Primary Total Hip Arthroplasty

AbstractThis study aimed to evaluate the early results of primary total hip arthroplasty (THA) using dual mobility (DM) cups in patients at a risk of dislocation and compare them with that of fixed bearing (FB) THA. This retrospective study included patients who had undergone primary THA between January 2016 and December 2018 and were at a risk of dislocation. A propensity score-matched analysis was conducted for 63 THA procedures with vitamin-E infused highly cross-linked polyethylene (VEPE) DM bearing and 63 THA procedures performed with FB from the same manufacturer for a mean follow-up period of 3.1 and 3.5 years, respectively. The radiologic outcomes at the last follow-up and incidence of postoperative complications were evaluated and compared statistically between the two groups. The modified Harris hip score (mHHS) was used to assess patient-reported outcomes. Postoperative dislocation occurred in 4 cases (6.3%) in the FB group, but did not occur in the DM group (p = 0.042). There was no difference in the radiologic outcomes and postoperative complications between the two groups. The mHHS at the last follow-up showed satisfactory outcomes in both the groups (DM group, 90.5; FB group, 88.1), without a statistical difference between the groups. The early results of THA using VEPE DM bearing showed better outcomes than that of THA with FB for patients at a risk of dislocation. A longer follow-up period is recommended to assess the stability and overall outcomes.

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.

Primary Total Hip Arthroplasty

Background: Introduction of new implants should be monitored closely to capture any signs of compromising patient safety. Vitamin E infused highly-crosslinked polyethylene liners (VEPE) offer the potential for reduced wear. Highwall liners have been hypothesised to result in increased wear and potential liner fractures. The aim of this study was to determine the 3–7-year follow-up of highwall VEPE for primary total hip arthroplasty (THA), focusing on liner-related complications. Methods: We included 1221 consecutive THA operations from July 2010 to May 2014 with minimum follow-up of 3 (3.1–6.8) years Data collected included demographics, implant data, complications, reoperations, and deaths. Data were cross-referenced with the Danish Hip Arthroplasty Registry in order to ensure validity and completeness. Acetabular shell position was measured using Martell Hip Analysis Suite in a subgroup of 931 THAs. Results: Cumulative stem revision and shell revision at 3-year follow-up was 3.4% and 0.4% respectively. There were no revisions due to liner failure. Reason for revision included 11 dislocations, 15 soft-tissue revisions for infection, 44 stem revisions of which 34 were periprosthetic fractures and 13 shell revisions of which 6 were combined shell and stem revisions. Conclusion: Early follow-up of VEPE liners for primary THA have not shown any revisions associated with liner failure. Continued monitoring of new materials are necessary to capture any signs of compromised patient safety.

Primary Total Hip Arthroplasty

AbstractGunshot wound (GSW) injuries around the hip joint can lead to debilitating post-traumatic arthritis, requiring a technically demanding primary total hip arthroplasty (THA). These surgeries are often complicated by bullet debris, extensive scaring, prior operations, and altered local anatomy. Although most literature focuses on acute management of GSW around the hip, a few reports detail the mid-term outcomes of GSW patients with primary THA for post-traumatic arthritis. The purpose of this study was to assess the outcomes and complications associated with THA in nine patients with secondary arthritis due to prior GSW injuries. At a mean follow-up of 35 months (range 12–60 months), significant improvement was shown in hip function, activity, and pain levels, and was similar to the outcomes of 18 patients who underwent primary THA for degenerative joint disease. While technically demanding, THA seems to reduce pain and improve function safely and effectively for patients with GSW-induced hip arthritis.
