Comparative Study
Historical implant or current best standard? Minimum five year follow-up outcomes of cemented Thompson hemiarthroplasties.
UK NICE guidelines recommend abandoning the Thompson hemiarthroplasty (TH) in favour of a 'proven prosthesis' such as the Exeter Trauma Stem. The aim of this study was to assess the hip fracture treatment with the TH. ⋯ The TH remains a reliable and proven implant in appropriate patients (over the age of 80, with low activity levels, low ambulatory status and who maybe cognitively impaired), due to low complication and revision rates. Modern implants may provide better function or longevity, but there is little evidence to support abandoning the TH.

This study investigated the impact of metabolic syndrome (MetS) on perioperative and postoperative complication rates: the results of a cohort of 168 total hip and knee arthroplasties, 63 of normal weight, 105 with obesity without risk factors for metabolic syndrome and 39 with obesity and other factors that classify them with metabolic syndrome. Patients with metabolic syndrome were more likely to have complications than those without metabolic syndrome (P=0.0156). ⋯ The presence of MetS in patients undergoing total joint arthroplasty has a significant impact on surgical complication rates. This cannot be attributed to the BMI component alone, and may help guide efforts of patient optimization prior to total joint arthroplasty.

Understanding the impact of obesity on elective total joint arthroplasty (TJA) remains critical. Perioperative outcomes were reviewed in 316 patients undergoing primary TJA. ⋯ Additionally, PBF of 43.5 was associated with a 2.4× greater likelihood of blood transfusion, PBF of 36.5 with a 1.9× greater likelihood for LOS >3 days, and PBF of 36.0 with a 1.4× greater likelihood for discharge to an extended care facility. PBF may be a more effective measure than BMI to use in screening for perioperative risks and acute outcomes associated with obese total joint patients.

Tranexamic acid (TXA) has been used successfully in primary total knee arthroplasty (TKA) to minimize blood loss and transfusions. The purpose of this study is to determine its efficacy in patients undergoing revision TKA. ⋯ When stratified by type of revision, treatment patients undergoing femoral and tibial component revision had lower transfusion rates than the controls (P=0.03). Given the drawbacks of allogenic blood transfusion, we highly recommend the use of TXA in revision TKA, especially when both components are being revised.

Reimbursement continues to decrease for orthopaedic surgeons specializing in total joint arthroplasty (TJA). Practice information from the Medical Group Management Association (MGMA) Cost Survey and Private practice Compensation Survey and CMS locality reimbursement data was used to develop a practice model for a TJA specialist performing 300 TJA per year (66% knees, 33% hips, 15% revision surgery), evaluating 3000 outpatient visits per year based on, current Medicare reimbursement rates. ⋯ When MGMA practice expense data are applied to the Medicare-only model, the salary level is unsustainable. Further decreases in Medicare Part B reimbursement will only worsen the disparity.
