Metaphyseal fixation has promising early results in providing component stability and fixation in revision total knee arthroplasty (TKA). However, there are limited studies on midterm results of metaphyseal sleeves. We analyzed complications, rerevisions, and survivorship free of revision for aseptic loosening of metaphyseal sleeves in revision TKA. ⋯ Metaphyseal sleeve fixation to enhance component stability during revision TKA has a 5-year survivorship free of revision for aseptic loosening of 96% and 99.5% in femoral and tibial sleeves, respectively. Both cemented and cementless sleeve fixation provides reliable durability at intermediate follow-up.

Review Meta Analysis
The Efficacy of Liposomal Bupivacaine Using Periarticular Injection in Total Knee Arthroplasty: A Systematic Review and Meta-Analysis.
Total knee arthroplasty (TKA) is gradually emerging as the treatment of choice for end-stage osteoarthritis. In the past, the method of liposomal bupivacaine by periarticular injection (PAI) showed better effects on pain reduction and opioid consumption after surgery. However, some recent studies have reported that liposomal bupivacaine by PAI did not improve pain control and functional recovery in patients undergoing TKA. Therefore, this meta-analysis was conducted to determine whether liposomal bupivacaine provides better pain relief and functional recovery after TKA. ⋯ Compared with the conventional PAI method, liposomal bupivacaine shows similar pain control and functional recovery after TKA. Considering the cost for pain control, liposomal bupivacaine is not worthy of being recommended as a long-acting alternative analgesic agent using the PAI method.

Changes in reimbursement for total hip and knee arthroplasties (THA and TKA) have placed increased financial burden of early readmission on hospitals and surgeons. Our purpose was to characterize factors of 30-day readmission for surgical complications after THA and TKA at a single, high-volume orthopedic specialty hospital. ⋯ Risk factors for 30-day readmission for surgical complications included short LOS, discharge destination, increased procedure/tourniquet time, potent anticoagulation use, and preoperative diagnosis of depression. A focus on risk factor modification and improved risk stratification models are necessary to optimize patient care using readmission rates as a quality benchmark.

The blood-conserving effect of intravenous (IV) tranexamic acid (TXA) is well-documented for total hip arthroplasty (THA) and total knee arthroplasty (TKA). However, the risk of thromboembolic (TE) events after routine use of TXA is unclear and the safety profile is debated. This retrospective study investigates patient characteristics, occurrences, and predictors of TE events after routine administration of IV TXA in THA and TKA. ⋯ The findings suggest that routine use of IV TXA for TKA and THA as safe with low occurrence of TE events, although a large prospective trial should confirm this.

Venous thromboembolism (VTE) is a potentially preventable and costly complication after total hip arthroplasty (THA) and total knee arthroplasty (TKA). The in-hospital incidence and economic burden of VTE following total joint arthroplasty (TJA) in the United States is unknown. The aim of this study was to examine this issue. ⋯ Based on the analysis of the Nationwide Inpatient Sample database, the rate of in-hospital DVT following TJA appears to have declined over the last decade while the incidence of PE has remained constant. This may indicate that the current recommendations by the American Academy of Orthopaedic Surgeons for VTE prophylaxis are adequate for preventing DVT without increasing the rate of PE or that institutional screening and reporting of DVT has been reduced because DVTs became a "never" event.
