Expansion of HLA-DR Positive Peripheral Helper T and Naive B Cells in Anticitrullinated Protein Antibody-Positive Individuals At Risk for Rheumatoid Arthritis.

OBJECTIVE: To investigate immune dysregulation in the peripheral blood that contributes to the pre-rheumatoid arthritis (RA) stage of RA development in anticitrullinated protein antibody (ACPA)+ individuals. METHODS: Using 37 markers by mass cytometry, we investigated peripheral blood mononuclear cells (PBMCs) from ACPA+ at-risk individuals, ACPA+ early untreated patients with RA, and ACPA- controls in the Tokyo Women's Medical University cohort (n = 17 in each group). Computational algorithms, FlowSOM and Optimized t-Distributed Stochastic Neighbor Embedding, were employed to explore specific immunologic differences between study groups. These findings were further evaluated, and longitudinal changes were explored, using flow cytometry and PBMCs from the US-based Targeting Immune Responses for Prevention of RA cohort that included 11 ACPA+ individuals who later developed RA (pre-RA), of which 9 had post-RA diagnosis PBMCs (post-RA), and 11 ACPA- controls. RESULTS: HLA-DR+ peripheral helper T (Tph) cells, activated regulatory T cells, PD-1hi CD8+ T cells, and CXCR5-CD11c-CD38+ naive B cells were significantly expanded in PBMCs from at-risk individuals and patients with early RA from the Tokyo Women's Medical University cohort. Expansion of HLA-DR+ Tph cells and CXCR5-CD11c-CD38+ naive B cells was likewise found in both pre-RA and post-RA time points in the Targeting Immune Responses for Prevention of RA cohort. CONCLUSION: The expansion of HLA-DR+ Tph cells and CXCR5-CD11c-CD38+ naive B cells in ACPA+ individuals, including those who developed inflammatory arthritis and classified RA, supports a key role of these cells in transition from pre-RA to classified RA. These findings may identify a new mechanistic target for treatment and prevention in RA.

Long-Term Implant Fracture Rates Following Silicone Metacarpophalangeal Joint Arthroplasty in Rheumatoid Arthritis.

PURPOSE: The primary objective of this study was to compare the long-term survival rates of silicone metacarpophalangeal (MCP) arthroplasties between two major implants in patients with rheumatoid arthritis, using implant fracture as an end point. We also evaluated the difference in postoperative function between patients with fractured and intact implants as a secondary objective. METHODS: A retrospective cohort study was conducted on 372 fingers of 133 hands that underwent silicone MCP arthroplasty between January 2000 and June 2019 (mean follow-up, 7.6 years). The survival rates of Swanson-type and Sutter-type implants were compared, using implant fracture as the end point after a radiographic evaluation. Clinical measures and upper limb functional assessments using the Disabilities of the Arm, Shoulder, and Hand (DASH) score were performed in the nested cohort. RESULTS: The 10.6-year survival rates for implant fracture of Swanson- and Sutter-type implants were 86.2% and 9.4%, respectively, with significantly higher survival noted for Swanson-type implants. The Sutter-type implant showed increased susceptibility to fracture in all four fingers compared to the Swanson-type implant. Implant fractures were primarily observed at the stem-hinge junction. There were no significant differences in upper limb function between the fractured and intact implant groups. CONCLUSIONS: Sutter-type implants were found to be more prone to fracture compared with Swanson-type implants. However, implant fractures did not significantly affect upper limb function. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognosis IV.

Outcomes of Joint-Preserving Surgery for Forefoot Deformities in Patients With Rheumatoid Arthritis.

