Article entitled ¿the effect of implant modification the low contact stress experience¿ written by a.Pineda, m.B.Pabbruwe, a.M.Kop, p.Vlaskovsky, and m.Hurworth published in the bone and joint journal science direct in 2019 as reviewed.The aim of this study was to conduct the largest low contact stress (lcs) retrieval study to elucidate the failure mechanisms of the porocoat and duofix femoral component.The latter design was voluntarily recalled by the manufacturer.The study included 104 revised uncemented lcs implants which were analyzed.Patients were either implanted with porocoat implants for duofix implants.Adverse events (based off the aes provided patients experienced more than one adverse event and the data is summarized) reason for removal/observation at removal adverse event(s) possibly associated with unk lcs femoral component 104 device revision and replacements 67 for pain 27 for implant loosening (bone to implant) 29 for joint instability 10 for infection 14 for implant mispositioning 9 for joint stiffness 8 for metallosis 33 for debris tissue staining 26 for bone reabsorption 53 for scar tissue 3 for heterotopic ossification 8 for effusion/cyst adverse event(s) possibly associated with unk lcs tibial component 104 device revision and replacements 67 for pain 27 for implant loosening (bone to implant) 29 for joint instability 10 for infection 14 for implant mispositioning 9 for joint stiffness 8 for metallosis 33 for debris tissue staining 26 for bone reabsorption 53 for scar tissue 3 for heterotopic ossification 8 for effusion/cyst adverse event(s) possibly associated with unk lcs tibial insert 104 device revision and replacements 67 for pain 29 for joint instability 10 for infection 9 for joint stiffness 8 for metallosis 23 for osteolysis 33 for debris tissue staining 26 for bone reabsorption 53 for scar tissue 3 for heterotopic ossification 8 for effusion/cyst.
