Autologous chondrocyte implantation (ACI) is a widely accepted procedure for the treatment of large, fullthickness
chondral defects involving various joints, but its use in developing countries is limited because of high
cost and failure rates due to limited resources and support systems. Five patients (age <45 years) with focal
cartilage defects received ACI at University of Malaya from 2006 to 2007 and followed up for 36 months. The
average presubjective Knee Evaluation Forms (IKDC) improved from 38.44±6.29 to 25.6±8.04 postoperatively,
the Oxford Knee Score (OKS) went from 25.6±8.04 to 13.96±1.63 and the American Knee Society Score (AKSS)
improved from 80±14.33 to 92.96±5.82 post-operatively. Thus improvements were seen in the IKDC and
AKSS score but not in the OKS. Magnetic resonance images showed the presence of cartilage tissue filling in
the lateral and medial patellar facet and medial femoral condyle in three patients. Failures were seen in two
patients, both with patellar defects and over the age of 36 years. Treatment with autologous chondrocyte
implantation for focal cartilage defect in lateral and medial patellar facet and medial femoral condyle showed
early improvement which was maintained at 3 yrs follow-up. ACI provided satisfactory outcome in focal cartilage
defects involving the femoral condyle.
