Background: Arthroplasty is the treatment of choice for elderly patients with displaced femoral neck fractures. When compared to total hip arthroplasty (THA), higher revision rates have been reported for hemiarthroplasty (HA). Conversion of failed HA to THA can be complex, especially in the elderly population at risk for revision surgery complications. We report a single institution’s experience with conversion of failed HA to THA at mid-term follow-up. Methods: We identified patients converted from failed HA to THA from 2006 to 2016. Clinical data including indication for index and conversion surgery, maintenance or revision of femoral component during conversion, operative time, estimated blood loss, postoperative complications, and need for revision surgery were collected. Descriptive statistics were analysed in SPSS. Results: The cohort included 21 men and 39 women (mean age of 74.5 years). The mean follow-up after conversion HA to THA was 2.8 years. During conversion surgery, the femoral component was revised in 75.0% and retained in 25.0% of cases. After conversion HA to THA, the rate of major complications and re-revision at 2 years was 11.7% and 10.0%, respectively. Femoral revision versus retention did not affect complication rates (11.1% vs. 6.7%; p = 0.31) or re-revision rates (8.9% vs. 13.3%; p = 1.0). Conclusions: In this high-risk population, mid-term follow-up demonstrated tolerable complication and re-revision rates, the majority of which were for instability. We observed high rates of femoral component revision during conversion THA, although this did not increase the likelihood of postoperative complications or need for future surgery.

Abstract Background: This study estimated the short-term clinical safety and efficacy of hemispherical with flattened pole cobalt-chromium metal-back dual-mobility acetabular cup with porous outer hydroxyapatite coating and anchoring screw and pods (HFPC-DMR-HA) or cement fixation (HFPC-DM-CEM), in revision or complex total hip arthroplasty.Methods: Single-center retrospective observational cohort study of consecutively operated patients who underwent THA with an HFPC-DMR-HA or HFPC-DM-CEM cup 2 years prior to study start. Prospective 2-year follow-up with letter and phone questionnaires.Results: Sampling frame: 203 patients including 9.85% in the two cohorts with 15 HFPC-DMR-HA and 5 HFPC-DM-CEM. 3 (20%) and 2 (40%) patients were lost to follow-up, respectively. Median age was 85.6 years (range: 45.1 ; 93.3) and 78.8 (range: 68.8 ; 86.9). Median follow-up (years): HFPC-DMR-HA: 2.3, HFPC-DM-CEM: 3.3. Clinical indications: HFPC-DMR-HA 67% revision & 33% primary THAs, HFPC-DM-CEM 100% revision. Primary endpoint: 2-year implant survival rate: HFPC-DMR-HA 93% [59, 99], HFPC-DM-CEM 100%. Prosthetic dislocation: HFPC-DMR-HA 1 (6.7%), HFPC-DM-CEM 0%. Secondary endpoint: Modified HHS (pain & functional subscore) improved with HFPC-DMR-HA from baseline 26.8 [14.9, 38.7] to 82.2 [73.5, 90.9] at 2-year follow-up (p<0.0001); HFPC-DM-CEM from 41.6 [24.9, 58.3] to 80.7 [55.8, 100].Conclusions: The authors deemed the short-term outcomes with these acetabular cups in revision or complex total hip arthroplasty to be satisfactory.Study registration: clinicaltrials.gov NCT04209426.

Abstract Background: This study estimated the short-term clinical safety and efficacy of hemispherical with flattened pole cobalt-chromium metal-back with porous outer hydroxyapatite coating dual-mobility acetabular cup (HFPC-DM-HA) in primary total hip arthroplasty.Methods: Single-center retrospective observational cohort study of consecutive patients undergoing total hip arthroplasty with a HFPC-DM-HA 2 years prior to study start. Prospective 2-year follow-up with letter and phone questionnaires.Results: Sampling frame: 361 patients including 59 patients (16.3%) in the cohort. 6 patients (10%) lost to follow-up. Median age 77.5 years (range: 67 ; 92), 32% female, median BMI 25.2 kg.m-2 (18.4 to 56.8). Clinical indications: Primary THA in all patients, resulting from primary osteoarthritis in 80% of them. Median follow-up 3.0 years (2.7 to 4.1). Primary endpoint: 2-year implant survival rate: 97% [87, 99]. Prosthetic dislocation: 0%. Secondary endpoint: Modified HHS (pain & functional subscore) improved from baseline 39.7 [34.6, 44.7] to 75.8 [72.1, 79.6] at 1-year and to 86.7 [83.7, 89.7] at 2-year follow-up (p<0.0001).Conclusions: The authors deemed the short-term outcomes of this acetabular cup in primary total hip arthroplasty to be satisfactory.Study registration: clinicaltrials.gov NCT04209374.
