This study aimed to evaluate implant survival of reverse hybrid
total hip arthroplasty (THA) at medium-term follow-up. A consecutive series of 1082 THAs in 982 patients with mean follow-up
of 7.9 years (5 to 11.3) is presented. Mean age was 69.2 years (21
to 94). Of these, 194 (17.9%) were in patients under 60 years, 663
(61.3%) in female patients and 348 (32.2%) performed by a trainee.
Head size was 28 mm in 953 hips (88.1%) or 32 mm in 129 hips (11.9%).
Survival analysis was performed and subgroups compared using log
rank tests.Aims
Patients and Methods
Reverse hybrid total hip replacement (THR) offers significant theoretical benefits but is uncommonly used. Our primary objective was to evaluate implant survival with all cause revision and revision for aseptic loosening of either component as endpoints. Data was collected prospectively on 1, 088 (988 patients) consecutive reverse hybrid THRs. Mean patient age was 69.3 years (range, 21–94) and mean follow-up was 8.2 years (range, 5–11.3). No patients were lost to follow-up. Overall, 194 (17.8%) procedures were performed in patients under 60 years, 666 (61.1%) were performed in female patients and 349 (32.1%) were performed by a trainee. Acetabular components were ultra-high molecular weight polyethylene in 415 (38.1%) hips, highly cross-linked polyethylene in 669 (61.5%) hips and vitamin E stabilised polyethylene in 4 (0.4%) hips. Femoral stems were collared in 757 (69.7%) hips and collarless in 331 (30.3%) hips. Femoral head sizes were 28 mm in 957 (87.9%) hips and 32 mm in 131 (12.1%) hips. Survival analysis was performed using Kaplan Meier methodology. Log rank tests were used to asses differences in survival by age, gender, head size and surgeon grade.Introduction
Patients/Materials & Methods
Increasing demand for total hip and knee arthroplasty (THA/TKA)
and associated follow-up has placed huge demands on orthopaedic
services. Feasible follow-up mechanisms are therefore essential. We conducted an audit of clinical follow-up decision-making for
THA/TKA based on questionnaire/radiograph review compared with local
practice of Arthroplasty Care Practitioner (ACP)-led outpatient
follow-up. In all 599 patients attending an ACP-led THA/TKA follow-up
clinic had a pelvic/knee radiograph, completed a pain/function questionnaire
and were reviewed by an ACP. An experienced orthopaedic surgeon
reviewed the same radiographs and questionnaires, without patient
contact or knowledge of the ACP’s decision. Each pathway classified
patients into: urgent review, annual monitoring, routine follow-up
or discharge. Aims
