Introduction: Medial open wedge high tibial osteotomy (MOWHTO) is one of the modalities to treat unicompartmental knee osteoarthritis (KO). Many studies have shown good outcomes of MOWHTO, but there are no published series of Malaysian patients. The aim of this study is to determine the outcome of MOWHTO in primary medial compartment KO in a university teaching hospital in Malaysia. Materials and methods: This is a retrospective study of patients who underwent MOWHTO in our Joint Reconstruction Unit between 2017 and 2022 with a minimum of 12 months follow-up. Results: Data from a total of 15 knees were reviewed. The mean age of patients was 41.8 years, and the mean BMI was 31.7. The mean Kellgren-Lawrence (KL) osteoarthritis grade was 2.87 (±0.52). The mean hip knee angle (HKA) preoperatively was 12.26° varus and post-operatively was 3.33° valgus. Mean correction of HKA was 13.59°. The results revealed an improvement in all patients, as observed from the significant mean difference between pre-operative (38.53) and post-operative (77.60) Knee Injury and Osteoarthritis Outcome (KOOS) (p-value<0.001) scores. Patients who were above 50 years old showed a significantly better improvement in KOOS score compared to those below 50 (p-value <0.05). There was no significant difference observed between BMI and KOOS score improvement (Fstat=0.580, p-value >0.05). Conclusion: MOWHTO is a good treatment option in medial compartment primary KO with varus deformity among Malaysian population. A larger sample size with a longer follow-up period is needed to draw a definitive conclusion

Introduction: The Malaysian Orthopaedic Journal (MOJ) (ISSN 1985-2533 / 2232-111X) is the official publication of the Malaysian Orthopaedic Association (MOA) and the ASEAN Orthopaedic Association (AOA). In May 2007, MOA published the first standalone issue of MOJ with the aim of disseminating new knowledge and providing updates in orthopaedics, trauma and musculoskeletal research. Since then, MOJ has grown significantly, achieving indexing in numerous databases and attaining a 2nd Quartile (Q2) rank in the Scopus database in 2022. This bibliometric analysis aims to explore the trends and distribution of articles published in MOJ. Materials and methods: Bibliometric data for MOJ was extracted from the SCOPUS database, covering the years from its indexing to 2022. Information such as authors, country, document type, author’s keywords, citations, and other parameters were extracted using the bibliometrix package in the R Studio software. The data were then presented in tables and illustrative graphs using the same software. Results: A total of 305 articles were retrieved from the Scopus database during the study period. Two-thirds of the articles were original articles and review articles. The highest number of citations received by an article is 56, and top ten articles in MOJ were authored by researchers from seven different countries, highlighting the journal’s diversity. Despite receiving submissions from various countries, there is minimal collaboration between authors of different countries. Keywords such as “covid-19” and “pandemic” dominate the authors’ keyword section due to the once-in-alife-time COVID-19 which during the study period, resulting in numerous publications related to this issue. Conclusion: This bibliometric analysis reviews all the articles indexed in the Scopus database and provides insight into the contributors’ information and the trends in orthopaedic research. By identifying the lack of collaboration between countries, it is hoped that this analysis can inspire more orthopaedic surgeons and researchers to collaborate and produce high-quality publications.

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.

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

We report on the medium term outcome of five patients (ten hips) who underwent one stage bilateral total hip arthroplasty. Both Harris Hip Scores and Oxford Hip Scores improved postoperatively as did range of motion. There was no radiographic evidence of loosening in any hip arthroplasty involved in this study, however one revision surgery was needed due to periprosthetic fracture. There were no increased medical complications. Based on our limited experience, we believe that one stage bilateral total hip
