“…To minimise confounding factors, propensity score matching was used to match bony ankylosed to nonankylosed hips. Using logistic regression, propensity scores were calculated using the ve variables of age, sex, height, weight, and body mass index, which were selected based on previous studies [7][8][9][10][11].…”

Background Total hip arthroplasty (THA) is one of the most effective treatments for hip arthritis. However, postoperative outcomes of THA in patients with bony ankylosed hips remain inconclusive. We aimed to examine the postoperative results of THAs for bony ankylosed hips using propensity score matching. Methods A propensity score was calculated using logistic regression analysis for a bony-ankylosed group (40 hips, 38 patients) and a non-ankylosed (control) group (829 hips, 729 patients). Patients were followed up for more than 10 years after primary THA. The propensity score used five covariates: age, sex, height, weight, and body mass index. Propensity matching was performed, with each bony ankylosed hip being matched to a non-ankylosed control hip. The clinical outcomes of the Japanese Orthopaedic Association (JOA) hip scores and complications were investigated. Results The propensity-matched population consisted of 40 bony ankylosed hips (38 patients) and 40 hips (40 patients) of matched controls. In both groups, the postoperative JOA hip scores at the last follow-up significantly improved compared to the preoperative scores. The JOA hip scores at the last follow-up for all components in the bony-ankylosed group were significantly lower than those in the control group. The number of hips with postoperative complications was significantly higher in the bony-ankylosed group than that in the control group. Conclusions THA for patients with bony ankylosed hips achieved positive results, including improved JOA hip scores; however, these scores were inferior to those observed in patients with non-ankylosed hips. This should be preoperatively communicated to patients with bony ankylosed hips who undergo THA.

“…Although THA increases range of motion and to a lesser extent spatiotemporal parameters compared to preintervention status ( Miki et al, 2004 ; Queen, Butler, et al, 2011 ), the surgical hip generally is restricted relative to the nonsurgical hip and the majority of patients show asymmetric loading patterns that are associated with deficits in balance and proprioception that persist for at least 2 years following surgery ( Bennett et al, 2008 ; McCrory et al, 2001 ; Queen et al, 2015 ; Queen, Watters, et al, 2011 ). Few studies have examined sex-specific differences in gait following THA and those studies did find significant though limited differences between men and women before and after surgery ( Brunner & Foucher, 2018 ; Foucher, 2016 ; Peng et al, 2021 ).…”

Background and Objectives Total hip replacement (THA) is a common surgical procedure in older adults (65 years or older). THA has high patient satisfaction, but little is known about balance and mobility limitations after surgery and if outcomes are sex-specific. To evaluate post-THA asymmetry during unilateral standing and a dynamic balance and reach test and test the hypotheses that balance performance would be decreased on the surgical limb and that balance deficits would be greater in women than men. Research Design and Methods Primary, unilateral THA (70 male, 57 female) patients completed a bilateral 10-second single leg stance test. Sixty male but only 34 female participants could maintain unilateral balance for 10 seconds or greater. The cohort who successfully completed the 10-second single limb stance test then completed a Lower Quarter Y-Balance Test (YBT-LQ) in which the maximum anterior (ANT), posteromedial (PM) and posterolateral (PL) reach distances were obtained bilaterally and used to calculate the asymmetry score. All variables were compared using a mixed-model repeated-measures ANOVA (sex by limb), while independent samples t-tests were used to assess sex-specific asymmetry. Results Women failed single leg stance at a higher rate than men (85.7% vs. 59.6%; p=0.001). Reach distance was different between limbs for all reach directions (p<0.004) with greater reach distance on the non-operative limb for all patients. Men had a greater reach distance in the ANT (p=0.004), and PM (p=0.006) directions. Discussion and Implications These results indicate that post-THA the operative limb and female patients have greater balance limitations. These results are novel and reveal sex-specific patterns that emphasize the need for sex-specific post-operative rehabilitation programs to improve long-term outcomes, especially in older adults with muscle weakness and balance deficits.
