Background: Hip fractures are serious injuries associated with relatively high mortality rates and disabilities, commonly seen in elderly persons. There is an ongoing debate regarding the advantages of various hip arthroplasty devices. This study aimed to analyze the long-term advantages of 2 different surgical procedures and assess if the dislocation rate, Harris Hip Score (HHS), and functional independence measure (FIM) are more favorable in dual mobility (DM) than those in hemiarthroplasty (HA). Hypothesis: Dual mobility procedures provide better postoperative outcomes than HA in terms of HHS, FIM, and dislocation rate. Materials and Methods: The survey was a prospective, comparative interventional single-blinded study performed at the University Clinical Center of Kosovo, a tertiary health-care institution. A total of 94 patients underwent DM or conventional bipolar HA for repair of displaced femoral neck fractures within 2 weeks of injury. Primary outcomes were postoperative dislocation rate, FIM, and HHS. Secondary outcomes included duration of surgery, estimated intraoperative blood loss, time to first postoperative full weight-bearing, time to walking ability with and without crutches, mortality rate, and postoperative infection rate. Results: There were no significant differences for most parameters between the groups. We found a significant difference in the dislocation rate between the 2 groups, wherein there were no dislocations in the DM group and 3 dislocations in the HHS group (0% vs 6.4%). In terms of postoperative HHS at 12 months and 3 years, DM provided better outcomes (<0.034 and <0.014, respectively). Discussion: Dual mobility compares favorably to HA in terms of dislocation rate and HHS, while no difference was found for FIM. In order to have a more complete overview, we recommend more intense long-term studies including several heterogeneous parameters to compare the clinical outcomes between DM and HA. Level of evidence (with study design): Level II.

Purpose: To evaluate femoral and acetabular morphology in patients who underwent anterior cruciate ligament reconstruction (ACLR). Methods: A retrospective review of a prospectively collected ACL registry was performed to identify patients with pelvis radiographs before undergoing either primary or revision ACLR between January 2010 and August 2020. Alpha angle (AA), head-neck offset ratio (HNOR), lateral center edge angle (LCEA), and crossover sign (COS) were measured on the operative side. Values were compared to a negative control group that did not significantly differ in age, sex, or body mass index. Univariate analysis and Pearson's correlation coefficient were used to compare groups with significance defined as P < .05. Results: In total, 114 patients were included (ACL, n ¼ 38; control, n ¼ 76). Eleven primary and 27 revision ACL reconstructions were identified. The mean AA in patients undergoing primary ACL reconstruction was higher than control (67.45 AE 11.30 vs 51.5 AE 10.8 , P < .001). A significantly elevated AA was also found in those undergoing revision ACL surgery (61.8 AE 7.51 vs 51.5 AE 10.8 , P < .001). In addition, the HNOR was significantly lower in the ACL group (0.12 AE 0.03 vs 0.14 AE 0.04, P ¼ .0304). Acetabular morphology was similar between groups (LCEA, ACL 31.97 AE 5.04 vs control 30.01 AE 5.17 , P ¼ .0549; COS, ACL 9 of 38 (23.7%) vs control 18 of 76 (23.7%), P ¼ 1.00). Conclusion: An association exists between radiographic cam morphology of the hip and patients who previously underwent ACLR. Level of Evidence: III, retrospective comparison study.
