We report the outcome of 32 patients who underwent total hip replacement (THR) augmented with morsellized fresh frozen femoral head allografts and acetabular reconstruction cages. Nine patients underwent primary THR and 23 patients underwent revision THR. Follow up ranged from two to 9 years. Two most common indications for the procedures as reported in literature were rheumatoid arthritis and aseptic loosening of the hip. All but one patient achieved good outcome with radiographs showing full incorporatio

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.

Introduction: Early identification of patients at risk for severe multisystem inflammatory syndrome in children (MIS-C) is essential for favourable clinical outcomes. This study aims to identify the clinical characteristics, factors and outcomes associated with severe MIS-C. Materials and methods: In this retrospective cohort study involving 14 major hospitals in Malaysia, children <15 years who met the United States Centres for Disease Control and Prevention case definition for MIS-C were included. Severe MIS-C was defined as children who required inotropic support, ventilatory support (invasive or non-invasive ventilation), or left ventricular ejection fraction of <55%. The factors investigated for severe MIS-C were demographic characteristics, the presence of comorbidities, clinical characteristics, and laboratory measures. Multivariable logistic regression was used to compute the adjusted odds ratio (aORs) of factors associated with severe MIS-C. Results: Among the 155 patients, 91 (58.7%) presented with severe MIS-C. Severe MIS-C was more likely in patients aged ≥5 years old (aOR 2.13, 95% confidence interval [CI] 1.08-4.21), with dehydration (aOR 3.80, 95% CI 1.53-9.45), lethargy (aOR 2.02, 95% CI 0.97-4.18), tachycardia (aOR 8.33, 95% CI 3.27-21.22), albumin <30g/L (aOR 3.36, 95% CI 1.58-7.13), creatine kinase >200U/L (aOR 3.68, 95% CI 1.57-8.64), D-dimer >3.0µg/mL (aOR 2.11, 95% CI 1.08-4.13), ferritin >500ng/mL (aOR 3.77, 95% CI 1.88-7.55), prothrombin time >12.7 seconds (aOR 3.22, 95% CI 1.61-6.43), and urea >6mmol/L (aOR 5.09, 95% CI 2.04-12.71). Conclusion: Identification of these associated factors of severity in MIS-C could aid in early recognition and prompt escalation of care, leading to better outcomes.
