Long-term outcomes of total elbow arthroplasty: a systematic review of studies at 10-year follow-up.

Abstract

The purpose of this study was to systematically review the literature to evaluate the functional outcomes, dislocation, and revision rates following total elbow arthroplasty (TEA) at a minimum 10 years' mean follow-up. Two independent reviewers performed a literature search using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines using PubMed, Embase, and Cochrane Library databases. Studies were only included if they focused on outcomes post-TEA at a minimum 10 years' mean follow-up. Our search found 23 studies including 1429 elbows (60.4% linked TEA) that met our inclusion criteria. There were 1276 patients (79.0% female), with an average age of 64.7 years (19-93) and a mean follow-up of 137.2 months (120-216). At final follow-up, the mean Mayo Elbow Performance Score, Oxford Elbow Score, and Quick Disabilities of the Arm, Shoulder, and Hand scores were 89.1 (35-100), 64.4 (16-48), and 39.2 (3-93), respectively, and 63.3% of patients reported having no pain. The rates of aseptic loosening, infection, implant dislocation, and nerve injury were 12.9%, 3.3%, 4.2%, and 2.1%, respectively. The overall complication and revision rates were 16.3% and 14.6%, respectively. Our systematic review established that TEA offers patients satisfactory clinical outcomes at long-term follow-up, with relatively stable revision and complication rates compared to short and medium term.
