Miyazaki K, Fujii M, Kawano S, Ueno M, Kitajima M, Sonohata M, Mawatari M. Functional Improvement and Patient Satisfaction Following Conversion of Fused Hip to Total Hip Arthroplasty. J Arthroplasty 2024; 39:2512-2519. [PMID: 39025276 DOI: 10.1016/j.arth.2024.07.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/30/2024] [Revised: 07/01/2024] [Accepted: 07/08/2024] [Indexed: 07/20/2024] Open
Abstract
BACKGROUND This study aimed to determine the clinical outcomes, predictors of suboptimal functional improvement, and factors influencing patient satisfaction following conversion of a fused hip to total hip arthroplasty (THA). METHODS A retrospective analysis of clinical and radiographic data was performed on 83 patients (83 hips) who underwent fused hip conversion to THA. Implant survival and predictors of poor functional outcome (Harris hip score < 70) were analyzed. In addition, factors associated with patient dissatisfaction (visual analog scale < 25th percentile) were analyzed in 63 patients (63 hips) who completed a patient-reported outcome measures questionnaire. RESULTS The median Harris hip score improved from 55 (range, 18 to 77) to 78 (range, 36 to 100) at a mean follow-up of 10.2 ± 4.8 years (P < .001). Implant survival was 97.4% at 10 years and 91.3% at 20 years, with any revision as the endpoint. Multivariate analysis identified preoperative reliance on mobility aids as an independent predictor of poor functional outcome (P = .021). There were 48 of 63 patients (76%) satisfied (satisfaction visual analog scale ≥80) with the operated hip. Demographics and preoperative/postoperative clinical data did not differ between satisfied and unsatisfied patients. Among the patient-reported outcome measures, the Forgotten Joint Score-12 emerged as an independent discriminator of patient satisfaction. CONCLUSIONS Conversion of a fused hip to THA provides functional improvement, favorable implant survival, and high patient satisfaction. However, patients dependent on mobility aids may experience suboptimal functional recovery, underscoring the need for careful preoperative counseling and patient selection.

Abstract
BACKGROUND We have innovatively developed a modified bikini direct anterior approach total hip arthroplasty (THA), endoscopy assisted minimal invasive direct anterior approach (Endo-DAA). The study compared aesthetic appearance of the scar, postoperative radiographic and functional outcomes, and complications of Endo-DAA with Bikini-DAA. METHODS Patients who underwent primary THA using Endo-DAA or Bikini-DAA were included. The main innovation of Endo-DAA is the use of minimally invasive 5-7 cm proximal transverse incision and distal puncture with an endoscopy assisted split-type tool to complete the acetabular preparation and prosthesis implantation. Outcomes evaluated included evaluation of scar satisfaction, hip reconstruction including inclination, anteversion and leg-length discrepancy (LLD) and patient-reported outcomes including Harris Hip Scores (HHS) and Forgotten Joint Score (FJS). Follow-up time points included preoperative, 6 weeks, 6 months and 12 months. RESULTS Finally, 195 hips in Endo-DAA and 207 hips in Bikini DAA completed the follow-up. The Endo-DAA group was superior to the Bikini-DAA group in the cosmetic aspects of scars. the cup anteversion angle of Endo-DAA group was significantly better than that in the Bikini-DAA group. The early HHS and FJS of the Endo-DAA group were superior to those of the Bikini-group. Operation time, blood loss, incision length, length of stay and duration to start no-assistive-device walking were also significantly better in the Endo-DAA group. Furthermore, the Bikini-DAA group had a higher incidence of complication. CONCLUSION Compared with Bikini-incision, Endo-DAA improves patients' subjective satisfaction with scar aesthetics, accelerates rapid recovery of postoperative function, and reduces postoperative complications.

Association of Pharmacologic Treatment of Depression/Anxiety With Initial Patient-Reported Outcome Measures in Patients With Hip and Knee Osteoarthritis. J Am Acad Orthop Surg 2024; 32:516-524. [PMID: 38595309 DOI: 10.5435/jaaos-d-23-00887] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Accepted: 01/27/2024] [Indexed: 04/11/2024] Open
Abstract
INTRODUCTION Depression and anxiety are common comorbidities that may exacerbate osteoarthritis (OA)-related pain. We aim to evaluate the effect of pharmacologic treatment of depression/anxiety on hip and knee patient-reported outcome measures (PROMs). METHODS A multi-institutional PROMs database was queried for patients with depression or anxiety and hip or knee OA who completed a PROMs questionnaire at an initial orthopaedic visit between January 2015 and March 2023. Data on demographics, comorbidities, and duration of pharmacologic treatment of depression/anxiety were obtained. Patients were stratified into three cohorts based on treatment duration. PROMs were compared across cohorts. RESULTS Two thousand nine hundred sixty patients who completed PROMs at their initial orthopaedic visit had both OA and depression/anxiety. One hundred thirty-four (4.5%) received pharmacologic treatment of depression/anxiety for < 1 year, versus 196 (6.6%) for more than 1 year. In unadjusted analyses, patients with pharmacologic treatment had significantly lower Patient-Reported Outcomes Measurement Information System (PROMIS)-Physical (39.8 [IQR 34.9, 44.9] vs 42.3 [37.4, 47.7], P < 0.001) and PROMIS-Mental (43.5 [36.3, 50.8] vs 48.3 [41.1, 53.3], P < 0.001) scores than those without treatment. After adjusting for demographics and comorbidities, only differences in PROMIS-Mental scores remained statistically significant, with pharmacologic treatment associated with lower scores (β = -2.26, 95% CI, [-3.29, -1.24], P < 0.001). On secondary analysis including duration of pharmacologic treatment, < 1 year of treatment was associated with significantly lower PROMIS-Mental scores than those not treated (β = -4.20, 95% CI [-5.77, -2.62], P < 0.001) while scores of patients with more than 1 year of treatment did not differ significantly from those without treatment. CONCLUSION :Our results indicate that pharmacologic treatment of depression/anxiety is associated with improved psychological health but not with improved physical symptoms related to OA. We observed a nonsignificant trend that patients with depression/anxiety who warrant pharmacologic treatment tend to have worse physical symptoms than those who do not; however, unadjusted analyses suggest this is a complex relationship beyond the isolated effect of pharmacologic treatment.

Abstract
PURPOSE To determine the respective percent thresholds for achieving the maximal outcome improvement (MOI) for the modified Harris Hip Score (mHHS), the Non-Arthritic Hip Score (NAHS), the Hip Outcome Score-Sports Subscale (HOS-SSS), the visual analog scale (VAS) for pain, and the International Hip Outcome Tool-12 (iHOT-12) that were associated with satisfaction following revision hip arthroscopy, and to identify predictors for achieving the MOI. METHODS An anchor question was provided to patients who underwent revision hip arthroscopy between April 2017 and July 2020. Patients were included for the final analysis if they answered the anchor question and had minimum 2-year follow-up. Receiver operating characteristic analysis was used to determine the thresholds for the percentage of the MOI predictive of satisfaction. A P-value of < .05 was considered significant. RESULTS In total, 318 patients underwent revision hip arthroscopy. Of those patients, 292 (91.8%) had minimum 2-year follow-up. Of this cohort, 68 answered the anchor question, with 49 (72.1%) female and 19 (27.9%) male patients. The mean age, and body mass index time were 32.9 ± 13 years and 25.4 ± 5.1, respectively. It was determined that 42.1%, 50%, 48.1%, 50%, and 50% of MOI were the thresholds for maximal predictability of satisfaction for mHHS, NAHS, HOS-SS, VAS for pain, and the iHOT-12, respectively. The presence of unaddressed subspine impingement was a significant predictor for achieving the MOI threshold for the VAS (odds ratio 1.40; 95% confidence interval 1.00-1.95; P = 0.0273). CONCLUSIONS Following revision hip arthroscopy, the percent thresholds for achieving the MOI at a minimum 2-year follow-up for the mHHS, NAHS, HOS-SS, VAS for pain, and iHOT-12 were 42.1%, 50%, 48.1%, 50%, and 50.9%, respectively. Addressing residual subspine impingement was identified as significant positive predictor for achieving the MOI. LEVEL OF EVIDENCE Level IV, case-series.

