“…The minimal differences observed based on component design are consistent with previous reports that have been unable to demonstrate a difference in PS versus CR TKA [29,41], mobile bearing versus fixed bearing TKA [28,[30][31][32]49], high-flexion versus standard TKA [18], or sex-specific versus no-sex-specific TKA [7,42,59,61]. The poor results in young patients reported by Price et al [50] were achieved with implants and surgical techniques from more than 10 years ago and it is certainly possible that the improved level of satisfaction of our patients may be due, in part, to improvements in surgical technique and component design.…”

Background Few data exist regarding the impact of socioeconomic factors on results of current TKA in young patients. Predictors of TKA outcomes have focused primarily on surgical technique, implant details, and individual patient clinical factors. The relative importance of these factors compared to patient socioeconomic status is not known. Questions/purposes We determined whether (1) socioeconomic factors, (2) demographic factors, or (3) implant factors were associated with satisfaction and functional outcomes after TKA in young patients. MethodsWe surveyed 661 patients (average age, 54 years; range, 18-60 years; 61% female) 1 to 4 years after undergoing modern primary TKA for noninflammatory arthritis at five orthopaedic centers. Data were collected by an independent third party with expertise in collecting healthcare data for state and federal agencies. We examined specific questions regarding satisfaction, pain, and function after TKA and socioeconomic (household income, education, employment) and demographic (sex, minority status) factors. Multivariable analysis was conducted to examine the relative importance of these factors for each outcome of interest.

“…Therefore, some researchers suggested that Asian patients should have specially-designed total knee prosthesis systems. However, many previously published reports [9,24] suggest that the Western-designed total knee prosthesis functioned equally or even better (including, ROM, knee score, and revision rate) in Asian patients than Westerners. I believe that any type of Western or Asian manufactured TKA can accommodate subtle differences in anthropometric knee anatomy between Asian and Westerners, regardless of different culture, gender, activity level, and ethnicity.…”

“…Despite the studies demonstrating their results to be comparable between the genders with standard knees [15][16][17][18][19], it has additionally been demonstrated that results are not significantly different in female whether they get a standard or a gender specific knee [8,[10][11][12][13].…”

“…The greatly contemplated gender specific knee system is Zimmer Gender Solutions NexGen Knee (Zimmer Inc., Warsaw, IN). Such examinations comprised unilateral as well as bilateral studies in female and Indian as well as Tai patients [8][9][10][11][12][13][14]. Although, the available literature, supports a little of gender specific prostheses.…”

Background: Although it is normally perceived that knee morphometry contrasts exist amongst the female as well as male populations, the literature normally disproves the need for gender specific totalknee prosthesis clinically. It was noted that standard/unisex knee performs alike or better in female than male. As of late, high flex knees became accessible, that mechanically accommodate raised flexion but not many studies have contrasted these devices' results in male and female to find out if there is any gender based contrast.
