RESULTS The DK nanocrush was practically feasible and resulted in full ostial coverage. CFD analysis demonstrated minimally disturbed blood flow. The technique was successfully utilised in 9 patients with bifurcation lesions with excellent angiographic outcomes and no adverse events over 12 months. CONCLUSIONS The DK nanocrush technique may represent the ultimate refinement of the original crush technique with a number of practical and theoretical advantages. It remains to be tested against other bifurcation techniques in prospective trials. BACKGROUND There is growing recognition of the importance of patient-reported outcome measures and assessment of patient satisfaction in the evaluation of outcomes following surgical interventions. This study aimed to evaluate patient-reported outcomes and complication rates after total hip arthroplasty following joint preservation surgery for hip dysplasia. METHODS Patient-reported outcomes and complication rates of 85 hips with previous joint preservation surgery (salvage group) were compared with those of 1279 hips without joint preservation surgery (primary arthroplasty group). As a patient-reported outcome measure, the Japanese Orthopedic Association Hip Disease Evaluation Questionnaire was used to evaluate the hip condition both preoperatively and 12 months postoperatively. Operative data and postoperative (within 12 months) complications were investigated. RESULTS The salvage group had a longer operative time (56.8 vs 44.9 minutes, P less then .001) and a higher total complication rate (5.9% vs 1.1%, P less then .001). Additionally, the salvage group exhibited a lower degree of improvement in the visual analog scale value for satisfaction (75.1 vs 83.1 mm, P = .011), the pain and movement category scores, and the total score of the Japanese Orthopedic Association Hip Disease Evaluation Questionnaire (14.2 vs 16.2, P = .031; 13.7 vs 16.0, P = .005; and 42.3 vs 47.9, P = .007, respectively) compared with the primary arthroplasty group. CONCLUSION This study demonstrated a lower rate of improvement in patient satisfaction and worse self-reported outcomes in the salvage group. Furthermore, these patients had a longer operative time and a higher risk of operative complications. BACKGROUND Urinary bladder catheters are potential sources of infection after total hip arthroplasty (THA). Therefore, the goal of this study was to determine if intermittent catheterization provides a decreased risk of postoperative urinary tract infections (UTIs) compared with indwelling catheterization in THA patients. METHODS Patients undergoing THA at 15 hospitals within a large health system were prospectively collected between 2017 and 2019 and then stratified based on catheterization technique no-catheter; indwelling catheter-only; intermittent catheter-only; and both intermittent and indwelling catheter. Patient demographics, medical comorbidities, anesthesia types, and postoperative UTIs were assessed. Independent Student t-tests were used to perform univariate analyses for the catheterization groups. Multiple linear regression models were used to compare the different groups while controlling for confounding variables. RESULTS There were a total of 7306 THA patients recorded with 5513 (75%) no-catheter, 1181 (16%) indwelling catheter-only, 285 (3.9%) intermittent catheter-only, and 327 (4.5%) indwelling and intermittent catheterization patients. A total of 580 patients experienced postoperative UTI. Urinary bladder catheterization increased the risk of postoperative UTIs (P less then .001) in univariate analyses. Multiple linear regression models showed that indwelling catheter-only (OR 2.178, P less then .001), intermittent catheterization (OR 1.975, P = .003), and both indwelling and intermittent (OR 2.372, P = .002) were more likely to experience UTIs compared with no catheters. CONCLUSION This study found that patients treated with indwelling catheterization, wit