BACKGROUND: With the advent of effective disease-modifying medications, the surgical treatment of forefoot deformities in patients with rheumatoid arthritis (RA) has evolved from joint-sacrificing to joint-preserving surgery. However, it is unclear whether joint-preserving surgery is effective for the full range of metatarsophalangeal joint involvement. Hence, this study investigated the postoperative outcomes of joint-preserving surgery for rheumatoid forefoot deformities with a wide range of joint destruction. METHODS: This retrospective observational study included 68 feet from 68 patients with RA who underwent joint-preserving surgery for forefoot deformities between 2014 and 2020. The Larsen grade classification was used to assess the first metatarsophalangeal joint destruction and classify patients into 4 groups as follows: 0 and 1 (n = 14), 2 (n = 21), 3 (n = 19), and 4 and 5 (n = 14). The Self-Administered Foot and Ankle Evaluation Questionnaire (SAFE-Q) score, hallux valgus angle (HVA), and intermetatarsal angle (IMA) were determined before surgery and at the last follow-up visit. RESULTS: The median observation duration was 40 (range, 24-78) months. SAFE-Q scores of all groups significantly improved in all subscales at the last observation, with no significant differences among the study groups. Radiographic evaluations of all groups revealed significant improvements in HVA and IMA after surgery, with no significant differences among the groups. CONCLUSION: In patients using the surgical approaches described in this study, joint-preserving surgery for rheumatoid forefoot deformities led to satisfactory clinical and radiographic improvements, regardless of the severity of joint destruction. LEVEL OF EVIDENCE: Level III, case-control study.

Impact of interstitial lung disease on clinical remission and unfavourable events of rheumatoid arthritis: results from the IORRA cohort.

OBJECTIVES: We aimed to examine the impact of concomitant interstitial lung disease (ILD) on achieving clinical remission and the occurrence of unfavourable clinical events in patients with RA. METHODS: Among the participants in the Institute of Rheumatology, Rheumatoid Arthritis (IORRA) cohort from 2011 to 2012, patients not achieving remission of 28-joint disease activity score (DAS28) at baseline and those with chest CT images were enrolled. Based on the chest CT images, the patients were divided into two groups: the ILD group and non-ILD group. The associations among the presence of ILD with time to achieving DAS28 remission and development of death, hospitalized infection, major adverse cardiac events (MACE), or malignancy within 5 years were evaluated using time-dependent Cox regression models. RESULTS: We enrolled 287 patients in the ILD group and 1235 in the non-ILD group. DAS28 remission was achieved at least once in 55.7% and 75.0% of the ILD and non-ILD groups within 5 years, respectively. Presence of ILD was significantly associated with failure to achieve DAS28 remission (adjusted hazard ratio [aHR]: 0.71; 95% CI: 0.58, 0.89). ILD was also a significant factor associated with death (aHR: 3.24; 95% CI: 2.08, 5.03), hospitalized infection (aHR 2.60; 95% CI: 1.77, 3.83), MACE (aHR: 3.40; 95% CI: 1.76, 6.58), and lung cancer (aHR: 16.0; 95% CI: 3.22, 79.2), but not with malignant lymphoma (aHR: 2.27; 95% CI: 0.59, 8.81). CONCLUSION: Concomitant ILD was a significant factor associated with failure to achieve clinical remission and the occurrence of the unfavourable clinical events in patients with RA.

Combination treatment with Janus kinase inhibitor and nintedanib for rheumatoid arthritis with progressive interstitial lung disease: A case report.

Interstitial lung disease (ILD) is a common extra-articular manifestation of rheumatoid arthritis (RA). Nintedanib has been approved for the treatment of idiopathic pulmonary fibrosis. Herein, we described the case of an 87-year-old woman treated with Janus kinase inhibitor (JAKi). Chest computed tomography revealed increased honeycombing; she was administered nintedanib while continuing RA treatment. The combination treatment (JAKi and nintedanib) controlled the RA disease activity without ILD deterioration. This case shows the potential of combination treatment with JAKi and nintedanib for the prevention of worsening of disease activity in RA and ILD.

Smoking, Serum Albumin and 25-hydroxy Vitamin D Levels, and Bone Mineral Density Are Associated with Tooth Loss in Patients with Rheumatoid Arthritis.

