Effects of sagittal tibial osteotomy on frontal alignment of the knee and patellar height.

Int Orthop 2020 May 9. Epub 2020 May 9.

Orthopaedics Surgery and Sports Medicine Department, FIFA Medical Center of Excellence, Croix Rousse Hospital, Civil Hospices of Lyon, 103 Boulevard de la Croix Rousse, 69004, Lyon, France.

Aim Of The Study: The aim of this study was to evaluate the radiographic effect of sagittal tibial osteotomy (STO), flexion tibial osteotomy (FTO) and deflexion tibial osteotomy (DTO) around the knee. It has been hypothesized that proximal STO modifies patellar height and could cause varus/valgus changes of the anatomical tibial axis: The purpose of the study was to verify this and to analyse these modifications.

Method: Patients underwent proximal STO in our department between 2007 and 2018: overall 28 consecutive patients (19 males, 9 females; 28 knees). Read More

J Hip Preserv Surg 2020 Jan 25;7(1):153-159. Epub 2020 Jan 25.

Centum High School, Busan, South Korea.

Femoral retroversion is an extra-articular cause of cam-type femoroacetabular impingement (FAI) via early engagement with anterior rim. Valgus hip also causes extra-articular FAI by decreasing the range of motion. We present a case of valgus hip accompanied by femoral retroversion, which was refractory to prior arthroscopic femoroplasty. Read More

Subchondral insufficiency fractures of the femoral head: systematic review of diagnosis, treatment and outcomes.

J Hip Preserv Surg 2020 Jan 28;7(1):85-94. Epub 2019 Nov 28.

Department of Orthopaedic Surgery, Cleveland Clinic Foundation, 9500 Euclid Avenue A41, Cleveland, OH 44123, USA.

Subchondral insufficiency fractures of the femoral head (SIFFH) are a cause of femoral head collapse leading to degenerative hip disease. SIFFH is often mistaken for osteonecrosis given similar clinical and radiographic features. These similarities often lead to missed or delayed diagnosis which can often delay or change management.

Neutral alignment resulting from tibial vara and opposite femoral valgus is the main morphologic pattern in healthy middle-aged patients: an exploration of a 3D-CT database.

Knee Surg Sports Traumatol Arthrosc 2020 May 5. Epub 2020 May 5.

Aix Marseille Univ, APHM, CNRS, ISM, Sainte-Marguerite Hospital, Institute for Locomotion, Department of Orthopedics and Traumatology, Marseille, France.

Purpose: Given the goal of achieving optimal correction and alignment after knee arthroplasty or high tibial osteotomy, literature focusing on the inter-individual variability of the native knee, tibia and femur with regards to the coronal or sagittal alignment is lacking. The aim of this study was to analyse normal angular values in the healthy middle-aged population and determine differences of angular values according to inter-individual features. The first hypothesis was that common morphological patterns may be identified in the healthy middle-aged non-osteoarthritic population. Read More

Total hip arthroplasty combined with subtrochanteric shortening osteotomy for Crowe type IV hip dysplasia in dwarfism: a case report.

J Int Med Res 2020 May;48(5):300060520921334

Department of Osteopathy, The Third Hospital of Hebei Medical University, Shijiazhuang, Hebei Province, China.

Dwarfism is a condition of extreme short stature. Total hip arthroplasty (THA) in patients with dwarfism is a very demanding procedure due to their specific joint deformity and small bone size, which increases the technical difficulty of the THA procedure in such patients with hip dysplasia. This current case report describes a 29-year-old female patient that was admitted due to shortening of the right lower limb, as compared with the contralateral side, which had been present for 18 years.
