Abstract Background Legg-Calve-Perthes disease (LCPD) is a childhood condition characterized by femoral head osteonecrosis. The osteonecrotic lesion eventually heals, but persistent deformity to the proximal femur and acetabulum might induce hip discomfort and dysfunction following recovery. Previous reports have noted that between 30% and 50% of individuals affected by LCPD to have residual hip symptoms that persist and a frequent precursor to hip osteoarthritis in young adulthood. Aim of the Work The aim of the present study is to review the efficacy of intra-articular procedures through surgical hip dislocation approach to residual hip deformity secondary to Legg- Calve-perthes disease. Patients and Methods A Systematic Review and Meta-Analysis, We will include: Randomized control trails (RCTs), controlled clinical trials, retrospective cohort studies and we will exclude: case reports, case series studies, cross sectional studies and non English studies. Results The surgical hip dislocation approach allows the surgeon to dynamically evaluate the hip, identify sources of impingement, and treat intraarticular and extraarticular abnormalities. Conclusion Head and neck osteochondroplasty performed through the surgical dislocation approach, combined with other procedures such as FHRO, RFNL, ITO and acetubular osteotomies relieved pain, improved ROM and restored function in most patients with no major complications.
