HANDL, MD, PhD, Prague, CZ

9 Arthroscopy for the evaluation of the cartilage surface derangements 1 st Gr: softenning + oedema 2 nd Gr: fragmentation of the surface 3 rd Gr: fibrillation, rupture 4 th Gr: erosion of the subchondral bone Outerbridge scale Ass. Prof. Milan HANDL, MD, PhD, Prague, CZ

10 10 What can we do??? Of course, it is necessary to scale the pathoethiology as well as to evaluate the cartilage defect properly. There are various kinds of surgical procedures as the option of the treatment… (from easy steps to the most sophisticated methods) Ass. Prof. Milan HANDL, MD, PhD, Prague, CZ

11 Surgical procedures shaving, debridement of the lesion arthroscopic drilling microfracturing autologous osteochondral grafting - mosaicplasty autologous chondrocyte implantation (ACI) Ass. Prof. Milan HANDL, MD, PhD, Prague, CZ

12 Autologous chondrocyte implantation in the form of a solid chondrograft (fixed by fibrin glue) as hyaline-like cartilage is considered as one of the most successful techniques developed to date used for reconstructing full-thickness chondral (cartilage) lesions. Ass. Prof. Milan HANDL, MD, PhD, Prague, CZ

13 Patients – Clinical Examination clinical pre-, intra- and postoperative evaluation: IKDC,Tegner, Lysholm, Mazur, Weber, AOFAS scores plain radiography: Anderson, Berndt and Harty scores MRI examination: pre- and postoperatively in 2m, and 1 to 10 yrs intervals Ass. Prof. Milan HANDL, MD, PhD, Prague, CZ

14 arthroscopic classification – Outerbridge score grade III and IV focal deep cartilage defects more than 4 cm² well contoured cartilage in the surroundings age 10 – 60 years Additional indications for a concommitant surgery: laesion of LCA – the joint instability unicompartmental OA – genu varum Indications for ACI ISAKOS - ESSKA Ass. Prof. Milan HANDL, MD, PhD, Prague, CZ

15 ACI surgery 1 st surgery step:a diagnostic arthroscopy utilizing by the instrumentation set ACI BH (Beznoska – Handl) checking the cartilage defect measuring of the defect´s size harvesting a rice-seed size piece of cartilage for culturing at the Tissue Bank (delivery within hours) Ass. Prof. Milan HANDL, MD, PhD, Prague, CZ

16 ACI surgery: 1-st surgery (arthroscopy) Ass. Prof. Milan HANDL, MD, PhD, Prague, CZ

17 The Tissue Bank - Material and Methods enzymatic isolation of chondrocytes in vitro culturing/ pimoculture/2-3 subcultures) nutrient medium at 37°C and 5% CO 2 atmosphere The quality control viability of cells – the proliferation test - inverted light microscopy fibrin glue suspension of chondrocytes ( million of cells per ml) forming a solid chondrograft soft, elastic and easy to handle transport to the operating room at room temperature up to 48 hours Growth Quality Control Primoculture of Chondrocytes Ass. Prof. Milan HANDL, MD, PhD, Prague, CZ
