NOCONJO, L  and  NORTJE, MB. The short-term outcome of hip revision arthroplasty with Trabecular Metal™ components and augments. SA orthop. j. [online]. 2020, vol.19, n.3, pp.162-166. ISSN 2309-8309.

BACKGROUND: Highly porous Trabecular Metal™ acetabular components are increasingly being used in revision hip arthroplasty as they facilitate ingrowth, provide a useful mechanism to deal with bone loss and may decrease the risk of infection. The purpose of this audit was to describe: 1) the total number of hip arthroplasty surgeries over Ave years, the ratio of revision to primary hip arthroplasty and indications for revision; 2) the short-term outcomes of revision hip arthroplasty with Trabecular Metal™ components and augmentsMETHODS: A retrospective folder and radiograph review of all patients who had revision total hip arthroplasty (THA) at a tertiary level hospital from February 2012 to February 2017 was doneRESULTS: There were 979 THAs performed over the period - 863 (87%) primary THAs, and 116 (12%) hip revision cases performed in 107 patients. Of the 116 (107 patients) hip revisions, there were seven (6%) re-revisions in Ave patients. The indications for revision were aseptic loosening 67 (59%), septic loosening 11 (10%), liner wear 18 (16%), periprosthetic fracture Ave (4%), other 15 (13%). Trabecular Metal™ was used for revision in 16 hips (14 patients), which is 14% of the total 116 revisions. There were ten females and four males with an average age of 61 years. The average duration of follow-up in this group was 18.5 months (1.5-39.2). In these 16 Trabecular Metal™ hips, there were three (19%) early failures of fixation due to technical errorsCONCLUSION: In our institution, 12% of the arthroplasty is revision surgery. The indications for revision are similar to published literature. Trabecular Metal™ revisions had a 19% early failure rate due to technical errorLevel of evidence: Level 4
