RESUMO
BACKGROUND: Dexamethasone (DEX) has demonstrated promise with respect to decreasing postoperative thromboembolic complications following total joint arthroplasty (TJA). Therefore, the aim of this study was to investigate the effects of perioperative intravenous DEX on rates of pulmonary embolism (PE) and deep vein thrombosis (DVT) after primary TJA in patients who have a history of venous thromboembolism (VTE). METHODS: Patients who have a history of VTE who underwent primary elective TJA from 2015 to 2021 were identified using a commercial health care database. Patients were divided based on receipt of perioperative intravenous DEX [DEX(+) versus DEX(-)] on the day of index TJA. Patient demographics and hospital factors were collected. The 90-day risk of postoperative complications, readmission, and in-hospital mortality were compared. RESULTS: Overall, 70,147 patients who had a history of VTE underwent TJA, of which 40,607 (57.89%) received DEX and 29,540 (42.11%) did not. The DEX(+) patients were younger (67 ± 9.8 versus 68 ± 9.9 years, P < .001) and had a significantly shorter length of stay compared to the DEX(-) patients (1.8 ± 1.6 versus 2.2 ± 1.8 days, P < .001). The DEX(+) patients demonstrated lower rates of PE (1.37 versus 1.75%, P < .001) and DVT (2.37 versus 3.01%, P < .001) compared to DEX(-) patients. The DEX(+) patients experienced a lower risk of PE (adjusted odds ratio: 0.78, 95% confidence interval: 0.66 to 0.93, P = .006) and DVT (adjusted odds ratio: 0.84, 95% confidence interval: 0.74 to 0.95, P = .006) compared to DEX(-) patients. The DEX(+) patients demonstrated no differences in the odds of surgical site infection, periprosthetic joint infection, or sepsis compared to the DEX(-) patients (P > .05). CONCLUSIONS: The administration of DEX was associated with a decreased risk of PE and DVT in patients who have a history of VTE who underwent TJA. These data warrant further study investigating the postoperative benefits of perioperative DEX administration for high-risk patients undergoing TJA. LEVEL OF EVIDENCE: Level III.
RESUMO
BACKGROUND: Extensor mechanism disruption is a challenging complication following total knee arthroplasty. The purpose of this study was to compare outcomes between patients who received mesh versus allograft extensor mechanism reconstruction. METHODS: All patients who underwent extensor mechanism reconstruction at a single institution were screened. Demographic and surgical variables were recorded, including technique (ie, synthetic mesh versus allograft reconstruction). Patients were assessed for preoperative and postoperative extensor lag, revision, and duration of follow-up. Analyses, including Kaplan-Meier survivorships, were performed to compare mesh to allograft reconstruction. In total, 50 extensor mechanism reconstructions (30 mesh and 20 allograft) were conducted between January 1st, 2001, and December 31st, 2022. RESULTS: There were no differences between the cohorts with respect to revision (26.7 [8 of 30] versus 35.0% [7 of 20], P = .680) or failure defined as above knee amputation or fusion (6.7 [2 of 30] versus 5.0% [1 of 20], P = .808). There were also no differences in time to reoperation (average 27 months [range, 6.7 to 58.8] versus 29 months [range, 1.2 to 84.9], P = .910) or in postoperative extensor lag among patients who did not undergo a reoperation (13 [0 to 50] versus 11° [0 to 30], P = .921). The estimated 5-year Kaplan-Meier survival with extensor mechanism revision as the endpoint was similar between the 2 groups (52.1, 95% confidence interval [CI] = 25.4 to 73.3 versus 55.0%, 95% CI = 23.0 to 78.4%, P = .990). CONCLUSIONS: The purpose of this study was to present the findings of a large cohort of patients who required extensor mechanism reconstruction. Regardless of the reconstruction type, the 5-year outcomes of patients requiring extensor mechanism reconstruction are suboptimal.

BACKGROUND: Same-day total hip arthroplasty (THA) and total knee arthroplasty (TKA) continue to gain popularity in the United States. The present study sought to quantify recent same-day outpatient trends taking into consideration the COVID-19 pandemic as well as the removal of these procedures from the Medicare inpatient only (IPO) list. METHODS: Patients undergoing primary elective TKA and THA were identified using the Nationwide Ambulatory Surgery Sample and the National Inpatient Sample from January 1, 2016, to December 31, 2020. The same-day cohort included Nationwide Ambulatory Surgery Sample and National Inpatient Sample patients with a length of stay = 0 days. The inpatient cohort included patients with length of stay ≥1 day. National estimates were extrapolated using weight functions. RESULTS: From January 2016 to December 2020, the proportion of same-day TKA increased from 1.2 (719) to 62.4% (31,293) and the proportion of same-day THA increased from 2.0 (599) to 54.5% (18,252). Following removal from the Medicare IPO list, same-day TKAs increased from 3.2% (1,895) in December 2017 to 13.8% (9,269) in January 2018, and same-day THAs increased from 10.7% (4,295) in December 2019 to 22.5% (8,708) in January 2020. Between February and March 2020, same-day TKAs increased from 42.4 (26,148) to 44.4% (16,972) and same-day THAs increased from 28.5 (10,729) to 30.2% (7,409). CONCLUSIONS: The proportion of same-day TKA and THA dramatically increased following removal from the Medicare IPO list and in response to the COVID-19 pandemic. By December 2020, same-day TKA and THA accounted for >50% of all cases performed in the United States.

BACKGROUND: This study sought to determine the total amount of time committed to planned and unplanned episodes of care related to primary, unilateral total joint arthroplasty (TJA), relative to a growth in outpatient TJA. METHODS: All primary, unilateral TJA procedures performed over a 7-year period by a single surgeon at a single institution were retrospectively reviewed. Time dedicated to planned work was calculated over each episode of care, from surgery scheduling to 90 days postoperatively. All telephone inquiries and readmissions involving the surgeon's direct input, over the episode of care, constituted time dedicated to unplanned work. RESULTS: Between 2012 and 2018, as the proportion of outpatient TJAs increased, the average planned episode-of-care time per patient decreased from 412 minutes to 361 minutes. Despite a 108% increase in the total number of outpatient TJAs between 2017 and 2018 (51/432 (11.8%) to 106/555 (19.1%); P = .002), neither the average number of unplanned telephone inquiries (4.6 ± 3.8 vs 4.2 ± 3.7; P = .124), nor the mean time per patient required to respond to calls (23.1 ± 19.4 vs 21.2 ± 18 minutes, P = .135) differed. Between 2017 and 2018, the average total episode-of-care time per patient decreased from 403 minutes (376 planned + 27 unplanned) to 387 minutes (361 planned + 26 unplanned). CONCLUSION: Despite an increase in outpatient TJA, the average time required for planned and unplanned patient care remained relatively constant. The growth of outpatient TJA nationally should not trigger a change in Centers for Medicare and Medicaid Services benchmarks.
