[Clinical results after articular cartilage injury revision surgeries]

Twenty-four patients underwent revision surgeries with osteochondral autotransplantation after failed primary articular cartilage restoration procedures in the Clinic of Orthopedics and Traumatology of Kaunas University of Medicine Hospital between 2000 and 2003. Primary microfracture procedure was performed for 22 patients and osteochondral autotransplantation for 2 patients. Patients were evaluated using International cartilage repair society (ICRS) and modified Hospital for Special Surgery (HSS) scales as well as with X-rays. Results of 22 (91.6%) revision osteochondral autotransplantations were excellent and good at the time of last follow-up; results of 2 (8.3%) operations were fair. Modified ICRS and HSS evaluation showed statistically significant improvement of clinical results following 13.2 months after revision osteochondral autotransplantation (p<0.005; p<0.001).