Abstract
PURPOSE The aim of this systematic review and meta-analysis was to compare joint awareness in patients who underwent total hip arthroplasty (THA) via the anterior approach (AA) versus the posterior approach (PA). The hypothesis was that patients who underwent THA via AA would have better forgetfulness of the artificial joint. METHODS A comprehensive search of major literature databases and bibliographic details was conducted to identify studies evaluating the forgotten joint score (FJS-12) in total hip arthroplasty (THA) patients operated through the anterior approach (AA) and posterior approach (PA). Out of 234 studies identified, seven studies met the inclusion criteria for review. The Newcastle-Ottawa Scale was used to evaluate the quality of evidence and the risk of bias in the included studies. The FJS-12 was evaluated at three months, one year, and beyond 2 years. RESULTS The mean FJS-12 at > 2 years was 82.03 in the AA group and 80.32 in the PA group. The forest plot analysis (n = 819 patients) revealed no significant difference in FJS-12 score between these two approaches (MD 2.13, 95% CI [- 1.17, 5.42], p = 0.21; I2 = 60%). However, the joint awareness was significantly lesser in the AA group at 3 months (MD 12.56, 95% CI [9.58, 15.54], p < 0.00001, I2 = 0%) and 1 year (MD 9.55, 95% CI [7.85, 11.24], p < 0.0001, I2 = 0%). CONCLUSIONS After analyzing the available literature, it was found that THA patients operated through the AA approach have significantly lower joint awareness than those operated through the PA approach in the first year of surgery. However, there is no significant difference in joint awareness between these two approaches after 2 years. LEVEL OF EVIDENCE III.

Abstract
Aims To evaluate mid-to long-term patient-reported outcome measures (PROMs) of endoprosthetic reconstruction after resection of malignant tumours arising around the knee, and to investigate the risk factors for unfavourable PROMs. Methods The medical records of 75 patients who underwent surgery between 2000 and 2020 were retrospectively reviewed, and 44 patients who were alive and available for follow-up (at a mean of 9.7 years postoperatively) were included in the study. Leg length discrepancy was measured on whole-leg radiographs, and functional assessment was performed with PROMs (Toronto Extremity Salvage Score (TESS) and Comprehensive Outcome Measure for Musculoskeletal Oncology Lower Extremity (COMMON-LE)) with two different aspects. The thresholds for unfavourable PROMs were determined using anchor questions regarding satisfaction, and the risk factors for unfavourable PROMs were investigated. Results The thresholds for favourable TESS and COMMON were 64.8 and 70.4 points, respectively. Multivariate analysis showed that age at surgery (p = 0.004) and postoperative leg length discrepancy (p = 0.043) were significant risk factors for unfavourable TESS results, while age at surgery (p < 0.001) was a significant risk factor for unfavourable COMMON-LE results. Following receiver operating characteristic analysis, the threshold for both TESS and COMMON-LE was 29 years of age at surgery. Additionally, a leg length discrepancy of 8.2 mm was the threshold for unfavourable TESS. Conclusion Patients aged > 29 years at the time of surgery require appropriate preoperative counselling and adequate postoperative physical and socioemotional support. Reconstruction equivalent to the length of the resected bone can reduce the risk of functional disabilities in daily living.

Abstract
BACKGROUND The Patient Acceptable Symptom State (PASS) after primary hip arthroscopy has been determined; nonetheless, the PASS still needs to be defined for revision hip arthroscopy. PURPOSE To define minimum 2-year follow-up PASS thresholds for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), visual analog scale (VAS) for pain, and International Hip Outcome Tool-12 (iHOT-12) after revision hip arthroscopy, and to identify predictors of achieving the PASS. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS Data were prospectively collected and retrospectively reviewed for all patients who underwent revision hip arthroscopy between April 2017 and July 2020. Patients were included if they had baseline and minimum 2-year follow-up scores for the mHHS, NAHS, HOS-SSS, VAS for pain, and iHOT-12. PASS was calculated using the anchor-based method. Receiver operating characteristic curve analysis was used to determine the thresholds for the PASS. A multivariate logistic regression was used to identify predictors for achieving the PASS. RESULTS A total of 318 patients who underwent revision hip arthroscopy met the inclusion criteria. Of those patients, 292 (91.8%) had baseline and minimum 2-year follow-up. Of this group, 68 patients (72.1% female and 27.9% male; mean age, 32.9 years) answered the PASS anchor question. Achievement PASS rates were 58.8%, 41.2%, 52.9%, 60.3%, and 52.9% for the mHHS, NAHS, HOS-SSS, VAS, and iHOT-12, respectively. The area under the curve (AUC) values for the PASS for mHHS, NAHS, HOS-SSS, VAS, and iHOT-12 were 0.912, 0.888, 0.857, 0.903, and 0.871, respectively, indicating excellent discrimination. The PASS for the mHHS was 76 (sensitivity, 0.809; specificity, 0.905), for the NAHS was 86.3 (sensitivity, 0.660; specificity, 1), for the HOS-SSS was 64.3 (sensitivity, 0.745; specificity, 0.905), for the VAS was 3 (sensitivity, 0.830; specificity, 0.905), and for the iHOT-12 was 64.3 (sensitivity, 0.745; specificity, 0.905). Body mass index (BMI) was identified as a significant predictor of achieving PASS for the NAHS (OR, 0.967; 95% CI, 0.940-0.996; P = .027), as patients with a BMI ≤25.4 had 1.03 times higher odds ratio of achieving PASS for the NAHS. CONCLUSION After revision hip arthroscopy, the minimum 2-year follow-up PASS thresholds for the mHHS, NAHS, HOS-SSS, VAS for pain, and iHOT-12 were 76, 86.3, 64.3, 3, and 64.3, respectively. The odds ratio of achieving PASS for the NAHS was 1.03 times higher for patients with a BMI ≤25.4.

