Cup Positioning

Background: Acetabular cup positioning is vital to the long-term survivorship of total hip arthroplasty (THA). Malalignment has been linked to dislocation, wear and osteolysis. Although there are many studies demonstrating the reduction in variability of cup positioning with computer-assisted techniques, there are relatively few reporting long-term patient reported outcomes and revision rates. Aim: The aim of this study was to review whether those patients who underwent navigated THA had better long-term survivorship or better patient reported outcomes. Methods: We compared revision rates and Oxford hip scores of 152 THAs (47 navigated and 105 non-navigated) performed at a single site between 2003 and 2008, with a minimum follow-up of 10 years. Results: 9 of the non-navigated and none of the navigated hips were revised at 10 year follow-up (p=0.057). There were no observable differences in 10-year Oxford hip scores between the navigated and non-navigated hips, 44.82 and 43.38 respectively. Conclusion: With respect to the rate of revision, although statistical significance was not achieved, it can be shown from our data that there was a clinically significant reduction in revision rates with navigated vs. non-navigated techniques. More data with higher patient numbers in the navigated cohort may be required to validate the results of our study.

Background: Polycarbonate urethane (PCU) is a bearing surface with a lower modulus of elasticity than polyethylene or ceramic and is thought to more closely replicate the tribology of native hyaline cartilage. The purpose of this study was to determine the clinical outcomes with the use of PCU in elective total hip arthroplasty (THA). Methods: We carried out a prospective observational study in which 157 patients underwent elective THA with a metal-on-PCU hip system. Patients had radiographic follow-up at 6 months and 3 years after surgery. Oxford Hip Scores and EuroQol scores were obtained annually and Harris Hip Scores were obtained at 6 months and 3 years after surgery. Results: 180 hips were implanted, of which, 149 hips reached 3-year review with no revisions. There was an increase in Harris Hip Scores, Oxford Hip Scores and EuroQol scores ( p < 0.001). 12 patients (12 hips) reported painless hip squeaking. There were no dislocations and no other adverse events were reported. Conclusion: Our results showed satisfactory survivorship and improvements in patient reported outcomes with metal on PCU THA. Long-term data are still being collected to confirm these findings. We recommend further tribological research into the squeaking phenomenon we observed.

Background Osteonecrosis of the hip is a clinical, radiographic, and pathologic entity that commonly affects young patients. This study evaluates long-term implant survival and patient-reported outcomes after primary total hip arthroplasty (THA) in patients with osteonecrosis aged 35 or younger. Methods A retrospective study with prospective follow-up was conducted at a major academic medical center. Chart review was performed to identify young THA patients with osteonecrosis, and follow-up surveys were conducted to determine implant survival and patient-reported outcomes. Kaplan-Meier survival analysis was performed to evaluate implant survival, and the hip disability and osteoarthritis outcome score (HOOS) was used to describe patient-reported outcomes. Results The study included 135 patients (204 THAs) with a mean time to follow-up of 14 years. In this group, 10-year implant survival was 86% and 20-year implant survival was 66%. Implant survival was longer in male patients (p = 0.02) and patients that were over the age of 25 at the time of surgery (p = 0.03). The mean HOOS scores at follow-up were 87 for pain, symptoms, and ADLs, and 77 for sports. All HOOS measures were lower in patients that underwent a revision THA, and HOOS-Pain and HOOS-Sport scores were lower in patients that were over the age of 25 at the time of surgery (p<0.05). Conclusions Young patients with osteonecrosis have good implant survival and long-term outcomes after THA. Patient factors and implant characteristics should be considered when predicting implant survival and outcomes after THA in young patients with osteonecrosis.

