AbstractTechniques allow assessment of preoperative offset in hip arthroplasty. This study assessed femoral rotation in preoperative offset templating using a cadaveric model. Ten femurs were imaged at degrees of rotation. Offset was measured. A generalizable equation predicting change in offset was derived with a curvilinear model. Statistically significant differences at rotational positions were found. For 30 degrees of internal rotation, 2.1 mm change in adjusted mean offset existed; for 30 degrees of external rotation, 8.4 mm change existed. Improved awareness of malrotation of the proximal femur and templating adjustments may improve total hip arthroplasty outcomes. This study reflects level of evidence III.

Abstract Background This study aims to evaluate postoperative pain and functional and clinical outcomes of anterolateral supine (ALS) and posterolateral (PL) approaches for primary total hip arthroplasty. Materials and methods We retrospectively examined the joints of 110 patients who underwent primary total hip arthroplasty (THA). The ALS group was compared with the PL group using the pain visual analog scale (VAS) and narcotic consumption as pain outcomes. Functional outcomes included postoperative range of motion (ROM) of hip flexion, day on which patients could perform straight leg raising (SLR), day on which patients began using a walker or cane, duration of hospital stay, rate of transfer, and strength of hip muscles. Clinical outcomes included pre and postoperative Harris Hip Scores. Results No significant differences were found in the pain VAS scores or narcotic consumption between the two groups. The PL group could perform SLR earlier than the ALS group (P < 0.01). The ALS group started using a cane earlier (P < 0.01) and had a shorter hospital stay (P < 0.01) than the PL group. Degrees of active ROM of flexion at postoperative day (POD) 1 were significantly lower in the ALS group than in the PL group (P < 0.01). Regarding hip muscle strength, hip flexion was significantly weaker in the ALS group than in the PL group until 1-month POD (P < 0.01). External rotation from 2 weeks to 6 months postoperatively was significantly weaker in the PL group than in the ALS group (P < 0.01). Conclusion The ALS approach was more beneficial than the PL approach because ALS enabled better functional recovery of the strength of external rotation, improved rehabilitation, and involved a shorter hospital stay. Level of Evidence Level IV retrospective observational study.

Abstract Background: To investigate the postoperative outcome of decompresed hip following contralateral replacement in patients with bilateral osteonecrosis of the femoral head (ONFH). M ethods: This study retrospectively reviewed 30 patients with bilateral ONFH who underwent one-stage total hip arthroplasty (THA) and multiple drilling decompression from February 2014 to February 2016. For all patients, alendronate was prescribed. Postoperative Harris Hip Scores (HHSs), Oxford Hip Scores (OHSs), Self-Administered Patient Satisfaction (SAPS), hip internal and external rotation angles, and the time of one-leg standing were evaluated. All patients were followed up for an average of 30.33 months (ranged from 8 months to 48 months). Results: Twenty-four patients had no progression or collapse on radiographic evaluation within 2 years postoperatively. The following scores of the decompressed sides were significantly lower than those of the replaced sides: HHSs (mean: 96.5 versus 98.25, P <0.05), SAPS (mean: 96.35 versus 99.48, P <0.001), internal rotation (mean: 27.58° versus 30.50°, P <0.05), and the time of single-leg standing (mean: 24.17 s versus 31.83 s, P <0.05). There was no significant difference in OHSs and external rotation between the sides. The remaining 6 patients underwent two-stage THA on the decompressed sides within 2 years. Four of them underwent THA for severe pain and femoral head collapse. The other 2 patients showed no progression on radiographic evaluation but complained of an uncomfortable feeling in the joint. Conclusions: One-stage THA and multiple drilling decompression are effective surgical procedures for bilateral ONFH at different stages. However, a few patients with no progression on radiographic evaluation may require two-stage THA on the decompressed sides because of more pain, poorer internal rotation, and weaker gluteal muscle strength when compared with the replaced sides.

AbstractHospital adverse events remain a significant issue; even “minor events” may lead to increased costs. However, to the best of our knowledge, no previous investigation has compared perioperative events between the first and second hip in staged bilateral total hip arthroplasty (THA). In the current study, we perform such a comparison. A retrospective chart review was performed on a consecutive series of 172 patients (344 hips) who underwent staged bilateral THAs performed by two surgeons at a single institution (2010–2016). Based on chronological order of the staged arthroplasties, two groups were set apart: first-staged THA and second-staged THA. Baseline-demographics, length of stay (LOS), discharge disposition, hospital adverse events, and hospital transfusions were compared between groups. Statistical analyses were performed using independent t-tests, Fisher's exact test, and/or Pearson's chi-squared test. The mean time between staged surgeries was 465 days. There were no significant differences in baseline demographics between first-staged THA and second-staged THA groups (patients were their own controls). The mean LOS was significantly longer in the first-staged THA group than in the second (2.2 vs. 1.8 days; p < 0.001). Discharge (proportion) to a facility other than home was noticeably higher in the first-staged THA group, although not statistically significant (11.0 vs. 7.6%; p = 0.354). The rate of hospital adverse events in the first-staged THA group was almost twice that of the second (37.2 vs. 20.3%; p = 0.001). There were no significant differences in transfusion rates. However, these were consistently better in the second-staged THA group. When compared with the first THA, our findings suggest overall shorter LOS and fewer hospital adverse events following the second. Level of Evidence Level III.

Purpose: Total hip arthroplasty (THA) for high-riding hips is a complex procedure and the requirement for subtrochanteric osteotomy (STO) is an important decision that needs to be taken preoperatively. STO renders this complex surgery even more complicated and there are no guidelines to determine the STO requirement. In this study, the outcomes of THA for patients with high-riding hips were evaluated and a practical classification system is proposed to predict any osteotomy requirement. Methods: A retrospective evaluation was made of 79 hips of 76 patients who underwent THA for high-riding hip dysplasia. The amount of shortening in patients with STO and in patients without STO was compared. All patients were evaluated in respect of Harris hip score, operating time, erythrocyte suspension need, and actual limb length discrepancy. Preoperative radiographs were classified into four types according to the ratio of the distance between the lesser trochanter and the ischial tuberosity with pelvic height (LT-IT/P) to grade the degree of dislocation. Results: The mean follow-up was 30 ± 6.54 months. STO was applied to 47 (60%) hips and not to 32 (40%). There was no statistically significant difference between the groups in respect of the functional scores. STO prolonged the operating time and increased the need for blood transfusion ( p = 0.026, p < 0.001, respectively). When the LT-IT/P index was <0.19 (type 1), no additional surgical approach was required for reduction, at 0.19–0.29 (type 2), the head can be safely reduced with additional reduction methods, and when >0.3 (type 3), a shortening osteotomy will most likely be required. The rate of complications is increased if LT-IT/P is >0.4 (type 4). Conclusion: STO adjunct to THA increases the rate of complications. This practical classification system may guide the surgeon in the decision of whether an STO should be added to the procedure or not. Level of evidence: Level III, clinical trial