Residual varus alignment after posterior-stabilized total knee arthroplasty limits medial soft tissue remodeling. BMC Musculoskelet Disord 2023; 24:918. [PMID: 38017454 PMCID: PMC10683269 DOI: 10.1186/s12891-023-07048-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Accepted: 11/18/2023] [Indexed: 11/30/2023] Open
Abstract
BACKGROUND Proper lower limb alignment and soft tissue balance are significant indicators to measure the success of total knee arthroplasty (TKA). Previous studies have confirmed that soft tissue relaxation around the knee after TKA will change over time; however, the relationship between lower limb alignment and soft tissue balance after TKA remains unclear. We studied (1) whether the change of soft tissue balance around the knee with time after posterior-stabilized (PS) TKA would affect the alignment of the lower limbs; (2) Whether the accuracy of lower limb alignment during PS TKA affects postoperative soft tissue remodeling. METHODS In this study, 100 patients were recruited after PS TKA. Among them, 50 patients with a hip knee ankle (HKA) angle of ≤ ± 3° were set as the neutral group, and 50 patients with an HKA angle of > ± 3° were set as the deviation group. The imaging results measured the HKA angle before the operation as well as the HKA, varus, and valgus angles at 1, 3, 6, 12, and 24 months after TKA. Clinical assessment included range of motion (ROM), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Knee Society Score (KSS). RESULTS Eight people were excluded from the study. After the exclusion, the study enrolled 47 patients in the neutral group and 45 patients in the deviant group and were followed for up to 2 years. There was no statistical significance in mean varus angles as well as HKA angle changes during the follow-up phase of each groups (P > 0.05). The mean valgus angles of the patients in the neutral group group were 2.47°, 3.45°, 3.63°, 3.60° and 3.63°, and in the deviation group were 2.45° (P = 0.841), 2.88° (P < 0.001), 3.07° (P < 0.001), 3.06° (P < 0.001), and 3.10° (P < 0.001). ROM, WOMAC and KSS of the two groups were significantly improved after operation, with no difference between the two groups. CONCLUSION This study shows that whether the alignment is accurate or not in the early stage after TKA, the relaxation of the medial and lateral soft tissues of the knee joint change; however, this change will not significantly affect the alignment of the lower limbs. Postoperative residual varus deformity limits medial soft tissue remodeling. LEVEL OF EVIDENCE III.

Abstract
Aims The Birmingham Hip Resurfacing (BHR) arthroplasty has been used as a surgical treatment of coxarthrosis since 1997. We present 20-year results of 234 consecutive BHRs performed in our unit. Methods Between 1999 and 2001, there were 217 patients: 142 males (65.4%), mean age 52 years (18 to 68) who had 234 implants (17 bilateral). They had patient-reported outcome measures collected, imaging (radiograph and ultrasound), and serum metal ion assessment. Survivorship analysis was performed using Kaplan-Meier estimates. Revision for any cause was considered as an endpoint for the analysis. Results Mean follow-up was 20.9 years (19.3 to 22.4). Registry data revealed that 19 hips (8.1%) had been revised and 26 patients (12%) had died from causes unrelated to the BHR. Among the remaining 189 hips, 61% were available for clinical follow-up at 20 years (n = 115) and 70% of patients had biochemical follow-up (n = 132). The cumulative implant survival rate at 20 years for male patients was 96.5% (95% confidence interval (CI) 93.5 to 99.6), and for female patients 87% (95% CI 79.7 to 94.9). The difference was statistically significant (p = 0.029). The mean Oxford Hip Score, Hip disability and Osteoarthritis Outcome Score, and Forgotten Joint Score were 45 (29 to 48), 89 (43 to 100), and 84 (19 to 100), respectively. The mean scores for each of the five domains of the EuroQol five-dimension three-level questionnaire were 1.2, 1.0, 1.2, 1.3, and 1.1, and mean overall score 82.6 (50 to 100). Ultrasound showed no pseudotumour. Mean cobalt and chromium levels were 32.1 nmol/l (1 to 374) and 45.5 nmol/l (9 to 408), respectively. Conclusion This study shows that BHRs provide excellent survivorship and functional outcomes in young male patients. At 20 years, soft-tissue imaging and serum metal ion studies suggest that a metal-on-metal resurfacing implant can be well tolerated in a group of young patients.

Ma M, Song P, Zhang S, Kong X, Chai W. Does robot-assisted surgery reduce leg length discrepancy in total hip replacement? Robot-assisted posterior approach versus direct anterior approach and manual posterior approach: a propensity score-matching study. J Orthop Surg Res 2023; 18:445. [PMID: 37344859 PMCID: PMC10286345 DOI: 10.1186/s13018-023-03864-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Accepted: 05/18/2023] [Indexed: 06/23/2023] Open
Abstract
BACKGROUND Advocates of robot-assisted technique argue that robots could improve leg length restoration in total hip replacement. However, there were few studies to compare the robot-assisted posterior approach (RPA) with conventional posterior approach (PA) THA and direct anterior approach (DAA) THA in LLD. This study aimed to determine whether robot-assisted techniques could significantly reduce LLD compared to manual DAA and manual PA. METHODS We retrospectively reviewed the cohort of consecutive ONFH patients who underwent THA robot-assisted posterior, manual posterior, and manual DAA from January 2018 to December 2020 in one institution. One experienced surgeon performed all procedures. We calculated the propensity score to match similar patients in different groups by multivariate logistic regression analysis for each patient. We included confounders consisting of age at the time of surgery, sex, body mass index (BMI), and preoperative LLD. Postoperative LLD and Harris hip scores (HHS) at two years after surgery of different cohorts were compared. RESULT We analyzed 267 ONFH patients treated with RPA, DAA, or PA (73 RPA patients, 99 DAA patients, and 95 PA patients). After propensity score matching, we generated cohorts of 40 patients in DAA and RPA groups. And we found no significant difference in postoperative LLD between RPA and DAA cohorts (4.10 ± 3.50 mm vs 4.60 ± 4.14 mm, p = 0.577) in this study. The HHS at 2 years postoperatively were 87.04 ± 7.06 vs 85.33 ± 8.34 p = 0.202. After propensity score matching, we generated cohorts of 58 patients in manual PA and RPA groups. And there were significant differences in postoperative LLD between the RPA and PA cohorts. (3.98 ± 3.27 mm vs 5.38 ± 3.68 mm, p = 0.031). The HHS at 2 years postoperatively were 89.38 ± 6.81 vs 85.33 ± 8.81 p = 0.019. After propensity score matching, we generated cohorts of 75 patients in manual DAA and PA groups. And there were significant differences in postoperative LLD between the DAA and PA cohorts. (4.03 ± 3.93 mm vs 5.39 ± 3.83 mm, p = 0.031) The HHS at 2 years postoperatively were 89.71 ± 6.18 vs 86.91 ± 7.20 p = 0.012. CONCLUSION This study found no significant difference in postoperative LLD between RPA and DAA, but we found a significant difference between RPA and manual PA, DAA and manual PA in ONFH patients. We found a significant advantage in leg length restoration in primary total hip arthroplasty with robot-assisted surgery.

Arthroplast Today 2023; 20:101118. [PMID: 36938355 PMCID: PMC10015174 DOI: 10.1016/j.artd.2023.101118] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 01/04/2023] [Accepted: 01/29/2023] [Indexed: 03/21/2023] Open
Abstract
Background There are limited reports on the factors affecting the Forgotten Joint Score-12 (FJS-12) in patients after total hip arthroplasty (THA). Therefore, this study aimed to determine whether the quantity and quality of the preoperative psoas muscle are related to the FJS-12 in post-THA patients. Methods This retrospective cohort study used mailed questionnaires and medical records. Questionnaires containing the FJS-12 were mailed to 752 patients who underwent THA at our hospital between April 2015 and August 2020. The quantity and quality of the psoas major muscle were measured by computed tomography. The association between FJS-12 and the quantity and quality of the psoas major muscle was assessed by logistic regression analysis adjusted for potentially relevant factors. Results In total, 484 patients were included in the analysis. The FJS-12 score of the analyzed subjects was 75 points. Poor psoas major muscle quality was associated with a poor group of patients scoring <50 on the FJS-12. This association was independent of the adjustment factors. However, the quantity of psoas muscle was not associated. Conclusions The quality of the psoas major muscle is associated with FJS-12. In the rehabilitation of patients undergoing THA, focusing on the quality of the psoas major muscle may help achieve the ultimate goal.

