An x-ray method is described for the determination of leg-length inequality in the standing subject, Its precision is compared to that of other methods in current use. The geometrical considerations which are inherent in any radiographic method of leg-length determination are summarized. Sixty-seven patients with OA hip were studied; 62 were considered to be idiopathic and 36 of these idiopathic cases were superolateral in type. Measurements in these 36 patients showed significant leg-length disparity, most of the diseased hips being found on the side of the longer leg. If allowance is made for shortening due to disease, the frequency and bias of the disparity are highly significant. The strong association between OA hip of this type and a long leg suggests a causal relationship.

Objective: Lower limb malalignment can complicate symptoms and accelerate knee osteoarthritis (OA), necessitating consideration in study population selection. In this study, we develop and validate a deep learning model that classifies leg alignment as "normal" or "malaligned" from knee antero-posterior (AP)/postero-anterior (PA) radiographs alone, using an adjustable hip-knee-ankle (HKA) angle threshold.
Material And Methods: We utilized 8878 digital radiographs, including 6181 AP/PA full-leg x-rays (LLRs) and 2697 AP/PA knee x-rays (2292 with positioning frame, 405 without).
Hip Dysplasia Diagnosed After Skeletal Maturity: Factors Associated With Progression to Osteoarthritis.
Iowa Orthop J

Department of Orthopedics and Rehabilitation, University of Iowa Hospitals and Clinics, Iowa City, Iowa, USA.
Background: Hip dysplasia diagnosed after skeletal maturity is distinct from developmental dysplasia of the hip (DDH) in infants and young children. While the natural history of DDH in infants and young children is well-established, the association between hip dysplasia diagnosed after skeletal maturity and osteoarthritis is less clear. This narrative review summarizes existing literature assessing characteristics of hip dysplasia diagnosed after skeletal maturity associated with progression to osteoarthritis.

Iowa Orthop J

Rothman Orthopaedic Institute, Philadelphia, Pennsylvania, USA.
Background: Dislocation remains a common complication following total hip arthroplasty (THA). Previous literature has shown that the femoral head-to-neck ratio is essential in hip motion, function, and stability. While large femoral heads and dual mobility bearings have been developed to improve stability, it remains unknown if the ratio between femoral head size to acetabular cup size also plays a role in stability.

Case Western Reserve University School of Medicine, Cleveland, Ohio, USA.
Background: The growing popularity of glucagon-like peptide-1 receptor agonists (GLP-1-RAs) for weight loss could significantly impact joint preservation and arthroplasty. While this will in part be driven by the association between obesity, osteoarthritis (OA), and total joint arthroplasty (TJA), recent evidence also indicates that GLP-1-RAs may have direct joint-protective, anti-inflammatory effects.
Purpose: To evaluate the association between GLP-1-RA use and the onset and progression of hip and knee OA in an obese population.
Association between acetabular coverage over femoral head and rate of joint space narrowing in non-arthritic hips.
Bone Jt Open
January 2025
Department of Orthopaedic Surgery, Kyoto University Graduate School of Medicine, Kyoto, Japan.
Aims: This study was performed to investigate the association between the acetabular morphology and the joint space narrowing rate (JSNR) in the non-arthritic hip.
Methods: We retrospectively reviewed standing whole-leg radiographs of patients who underwent knee arthroplasty from February 2012 to March 2020 at our institute. Patients with a history of hip surgery, Kellgren-Lawrence grade ≥ II hip osteoarthritis, or rheumatoid arthritis were excluded.
