The objective of this study is to compare rural patients undergoing primary total joint arthroplasty (TJA) at rural hospitals with those undergoing primary TJA at urban hospitals with regards to demographics, comorbidities, and complications and to determine the preferred location of care for rural patients. Data from the Healthcare Cost and Utilization Project National Inpatient Sample between 2016 and 2018 were analyzed. Demographics, comorbidities, inpatient complications, hospital length of stay, inpatient mortality, and discharge disposition were compared between rural patients who underwent TJA at rural hospitals and urban hospitals. Rural patients undergoing primary TJA in rural hospitals were more likely to be women, to be treated in the South, to have Medicaid payer status, to have dementia, diabetes mellitus, lung disease, and postoperative pulmonary complications, and to have a longer hospital length of stay. Those patients were also less likely to have baseline obesity, heart disease, kidney disease, liver disease, cancer, postoperative infection, and cardiovascular complications, and were less likely to be discharged home. Rural patients undergoing primary TJA tend to pursue surgery in their rural hospital when their comorbidity profile is manageable. These patients get their surgery performed in an urban setting when they have the means for travel and cost, and when their comorbidity profile is more complicated, requiring more specialized care, Rural patients are choosing to undergo their primary TJA in urban hospitals as opposed to their local rural hospitals.

This study evaluated these tests to determine their diagnostic utility in suspected septic arthritis. A retrospective chart review was performed on patients admitted to an urban hospital who underwent arthrocentesis. The authors evaluated the jWBC, %PMN, ESR, and CRP with receiver operating characteristic (ROC) curve analyses. Two hundred sixty-five patients met inclusion criteria. Sixty-three had a culture-positive aspirate. ROC curve analysis resulted in an area under the curve (AUC) of 0.80 for jWBC with cutoff point of 22,563 cells/mm3 and an AUC of 0.71 for %PMN with cutoff point of 90.5%. CRP and ESR had AUC values of 0.62 and 0.61, respectively. The culture-positive cohort had higher elevations in all assessed diagnostic tests. However, AUC data for ESR and CRP showed little diagnostic utility. Additionally, sensitivities and specificities of jWBC and %PMN were too low. Associated cutoff points would result in excessive unnecessary operative intervention. Further studies should incorporate synovial fluid biomarkers into the workup of a suspected septic joint.

Manipulation under anesthesia (MUA) is commonly regarded as the preferred initial treatment of arthrofibrosis following total knee arthroplasty (TKA). There have been no well-controlled studies demonstrating that MUA effectively increases ROM in patients who develop arthrofibrosis after TKA when compared with routine care. The purpose of this study was to determine whether MUA had any advantage over routine care in the treatment of patients who developed arthrofibrosis following TKA. The authors identified patients who underwent primary TKA at the authors' institution between 2010 and 2014 and had flexion ≤ 100 degrees at early follow-up. Knees were grouped based on how the arthrofibrosis was treated: those who underwent MUA and those who received routine care. Knee flexion was captured preoperatively (prior to TKA), at early follow-up (prior to MUA or routine care), and at 1-year follow up. Flexion change from early follow-up to 1 year was calculated. The average flexion at 1-year follow-up was not significantly different between the two groups (106.1 ± 11.7 degrees in the routine care group versus 106.3 ± 12.8 degrees in the MUA group). The MUA group had a greater proportion of patients with flexion gains > 20 degrees at final follow-up when compared with patients who underwent routine care (56% vs. 8%, p < 0.0001). This study demonstrates that patients with decreased ROM at early follow-up after primary TKA can expect greater ROM increase at 1-year follow-up if they undergo MUA compared with patients who undergo routine care.