Does acetabular robotic-assisted total hip arthroplasty with femoral navigation improve clinical outcomes at 1-year post-operative? A case-matched propensity score study comparing 98 robotic-assisted versus 98 manual implantation hip arthroplasties. Orthop Traumatol Surg Res 2023; 109:103477. [PMID: 36375721 DOI: 10.1016/j.otsr.2022.103477] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/24/2021] [Revised: 08/19/2022] [Accepted: 09/02/2022] [Indexed: 11/13/2022]
Abstract
INTRODUCTION Despite the optimization of implant positioning, the clinical benefit of the use of robotic assistance during THA remains uncertain. In this case-control study (robotic versus manual technique) we made a retrospective short-term comparison of: (1) the functional results, (2) the complications, (3) and the influence of radiological symmetrization of the hips on the functional result. HYPOTHESIS The use of a robotic arm improved the functional results of a THA. MATERIALS AND METHOD A retrospective case-control study was performed, including patients with unilateral hip osteoarthritis who underwent a robotic arm-assisted THA (THA-R). The controls (THA-C) were matched according to age, sex, body mass index and surgical approach. The Harris (HHS), Oxford (OHS) and Forgotten Joint (FJS) scores were collected preoperatively and 1 year postoperatively. At each review, complications were categorized into minor events, revision surgery with and without implant change. Radiographic analysis was performed on weight-bearing images of the pelvis 3 months postoperatively. The objective of the surgery was symmetrization of the THA in the contralateral healthy hip. For each measured parameter of the hip joint center of rotation (COR), global offset (GO) and articular leg length discrepancy (aLLD), the difference between the two sides corresponding to the delta symmetrization was compared. RESULTS Ninety-eight patients were included in the THA-R group and matched to 98 controls in the THA-C group. At 1 year postoperatively, the FJS and OHS scores were statistically higher in the THA-R group, respectively 82.1±22.3 [8.3; 100] and 40.8±8.8 [6; 48] vs. 71.2±27.8 [0; 100] and 38.1±9.7 [12; 48] in the THA-C group (p=0.004 and p=0.043). There was no difference in HHS (THA-R: 85.9±15.8 [31; 100] vs. THA-C: 85.8±13.3 [49-100] (p=0.962)). The implant revision rate at 1 year was significantly higher in the THA-C group (0% vs. 5.1% (p=0.025)). There was no difference in the reoperation without component exchange despite 3 dislocations (3.1%) in the THA-R group (5 (5.1%) vs. 9 (9.2%) (p=0.273)). The rate of abarticular pathologies (ilio-psoas irritation and greater trochanteric bursitis) was higher in the THA-C group (10 (10.8%) vs. 2 (2%) (p=0.016). Robotic acetabular assistance allowed a significantly better restitution of the horizontal position (THA-R: 1mm±4.8 [-11.7; 12.6] vs. THA-C: 4.1mm±7 [-29.6; 28] (p=0.0005)) and vertical COR (THA-R: 0.5mm±3.1 [-6; 8.3] vs. THA-C: 2mm±4.1 [-6; 14.6] (p=0.0068)). Navigated assistance of the femur did not significantly optimize the restitution of the Global Offset (THA-R: +2mm±6.4 [-16.4; 27.6] vs. THA-C: +0.5mm±7 .7 [-34; 30.2] (p=0.145)), or lower limb length (THA-R: +1.1mm±5 [-8.2; 13.5] vs. THA-C: +0.3mm±6 [-14.1; 22.5] (p=0.344). The FJS was statistically correlated with the restoration of the symmetry of the COR and the aLLD. A post-hoc power analysis confirmed sufficient potency (1-β=0.85). CONCLUSION Robotic acetabular assistance combined with femoral navigation improves clinical outcomes of THAs with fewer short-term complications. The precision of the positioning of the implants, optimized by the computer-assisted surgery system, is correlated with the missed joint score. LEVEL OF EVIDENCE III, retrospective case-control study.

Abstract
AIMS Although periacetabular osteotomies are widely used for the treatment of symptomatic dysplastic hips, long-term surgical outcomes and patient-reported outcome measures (PROMs) are still unclear. Accordingly, we assessed hip survival and PROMs at 20 years after transpositional osteotomy of the acetabulum (TOA). METHODS A total of 172 hips in 159 patients who underwent TOA were followed up at a mean of 21.02 years (16.6 to 24.6) postoperatively. Kaplan-Meier analysis was used to assess survivorship with an endpoint of total hip arthroplasty (THA). PROMs included the visual analogue scale (VAS) Satisfaction, VAS Pain, Oxford Hip Score (OHS), and Forgotten Joint Score-12 (FJS-12). Thresholds for favourable outcomes for OHS (≥ 42) and FJS-12 (≥ 51) were obtained using the receiver operating characteristic curve with VAS Satisfaction ≥ 50 and VAS Pain < 20 as anchors. RESULTS THA was performed on 37 hips (21.5%) by the latest follow-up. Kaplan-Meier analysis indicated that the hip survival rate at 20 years was 79.7% (95% confidence interval (CI) 73.7 to 86.3). Multivariate analysis showed that preoperative Tönnis grade significantly influenced hip survival. Tönnis grades 0, 1, and 2 were associated with 20-year survival rates of 93.3% (95% CI 84.8 to 100), 86.7% (95% CI 79.8 to 94.3), and 54.8% (95% CI 41.5 to 72.3), respectively. More than 60% of the patients exhibited favourable PROMs. An advanced Tönnis grade at the latest follow-up and a higher BMI were both significantly associated with unfavourable OHS, but not with other PROMs. CONCLUSION This study demonstrated the durability of TOA for hips with Tönnis grades 0 to 1 at 20 years. While the presence of advanced osteoarthritis and higher BMI was associated with lower hip functions (OHS), it was not necessarily associated with worse patient satisfaction and joint awareness.

