Non–Sex-Specific Total Knee Arthroplasty: A Review of 1000 Cases Comparing Men and Women

Recent publicity concerning sex-specific knee arthroplasties and their potential advantages have caused us to analyze prospectively collected data on 1000 consecutive unilateral knee arthroplasties. The knee design used was a non–sex-specific knee arthroplasty sized in the anteroposterior dimension of the femur and sized specifically and independently for the tibia. We used a cemented posterior stabilized design with 1-mm incremental polyethylene spacers. Women represented 70% of the cases performed. Men and women were well-matched for anesthetic risk (age: women 69 years; men, 67 years), with the body mass index being slightly higher for the women. We compared data at 1 year after knee arthroplasty.
