A systematic review of outcomes of high tibial osteotomy for the valgus knee
The knee joint is the most common site of osteoarthritis (OA) in adults over the age of 45 in the UK, with a global prevalence of 22.9  % [1,2]. Conservative treatment options for patients with knee OA include lifestyle changes and pharmacological pain management [3]. When conservative treatments cease to be effective at treating the symptoms of OA, surgical treatments are considered. The selection of surgical intervention is depe ndent on the indications of the procedure and specific patient criteria. (Source: The Knee)

Three-stage total knee arthroplasty combined with deformity correction and leg lengthening using Taylor spatial frames and conversion to internal fixation for severe intra- and extra-articular deformities and hypoplasia in a patient with hemophilic knee arthropathy: A case report
Hemophilic arthropathy is a cause of severe knee deformity, because chronic synovitis due to repeated hemarthrosis affects the area of the epiphyseal plates in juvenile cases. Total knee arthroplasty (TKA) is the standard treatment for end-stage knee arthropathy. However, it is difficult to perform one-stage TKA in patients with severe intra- and extra-articular deformities. (Source: The Knee)

Supra tubercular tibial osteotomy and gradual correction with Taylor spatial frame for the management of Torsional malalignment syndrome – surgical technique and outcomes
Surgical management of Torsional Malalignment Syndrome (TMS) traditionally consists of simultaneous correction of both femoral anteversion and external tibial torsion. We hypothesise that a single supra tubercular osteotomy followed by tibial derotation with Taylor Spatial Frame (TSF) is sufficient to provide significant improvement in both appearance and function.

Indications and timing in isolated medial femoral hemiepiphysiodesis for idiopathic genu valgum: A systematic review
Genu valgum is a common condition among children and adolescents [1]. During growth, the mechanical axis of the knee modifies physiologically from varus at birth, to a 3-5 ° valgus at the age of seven [2]. The failure of this process leads to coronal knee deformities and, when these occur, it is essential to determine the underlying causes. Eighty percent of all pathological genu valgum is considered idiopathic [3], which is defined by intermalleolar distance (IMD) g reater than 8 cm [4]. The deformity should be corrected in order to avoid the onset of the symptoms which can lead to knee distress, poor alignment, activit...

Low dose vancomycin-loaded spacers for two-stage revision knee arthroplasty: High success, low toxicity
Two-stage revision arthroplasty is a widely used treatment method for infected knee arthroplasty. Loading high doses of antibiotics to spacer during the first stage is standard practice. However, there are reported systemic side effects attributed to antibiotic-loaded spacers. The aim of our study is to investigate the success rate and systemic toxicity following the first stage revision knee arthroplasty with low-dose vancomycin-loaded spacers. (Source: The Knee)

Supervised versus unsupervised rehabilitation following total knee arthroplasty: A systematic review and meta-analysis
Outcomes after total knee arthroplasty (TKA) are strongly influenced by the adequacy of rehabilitation and the consequent functional recovery. The economic impact of rehabilitation it is not negligible. Inpatient rehabilitation can be 5 to 26 times more expensive than the home-based rehabilitation. This topic is extremely relevant as the COVID-19 pandemic has highlighted the importance of unsupervised rehabilitation in orthopedic surgery. The aim of this review and meta-analysis is to investigate the scientific evidence regarding the comparison between supervised and unsupervised rehabilitation following TKA. (Source: The Knee)

Immunohistochemical analysis of the quadriceps femoris muscle before and after total knee arthroplasty
The number of total knee arthroplasties (TKA) has increased steadily with the aging of the population. This surgical procedure is recognized for its success in pain relief and restoration of knee function. However, decreased quadriceps femoris (QF) muscle strength after TKA is frequently observed but with unknown etiology. Evidence suggests that the location of the operative incision (i.e., surgical access) can influence QF muscle structure and function. The present study aimed to assess the fiber type composition, structure and assembly of the QF's vastus medialis (VM) and vastus lateralis (VL) muscles before and after TK...

Unloader bracing in osteoarthritis of the knee – Is there a direct effect on the damaged cartilage?
Osteoarthritis of the knee represents a common source of pain, leading to disability, loss of knee function and immobility. The development of knee osteoarthritis has been attributed to a multifactorial pathogenesis [1]. Nevertheless, abnormal loading and altered load distribution are considered as key biomechanical factors for the onset and progression of knee osteoarthritis [2,3]. Varus- or valgus alignment of the tibiofemoral joint has been recognized as prearthritic deformity leading to an overload and cartilage wear of the medial or lateral compartment, respectively [1 –4].

Lateral retinacular release in concordance with medial patellofemoral ligament reconstruction in patients with recurrent patellar instability: A computational model
The aim of this study was to develop and validate a finite element (FE) model of the patellofemoral joint to analyze the biomechanics of lateral retinacular release after medial patellofemoral ligament (MPFL) reconstruction in patellar malalignment (increased tibial tubercle –trochlear groove distance (TT-TG)). We hypothesized that lateral retinacular release is not appropriate in patellar instability addressed by MPFL reconstruction due to decreased lateral stability and inappropriate adjustment in patellofemoral contact pressures.

Does pin configuration matter in modified tension band wiring for transverse patellar fracture? A biomechanical study
Modified tension band wiring has been widely used for the treatment of transverse patellar fractures. The optimal position of a Kirschner wire (K-wire) in modified tension band wiring, however, has not yet been determined. The purpose of the present study was to evaluate biomechanically the effect of K-wire position in a modified tension band wiring technique. (Source: The Knee)