Maximal Outcome Improvement Willingness Thresholds Are Predictive of a Patient’s Willingness to Undergo the Same Surgery, in Retrospect, Given the Known Outcome of Their Primary Hip Arthroscopy. Arthrosc Sports Med Rehabil 2022; 4:e1007-e1013. [PMID: 35747669 PMCID: PMC9210379 DOI: 10.1016/j.asmr.2022.02.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Accepted: 02/11/2022] [Indexed: 11/26/2022] Open
Abstract
Purpose To determine the percent maximal outcome improvement willingness thresholds (MOWTs) for the Nonarthritic Hip Score (NAHS) and the visual analog scale (VAS) for pain that were associated with a patient’s willingness to undergo surgery, in retrospect, given the known outcome of their primary hip arthroscopy with concomitant endoscopy for gluteus medius (GM) tear repair. Methods An anchor question was provided to patients who underwent primary hip arthroscopy for femoroacetabular impingement syndrome with concomitant endoscopic GM tear repair between April 2008 to April 2020. Patients were included if they answered the anchor question and had baseline and postoperative minimum 1-year follow-up scores for the NAHS and VAS. Patients were excluded if they had a previous ipsilateral hip surgery, Tönnis grade >1, hip dysplasia, previous hip conditions, or a preoperative score that was already at the maximum value for the NAHS and VAS scores. Receiver operating characteristic (ROC) analysis was used to determine the MOWT. Significance was indicated by a P value <.05. Results A total of 107 patients (107 hips) were included, with 101 (94.4%) females and 6 (5.6%) males. The average age and body mass index was 56.20 ± 9.88 years and 28.80 ± 4.92 kg/m2, respectively. The average follow-up time was 54.89 ± 29.52 months. The ROC analysis determined that the MOWT for the mHHS and VAS were 54.7%, and 62.6%, respectively. The probability of a patient being willing to undergo surgery again if they met the MOWT was 85.8% and 85.6% for the NAHS and VAS, respectively. Conclusion The MOWTs that were predictive of willingness to undergo surgery again following primary hip arthroscopy with concomitant endoscopy for GM tear repair were 54.7% and 62.6% for the NAHS, and VAS, respectively. Clinical Relevance Outcome assessment has been a point of increasing emphasis in hip preservation surgery. Having a tool to measure whether patients would go through the process of surgery again knowing their current outcome status is important to understanding outcomes after surgery.

Abstract
Background Aseptic loosening is among the most common reasons for revision total hip arthroplasty (RTHA). Modular revision stems implanted through an extended trochanteric osteotomy (ETO) promise good results, but patient-reported outcome measures (PROMs) are rarely conveyed. This study used the Forgotten Joint Score-12 (FJS-12) to assess patient-reported outcome in patients who had undergone RTHA for aseptic stem loosening using a modified ETO approach with a tapered, fluted modular stem. Material and methods A single-center analysis of aseptic RTHA was performed (2007–2019). Clinical results (range of motion, walking ability, function), radiographic results (ETO healing, stem subsidence), and PROMs (FJS-12, Harris Hip Score, European Quality of Life 5D Score) were assessed. Minimum follow-up duration was 1 year. Complications including revisions were recorded. Results Primary outcome parameters were assessed on 72 patients (mean age 73.3 years, mean body mass index 27.6kg/m2). Additional PROMs were collected by phone interviews from 41 patients (mean follow-up 5.7 years). In 76%, leg length was restored, and a normal gait was achieved. After 1 year, the ETO was healed in 93%; subsidence occurred in 8.3% of cases. The mean FJS-12 at the final follow-up was 85.6 ± 23.6, and the respective Harris Hip Score and European Quality of Life 5D Score averaged 87 ± 17.8 and 72.9 ± 15.9. Complication and revision rates were 33.3% and 13.9%, respectively. Conclusion Aseptic RTHA as presented here resulted in excellent PROMs in the medium term. FJS-12 score averaged 85.6 with a mean follow-up of 5.7 years. Treatment using a modular implant and a modified ETO was associated with good clinical and radiographic outcomes. Complication and revision rates were 33.3% and 13.9%, respectively.

Abstract
AIMS The Forgotten Joint Score-12 (FJS-12) is a validated patient-reported outcome measure (PROM) tool designed to assess artificial prosthesis awareness during daily activities following total hip arthroplasty (THA). The patient-acceptable symptom state (PASS) is the minimum cut-off value that corresponds to a patient's satisfactory state-of-health. Despite the validity and reliability of the FJS-12 having been previously demonstrated, the PASS has yet to be clearly defined. This study aims to define the PASS of the FJS-12 following primary THA. METHODS We retrospectively reviewed all patients who underwent primary elective THA from 2019 to 2020, and answered both the FJS-12 and the Hip Disability and Osteoarthritis Outcome Score, Joint Replacement (HOOS, JR) questionnaires one-year postoperatively. HOOS, JR score was used as the anchor to estimate the PASS of FJS-12. Two statistical methods were employed: the receiver operating characteristic (ROC) curve point, which maximized the Youden index; and 75th percentile of the cumulative percentage curve of patients who had the HOOS, JR score difference larger than the cut-off value. RESULTS This study included 780 patients. The mean one-year FJS-12 score was 65.42 (SD 28.59). The mean one-year HOOS, JR score was 82.70 (SD 16.57). A high positive correlation between FJS-12 and HOOS, JR was found (r = 0.74; p<0.001), making the HOOS, JR a valid external anchor. The threshold score of the FJS-12 that maximized the sensitivity and specificity for detecting a PASS was 66.68 (area under the curve = 0.8). The cut-off score value computed with the 75th percentile approach was 92.20. CONCLUSION The PASS threshold for the FJS-12 at one year following primary THA was 66.68 and 92.20 using the ROC curve and 75th percentile approaches, respectively. These values can be used to achieve consensus about meaningful postoperative improvement to maximize the utility of the FJS-12 to evaluate and counsel patients undergoing THA.

Abstract
In orthopaedics, patient reported outcomes (PROMs) are designed to quantify changes in pain and to assess physical function, most often after joint arthroplasty. However, PROMs have some disadvantages, most important is their subjective nature. The aim was to investigate how patient-self-reported-outcomes of general health, disease-specific outcome and physical function, joint-awareness and self-perceived activity- levels are correlated with objectively-measured physical-activity (PA) parameters derived from wearable activity-monitors (AM) in subjects with a hip-arthroplasty. A prospective cohort study was conducted in a group of 32 patients, with a mean follow-up of 10 years after total hip arthroplasty. To assess different domains, the SF-36 (general health), HOOS-PS (pain/functional outcome), FJS-12 (joint awareness) and SQUASH (physical activity) were chosen. Activity-monitoring was performed using a 3-axis accelerometer, gyroscope and magnetometer. No significant correlations between PA-parameters and the FJS-12 and SQUASH were found. The HOOS- PS was significant correlated with BMI, the daily time walking and total-time active and the amount of daily steps. The physical functioning-subscale of the SF-36 was significant negative correlated with BMI and time sitting, but significant positive correlated with time walking, total-time active and the amount of daily steps. Considering the value of PA for maintaining general health, the value of using sensor-based AMs to assess efficacy of treatments in this health related dimension or use it as a tool for patient education, awareness and communication, seems very high.

Abstract
Background/Purpose The purpose of this study was to compare the joint awareness and knee function after unicompartmental knee arthroplasty (UKA) and total knee arthroplasty (TKA) for the management of isolated medial compartment osteoarthritis. Methods Patients who underwent UKA or TKA at our institution for isolated medial compartment osteoarthritis from 2015 to 2020 with a minimum follow-up of 1 year were screened. 116 eligible patients were invited and 94 volunteer patients participated. All patients were evaluated with The Forgotten Joint Score-12 and Lysholm Knee Scale. Results Average follow-up period was 29.13±15.48 months for UKA and 31.66±2.91 months for TKA groups ( p=0.292). FJS-12 of the UKA group was significantly higher than that of the TKA group (79.74±15.06 and 63.25±19.86, respectively; p=0.024). The Lysholm Knee Scale score was also significantly higher in the UKA group compared with the TKA group (92.94±8.74 and 78.34±14.99, respectively; p = 0.002). Conclusion Our findings suggest that patients who underwent UKA were less aware of their artificial joints and had better knee function compared to patients who underwent TKA for medial osteoarthritis of the knee.

