Abstract
The distal femurs of 100 subjects (50 men, 50 women) from the Malay population aged between 19 and 38 years were scanned to measure the anterior-posterior (AP) and medial-lateral (ML) width. The mean AP values were 64.02 ± 3.38 mm and 57.33 ± 3.26 mm for men and women, respectively, and the mean ML values were 74.91 ± 3.52 mm and 64.53 ± 3.07 mm. We compared our data to that published previously for the Chinese and Indian populations. It was found that the Malay population had smaller distal femur than that of the Chinese but was larger than that of the Indian population (P < 0.05). In conclusion, although it is well established that Asians have a smaller distal femur size than that of the Western population, the variations in different Asian ethnicities may need to be considered when designing the appropriate knee implant.
Highlights
Joint replacement involving the distal femur requires the use of highly complex surgical techniques, as this would involve the accurate placement of well-fitted implants and adequate balancing of the surrounding soft tissues [1, 2]
There were, cases where total knee replacements were performed on the young age group of 45 and below for treatment of rheumatoid arthritis, juvenile rheumatoid arthritis, and osteoarthritis [11, 12]
The aim of the current study is to determine the anthropometric measures of the distal femur amongst the young adult Malay population in Malaysia, measured using three-dimensional models reconstructed from computer tomographic (CT) images datasets
Summary
Joint replacement involving the distal femur requires the use of highly complex surgical techniques, as this would involve the accurate placement of well-fitted implants and adequate balancing of the surrounding soft tissues [1, 2]. The use of appropriate component size is crucial to produce long-term success following total knee arthroplasty (TKA) [6,7,8,9,10]. Most arthroplasty of the knee are normally performed on the diseased knees to return the knee to its normal physiological function. Most of these pathological diseases of the joint affected people at the age of 45 and above. There were, cases where total knee replacements were performed on the young age group of 45 and below for treatment of rheumatoid arthritis, juvenile rheumatoid arthritis, and osteoarthritis [11, 12]. Follow-up studies reported cases of posttraumatic arthritis, avascular necrosis, hemochromatosis, lupus, dislocation, sepsis, unstable components, and osteolysis for this age group