Acetabular Overcoverage

Background: Patients with pincer-type femoroacetabular impingement are commonly treated with arthroscopic reduction of acetabular depth as measured by the lateral center-edge angle (LCEA). The optimal amount of rim reduction has not been established, although large resections may increase contact pressures through the hip. A recent publication demonstrated inferior surgical outcomes in patients with acetabular overcoverage as compared with normal acetabular coverage. Casual observation of our database suggested equivalent improvements, prompting a similar analysis. Purpose: To analyze patient-reported outcomes after hip arthroscopy for femoroacetabular impingement in patients with acetabular overcoverage who were matched with controls with normal coverage, as well as to analyze associations with reduction in LCEA. Study Design: Cohort study; Level of evidence, 3. Methods: Data were collected prospectively from patients with a minimum 2-year follow-up after receiving hip arthroscopy for femoroacetabular impingement by a single surgeon. Cases were reviewed to identify those with pincer-type morphology (LCEA >40°) and matched according to sex, age, chondral damage, and surgery date in a 1:1 ratio with controls with an LCEA of 25° to 40°. The surgical goal was to reduce the LCEA to the upper end of the normal range with minimal rim resection, usually 35° to 37°. Radiographic measurements of coverage, intraoperative findings, procedures, and patient-reported outcomes were recorded, including the 12-Item International Hip Outcome Tool, Non-arthritic Hip Score, Hip Disability and Osteoarthritis Outcome Score, visual analog scale for pain, rates of revision or reoperation, and conversion to total hip arthroplasty. Results: A total of 114 hips (93 patients) for the pincer group were matched 1:1 from 616 hips (541 patients) for the control group. The pincer group (mean ± SD age, 34.5 ± 12.2 years) did not differ in age, body mass index, or follow-up from controls. LCEA was reduced in both groups pre- to postoperatively: the pincer group from 44.0° ± 2.8° to 34.2° ± 3.5° and the controls from 32.9° ± 3.9° to 31.0° ± 3.0°. No differences in improvement were observed: iHOT-12 improved by 35.7 points in both groups ( P = .9 for analysis of variance interaction) and Nonarthritic Hip Score by 22.3 points ( P = .6). From all eligible surgical procedures, 2-year follow up rates were 2.5% and 2.6% for the pincer and control cohorts, respectively, and 1.2% and 0.3% for conversion to total hip arthroplasty. Conclusion: Arthroscopic management of acetabular overcoverage can achieve excellent results, equivalent to arthroscopy for other causes of symptomatic femoroacetabular impingement. A key finding was smaller rim resections producing a mean postoperative LCEA of 34.2° with a small standard deviation.

AbstractTotal hip arthroplasty (THA) in pediatric patients is controversial with concern for high failure rates, and lack of promising outcomes as compared with the adult population. Increased survivorship of implants invites the potential for improved function and quality of life in young adults. Although THA is now an option for end-stage symptomatic hip disease in young patients, outcomes with contemporary techniques and implants have yet to be reported.Following the institutional review board approval, a retrospective chart review of 25 patients (29 hips) with end-stage hip disease at a single institution from 2010 to 2017 was performed. All patients underwent THA with noncemented, contemporary THA with highly cross-linked polyethene liners. Clinical, radiographic, and patient-reported outcomes were obtained including any postoperative complications, revisions, evidence of loosening or wear, and lastly, Western Ontario & McMaster Universities Osteoarthritis Index, Harris Hip Scores, Non-Arthritic Hip scores, and International Hip Outcome Tool. With a minimum follow-up duration of 2 years, there were no revisions or evidence of loosening or wear on follow-up radiographs. All patients underwent noncemented THA with metal or ceramic on highly cross-linked polyethylene liners. Six patients accounting for seven THAs completed patient-reported outcomes: two reporting excellent outcomes, four good outcomes, and one failed outcome. With advancing techniques and strategies, treatment options for hip pathology in the pediatric population are growing. We present favorable outcomes 2 years post-procedure, suggesting THA as a potential option for end-stage hip disease in pediatric and young adult patients.