Abstract
Gluteus medius (GM) tears are currently a well-established source of pain and disability. However, their role in primary total hip arthroplasty (THA) in the setting of osteoarthritis (OA) has been underexamined in the literature. The purpose of this study was to report on short-term patient-reported outcome measurements (PROMs) for patients who underwent concomitant primary THA and GM repair. Data were prospectively collected from September 2011 and June 2017. Inclusion criteria were primary THA along with concomitant GM repair and complete follow-up for the Harris Hip Score, Forgotten Joint Score 12, Veterans RAND 12-item Health Survey both Physical and Mental, 12-item Short Form Survey both Physical and Mental (SF-12 P and SF-12 M), visual analog scale for pain, and patient satisfaction. Patients were excluded if they did not have follow-up. Thirty patients (30 hips) were included. Mean follow-up was 24.2±19.3 months. Twenty-nine (96.7%) patients were female. Mean age was 65.2±7.4 years. Mean body mass index was 31.1±5.9 kg/m2. The posterior approach was used for 16 (53.3%) cases and the anterior approach for the remaining 14 (46.7%). Two (6.7%) patients had a less than 25% tear, 7 (23.3%) had a 25% to 50% tear, 14 (46.7%) had a greater than 50% tear, and 7 (23.3%) had a full-thickness tear. All PROMs except SF-12 M demonstrated significant improvement at latest follow-up. Patients who underwent THA with either the anterior or the posterior approach with concomitant GM repair using modern suture anchor techniques reported favorable PROMs at short-term follow-up.

Determining Clinically Meaningful Thresholds for the Nonarthritic Hip Score in Patients Undergoing Arthroscopy for Femoroacetabular Impingement Syndrome. Arthroscopy 2021; 37:3113-3121. [PMID: 33865933 DOI: 10.1016/j.arthro.2021.03.059] [Citation(s) in RCA: 31] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2020] [Revised: 03/23/2021] [Accepted: 03/29/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE The purpose of this study was to improve the interpretability of the Nonarthritic Hip Score (NAHS) by determining the minimal clinically important difference (MCID), patient acceptable symptomatic state (PASS), and substantial clinical benefit (SCB) after hip arthroscopy for femoroacetabular impingement. The secondary aim was to identify variables associated with achievement of the thresholds. METHODS Patients who underwent hip arthroscopy for femoroacetabular impingement and completed postoperative questionnaires between August 2019 and March 2020 were included. Patients were excluded if they underwent previous ipsilateral hip surgery, underwent gluteus medius repair, or had a previous hip condition. The MCID, PASS, and SCB thresholds were calculated for the NAHS at minimum 1-, 2-, and 5-year follow-up. Distribution- and anchor-based methods with receiver operating characteristic analysis were used to determine the thresholds. Multivariate logistic regression was performed to determine predictors of achieving the MCID and PASS. RESULTS The study included 343 hips with an average follow-up period of 48 months. On the basis of the distribution-based approach, the MCID was 8.7 using a method in which the standard deviation of the baseline score was divided by 2. By use of a method in which the standard deviation of the change score was divided by 2, MCID scores of 9.1, 8.3, and 12.6 resulted at a minimum of 1, 2, and 5 years, respectively. The PASS thresholds for these time points were 81.9, 85.6, and 81.9. The absolute SCB thresholds were 91.9, 94.4, and 93.1 and the change score thresholds were 30.6, 24.4, and 29.3 for a minimum of 1, 2, and 5 years, respectively. The preoperative NAHS was positively associated with achievement of the PASS and inversely related to achievement of the MCID. CONCLUSIONS This study provides important clinical thresholds for the NAHS. These thresholds were determined for minimum 1-, 2-, and 5-year time points. The MCID was determined as 8.7, the PASS ranged between 81.9 and 85.6, and the absolute SCB value ranged from 91.9 to 94.4. The preoperative NAHS was found to be positively associated with achievement of the PASS and inversely related to achievement of the MCID. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
The aim of this study was to report patient-reported outcome measurements in a large group of patients who underwent robotic-arm assisted primary total hip arthroplasty (THA). Prospectively collected data were retrospectively reviewed between April 2012 and May 2017. Primary THAs using the Mako robotic-arm assisted (Mako Surgical Corp [Stryker]) with minimum 2-year follow-up for Harris Hip Score (HHS) and Forgotten Joint Score-12 (FJS-12) were included. Exclusion criteria were body mass index (BMI) of 40 kg/m2 or greater, age younger than 21 years, workers' compensation, or unwillingness to participate. Visual analog scale (VAS) score for pain and patient satisfaction score were obtained. Intraoperative measurements for leg length, global offset, acetabular inclination, and version were documented. A total of 501 hips were included, with 57.29% of the patients being female. Mean follow-up was 43.99±15.59 months. Mean age was 58.70±9.41 years. Mean BMI was 28.41±4.55 kg/m2. Mean HHS was 90.87±13.45, mean FJS-12 was 79.97±25.87, mean VAS score was 1.20±2.06, and mean patient satisfaction score was 8.85±2.08. Intraoperative values for acetabular inclination and version were 40.0°±2.2° and 20.5°±2.4°, respectively. The rate of revision due to instability was 0.2%. Patients who received primary robotic-arm assisted THA reported excellent results at 44-month follow-up for multiple patient-reported outcome measurements. Consistency in acetabular cup placement accuracy was achieved regarding the Lewinnek and Callanan safe zones. [Orthopedics. 2021;44(2):70-76.].

Abstract
BACKGROUND Obesity is a growing public health concern. This study aims to identify the association of body mass index (BMI) on postoperative Forgotten Joint Score-12 (FJS-12) in patients undergoing primary total hip arthroplasty (THA). METHODS We retrospectively reviewed 2130 patients at a single urban, academic, tertiary institution who underwent primary THA from 2016-2020 with available postoperative FJS-12 scores. Patients were stratified into two groups based on their BMI (kg/m2):<30 (nonobese) and ≥30 (obese). FJS-12 scores were collected postoperatively at 3 months, 1 year, and 2 years. Demographic differences were assessed with chi-square and independent sample t-tests. Mean scores between the groups were compared using multilinear regression analysis, controlling for demographic differences. RESULTS Of the 2130 patients included, 1378 were nonobese, and 752 were obese. Although obese patients reported lower FJS-12 scores all time periods, there were no statistical differences between the two groups at 3 months (53.61 vs 49.62;P = .689), 1 year (68.11 vs 62.45; P = .349), and 2 years (73.60 vs 65.58; P = .102). A subanalysis comparing patients who were of normal BMI (<25), overweight (25.0-29.9), and obese (≥30) followed a similar inverse trend in scores but showed no statistical differences at all postoperative time points (3m:P = .612,1y:P = .607,2y:P = .253). Mean improvement in FJS-12 scores from 3 months to 1 year (14.50 vs 12.83; P = .041), 1 year to 2 years (5.49 vs 3.13; P = .004), and from 3 months to 2 years (20.00 vs15.96; P < .001) were significantly greater for nonobese patients compared to obese patients. CONCLUSION While obesity trended toward lower FJS-12 scores, the differences in scores were not statistically significant compared to nonobese patients. BMI did not influence overall FJS-12 scores; however, obese patients achieved a slightly smaller statistical improvement during the first 2 years, though this may not be clinically significant.

