With improved implants and younger patients undergoing total hip arthroplasty (THA) and hip resurfacing arthroplasty (HRA), there are increased expectations to return to high-impact activities. Recommendations regarding return to running following hip arthroplasty remain unclear. A search of the PubMed database was conducted, and all publications referencing running following THA or HRA published between January 1, 2000, and September 1, 2020, were included in the systematic review. Patient demographics, surgical variables, activity measures, and revision rates were recorded for each study. A total of 225 unique citations were identified, of which four manuscripts met the eligibility criteria. Eighty-nine of 121 (73.6%) preoperative runners returned to running postoperatively. All four studies reported mean postoperative UCLA activity scores of at least nine. More patients returned to running following HRA than THA with lower rates of revision. Further research with longer postoperative follow-up is necessary to provide definitive recommendations for running following arthroplasty procedures.

Limb length discrepancy (LLD) is a frequent complication following total hip arthroplasty (THA) often associated with patient dissatisfaction. Radiographic landmarks are commonly used to determine limb length, but their reliability and accuracy remain to be validated. One-hundred and sixty-two preoperative standing pelvic radiographs from patients undergoing THA were measured using four common landmarks (teardrop, ischial tuberosity, obturator foramen, and iliac crest.) LLD and angular differences between measurements were obtained. Comparison of these landmarks for measuring leg lengths showed weak correlation and wide ranges of LLD for each method - in some cases differing by 30 mm. Angular comparisons showed similar results. Surgeons should be cautioned that there is no standard and reliable method for radiographic measurement of leg length in association with hip replacement surgery and use of these techniques in clinical and research settings should be approached cautiously.

Our study examined whether risk of revision for aseptic loosening following cemented total knee arthroplasty (TKA) is (1) increased with tourniquetless surgery and (2) affected by patient characteristics or surgical factors. Primary cemented TKAs from 2005-2012 with 2-year follow up were analyzed (n = 5,508 with tourniquet; n=101 without). Revision for aseptic loosening was compared between TKA performed with and without a tourniquet. Patient characteristics were recorded. At mean 4.8-year follow up, risk of aseptic loosening was similar between TKA performed with or without a tourniquet (p = 0.3151). Aseptic loosening was more likely in men (p = 0.0018) and patients younger than 50 (p < 0.0001). No difference was observed between cruciate-retaining and posterior-stabilized implants (p = 0.1250). With the numbers available for study, we did not observe an increased risk of aseptic loosening with tourniquetless cemented primary TKA. Patients younger than 50, particularly men, should be counselled on the increased risk of TKA revision for aseptic loosening. (Journal of Surgical Orthopaedic Advances 32(2):111-113, 2023).

Gluteal tendinopathy is a common source of impairment in adults due to degenerative changes in the gluteus medius tendon. We identified patients with gluteal tendinopathy who underwent surgery with a minimum six-month follow up. Radiographs, magnetic resonance images, demographic data, Hip Outcome Score (HOS), Veterans Rand 12-item health survey (VR-12), and a patient survey were reviewed. The cohort consisted of seventeen complete tears and thirty-one partial tears of the gluteal medius tendon (n = 48). Of patients, 72.9% reported satisfaction with surgery and noted 95.5% improvement in symptoms. Patients with partial tears demonstrated 90.0% improvement, while patients with complete tears noted 85% (p = 0.983). The median percent improvement for satisfied patients was 95.00 (85-100) and was significantly different from non-satisfied patients (p < 0.0001). Surgical repair resulted in higher HOS, activities of daily living (ADL), and HOS Sports scores. The majority of patients were satisfied with surgical treatment at follow up, noting near complete resolution in preoperative symptoms.

During the Coronavirus Disease 2019 (COVID-19) pandemic, states implemented social distancing guidelines. This study examines the effect of the severity of lockdown orders on orthopaedic trauma volume. Two institutions, one in a state with strict stay home (SH) orders and one in a state with lax social distancing (SD) orders, were examined. Surgical case counts, total orthopaedic case counts, orthopaedic trauma case counts, institution trauma activations, and mechanism of injury data were collected and compared to control periods. For SH versus SD, total surgical cases decreased 48.6% vs. 62%; orthopaedic cases decreased 51.8% vs. 62%, and orthopaedic trauma cases decreased 34% v. 0%. Orthopaedic trauma cases comprised more of both institutions' total cases. Total surgical cases decreased at both SH and SD, but orthopaedic trauma cases did not decrease at SD. More strict social distancing orders correlate with greater reduction in orthopaedic trauma cases. (Journal of Surgical Orthopaedic Advances 31(4):222-225, 2022).

OpenFDA is an open access database maintained by the United States Food and Drug Administration (FDA) that we queried for adverse events (AEs) related to product devices used during tibia intramedullary nailing (IMN) procedures. There was a total of 1,799 reports pertaining to tibial intramedullary nailing from 1996 to 2020. Causes included infection (451), nonunion (380), intraoperative issue (343), painful hardware (234), implant fracture (195), other (68), loosening (35), surgeon error (24), packing problem (24), patient injury (12), expiration (12), contamination (11) and allergic reaction (10). The total number of events increased in 2016 and 2018, which was attributed to 510k approval for Stryker. Of the Aes, 1,400 resulted in an injury to the patient. In total, 78% occurred in the post-operative period, and 68% required additional surgery. Most incidents related to tibia IMNs result in injury and require additional surgery. When new products are released, AEs occur quickly and in bulk. (Journal of Surgical Orthopaedic Advances 31(4):237-241, 2022).