Objectives This study investigated factors associated with tooth loss in patients with rheumatoid arthritis (RA). Methods A total of 429 patients with RA were enrolled in the study. We examined tooth loss and clinical data. Patients were classified into two groups: a group with tooth loss (tooth loss-positive group), and a group without tooth loss (tooth loss-negative group). Patients were included in the tooth loss-positive group if they had fewer remaining teeth than the number defined by the Ministry of Health, Labour and Welfare in Japan to be the normal number teeth for that age and sex. Factors associated with tooth loss were analyzed by comparing the tooth loss-positive and loss-negative groups. Results The frequency of patients with tooth loss was 39.6%. The factors associated with tooth loss were smoking [odds ratio (OR) 1.638; 95% confidence interval (CI) 1.165-2.302], serum levels of albumin (OR 0.325; 95% CI 0.149-0.707) and 25-hydroxy vitamin D (OR 0.947; 95% CI 0.915-0.980), and total hip T score (OR 0.713; 95% CI 0.535-0.950). Conclusion This study revealed that tooth loss is associated with smoking, serum levels of albumin and 25-hydroxy vitamin D, and the total hip T score in patients with RA. Our findings may help prevent tooth loss in patients with RA.

Trends in risks of malignancies in Japanese patients with rheumatoid arthritis: Analyses from a 14-year observation of the IORRA cohort.

OBJECTIVES: The aim is to investigate the trends in risks of overall and site-specific malignancies in patients with rheumatoid arthritis (RA). METHODS: Among Japanese patients with RA enrolled in the Institute of Rheumatology, Rheumatoid Arthritis cohort, all malignancies that occurred from 2000 to 2013 were extracted. The standardized incidence ratios and 95% confidence intervals for overall and site-specific malignancies were calculated during three periods: pre-biologics, 2000-04; early biologics, 2005-09; and recent biologics, 2010-13. Risk factors for overall and specific malignancies were analysed using time-dependent Cox regression models. RESULTS: Among 11,299 patients with RA (68,483 person-years), 507 malignancies were confirmed. Similar risks were observed versus the general Japanese population for overall malignancies throughout the three periods, with standardized incidence ratios (95% confidence intervals) of 0.96 (0.80-1.14) in the pre-biologics period, 0.95 (0.82-1.09) in the early biologics period, and 0.87 (0.75-1.01) in the recent biologics period. A significantly increased risk for malignant lymphoma was observed throughout the observation period (standardized incidence ratio 4.61, 95% confidence interval 3.58-5.85). The disease activity was a significant risk factor for overall malignancies and lung cancer. CONCLUSIONS: Despite the expanding use of methotrexate and biologics, there were no increases in malignancy risk in Japanese patients with RA.

Radiographic factors associated with painful callosities after forefoot surgery in patients with rheumatoid arthritis.

OBJECTIVES: Operative procedures for rheumatoid forefoot deformities have gradually changed from arthrodesis or resection arthroplasty to joint-preserving surgery. Although joint-preserving arthroplasty has yielded good outcomes, painful plantar callosities may occur post-operatively. This study aimed to reveal the radiographic factors associated with painful callosities after joint-preserving surgery for forefoot deformities in patients with rheumatoid arthritis (RA). METHODS: We retrospectively evaluated 166 feet in 133 patients with RA who underwent forefoot joint-preserving arthroplasty, including proximal rotational closing-wedge osteotomies of the first metatarsal, between January 2012 and December 2015. Logistic regression analysis was performed with the objective variable set as the presence/absence of painful plantar callosities at the final observation and the explanatory variables set as several radiographic factors, including post-operative relative first metatarsal length (RML), amount of dorsal dislocation of the fifth metatarsal (5DD), and arc failure of the lesser toes. RESULTS: At the final follow-up, 42 of the 166 feet (25.3%) had painful callosities under the metatarsal heads post-operatively. Logistic regression analysis showed that the RML, 5DD, and lesser toes' arc failure were significantly associated with painful callosities. CONCLUSIONS: We identified that RML, 5DD, and arc failure of the lesser toes were associated with painful plantar callosities after the surgery.

Surgical intervention for patients with rheumatoid arthritis is declining except for foot and ankle surgery: A single-centre, 20-year observational cohort study.

