All samples were examined at room temperature to evaluate their microstructure, mechanical and <jats:italic>in-vitro<\/jats:italic> degradation behaviour and biological properties. Results indicated that adding Sr was associated with fine average grain size, increased mechanical strength, and a decreased corrosion rate. All samples show tiny isolated and open interconnected pores (porosities: 18%\u201330%, pores: 127\u2013279 \u00b5m) with a suitable surface roughness of less than 0.5 \u00b5m. All the provided samples possess mechanical and hemocompatible properties that closely resemble natural bone. Mg\u20134Zn\u20132Sr has the highest hardness (102.61 \u00b1 15.1 HV) and compressive strength (24.80 MPa) than Mg\u20134Zn\u20130.5Sr (85 \u00b1 8.5 HV, 22.14 MPa) and Mg\u20134Zn\u20131Sr (97.71 \u00b1 11.2 HV, 18.06 MPa). Immersion results revealed that samples in phosphate-buffered saline solutions have excellent degradability properties, which makes them a promising biodegradable material for orthopaedic applications. The scaffold with the highest Sr concentration shows the best optimised mechanical and degradation behaviour out of the three porous scaffolds, with a 2.7% hemolysis rate.<\/jats:p>","DOI":"10.1088\/1748-605x\/ad2c16","type":"journal-article","created":{"date-parts":[[2024,2,22]],"date-time":"2024-02-22T22:21:52Z","timestamp":1708640512000},"page":"025050","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Exploration of microstructural characteristics, mechanical properties, and <i>in vitro<\/i> biocompatibility of biodegradable porous magnesium scaffolds for orthopaedic implants"],"prefix":"10.1088","volume":"19","author":[{"given":"Debasish","family":"Debbarma","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nikhil","family":"Anand","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7409-9344","authenticated-orcid":true,"given":"Kaushik","family":"Pal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2024,3,1]]},"reference":[{"key":"bmmad2c16bib1","doi-asserted-by":"publisher","first-page":"218","DOI":"10.5923\/j.ajbe.20120206.02","article-title":"Biomedical magnesium alloys: a review of material properties, surface modifications and potential as a biodegradable orthopaedic implant","volume":"2","author":"Eddy Jai Poinern","year":"2013","journal-title":"Am.
