The risk factors and timing for disease progression in adolescents and young adults have not been fully defined. This study aimed to determine the prevalence of and risk factors for contralateral hip pain and surgery after periacetabular osteotomy (PAO) on a dysplastic hip.</p><p><strong>Methods: </strong>Patients undergoing unilateral PAO for DDH were followed for at least 2 years and categorized into contralateral pain and no-pain groups and contralateral surgery and no-surgery groups. Pain was defined with the modified Harris hip score. Univariate analysis tested group differences in demographics, radiographic measures, and range of motion. Kaplan-Meier survival analysis was used to assess pain development and surgery in the contralateral hip over time. Multivariable regression identified risk factors for contralateral pain and surgery. Contralateral pain and surgery predictors were secondarily assessed after categorization of the contralateral hips as dysplastic, borderline, and non-dysplastic and in subgroups based on the lateral center-edge angle (LCEA) and acetabular inclination (AI) in 5° increments.</p><p><strong>Results: </strong>One hundred and eighty-four patients were followed for a mean of 4.6 ± 1.6 years (range, 2.0 to 8.8 years), during which 51% (93) reported contralateral hip pain and 33% (60) underwent contralateral surgery. Kaplan-Meier analysis predicted 5-year survivorship of 49% with contralateral pain development as the end point and 66% with contralateral surgery as the end point. Painful hips exhibited more severe dysplasia compared with no-pain hips (LCEA = 16.5° versus 20.3°, p < 0.001; AI = 13.2° versus 10.0°, p < 0.001). AI was the sole predictor of pain, with every 1° increase in the AI raising the risk by 11%. Surgically treated hips also had more severe dysplasia (LCEA = 14.9° versus 20.0°, p < 0.001; AI = 14.7° versus 10.2°, p < 0.001) and were in younger patients (21.6 versus 24.1 years, p = 0.022). AI and a maximum alpha angle of ≥55° were predictors of contralateral surgery.</p><p><strong>Conclusions: </strong>At 5 years after hip PAO, approximately 50% of contralateral hips will have pain and approximately 35% can be expected to need surgery. More severe dysplasia, based on the LCEA and AI, increases the risk of contralateral hip pain and surgery, with AI being a predictor of both outcomes.

One method to assess value is through patient-level value analysis (PLVA). To our knowledge, this tool has not previously been implemented in the setting of total hip arthroplasty (THA). The purposes of this study were to perform PLVA for a 1-year episode of care among patients undergoing primary THA and to identify characteristics that affect value in a metropolitan health-care system.</p><p><strong>Methods: </strong>The patient-reported outcome (PRO) measure database of the institution was queried for all primary THAs from 2018 to 2019. The PRO measure that was utilized was the Hip disability and Osteoarthritis Outcome Score, Joint Replacement (HOOS-JR). Cost was evaluated with use of time-driven activity-based costing (TDABC) for a 1-year episode of care (consisting of the day of surgery, inpatient stay, discharge facility, postoperative appointments, and physical therapy). The primary outcome was the 1-year value quotient, or the ratio of the 1-year change in HOOS-JR to the cost of the episode of care (VHOOS). The value quotient was compared among all included patients and evaluated for variables that may affect the overall value of the episode of care.</p><p><strong>Results: </strong>In total, 480 patients were included in the analysis. The mean improvement in the HOOS-JR was +34.9 ± 16.1 (95% confidence interval [CI]: 33.5, 36.3). The mean cost was $13,835 ± $3,471 (95% CI: $13,524, $14,146). The largest contributor to cost was implants (39.0%), followed by post-recovery care (i.e., inpatient stay and specialized nursing facilities; 24.1%). Change in the HOOS-JR was poorly correlated with the cost of care (r = -0.06; p = 0.19).

However, conventional manual measurement methods are often subjective, leading to variations in results among observers. Our goal was to develop an automated and dependable method for determining the retrograde SRS corridor.</p><p><strong>Methods: </strong>We developed an automated technique that utilized a computed tomography (CT) image-based search algorithm to identify the retrograde SRS corridor with the maximum diameter. We evaluated the reliability of this automated approach in comparison to a manual method using 17 pelves. Subsequently, we used both methods to measure the diameter, length, and orientation of the retrograde SRS corridor in 204 pelves in a Chinese population and assessed the intra- and interobserver agreement of each method by calculating the root-mean-square error (RMSE) and constructing Bland-Altman plots. We determined the screw applicability (percentages of hemipelves that could be treated with specific sizes of screws) for each method. Additionally, we investigated potential factors influencing the corridor, such as sex, age, height, and weight, through regression analysis.</p><p><strong>Results: </strong>The intra- and interobserver intraclass correlation coefficients (ICCs) for the automated method (0.998 and 0.995) were higher than those for the manual approach (0.925 and 0.918) in the assessment of the corridor diameter. Furthermore, the diameter identified by the automated method was notably larger than the diameter measured with the manual method, with a mean difference and RMSE of 0.9 mm and 1.1 mm, respectively. The automated method revealed a significantly smaller corridor diameter in females than in males (an average of 7.5 and 10.4 mm, respectively). Moreover, use of the automated method allowed 80.6% of the females to be managed with a 4.5-mm screw while a 6.5-mm screw could be utilized in 19.4%, surpassing the capabilities of the manual method. Female sex had the most substantial impact on corridor diameter (β = -0.583).</p><p><strong>Conclusions: </strong>The automated method exhibited better reliability than the manual method in measuring the retrograde SRS corridor, and showed a larger corridor diameter for screw placement. Females had a significantly smaller corridor diameter than males.