AbstractFemoral neck-preserving short- (NPS) stem implants for total hip arthroplasty (THA) bear several advantages over longer-stem implants, such as native hip structure preservation and improved physiological loading. However, there still is a gap of knowledge regarding the potential benefits of a short-stem design over conventional neck-sacrificing stems in regards to patient-reported outcomes (PROs). The authors investigated the differences in PROs between a neck-sacrificing stem design and NPS stem design arthroplasty. They hypothesized that PROs of NPS stem THA would be higher in the medium-term in comparison to the neck-sacrificing implant system. Neck-sacrificing implant patients (n = 90, age 57 ± 7.9 years) and a matched (body mass index [BMI], age) cohort group of NPS implant patients (n = 105, age 55.2 ± 9.9 years) reported both preoperative and postoperative hip disability and osteoarthritis outcome scores (HOOS). Average follow-up was 413 ± 207 days (neck sacrificing implant) and 454 ± 226 days (NPS implant). The authors applied multivariate analysis of variance (MANOVA) and Mann–Whitney tests for statistical analyses. Significance levels were Holm–Bonferroni adjusted for multiple comparisons. HOOS Subscores increased significantly after surgery independent of implant type (p < 0.001). There was a significant time by surgery interaction (p = 0.02). Follow-up HOOS subscores were significantly higher in the NPS implant group: symptoms (p < 0.001), pain (p < 0.001), activities of daily living (ADL; p = 0.011), sports and recreation (p = 0.011), and quality of life (QOL; p = 0.007). While long-term studies are required for further investigation, evidence from the current study suggests that NPS implants may provide a significant benefit to primary THA patients, which could be due to physiological loading advantages or retention of bone tissue.

Introduction: The Chiari pelvic osteotomy (CPO) has been recommended as a salvage procedure to improve head coverage in case of hip joint incongruence in paediatric hip disease. In this study, we aimed to assess the long-term results of CPO for severe Legg-Calvé-Perthes disease (LCPD). Methods: A total of 39 patients who underwent a CPO at our department between 1995 and 2010 were prospectively followed both radiologically (Stulberg classification) and clinically (Harris Hip Score [HHS], conversion into total hip arthroplasty). In this study, we retrospectively reviewed the cases of 12 hips (12 patients, 3 girls, 8 left hips) treated by CPO for severe LCPD (Catterall grade 3 or 4) with hip joint incongruence. Mean follow-up was 14.0 (range 7.6–21.3) years. Results: Mean age at surgery was 10.2 (range 8.2–17.8) years. Additional femoral osteotomy was performed in 8 patients. A good radiological result (Stulberg I or II) was achieved in 2 patients, a fair result (Stulberg III) in 4 patients, and a poor outcome (Stulberg IV or V) in 6 patients. Mean postoperative HHS averaged 93 (range 65–100) points. An excellent functional outcome (HHS 90–100 points) was achieved in 9 patients. No patient underwent total hip arthroplasty during follow-up. Postoperative limb-length discrepancy was found in 3 patients. Conclusions: CPO for severe LCPD with hip joint incongruence resulted in good long-term clinical outcome in about ⅔ of our patients after a mean of 14 years. Our results suggest that CPO can still be considered as a salvage joint-conserving procedure in this selected group of younger patients.

Patient Acceptable Symptom State

The Forgotten Joint Score-12 (FJS-12) is a valid patient-reported outcome measures (PROMs) used to assess prosthesis awareness during daily activities after total hip arthroplasty (THA). The minimum clinically important difference (MCID) can be defined as the smallest change or difference that is evaluated as beneficial and could change the patient’s clinical management. The patient acceptable symptom state (PASS) is considered the minimum PROMs cut-off value that corresponds to a patient’s satisfactory state of health. Despite the validity and reliability of the FJS-12 having been already demonstrated, the MCID and the PASS of this score have not previously been defined. Patients undergoing THA from January 2019 to October 2019 were assessed pre-operatively and six months post-surgery using the FJS-12, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Oxford Hip Score (OHS). Pre-operative and follow-up questionnaires were completed by 50 patients. Both distribution-based approaches and anchor approaches were used to estimate MCID. The aim of this paper was to assess the MCID and PASS values of FJS-12 after total hip replacement. The FJS-12 MCID from baseline to 6 months post-operative follow-up was 17.5. The PASS calculated ranged from 69.8 to 91.7.
