Investigation into the factors affecting bearing thickness when performing rotating-platform posterior-stabilized total knee arthroplasty
Rotating-platform posterior-stabilized total knee arthroplasty (PS-TKA) has become a commonly used procedure. It has the potential risk of causing mobile-bearing spinout. In our study, we investigated the factors affecting the bearing thickness when performing rotating-platform PS-TKA. (Source: The Knee)

Tranexamic acid is safe with respect to the risk of deep venous thrombosis in patients with hemophilic arthritis undergoing total knee arthroplasty without chemoprophylaxis: A prospective study
Pharmacologic thromboprophylaxis is controversial for hemophiliacs who undergo total joint replacements. The purpose of this study was to assess the safety of tranexamic acid (TXA) utilization with respect to the incidence of deep venous thrombosis (DVT) in hemophiliacs undergoing total knee arthroplasty (TKA).

Prognostic factors of knee pain and function 12 months after total knee arthroplasty: A prospective cohort study of 798 patients
Approximately 20% of patients undergoing total knee arthroplasty (TKA) do not experience long-term improvements. Our aim was to identify prognostic factors of knee pain and function 12 months after TKA. (Source: The Knee)

Relationship between medial meniscus extrusion and damage to medial stabilizers: Should extrusion be considered significant only when more than 3 mm?
This study was conducted with patients with anterior and medial extrusion of the medial meniscus (MM-AE, MM-ME) to investigate the relationship of the amount of extrusion with damage to the meniscus, meniscofemoral ligament (MFL), meniscotibial ligament (MTL), presence of effusion, osteoarthritis (OA) grade and other medial stablizers. A cut-off value for significant MM-ME was also suggested. (Source: The Knee)

Long-term results of per-operative knee arthroscopy in confirming suitability for unicompartmental arthroplasty
Patient selection is key to the success of medial unicondylar knee arthroplasty (UKA). Progression of arthritis is the most common indication for revision surgery. Per-operative arthroscopy is a means of directly assessing the integrity of the lateral compartment. The aim of the study is to assess the long-term survivorship of UKA performed when per-operative arthroscopy is used as a final means of deciding whether to proceed with UKA. (Source: The Knee)

Design and evaluation of a 3D printed mechanical balancer for soft tissue balancing in total knee replacement
Soft tissue balancing is an important step in a total knee procedure, carried out manually, or using an indicator. The purpose of this study was to evaluate our design of 3D printed Balancer, and demonstrate how it could be used at surgery. (Source: The Knee)

Dynamic CT scanning of the knee: Combining weight bearing with real-time motion acquisition
Radiological imaging has an important role in the assessment of lower limb musculoskeletal conditions and several factors should be considered when doing such assessments. Firstly, images acquired in a supine position are missing important information about the effect that load has on the lower limb joints, and they do not sufficiently represent the kinematics during normal weight-bearing activities [1,2]; consequently, muscle activation should also be considered; thirdly, 3D images of the structures may provide more diagnostic information compared to 2D projections; lastly, dynamic acquisitions may provide additional info...

High prevalence of associated intra-articular injuries with increasing time period from anterior cruciate ligament injury to reconstruction, even in apparent copers
The objectives were to investigate the clinical characteristics of copers and non-copers that have sustained an anterior cruciate ligament (ACL) injury, and to examine and compare the intra-articular pathologies in delayed ACL reconstruction (ACLR) in copers and noncopers. (Source: The Knee)

Patellofemoral pain syndrome assessed by Lysholm score, radiological and biorheometric measurements
Patellofemoral disorders are defined by pain, dysfunction, imbalance, inflammation, or instability in some components of the knee extension function [1], and are called anterior knee pain syndrome or patellofemoral pain syndrome (PFPS). This syndrome is possible to diagnose by a clinical [2,3] or radiological [4,5] assessment. However, clinical experience suggests that the results of imaging have limited relation to clinical signs [6], tests often do not correlate with the severity of clinical signs [7] and there is an unclear PFPS classification scheme [8].

Personalised opening wedge high tibial osteotomy with patient-specific plates and instrumentation accurately controls coronal correction and posterior slope: Results from a prospective first case series
Patient specific devices represent a promising tool to improve accuracy and simplify high tibial osteotomy (HTO) procedures. The current study aims to assess accuracy of the correction of alignment and posterior tibial slope (PTS), and provide patient reported outcomes (PROMs) of a new personalised cutting guide and fixation plate (TOKA) system for HTO in patients with medial osteoarthritis (OA) and varus knee.

Isolated medial patellofemoral reconstruction outcomes: A systematic review and meta-analysis
Treatment of patellar instability remains up for debate, and a combination of tibial tubercle osteotomy and medial patellofemoral ligament reconstruction (MPFLr) of the medial patellofemoral ligament (MPFL) has become the mainstay treatment for recurrent lateral patellar dislocation. Due to limited small studies, there remains a variety of surgical techniques still being practiced. The use of MPFL reconstruction, in isolation, has demonstrated promise. (Source: The Knee)

Reflections from retirement
I was Editor-in-Chief of The Knee from 2005 to 2012. I retired from clinical practice 7 years ago. When I became Editor, submissions to the journal were on typed A4 paper with printed photographs. Three copies were required of each submission, two went to the peer reviewers and one was kept in my office at home. The job began with receiving six boxes of submissions from the previous editor, John Newman. By the end of 2006 I had been sent 21 boxes in total. Some submissions had yet to be peer-reviewed, many were out to reviewers, and some were awaiting the editor ’s decision. (Source: The Knee)
