Background: Periacetabular osteotomy (PAO) treats developmental dysplasia of the hip (DDH) by reducing load on the hip and improving joint function. Untreated DDH affects lower extremity alignment and alters knee morphology, with valgus alignment more pronounced in hip osteoarthritis secondary to DDH. While PAO may influence knee mechanics, its association with subchondral bone density in the tibiofemoral joint remains unclear.

Introduction: Mueller-Weiss syndrome is a rare condition seen in adults due to spontaneous osteonecrosis of tarsal navicular bone unlike Koehler's disease which is quite common in paediatric population.
Case Report: We report a single case of Mueller-Weiss syndrome in an adult female. After a trail of conservative treatment, operative management was done with excision of necrotic fragment and arthrodesis of mid-foot joints augmented with tricortical iliac crest graft.

Background: Legg-Calve-Perthes Disease (LCPD) is described as idiopathic avascular osteonecrosis of the capital femoral epiphysis in pediatrics. LCPD is usually present in children between 2 and 15 years and happens more frequently in boys more than girls; this study aims to compare the outcome of two surgical methods in treating LCPD.
Methods: We included sixty patients with unilateral LCPD who underwent Salter or femoral varus osteotomy from 2007 to 2017.

The aim of this article is to determine the safety and efficacy of core decompression (CD) combined with injection of autologous bone marrow concentrate (BMC), demineralized bone matrix (DBM), and platelet-rich fibrin (PRF) for treating femoral head osteonecrosis. Seventy-seven patients (53 males and 24 females) for a total of 87 hips were treated for hip osteonecrosis with CD combined with injection of autologous BMC, DBM, and PRF at Rizzoli Orthopedic Institute from September 2008 to December 2019. Patients were assessed at baseline, at 45 days, and at 3, 6, 12, 24, and 36 months postoperatively.

Core decompression was developed as a joint-preserving procedure for patients with early-stage osteonecrosis of the femoral head. Previous studies indicated a high success rate that outperforms nonoperative management of pre-collapse hips. The traditional single-tunnel core decompression technique uses a cannulated drill bit inserted into the lateral cortex of the proximal femur.
