Clinical usefulness and safety in the early phase after a newly designed rotating-platform total knee arthroplasty: A prospective multicentre cohort study with a 2-year follow up
Total knee arthroplasty (TKA) successfully treats osteoarthritis, and various designed prostheses have been demonstrated to have comparable longevities [1]. Posterior-stabilised (PS) TKA, which is used worldwide, is designed with post-cam to stabilise the knee joint and has shown good clinical results [2]. (Source: The Knee)

Postoperative bleeding adversely affects total knee arthroplasty outcomes in hemophilia
Hemophilia is a group of bleeding disorders that lead to recurrent hemarthroses of the knee joints and impaired function. Blood breakdown products such as hemosiderin cause synovial hypertrophy, perivascular lymphocyte and plasma cell infiltration, and inhibition of proteoglycan synthesis and matrix dissolution of the joint cartilage [1 –3]. In addition, the ongoing process of joint damage often results in early joint degeneration. (Source: The Knee)

Platelet-rich plasma use for hip and knee osteoarthritis in the United States
Hip and knee osteoarthritis (OA) are rising in prevalence and increasingly affecting younger patients. There is a rising demand for therapeutics to address its growing disease burden. Platelet-rich plasma (PRP) therapy has been used to treat various musculoskeletal conditions, but its role in OA treatment is not well understood. Even still, there is significant interest in this biologic for treatment of OA. The purpose of this study was to determine the PRP utilization trends in the United States for hip and knee OA.

The effectiveness of internal fixation in the management of acute chondral fractures. A systematic review
Chondral and osteochondral defects are common injuries in orthopedics and can cause patients to suffer from pain, functional impairment, and poor quality of life (QoL) [1 –3]. Chondral defects can be a particularly challenging clinical presentation and can predispose patients to developing degenerative joint disease. This can be especially debilitating for active adults [3–5]. (Source: The Knee)

The natural history of radiolucencies following cemented unicompartmental knee arthroplasty at 7 years
Radiolucent lines (RLLs) following unicompartmental knee arthroplasty (UKA) can be concerning as aseptic loosening remains a cause of failure in UKA. The aim of our study was to report on the history of RLLs surrounding the components in a cemented medial compartment fixed-bearing UKA as well as the long-term functional outcomes in this group of patients.

Knee arthroplasty utilization trends from 2010 to 2019
Interest in partial knee arthroplasty procedures including unicompartmental arthroplasty (UKA), patellofemoral arthroplasty (PFA), and bicompartmental knee arthroplasty (BKA) has increased due to their bone and ligament preservation compared to total knee arthroplasty (TKA). Implant designs, changing thoughts on appropriate indications for partial knee arthroplasty, and availability of navigation also impacted the field over the last decade. The aims of this study were to evaluate trends over the last decade in utilization of 1) partial and total knee arthroplasty; and 2) computer-assistance in knee arthroplasty. (Source: The Knee)

Painful total knee arthroplasty: Infrapatellar branch of the saphenous nerve selective denervation. A case series
Introduction: Total knee arthroplasty (TKA) is a reliable and widespread solution for knee osteoarthritis treatment, but about 20% of the patients complains of persisting pain. Neuroma formation in the IPBSN (infrapatellar branch of the saphenous nerve) is an undervalued cause of persistent anterior pain after TKA. The aim of this study was to evaluate the effectiveness of the selective neuroma denervation on patients satisfaction and pain improvement.Matherial and methods: Between 2014 and 2020, we evaluated 13 patients suffering from persistent anterior knee pain and numbness after TKA who underwent a surgical neurectomy...

How does asymmetric tibial insert affect tibiofemoral kinematics and contact stresses in total knee Arthroplasty?
Asymmetric tibial insert design is expected to restore normal knee kinematics better than symmetric design. A tri-condylar implant has asymmetric and symmetric tibial inserts with a ball-and-socket joint to replace the post-cam mechanism. The purpose of this study was to compare the knee kinematics of the two designs and to measure tibiofemoral contact stresses, including that of the ball-and-socket joint. (Source: The Knee)

A high physical activity level after total knee arthroplasty does not increase the risk of revision surgery during the first twelve years: A systematic review with meta-analysis and GRADE
High physical activity (HPA) levels after total knee arthroplasty (TKA) might be related to increased wear and subsequent aseptic loosening, negatively affecting TKA survival. This systematic review studied the association between activity levels and risk of revision surgery at medium (3 –10 years) and long term (>10 years) follow up in patients with TKA.

Development of a score map to guide interpretation of WOMAC Pain scores prior to knee arthroplasty
Scores from patient reported outcome measures (PROMs) are challenging to interpret for both clinicians and patients. PROMs obtained prior to knee arthroplasty (KA) could be used to inform important decisions related to KA made by both patients and clinicians. The purpose of this study was to develop a “score map” to allow for efficient and meaningful use of PROMs scores for patients considering KA. (Source: The Knee)
