Article Abstract
We performed a prospective randomized controlled study to determine whether drainage increased the degree of anemia after primary cementless total hip arthroplasty. After implanting the components, we randomly divided 40 patients (40 hips) into a group who had drains (20 patients, 20 hips) and a group without drains (20 patients, 20 hips). There were no differences in the mean preoperative hemoglobin or hematocrit values, length of skin incision, operative time, intraoperative blood loss, or the donated and transfused volumes of autologous blood between the two groups. There were also no differences in decreased hemoglobin or hematocrit values 3 days postoperatively compared with preoperative values (hemoglobin, 0.7 g/dL versus 0.7 g/dL; hematocrit, 2.2% versus 2.4%). Drainage did not increase the degree of postoperative anemia after cementless total hip arthroplasty.

Patient-Reported Outcomes in Robotic-Assisted vs Manual Cementless Total Knee Arthroplasty.
Arthroplast Today
December 2024
Department of Orthopaedic Surgery, University of Louisville, Louisville, KY, USA.
Background: Robotic-assisted total knee arthroplasty (RA-TKA) was introduced to provide surgeons with virtual preoperative planning and intraoperative information to achieve the desired surgical goals in an effort to improve patient outcomes. The purpose of this study was to compare clinical outcomes and patient-reported outcome measures following primary TKA using RA-TKA vs manual instrumentation.
Methods: This was a retrospective cohort review study comparing 393 primary RA-TKAs vs 312 manual TKAs at a minimum 2-year follow-up.

Background: Total knee arthroplasty (TKA) is one of the most common orthopaedic procedures and the number of patients which undergo TKA will continue to rise in the coming years. Consecutively, the number of necessary revision surgeries will increase. One of the main reasons for revision surgery is aseptic loosening because of a so-called stress-shielding effect.

•The success of cementless fixation in TJA depends on a multitude of factors including biological, mechanical, implant, surgical, and material properties.•Biologic fixation has become the primary mode of fixation for the majority of primary total hip arthroplasty (THA) surgeries done today in the United States (US) due to its low complication rate and superior longevity compared to cemented fixation.•Cementless fixation has yet to gain wider acceptance in total knee arthroplasty (TKA) and hip hemiarthroplasty due to several factors including host bone quality, implant design, and surgical technique.

Adverse Outcomes After Cemented and Cementless Primary Elective Total Hip Arthroplasty in 60,064 Matched Patients: A Study of Data From the Swedish Arthroplasty Register.

Department of Orthopaedics, Institute of Clinical Sciences, University of Gothenburg, Gothenburg, Sweden.
Introduction: The choice between cemented and cementless fixation in primary elective total hip arthroplasty (THA) remains a subject of ongoing debate. However, comparisons between the two are subject to limited adjustments for patient characteristics, diagnoses, and surgical factors, as well as by limited outcome time endpoints. Our study aimed to compare the effect of femoral fixation on safety and implant survival outcomes in matched patients.
