Current clinical practice of knee osteotomy in the Netherlands
Realignment osteotomies is gaining popularity amongst Dutch orthopaedic surgeons. Exact numbers and used standards in clinical practice concerning osteotomies are unknown due to the absence of a national registry. The aim of this study was to investigate the national statistics of performed osteotomies, utilized clinical workups, surgical techniques, and post-operative rehabilitation standards in the Netherlands.

Letter to the editor on “Clinical outcomes of medial patellofemoral ligament reconstruction using FiberTape and knotless SwiveLock anchors”
We read with great interest of the article ‘‘Clinical outcomes of medial patellofemoral ligament reconstruction using FiberTape and knotless SwiveLock anchors” by Sasaki et al. [1]. The authors investigated the clinical outcomes of medial patellofemoral ligament (MPFL) reconstruction using polyester high-strength suture tape with knotl ess anchors [1]. This interesting and meaningful study demonstrated that reconstruction of the MPFL with suture tape augmentation maybe a valuable alternative for restoration of patella stability, without requiring harvesting autologous tendon grafts.

Influence of articular step-off on contact mechanics in fractures of the posterolateral-central tibial plateau - a biomechanical study
The posterior quadrants of the tibial plateau are frequently involved in OTA type C tibial plateau fractures. The biomechanical influence of a residual articular step-off of the posterolateral-central (PLC) segment, which is difficult to visualize intraoperatively, remains unclear.Therefore, aim of this study was to investigate the contact area and stress of the tibial plateau in cases of different articular step-offs of the PLC segment.

Coronal alignment classes after robotic-assisted total knee arthroplasty are not associated with variation in patient-reported outcome measurements: A single-center cohort study
The aims of this study were (1) to use three-dimensional computed tomography (3DCT) measurements to determine whether patients undergoing imageless robotic-assisted total knee arthroplasty (RA-TKA) develop a variety of postoperative distal femoral mechanical angle (FMA), proximal tibial mechanical angle (TMA), and hip-knee-ankle angle (HKA) phenotypes as described by Hirschmann et al, and (2) to compare postoperative patient-reported outcome measurements (PROMs) between these phenotypes.

Disease burden of and expectations from surgery in patients prior to total knee arthroplasty: Results of the prospective FInGK study
Osteoarthritis (OA) is one of developed countries ’ ten most disabling diseases [1]. It is characterized by the degeneration of cartilage and surrounding joint structures and often leads to pain, reduced function, and, consequently, diminished quality of life (QoL) [2]. As a large weight-bearing joint, the knee is most commonly affected [3]. Mana gement of knee OA traditionally involves a combination of non-pharmacological and pharmacological interventions [4,5]. However, for individuals with end-stage knee OA no longer responding to non-surgical interventions, total knee arthroplasty (TKA) is recommended [6]. (Source: The Knee)

Temporal trends in the rate of complications and prolonged length of stay relative to body mass index in patients undergoing total knee arthroplasty from 2012 to 2020
Elevated body mass index (BMI) is a risk factor for complications following total knee arthroplasty (TKA). Thus, we believe it is important to constantly re-evaluate the relationship between BMI and complication risk following TKA. (Source: The Knee)

Extensor mechanism injury, infection, and an extended time between trauma and surgical approach are related to the need for total knee arthroplasty removal after traumatic dehiscence
This study aims to report the clinical outcomes and complications of a case series due to traumatic dehiscence after total knee arthroplasty (TKA) and establish possible criteria for prognosis for maintaining the implant. (Source: The Knee)

High tibiofemoral contact and muscle forces during gait are associated with radiographic knee OA progression over 3 years
The objective of this study was to investigate differences in tibiofemoral joint contact forces between individuals with moderate medial OA who exhibit radiographic knee OA progression within 3 years versus those who do not, and to understand the relationship between model-predicted contact forces and net external moments for this population.

Limb alignment changes with knee flexion: A study based on CAS data
Frontal alignment of the lower limb is of interest in total knee arthroplasty because it is the main parameter that can be modified during surgery to lower resulting stresses on prosthetic knee by reducing the adduction moment. The mechanical alignment technique for TKA aims to correct the limb deformity to neutral as it is believed to have biomechanical advantages that could improve implants lifespan by reducing the knee adduction moment (generated by the ground reaction force and its lever arm at the knee joint center) and consequently the medial compartment load [1,2].

A classification system of joint-salvage tumor resection in osteosarcoma of the knee: A retrospective cohort study
Joint-preserving and intra-articular tumor resection are two options for juxta-articular osteosarcoma of the knee [1,2]. While intra-articular resection offers a safe surgical margin at the joint end, subsequent endoprosthetic reconstruction presents complications resulting in survival rate of endoprosthesis ranging from 50 to 70 % [3–6]. Meanwhile, these procedures not only excise the joint end of the affected limb, but also sacrifice the other joint side of the knee, which disturbs skeletal growth and presents limb discrepancy in children [7,8].

Biomechanical analysis of different fixation methods for Rorabeck II supracondylar femoral fractures after total knee arthroplasty
Locking plate (LP) and retrograde intramedullary nailing (RIMN) are widely used to fix Rorabeck II supracondylar femoral fractures after total knee arthroplasty (TKA). The biomechanical properties of the implant used for treatment influence its longevity. Therefore, we aimed to evaluate the biomechanical stability of different fixations using finite element analysis. (Source: The Knee)
