Background: Femoroacetabular impingement (FAI) can lead to hip pain and early joint degeneration. There have been few reports to date on the outcomes of hip arthroscopy for the treatment of FAI in the military population. Purpose/Hypothesis: The purpose of this study was to compare patient demographics with postoperative outcomes after hip arthroscopy for symptomatic FAI and to identify preoperative risk factors for poor outcomes. The hypothesis was that certain preoperative patient characteristics will be predictive of poorer outcomes and that lower outcomes scores will be associated with a higher likelihood of medical separation from the military. Study Design: Case series; Level of evidence, 4. Methods: Retrospective chart review of active-duty and dependent patients older than 18 years who underwent hip arthroscopy for symptomatic FAI from 2009 to 2014 at a single institution. Results: A total of 469 (309 males and 160 females) surgeries were performed on 456 active-duty personnel and 13 dependent civilians, with a mean 2.5-year follow-up. Overall, 39% (n = 179) were able to return to duty (RTD), 18% (n = 82) were medically cleared to return to normal daily activities but did not remain on active duty, and 43% (n = 195) required referral to the Disability Evaluation System (DES). Increasing rank and male sex were positive predictors and Axis 1 psychiatric diagnosis, revision surgery, concomitant psoas tenotomy, multiple medical comorbidities, and complaints of generalized pelvic pain were negative predictors for returning to duty. US Marine Infantry and Special Forces showed improved RTD rates (50%-86%) compared with administrative, more sedentary, occupations (22%). On average, Single Alpha Numeric Evaluation (SANE) and visual analog scale (VAS) scores improved after surgery, with SANE scores improving 37 ± 28 points and VAS scores improving 2.6 ± 2.5 points. The mean postoperative SANE and VAS scores differed significantly between the RTD group and those not returning to duty; 87 and 1.2 points compared with 69 and 3.6 points, respectively (P < .0001). Conclusion: Hip arthroscopy for the treatment of symptomatic FAI effectively improves pain symptoms and self-reported overall function but shows a much lower than expected return to full, unrestricted active duty in the general active-duty military population. Underlying psychiatric diagnoses, female sex, and more sedentary occupations are associated with lower RTD rates. Furthermore, lower postoperative SANE and VAS scores are associated with lower RTD rates. Only the more active and elite components of the military study population showed RTD rates consistent with previously reported outcomes of return to competitive sports after hip arthroscopy for FAI.

Few studies describe the relationship between obesity and groin hernias. Our objective was to investigate the correlation between body mass index (BMI) and groin hernias in a large population. Patients with the diagnosis of inguinal or femoral hernia with and without incarceration or strangulation were identified using the Kaiser Permanente Southern California regional database including 14 hospitals over a 7-year period. Patients were stratified by BMI. There were 47,950 patients with a diagnosis of a groin hernia--a prevalence of 2.28 per cent. Relative to normal BMI (20-24.9 kg/m(2)), lower BMI was associated with an increased risk for hernia diagnosis. With increasing BMI, the risk of incarceration or strangulation increased. Additionally, increasing age, male gender, white race, history of hernia, tobacco use history, alcohol use, and higher comorbidity index increased the chance of a groin hernia diagnosis. Complications were higher for women, patients with comorbidities, black race, and alcohol users. Our study is the largest to date correlating obesity and groin hernias in a diverse United States population. Obesity (BMI ≥ 30 kg/m(2)) is associated with a lower risk of groin hernia diagnosis, but an increased risk of complications. This inverse relationship may be due to limitations of physical exam in obese patients. [ABSTRACT FROM AUTHOR]

Early hospital readmission among vascular surgery patients is a focus of Medicare’s new reimbursement structure. We aim to identify factors associated with 30-day readmission after lower extremity interventions to treat peripheral artery disease (PAD). Retrospective analysis of 174 consecutive patients discharged from the vascular surgery service between January 1, 2011, and July 31, 2012, after procedures for lower extremity PAD was performed. Of 174 patients, 37 were readmitted within 30 days of discharge. There were no significant differences in baseline characteristics between the readmitted and the nonreadmitted groups. In a multivariate logistic regression model, urgent operation and advanced chronic kidney disease (CKD) were associated with increased risk of 30-day readmission. The most common reasons for readmission were infection of the surgical site or index limb (18 of 37), followed by unresolved limb symptoms (13 of 37). The 30-day readmission is frequent after lower extremity interventions to treat PAD. Urgent operative intervention and advanced CKD appear to be risk factors for early hospital readmission.

Background: Functional instability after anterior cruciate ligament injury can be successfully treated with ligament reconstruction. However, the associated meniscus and cartilage lesions often cannot be repaired and may have long-term detrimental effects on knee function.Purpose: The authors used the large database within the Kaiser Permanente Anterior Cruciate Ligament Reconstruction Registry to evaluate time to surgery, age, and gender as risk factors for meniscus and cartilage injury and associations with meniscus repair rates in patients.Study Design: Cross-sectional study; Level of evidence, 3.Methods: A retrospective review of the Kaiser Permanente Anterior Cruciate Ligament Reconstruction Registry was performed. The associations between time to surgery, age, and gender with meniscus and cartilage lesions and meniscus repair were analyzed using binary logistic regression modeling to calculate odds ratios (ORs) while adjusting for potential confounding variables.Results: A total of 1252 patients met the inclusion criteria. The risk of medial meniscus injury increased only with time to surgery (6–12 months: OR = 1.81, 95% confidence internal [CI] 1.29-2.54, P = .001; and >12 months: OR = 2.19, 95% CI 1.58-3.02, P < .001). The risk of lateral meniscus injury decreased only with female gender (OR = 0.65, 95% CI 0.51-0.83, P = .001). The risk of cartilage injury increased with age (OR = 1.05 per year, 95% CI 1.04-1.07, P < .001) and time to surgery >12 months (OR = 1.57, 95% CI 1.12-2.20, P = .009), but decreased with female gender (OR = 0.71, 95% CI 0.54-0.92, P = .009). Medial meniscus repairs relative to medial meniscus injury decreased with increasing time to surgery (3-6 months: OR = 0.61, 95% CI 0.37-1.00, P = .050; and >12 months: OR = 0.41, 95% CI 0.25-0.67, P < .001) and increasing age (OR = 0.96 per year, 95% CI 0.94-0.98, P < .001).Conclusion: Increased risk of medial meniscus injury and decreased repair rate were strongly associated with increasing time to surgery. Increased risk of cartilage injury was associated with increasing age, increasing time to surgery, and male gender. [ABSTRACT FROM AUTHOR]
