British surgeons and engineers contributed various types of knee prostheses, including hinged, unconstrained, and semiconstrained prostheses, in the development of total knee arthroplasty. Methods of implant fixation, the place of stems, pegs, the use of special instrumentation, and alignment procedures ensure both intrinsic and extrinsic prosthetic stability.

ASA Class Is a Stronger Predictor of Early Revision Risk Following Primary Total Knee Arthroplasty than BMI.
JB JS Open Access
January 2025
School of Medicine, Rural Clinical School, University of Queensland, Toowoomba, Queensland, Australia.
Background: Although there is a known correlation between obesity and revision risk following total knee arthroplasty (TKA), there is an ongoing debate regarding the appropriateness of denying TKA solely based on the body mass index (BMI) of a patient. Our aim was to determine whether a patient's American Society of Anesthesiologists (ASA) class predicts their risks of early all-cause revision and revision for periprosthetic joint infection (PJI) following primary TKA, independent of their BMI.
Methods: Data from the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) were obtained regarding all patients who underwent primary TKA for osteoarthritis in Australia from January 1, 2015, to December 31, 2022.
Hemostatic effect of oxidized regenerated cellulose vs. topical tranexamic acid in total knee arthroplasty-a prospective randomized controlled trial.
Front Surg
January 2025
Department of Knee Joint Surgery, Xi'an Honghui Hospital, Xi'an Jiaotong University, Xi'an, Shaanxi, China.
Aims: This study compared the hemostatic effects and complications of oxidized regenerated cellulose (ORC) and topical TXA in total knee arthroplasty (TKA), thus providing a reference for the use of ORC as an alternative hemostatic agent to TXA in TKA.
Methods: A total of 105 patients were included in this study and randomized into blank control, ORC, and TXA groups. The primary outcomes were total blood loss, hemoglobin drop (Hb drop), transfusion rates, and incidence of thrombosis.
Elective Treatment Strategy for Knee Prosthetic Joint Infection.
Cureus
December 2024
Orthopaedics, Saitama Medical Center, Saitama, JPN.
Introduction: Prosthetic joint infection (PJI) is a complication, rarely encountered in daily clinical practice, but its treatment is frequently unsuccessful. In this report, we describe the treatment strategy used at our hospital, which has provided stable therapeutic results.
Methods: We conducted a retrospective analysis of infections following knee arthroplasty at our hospital between April 2005 and December 2022.
In functionally aligned total knee arthroplasty, femoral component rotation follows the transepicondylar axis to achieve flexion balance.
Knee Surg Sports Traumatol Arthrosc
January 2025
Clinical Research Department, Sydney Knee Specialists, Kogarah, New South Wales, Australia.
Purpose: In functionally aligned (FA) total knee arthroplasty (TKA), femoral component rotation (FCR) is personalised to optimise flexion gap balance. As axial malalignment has been attributed to patellofemoral complications, this study assessed FA FCR in relation to the surgical transepicondylar axis (TEA) and early implant survivorship.
Methods: We analysed 446 robotic-assisted primary TKAs in 393 patients using FA with preresection gap balancing.
Sound levels in the operating theatre resulting from hammering during cementless total hip arthroplasty.
J Orthop Sci
January 2025
Department of Medicine for Orthopaedics and Motor Organ, Juntendo University Graduate School of Medicine, 2-1-1, Hongo, Bunkyo-ku, Tokyo 113-0033, Japan; Department of Orthopaedics, Faculty of Medicine, Juntendo University, 2-1-1, Hongo, Bunkyo-ku, Tokyo 113-0033, Japan.
Background: Although hearing loss in orthopaedic surgeons from exposure to hammering sounds have been previously reported, there are no reports on the noise environment during total hip arthroplasty (THA) in Japan. The aim of this study was to investigate the sound level generated by cementless THA in Japan, and to discuss the broader sound environment within this space.
Methods: 94 cementless THAs (94 patients with informed consent) performed by four surgeons were included.
