{"cited_by_count":1436332,"description":"This cluster of papers focuses on advancements in hip arthroplasty techniques and materials, including the use of metal-on-metal bearings, the impact of wear particles and osteolysis, implant failure and revision surgery, as well as the potential health effects of cobalt toxicity. It also explores minimally invasive approaches and the management of femoral fractures associated with hip replacements.","display_name":"Orthopaedic implants and arthroplasty","domain_id":"4","external_ids":{"openalex":"https://openalex.org/T10512","wikipedia":"https://en.wikipedia.org/wiki/Hip_replacement"},"field_id":"27","id":"T10512","keywords":[{"display_name":"total hip arthroplasty","id":"hip-arthroplasty","score":0.4766,"url":"https://openalex.org/keywords/hip-arthroplasty"},{"display_name":"hip prosthesis","id":"hip-prosthesis","score":0.6506,"url":"https://openalex.org/keywords/hip-prosthesis"},{"display_name":"revision hip arthroplasty","id":"revision-hip-arthroplasty","score":0.8294,"url":"https://openalex.org/keywords/revision-hip-arthroplasty"},{"display_name":"aseptic loosening","id":"aseptic-loosening","score":0.612,"url":"https://openalex.org/keywords/aseptic-loosening"},{"display_name":"Harris hip score","id":"harris-hip-score","score":0.4742,"url":"https://openalex.org/keywords/harris-hip-score"},{"display_name":"revision total hip arthroplasty","id":"revision-total-hip-arthroplasty","score":0.8201,"url":"https://openalex.org/keywords/revision-total-hip-arthroplasty"},{"display_name":"acetabular component","id":"acetabular-component","score":0.9079,"url":"https://openalex.org/keywords/acetabular-component"},{"display_name":"osteolysis","id":"osteolysis","score":0.3241,"url":"https://openalex.org/keywords/osteolysis"},{"display_name":"hip dislocation","id":"hip-dislocation","score":0.2522,"url":"https://openalex.org/keywords/hip-dislocation"},{"display_name":"polyethylene wear","id":"polyethylene-wear","score":0.6946,"url":"https://openalex.org/keywords/polyethylene-wear"},{"display_name":"implant loosening","id":"implant-loosening","score":0.4308,"url":"https://openalex.org/keywords/implant-loosening"},{"display_name":"ultra-high molecular weight polyethylene","id":"ultra-high-molecular-weight-polyethylene","score":0.2779,"url":"https://openalex.org/keywords/ultra-high-molecular-weight-polyethylene"},{"display_name":"wear debris","id":"wear-particles","score":0.3697,"url":"https://openalex.org/keywords/wear-particles"},{"display_name":"periprosthetic fracture","id":"periprosthetic-fracture","score":0.5036,"url":"https://openalex.org/keywords/periprosthetic-fracture"},{"display_name":"revision arthroplasty","id":"revision-arthroplasty","score":0.3106,"url":"https://openalex.org/keywords/revision-arthroplasty"},{"display_name":"hip resurfacing","id":"hip-resurfacing","score":0.8485,"url":"https://openalex.org/keywords/hip-resurfacing"},{"display_name":"cementless total hip arthroplasty","id":"cementless-total-hip-arthroplasty","score":0.9065,"url":"https://openalex.org/keywords/cementless-total-hip-arthroplasty"},{"display_name":"bone-implant interface","id":"bone-implant-interface","score":0.246,"url":"https://openalex.org/keywords/bone-implant-interface"},{"display_name":"acetabular component positioning","id":"acetabular-component-positioning","score":0.8992,"url":"https://openalex.org/keywords/acetabular-component-positioning"},{"display_name":"femoral stem","id":"femoral-stem","score":0.8656,"url":"https://openalex.org/keywords/femoral-stem"},{"display_name":"stress shielding","id":"stress-shielding","score":0.3234,"url":"https://openalex.org/keywords/stress-shielding"},{"display_name":"periprosthetic osteolysis","id":"periprosthetic-osteolysis","score":0.7996,"url":"https://openalex.org/keywords/periprosthetic-osteolysis"},{"display_name":"ceramic-on-ceramic bearings","id":"ceramic-on-ceramic-bearings","score":0.9607,"url":"https://openalex.org/keywords/ceramic-on-ceramic-bearings"},{"display_name":"direct anterior approach","id":"direct-anterior-approach","score":0.8319,"url":"https://openalex.org/keywords/direct-anterior-approach"},{"display_name":"bone cement","id":"bone-cement","score":0.2091,"url":"https://openalex.org/keywords/bone-cement"}],"legacy_keywords":["Hip Arthroplasty","Total Hip Replacement","Wear Particles","Metal-on-Metal Bearings","Osteolysis","Implant Failure","Revision Surgery","Cobalt Toxicity","Femoral Fractures","Minimally Invasive Approaches"],"openalex_id":"https://openalex.org/T10512","source_created_date":"2024-01-23T15:27:06","source_updated_date":"2026-10-17T03:02:00","subfield_id":"2746","url":"/topics/T10512","works_api_url":"https://api.openalex.org/works?filter=topics.id:T10512","works_count":112604,"label":"Orthopaedic implants and arthroplasty","provider":"openalex","revision":"29410194dd79d511","taxonomy_revision":"f050b5d4780b1289","title":"Orthopaedic implants and arthroplasty","kind":"topic-directory","aeo_cohort":"topic-directory","catalogue_revision":"f050b5d4780b1289","numeric_address":"36240213568020834","address_version":"morton4x16-v1","coordinates":[4,27,2746,10512],"answer_status":"Directory metadata;
