Materials and Methods
Between April 1987 and May 2004, 7890 primary TKAs were performed at our institution for the treatment of osteoarthritis with a posterior cruciate-retaining TKA (AGC; Biomet, Warsaw, Ind) independent of diagnosis or deformity and based on surgeon preference. Data were unavailable in 564 (6.7%) knees, which were considered lost to follow-up, leaving 7326 TKAs followed for this study. Of the patients, 59.5% were women. The mean age was 69.2 years (range, 24-93 years) (Table 1). The institutional
Results
Preoperative KSS was greater in men (P = .0014). No sex differences in KSS were noted postoperatively at any follow-up (Fig. 1). Women, however, experienced a greater improvement in KSS after TKA (P = .0066).
Preoperative PS was also greater (less pain) in men (P = .0005). Postoperatively, men also had consistently higher PS (P < .0001). The change in PS before and after TKA was not statistically different (Fig. 2).
Similarly, FS was greater in men before operation (P < .0001). Throughout the
Discussion
Most TKAs are performed in women [1], [11], [12] as demonstrated in this study, in which 59.5% of the TKAs were performed in women. The ratio between the anterior-posterior and medial-lateral dimensions of the distal femur as measured from its distal portion is often different between men and women [2], [3], [5], [6], [7]. In a study by Hitt et al [3], many current femoral TKA prostheses were evaluated using the dimensions of these prostheses compared with anatomical measurements of knees

Social Determinants of Health Disparities Increase the Rate of Complications After Total Knee Arthroplasty
2023, Journal of ArthroplastyDemographics are no clinically relevant predictors of patient-reported knee osteoarthritis symptoms - Comprehensive multivariate analysis
2023, Journal of OrthopaedicsCitation Excerpt :Studies have suggested that this subjectivity may be structurally related to demographic factors including age, sex, obesity and physical health status.12–14 However, to date, evidence on pre-operative comparisons is weak for its small sample sizes,15 statistical limitations including secondary analyses and missing adjustment for covariates,15,16 and data collection methods prone to error,15,17,18 e.g. incomplete questionnaires and transcription into electronic records.19 High-quality studies in representative samples are lacking to comprehensively define structural differences in patients assessments of symptoms between demographic groups.
Outcomes Vary Significantly Using a Tiered Approach to Define Success After Total Knee Arthroplasty
2022, Journal of ArthroplastyClinical Course of Pain and Function Following Total Knee Arthroplasty: A Systematic Review and Meta-Regression
2021, Journal of ArthroplastyCitation Excerpt :Figure 2A–F and Supplement Table 5 present the trajectories and estimates for all included pain outcomes. The clinical course of function following TKA was reported in 172 unique cohorts including 55,873 patients [12-204]. Of these, the following function instruments were used and included in the meta-regression: KSS function (N = 86) [13,14,16,19,20,26,28,32–36,42,45,47,49,55,59,60,62–64,66,72–76,78,80–82,84,88–90,94,95,97–101,103–105,111,113,116,120,121,125,128,129,132,133,137,140,143–145,147,150,156,158,160,163,165,169–171,175–179,182,184–186,191,197–199,201], OKS function (N = 39) [12,17,28,31,33,34,40,49,56,58,60,62,63,66–69,83,84,86,91,99,104,105,117,120,136,138,139,144,149,152,167,168,173,178,192–194], WOMAC function (N = 20) [18,21,30,53,54,59,70,74,85,90,92,108,118,119,145,153,162,164,172,195], WOMAC total score (N = 18) [21,22,37,48,55,57,59,60,65,92,100–102,115,137,164,182,188], and Hospital for Special Surgery (HSS) total score (N = 16) [22,29,79,89,93,102,109,110,141,159,164,166,174,196,200,204].
Gender Differences for Hip and Knee Arthroplasty: Complications and Healthcare Utilization
2019, Journal of ArthroplastyCitation Excerpt :As degenerative joint disease is identified as a common cause of disability, the rate of total joint arthroplasty procedures is growing rapidly [1–3]. While gender differences have been sporadically reported in regard to preoperative presentation, intraoperative variables, and postoperative outcomes, there has been a paucity of data specifically comparing gender cohorts [6–16]. This study aimed to identify the impact of gender on clinical outcomes after total joint arthroplasty to further characterize healthcare utilization and complications.