Abstract
Background Although a successful operation, almost 20% of patients are dissatisfied with total knee arthroplasty (TKA). The purpose of this retrospective cohort study was to see if a medial congruent (MC) polyethylene would offer satisfactory early outcomes and patient satisfaction after TKA. Methods We reviewed prospectively collected data on 327 TKAs using multiple bearings within the same implant system. Ninety-six received an MC bearing, 70 received a cruciate-retaining (CR) bearing, and 161 received a posterior-stabilized (PS) bearing. We evaluated the visual analog scale pain scores and range of motion (ROM) at 2 weeks, 6 weeks, 3 months, and 1 year; Patient-Reported Outcomes Measurement Information System (PROMIS-10) score and Knee Injury and Osteoarthritis Outcome Score (KOOS) at 3 months and 1 year; and Forgotten Joint Score (FJS-12) at 1 year. Results All groups had similar KOOS and PROMIS-10 scores. MC knees had lower visual analog scale scores than PS knees at all time points (P < .05) and a higher ROM than PS at 2 weeks (98.6 vs 93.7, P = .002). MC knees had a significantly higher FJS-12 than CR knees (71.6 vs 58.7, P = .02). More MC knees were “very satisfied” than CR (92.6% vs 81.5%, P = .04). Fewer MC knees were “not at all satisfied” than CR (1.2% vs 9.2%, P = .04). There were similar satisfaction ratings with MC and PS. Conclusions An MC bearing provided similar or improved early pain, ROM, KOOS, PROMIS-10, FJS-12, and patient satisfaction as compared with standard bearings in TKA.

Abstract
When it comes to total hip replacements, choosing the suitable material combination is of clinical relevance. The present review article examines the technical differences in wear and corrosion of the relevant material combinations of ceramics, metals, ceramized metals and various types of polyethylene. The material characteristics, which were often tested under standardized conditions in the laboratory, are compared with clinical results on the basis of evidence-graded clinical studies and on the basis of register studies. This article thus represents an up-to-date snapshot of the expectations and actual clinical outcomes of the present choice of material combinations. It shows that some tendencies from the field of materials research, e.g. with regard to cross-linked polyethylene, coincide with observations from practical clinical experience, while for other materials, a proven technical superiority has not yet been confirmed as an evident advantage in clinical practice.

Total Hip Arthroplasty: Minimal Clinically Important Difference and Patient Acceptable Symptom State for the Forgotten Joint Score 12. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18052267. [PMID: 33668868 PMCID: PMC7956707 DOI: 10.3390/ijerph18052267] [Citation(s) in RCA: 26] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/17/2021] [Revised: 02/15/2021] [Accepted: 02/19/2021] [Indexed: 12/19/2022]
Abstract
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.

Abstract
BACKGROUND The purpose of this study is to compare outcomes after total hip arthroplasty (THA) in patients with preoperative asymptomatic gluteus medius and minimus (GMM) pathology to a control group with no GMM pathology. METHODS Patients undergoing THA for osteoarthritis between August 2012 and March 2018 were retrospectively reviewed. Asymptomatic GMM pathology was considered as the presence of gluteal tendinopathy diagnosed by magnetic resonance imaging (MRI) without the following clinical symptoms: Trendelenburg gait or test, abductor weakness, and lateral thigh tenderness. Patients with asymptomatic GMM pathology were matched (1:1) to patients without GMM pathology on MRI. Two-year data were collected on patient-reported outcomes including Harris Hip Score, Forgotten Joint Score, pain, and satisfaction. Postoperative clinical examination, radiographic measures, complications, and revisions for both groups were reviewed. RESULTS Fifty cases of asymptomatic GMM pathology were successfully matched to 50 hips without GMM pathology on MRI. Patients with asymptomatic GMM pathology demonstrated significantly worse outcomes regarding 2-year Harris Hip Score (86.24 vs 92.39, P = .04), VAS for pain (1.82 vs 0.98, P = .05), and patient satisfaction (7.69 vs 9.16, P = .002). The study group exhibited significantly higher rates of lateral hip pain postoperatively. Two cases (4%) in the control group underwent a revision THA and 4 cases (8%) in the study group underwent revision THA. CONCLUSION In patients undergoing THA for osteoarthritis, those with asymptomatic GMM pathology experience inferior 2-year postoperative patient-reported outcomes compared to a matched group. This finding should raise awareness surrounding this important pathology's negative impact on surgical outcomes, thus warranting increased vigilance, and possibly justifying concomitant treatment, even in cases of asymptomatic GMM tears.

Abstract
Background Leg length discrepancy (LLD) after total hip arthroplasty (THA) is a known source of complications and a leading cause of litigation (J Bone Joint Surg Br 87:155–157, 2005). There are limited studies investigating surgical approach combined with the use of fluoroscopy intraoperatively and their potential effects on LLD after THA. The purpose of this study was to compare the direct anterior (DA) approach utilizing a fluoroscopic overlay technique and anterolateral (AL) approach and their potential effect on LLD. Methods We retrospectively reviewed 121 patients who had undergone primary THA from September 1, 2016 to November 1, 2018 by either DA or AL approach by two separate surgeons. Leg length discrepancies were measured on pre-operative post-anesthesia care unit (PACU) and on post-operative low anterior/posterior (AP) pelvis plain radiographs by two investigators blinded to each other’s measurements. To confirm inter-observer and intra-observer reliability between LLD measurements amongst investigators, a Pearson correlation test was performed. The primary outcome measurement was leg length discrepancy (LLD). Results We observed LLD > 1.0 cm and LLD > 1.5 cm in the DA and AL groups. The DA approach group showed a mean LLD of 4.5 mm against 7.76 mm in the AL group (p < 0.00001). There was a significantly higher rate of LLD in the AL group as compared to the DA group (LLD> 1 cm (28% vs. 8%, p = 0.0037) and LLD > 1.5 cm (7% vs. 0%, p = 0.0096). The LLD measurements showed strong correlation in terms of inter-observer (r = 0.95) and intra-observer reliability (r = 0.99) between the two investigators (p < 0.001). Conclusion In our patient cohort, the DA approach with fluoroscopic overlay technique had less LLD in comparison with the AL approach, suggesting that intraoperative fluoroscopic use does have an impact on LLD.

Abstract
BACKGROUND Frequently, patients with hip complaints also report lower back pain, and elective surgery may be indicated due to end-stage hip osteoarthritis and degenerative disc disease. Thus, we aim to answer the question of whether total hip arthroplasty (THA) or lumbar spine surgery should be performed first in patients with hip-spine-syndrome, from an arthroplasty surgeon's point of view. DECISION-MAKING The present review demonstrates that in patients with an acute neurological deficit, lumbar spine surgery should be performed first. However, in patients without these symptoms, several arguments favour performing THA first, especially the increased risk of dislocation when performing THA after lumbar spine fusion (LSF) in comparison to "THA first" (4.6 vs. 1.7% after 2 years; p < 0,001). However, the risk of dislocation after THA remains increased in both scenarios, independent of surgical order. Consequently, arthroplasty surgeons should pay great attention to optimum component positioning, reconstruction of the hip anatomy, leg length and soft-tissue tension, while considering using large prosthesis heads or dual mobility cups when performing primary THA in patients with an increased risk of dislocation. In complex cases, we would encourage arthroplasty and spine surgeons working in cooperation on highly individual treatment concepts.

