The study group yielded an improvement in mean post-operative ROM of 21¡ã at 12 months, whereas the mean improvement in ROM among the control group was 11¡ã. Thus, the study group had a 10¡ã increased ROM improvement (91%) over the control group (p£¿=£¿0.00060). In addition, 100% of the subjects with gender specific high-flexion implants achieved greater or equal ROM post-operatively compared to 82% for the control cohort. Lastly, women who exhibited greater pre-operative ROM and lower body mass index (BMI) were found to benefit the most with the gender specific prosthesis.Our study demonstrates that among subjects with a normal BMI, the gender specific high-flexion knee implant is associated with increased ROM as compared to the non-gender specific non-high-flexion implant designs. %K Osteoarthritis %K Gender-specific high-flexion knee prosthesis %K Total knee arthroplasty %K Body mass index %K Range of motion %U http://www.josr-online.com/content/7/1/22/abstract
