Histopathological evaluation of spontaneous osteonecrosis of the knee: time to reconsider history and nomenclature-a scoping review.

Spontaneous osteonecrosis of the knee (SONK) was first described by Ahlbäck et al. in 1968. However, subsequent studies revealed that subchondral fractures, rather than necrosis, are the most common histopathological finding in bone samples from patients diagnosed with SONK.

Planning Accuracy and Stem Offset Assessment in Digital Two-Dimensional Versus Three-Dimensional Planning in Cementless Hip Arthroplasty: A Systematic Review and Meta-Analysis.

Total hip arthroplasty (THA) planning is crucial for restoring hip function and minimizing complications. The present systematic review and meta-analysis aimed to assess and compare the accuracy of 2D versus 3D preoperative planning in THA. : The inclusion criteria were randomized controlled trials (RCTs) and observational studies (ROSs) published in English comparing the accuracy of 2D and 3D preoperative planning for total hip arthroplasty.

How to Improve Meniscal Repair through Biological Augmentation: A Narrative Review.

Since the role of the menisci in knee stability, proprioception, and homeostasis has been well established, significant efforts have been made to repair meniscal tears, resulting in excellent clinical outcomes and a reduction in the progression of knee osteoarthritis (OA). However, varying failure rates have been reported, raising questions regarding the healing potential in cases of complex injuries, poorly vascularized and degenerated areas, and generally in the presence of unfavorable biological characteristics. Therefore, over the last few decades, different strategies have been described to increase the chances of meniscal healing.

Knee osteonecrosis after SARS-CoV-2 infection: a systematic case-based review.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the virus responsible for coronavirus disease 2019 (COVID-19). Patients with COVID-19 manifested symptoms mainly related to the respiratory system, but also the musculoskeletal system can be involved. COVID-19 has been described as a possible cause of knee osteonecrosis (ON).

Hip resurfacing versus total hip arthroplasty: a systematic review and meta-analysis of randomized clinical trials.

Purpose: Total hip arthroplasty (THA) is the gold standard in the treatment of advanced hip osteoarthritis. However, hip resurfacing (HR) arthroplasty may present a viable alternative. The aim of this study was to compare complications, implant survivorship, and functional outcomes between HR and THA, to assess HR as a valid and safe alternative to THA.