[PMID: 32867794 PMCID: PMC7457487 DOI: 10.1186/s13018-020-01871-8] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2020] [Accepted: 08/07/2020] [Indexed: 01/03/2023] Open
Abstract
BACKGROUND The transition to outpatient-based surgery is a major development occurring in recent years in the field of total hip arthroplasty (THA). The effect of this transition on patient-reported outcomes (PROs) is still not well established. The purpose of the current study was to compare patients undergoing inpatient THA (iTHA) to patients undergoing outpatient THA (oTHA) regarding (1) perioperative variables including surgical time, blood loss, and length of stay (2) 90-day complication rates and unplanned emergency room or office visits (3) 2-year PROs including modified Harris hip score (mHHS), Harris hip score (HHS), forgotten joint score (FJS), pain, and satisfaction, as well as the quality of live measures. METHODS The American Hip Institute registry was analyzed for patients undergoing THA between July 2014 and April 2016. The first 100 patients undergoing oTHA were selected and matched to 100 patients undergoing iTHA via propensity matching based on the following variables: age, sex, body mass index (BMI), Charlson comorbidity index (CCI), and smoking status. The primary outcomes were PROs at 2 years post-operatively. The secondary outcomes were perioperative surgical variables, 90-day complication rates, and unplanned emergency and clinic visits. RESULTS After exclusions, 91 patients remained in each group and were compared. The oTHA group showed improved 2-year PROs with regard to mHHS (91.5 vs. 86.2; P = 0.02), HHS (92.3 vs. 87.4; P = 0.02), and pain (1.0 vs. 1.5; P = 0.04). The oTHA group had an average length of stay of 6.8 h compared to 43.2 h for the iTHA group (P < 0.001). There were no significant differences between the groups regarding readmissions, emergency room visits, and unplanned clinic visits. Complications and revision rates were similar in both groups. CONCLUSION In appropriately selected, younger patients, oTHA can achieve improved postoperative 2-year PROs compared to iTHA. We found no differences regarding postoperative short-term complications or 2-year revision rates, and no differences in unplanned office visits or readmissions. LEVEL OF EVIDENCE Prognostic level 3.

Patient-acceptable symptom state for the Oxford Hip Score and Forgotten Joint Score at 3 months, 1 year, and 2 years following total hip arthroplasty: a registry-based study of 597 cases. Acta Orthop 2020; 91:372-377.

Abstract
Background and purpose - Patient-acceptable symptom states (PASS) represent the level on a patient-reported outcome measure (PROM) at which patients are satisfied with postoperative outcomes. We defined the PASS for the Oxford Hip Score (OHS) and Forgotten Joint Score (FJS-12) at 3-month, 1-year, and 2-year intervals after primary total hip arthroplasty (THA).Patients and methods - Between July 2018 and April 2019, primary THA patients in an academic medical center's registry completed the OHS, FJS-12, and a satisfaction anchor question at 3-month (n = 230), 1-year (n = 180), or 2-year (n = 187) postoperative intervals. PASS thresholds were derived with receiver operating characteristic analysis using the 80% specificity method. 95% confidence intervals (CI) were calculated using 1,000 non-parametric bootstrap replications.Results - 74%, 85%, and 86% of patients reported having a satisfactory symptom state at 3 months, 1, and 2 years after surgery, respectively. At 3-month, 1-year, and 2-year intervals, PASS thresholds were 34 (CI 31-36), 40 (CI 36-44), and 39 (CI 35-42) points for the OHS and 59 (CI 54-64), 68 (CI 61-75), and 69 (CI 62-75) points for the FJS-12.Interpretation - PASS thresholds varied with time for both the OHS and the FJS-12, with lower 3-month compared with 1-year and 2-year thresholds. These PASS thresholds represent OHS and FJS-12 levels at which the average patient is satisfied with THA outcomes, helping to interpret PROMs and serving as clinically significant benchmarks and patient-centered outcomes for research.

[PMID: 32563416 DOI: 10.1016/j.knee.2020.04.014] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2020] [Revised: 04/03/2020] [Accepted: 04/06/2020] [Indexed: 02/05/2023]
Abstract
BACKGROUND In this clinical investigation, a new design with a progressive increased keel medialization according to the size was implanted. The cohort of patients was followed up for seven years. METHODS From May 2012 to November 2012, we implanted 70 total knee arthroplasties in 69 patients. The mean age of the patients was 76.2 years. We followed up 56 patients for seven years; we evaluated the patients at six and 60 months after surgery by Patient Reported Outcome Measures score. During the seven-year follow-up, all patients were clinically re-evaluated using the Knee Society Score and the Forgotten Joint Score. All patients underwent a preoperative and postoperative radiographic investigation. At the last follow-up the presence of any radiolucency lines was checked using the Knee Society Total Knee Arthroplasty Radiographic Evaluation and Scoring System. RESULTS The patients defined the surgical results as excellent in 66% of the cases, very good in 23%, good in five percent. The analysis of the functional data at seven years, performed by administering the Forgotten Joint Score, showed average values of 70.4. The clinical analysis, performed through the Knee Society Score at the same follow-up, showed average values of 90.4. The seven-year radiological analysis revealed the presence of radiolucency lines in 20 implants. The sum of the line widths never exceeded the critical value of nine millimeters, always remaining below four millimeters. Only one patient was revised. CONCLUSIONS The results showed an excellent outcome of this design. The medialization of the tibial keel showed good bone fixation and component alignment at seven-year follow-up.

Abstract
BACKGROUND Objective of the study was to evaluate and compare psychometric properties such as validity, reliability, floor ceiling effects and interpretability of the modified Harris Hip Score (mHHS) and the Forgotten Joint Score (FJS) in patients undergoing bipolar hemiarthroplasty for femoral neck fracture in Indian patients, because this has not been done before. METHODS This observational study consisted of 40 consecutively operated patients. Construct validity and reliability were evaluated using correlation coefficient and Intraclass correlation coefficient (ICC), respectively. Interpretability was evaluated by describing mean and standard deviation of mHHS and FJS in five subgroups of patients based on their response to the global rating questions and assessment. RESULTS The mean follow-up duration was 15.7 months ± 10.4. There was very high correlation between mHHS and FJS (r = 0.92, p < 0.0001) suggesting convergent construct validity. The results of correlation coefficient were 100% and 66.7% in accordance with the pre-formulated hypotheses for mHHS and FJS, respectively. mHHS and FJS demonstrated adequate construct validity and inadequate construct validity, respectively. The ICC value for mHHS and FJS was 0.80 (p = 0.005) {adequate reliability} and 0.34 (p = 0.06) {inadequate reliability}, respectively. Both mHHS and FJS-12 demonstrated acceptable level of floor (0% for mHHS and 14.3% for FJS) and ceiling effects (12.5% for both mHHS and FJS). There was significant difference in the mHHS and FJS in the five subgroups of patients suggesting adequate interpretability. CONCLUSION We recommend the use of the modified Harris Hip Score over the Forgotten Joint Score for functional outcome evaluation of Indian patients from rural setting undergoing bipolar hemiarthroplasty for femoral neck fracture.
