CROW ZERO 1 FINAL BATTLE SOFTWARE
Preoperative planning was performed for all THAs in both groups with the use of a computed tomography (CT)-based three-dimensional (3-D) templating and navigation software (CT-based Hip, version 1.0 or 1.1 Stryker Navigation, Freiburg, Germany). One patient (2 hips) who underwent THA with femoral shortening osteotomy on one side and without on the other side was excluded when considering the influence of femoral shortening osteotomy. Ten patients (15 hips) underwent THA with femoral shortening osteotomy (FO group), while 12 patients (15 hips) underwent THA without femoral shortening osteotomy (N-FO group). To investigate the influence of femoral shortening osteotomy, the H group was divided according to whether femoral shortening osteotomy was performed or not.

Data matching involved matching for age (☑0 years), sex, body mass index (±5 kg/m 2), and surgical approach (posterior approach). The control group was formed by recruiting data-matched controls per patient in the H group. For the control group, we included 46 patients (64 hips) who underwent primary THA for Crowe type I dysplasia (Fig. Among the questionnaire respondents, 23 patients (32 hips), excluding those with a follow-up period of < 1 year after THA, were enrolled as part of the high hip dislocation group (H group). We sent postal questionnaires to 38 patients (50 hips) who underwent primary THA for high hip dislocation (Crowe type III and IV dysplasia) to evaluate postoperative satisfaction.
CROW ZERO 1 FINAL BATTLE ARCHIVE
All data for this study were obtained from the hospital archive system. During the study period, our institution performed 661 primary THAs. This retrospective case-control study assessed patients who underwent primary THA at a single institution between 20. The purpose of this study was to investigate clinical outcomes, including PROMs after THA for high hip dislocation, of Crowe classification type III and IV dysplasia in comparison with those of Crowe type I dysplasia. In addition, investigating and improving the points of dissatisfaction after surgery may lead to increased satisfaction. It is important to know patients’ expectations before surgery. If the preoperative expectation is not met, satisfaction declines. Therefore, we hypothesized that the patient-reported outcomes, expectations, and dissatisfaction for THA may vary when the chief complaint is different, depending on the degree of pelvic deformity. On the other hand, patients with severe deformity may suffer from not only pain but also leg length discrepancy and joint contractures, as well as consequent changes in posture. Patients with mild deformity experience pain and have restricted range of motion (ROM), which is likely to be the chief complaint. In general, there are various indications for THA, ranging from relatively mild to severe pelvic deformity, such as high hip dislocation. In recent years, with the introduction of femoral shortening osteotomy, some papers have reported relatively stable outcomes. THA for high hip dislocation was thought to be beyond surgical correction in the 1970s. THA is known to be associated with good satisfaction in terms of patient-reported outcome measures (PROMs). The long-term outcomes of total hip arthroplasty (THA) have been excellent. These findings may help explain the effects of THA preoperatively to patients with Crowe type III and IV dysplasia.

The postoperative VAS score was higher in Crowe type III and IV dysplasia than in Crowe type I dysplasia, but no significant differences were detected in the postoperative satisfaction, JOA score, and SF-36 score. Among the questionnaire respondents, 23 patients, excluding those with a follow-up period of 50. We sent postal questionnaires to 38 patients with Crowe type III and IV dysplasia. This retrospective, single-center, single-surgeon case-control study included patients who underwent primary THA between 20.

This study compared patient-reported outcomes after primary THA for Crowe types III, IV and I dysplasia. A few previous studies have investigated patient satisfaction after total hip arthroplasty (THA) according to the degree of pelvic deformity.
