Comparing supine CT scanogram and standing long-leg radiograph for postoperative alignment in total knee arthroplasty: a prospective study.
Arch Orthop Trauma Surg
December 2024
Sitaram Bhartia Institute of Science and Research, New Delhi, India.
Purpose: Achieving precise postoperative alignment is critical for the long-term success of total knee arthroplasty (TKA). Long-leg standing radiograph (LLR) at 6 weeks post-op is the gold standard for assessing alignment, but its reliance on weight-bearing and positioning makes it less practical in the early postoperative period. Supine computed tomography scanogram (CTS) offers a potential alternative.

Foot Ankle Int
November 2024
Division of Foot and Ankle Surgery, Department of Orthopaedic Surgery, Duke University School of Medicine, Durham, NC, USA.
Article Synopsis
- The study examines differences in foot deformities, specifically Progressive Collapsing Foot Deformity (PCFD) with and without Hallux Valgus (HV), using weightbearing computed tomography in patients aged 18 and over.
- Findings show that PCFD with HV exhibits greater angles and pronation at key joints compared to PCFD without HV, indicating significant structural variations.
- The results highlight important associations between HV deformity and specific foot angles, suggesting a need for targeted clinical assessment and treatment based on these deformities.
[Application of distal radius coronal bone structure matching in the treatment of distal radius fractures].

Article Synopsis
- This study aimed to assess the impact of coronal bone structure matching (CBSM) on the treatment outcomes for patients with distal radius fractures.
- A total of 39 patients underwent surgery, divided into two groups based on whether their CBSM measurements were within the normal range (matched group) or not (mismatched group).
- Results showed that all patients healed successfully without complications, and the study evaluated healing, wrist motion, functional outcomes, and pain levels after an average follow-up of 9.5 months.
How Do Changes in Femoral Anteversion Impact Femoral Rotation and Anterior Offset After Total Hip Arthroplasty?
J Arthroplasty
January 2025
Corin Group, Cirencester, Gloucestershire, United Kingdom.
Background: The impact of femoral anteversion changes on femoral rotation and anterior offset following total hip arthroplasty (THA) has not been well studied. This study therefore investigated the relationship among femoral anteversion, anterior offset, and femoral rotation before and after THA.
Methods: There were 995 patients who had staged primary bilateral THAs who received a preoperative supine computerized axial tomography (CT) scan, following a standardized protocol, for surgical planning prior to each THA.
Cementless, Cruciate-Retaining Primary Total Knee Arthroplasty Using Conventional Instrumentation: Technical Pearls and Intraoperative Considerations.
JBJS Essent Surg Tech
September 2024
Department of Orthopaedic Surgery, The Johns Hopkins Hospital, Baltimore, Maryland.
Article Synopsis
- Total knee arthroplasty (TKA) is a common surgical procedure for patients with severe knee osteoarthritis, especially when non-surgical treatments fail, leading to significant improvements in pain, function, and quality of life.
- The procedure can use various components (cemented, cementless, or a hybrid) and is generally performed with a focus on mechanical alignment, although newer alignment strategies like gap and kinematic balancing are showing promising results in early studies.
- The preferred surgical technique for cementless TKA involves a specific patient positioning and incision approach, starting with the application of a thigh tourniquet and a parapatellar incision, ensuring proper alignment and access during the surgery.*
