“…The female-to-male ratio is much higher in Asian studies than the ratio observed in Western series [18]. Second, the average anatomical profile of the female knee is smaller than that of male knee [11], but most total knee systems are unisex in design. If a similar thickness is used for each bone cut in men and women, a distal femoral bone cut may end up involving the popliteus-femoral attachment in smaller female knees.…”

“…A previous analysis of patient demographic data [10] revealed that a greater number of females than males and the anatomical profile of the distal femur [11] indicated that the average medio-lateral and antero-posterior dimensions of the distal femur of female patients was smaller than what was observed in male patients. Based on that data, we conducted a study on Thai female cadavers, as females represent the most common subgroup of TKA patients.…”

“…Among South East Asian mongoloid population, Indonesian has similar morphometry compared with Thai population. Indonesian and Thai had similar size and large femur aspect ratio (Chaichankul et al, 2011). Large femur ratio reflects the shape of the distal femur, and it means that the shape of distal femur was mediolaterally oval.…”

SUMMARY:The objective of this study was to design custom-made prosthesis in a certain population, the morphometry needs to be measured. The results of this study were expected to provide basic data to design the ideal size of the total knee arthoplasty prosthesis for Indonesian population. This was an anthropometric study conducted on 100 healthy Indonesian population based on Computer Tomographic (CT) imaging on the distal femur resected surface. The parameters being used were Femoral Medio Lateral (fML) length, Femoral Antero Posterior (fAP) length, Femoral Medial Antero Posterior (fMAP) length, Femoral Lateral Antero Posterior (fLAP) length, and Femoral Aspect Ratio (FR). We found that the mean fAP and fML were 54.60±5.71 and 65.98±6.51, respectively. The morphometry of the distal femur were significantly different between male and female (male have larger build), however one of parameters showed different result: fLAP. This study showed that Indonesian people have smaller build compared with their Western counterpart. The proposed dimensions can be used as the basic data to design the ideal size of the custom-made knee arthoplasty prosthesis for Indonesian population.

“…Gender differences in the anatomy of the distal femur are well documented (Conley et al 2007, Yue et al 2011a, b, Yan et al 2012, Zeng et al 2012). Women tend to have a less prominent anterior condyle (Conley et al 2007, Fehring et al 2009), a higher quadriceps angle (Q-angle) (Hsu et al 1990, Woodland et al 1992), and a reduced mediolateral to anteroposterior aspect ratio (Chin et al 2002, Chaichankul et al 2011). Investigators have found that standard unisex knee prostheses may not equally match the native anatomy in male and female knees (Clarke and Hentz 2008, Yan et al 2012).…”

No clinical benefit of gender-specific total knee arthroplasty

Background and purposeThere is no consensus regarding the clinical relevance of gender-speciﬁc prostheses in total knee arthroplasty (TKA). We summarize the current best evidence in a comparison of clinical and radiographic outcomes between gender-speciﬁc prostheses and standard unisex prostheses in female patients.MethodsWe used the PubMed, Embase, Cochrane, Science Citation Index, and Scopus databases. We included randomized controlled trials published up to January 2013 that compared gender-speciﬁc prostheses with standard unisex prostheses in female patients who underwent primary TKAs.Results6 trials involving 423 patients with 846 knee joints met the inclusion criteria. No statistically significant differences were observed between the 2 designs regarding pain, range of motion (ROM), knee scores, satisfaction, preference, complications, and radiographic results. The gender-specific design (Gender Solutions; Zimmer Inc, Warsaw, Indiana) reduced the prevalence of overhang. However, it had less overall coverage of the femoral condyles compared to the unisex group. In fact, the femoral prosthesis in the standard unisex group matched better than that in the gender-speciﬁc group.InterpretationGender-speciﬁc prostheses do not appear to confer any beneﬁt in terms of clinician- and patient-reported outcomes for the female knee.
