The anteroposterior distance between the posterior edge of the medial tibial condyle and the posterior edge of the fibular head in the lateral view can be a reference in determining the axis perpendicular to the tibial anteroposterior axis
This study investigated whether the posterior edge of the medial/lateral tibial condyle (PEMTC/PELTC) and the posterior edge of the fibular head (PEFH) in a lateral view could be a reference for determining the accurate tibial lateral view. (Source: The Knee)

To resurface or not to resurface? Investigating the impact of patellar resurfacing on anterior knee pain in rheumatoid arthritis patients undergoing total knee replacement
Routine patellar resurfacing is a controversial issue in total knee replacement (TKR), especially for rheumatoid arthritis (RA). Anterior knee pain (AKP) is a common complaint after TKR that may be related to patellofemoral joint condition. The aim of this study was to investigate the prevalence and factors associated with AKP after TKR for RA compared between non-resurfaced patella (NRP) and resurfaced patella (RP). (Source: The Knee)

Posterior tibial slope correlated with metaphyseal inclination more than metaphyseal height
Excessive posterior tibial slope (PTS) is an independent risk factor for anterior cruciate ligament reconstruction (ACLR) failure, but it remains unclear how PTS relates to other proximal tibial morphologic parameters. The purpose of this study was to analyse sagittal tibial metaphysis morphology, and to calculate the correlation coefficients of PTS with anatomical features. (Source: The Knee)

Unicompartmental knee arthroplasty revised to total knee arthroplasty versus primary total knee arthroplasty: A meta-analysis of matched studies
Unicompartmental knee arthroplasty (UKA) offers a less invasive alternative to total knee arthroplasty (TKA), but is accompanied by a high revision risk. The aim of our study was to perform a meta-analysis comparing outcomes of UKA revised to TKA versus primary TKA, to assess if UKA is an effective treatment option, despite its potential need for revision.

The development of machine learning algorithms that can predict patients satisfaction using baseline characteristics, and preoperative and operative factors of total knee arthroplasty
Patient satisfaction following primary total knee arthroplasty (TKA) is a crucial part to evaluate the success of the procedure. The purpose of this study was to develop to predict patient satisfaction following TKA. (Source: The Knee)

Clinical and radiographic characterization of three-dimensional gait profiles of patients with knee osteoarthritis
Our findings suggest that most clinical and radiographic characteristics commonly measured in clinical practice did not differ significantly among knee osteoarthritis patients with the four different gait profiles. The only exception was a higher BMI noted in those with gait profile 4; however, it remains unclear whether it can cause varus thrust or rotation rigidity. The incorporation of three-dimensional motion analysis to identify gait profiles provided clinical insights beyond the limitations of traditional clinical assessments. (Source: The Knee)

Medium-term outcome of medial patellofemoral ligament reconstruction using synthetic graft
Recurrent patella instability is a common and debilitating condition which affects mainly adolescents and young adults. Medial patellofemoral ligament (MPFL) reconstruction is the most popular surgical treatment for recurrent patella instability. The most common graft choice in the literature is ipsilateral hamstring tendon (gracilis or semitendinosis) but the complication rate remains high (11 –26%). Conversely, there are very few papers on the use of modern, synthetic grafts. (Source: The Knee)

Incidence and risk factors for lateral hinge fractures in medial opening wedge high tibial osteotomy and medial opening wedge distal tibial tuberosity osteotomy
The aims of this study were (1) to compare the incidence of lateral hinge fractures (LHFs) in medial opening-wedge high tibial osteotomy (OWHTO) and medial opening-wedge distal tibial tuberosity osteotomy (DTO), and (2) to investigate the risk factors for LHFs. The incidence of LHFs was hypothesized to be higher in the DTO group than the OWHTO group. The DTO procedure is also a risk factor for LHFs. (Source: The Knee)

Referencing the center of the femoral head during robotic or computer-navigated primary total knee arthroplasty results in less femoral component flexion than the traditional intramedullary axis
During robotic and computer-navigated primary total knee arthroplasty (TKA), the center of the femoral head is utilized as the proximal reference point for femoral component position rather than the intramedullary axis. We sought to analyze the effect on femoral component flexion –extension position between these two reference points. (Source: The Knee)

Development of an educational three-dimensional anatomical structure replication tool and its application to medial open-wedge high tibial osteotomy
With the standardization of surgical techniques and continuous development of plate fixators, medial open-wedge high tibial osteotomy (OWHTO) has become an option for the treatment of medial knee osteoarthritis. However, it is also associated with several complications. To reduce the risk of these complications, it is essential for surgeons to accurately understand the three-dimensional (3D) anatomical structures, including the surroundings of the surgical field. Gross dissection using a cadaver provides a large surgical field and is the best learning method for studying anatomical structures in three dimensions; however, ...