OBJECTIVES: A global downward trend in the number of rheumatoid arthritis (RA)-related surgeries has been reported. The purpose of our study was to investigate the latest trends in RA-related surgeries in a single-centre Japanese RA cohort. METHODS: This study was a retrospective analysis of RA-related surgeries between 2001 and 2020 in the Institute of Rheumatology Rheumatoid Arthritis cohort. An average of 4944 patients per semi-annual survey was included in the study. The primary goal was to analyse the half-year period prevalence proportion (HPP) of RA-related surgeries in a 20-year period, and the secondary goal was to analyse the HPP of surgeries by site or by categories of disease activity. RESULTS: There has been a downward trend in the HPP of RA-related surgeries in the 20-year study period. The total HPP of RA-related surgeries decreased by 50.3% during the 20-year study period. There was a significant decrease in knee, hip, shoulder/elbow, and hand procedures. Only foot/ankle joint surgeries significantly increased in volume during this period (p = .001). The HPP of RA-related surgeries remained unchanged in patients with remission or low disease activity. CONCLUSIONS: The number of RA-related surgeries decreased over a 20-year period, but foot/ankle joint surgeries increased in the site-specific evaluation.

Stress fractures in the forefoot after arthrodesis of the hindfoot in a patient with rheumatoid arthritis: A case report.

Rheumatoid arthritis (RA) is an autoimmune disease that attacks multiple joints throughout the body. Ankle arthrodesis (AA) has been the gold standard surgery for end-stage ankle arthritis in patients with RA. Here, we report the case of a 67-year-old woman with RA who had displacement and loosening of total ankle arthroplasty. The ankle was converted to AA using a metal spacer and an intramedullary nail. The patient had no complications in perioperative terms of arthrodesis. However, multiple fractures were found in the metatarsal bones at the routine 3-year follow-up. Although the patient did not remember any symptoms, the clinical outcome deteriorated compared to that a year before. The hindfoot in this case report was fixed completely by an intramedullary nail, while the midfoot had already involved ankylosis because of severe joint destruction present before the surgery. As a result, the range of motion in the joints of the midfoot and hindfoot was lost, and it is probable that an excessive load was applied to the forefoot during push-off by the toes, resulting in a stress fracture. Patients with RA remain at risk of future progressive joint destruction in every joint of their body. Therefore, surgeons should choose a surgery that preserves ankle motion to decrease the rate of adjacent joint degeneration for severe ankle arthropathy in patients with RA.

Cost-consequence of abatacept as first-line therapy in Japanese rheumatoid arthritis patients using IORRA real-world data.

OBJECTIVES: To investigate the cost-effectiveness of abatacept (ABA) as first-line (1L) therapy in Japanese rheumatoid arthritis (RA) patients using data from the Institute of Rheumatology, Rheumatoid Arthritis database. METHODS: A decision-analytic model was used to estimate the cost per American College of Rheumatology response of at least 50% improvement (ACR50) responder and per patient in Clinical Disease Activity Index (CDAI) and Simplified Disease Activity Index (SDAI) remission from a Japanese healthcare payers' perspective over a 2-year time horizon. Clinical characteristics of patients on ABA-1L were matched with those of patients on ABA second or later line (2L+) or tumour necrosis factor inhibitor (TNFi)-1L directly or using propensity scores. Resource utilisation and medical costs were calculated from the Japan Medical Data Center claims database. Parameter uncertainty was addressed by sensitivity and subgroup analyses (age, treatment duration, Japanese version of Health Assessment Questionnaire [J-HAQ] score). RESULTS: Incremental costs per member per month (ΔPMPM) for ABA-1L versus TNFi-1L and ABA-2L+ were -1,571 Japanese Yen (JPY) and 81 JPY, respectively. For ABA-1L versus TNFi-1L, ΔPMPM by ACR50 response was -11,715 JPY and by CDAI and SDAI remission 11,602 JPY and 47,003 JPY, respectively. Corresponding costs for ABA-1L were lower for all outcome parameters versus those for ABA-2L+. Scenario analyses showed that ABA-1L was cost-effective over TNFi-1L in patients <65 years for any outcome. Furthermore, ABA-1L was cost-effective over ABA-2L+ for all outcomes in patients with age <65 years, disease duration <5 years and J-HAQ ≥1.5. CONCLUSIONS: ABA-1L demonstrated a favourable cost-effectiveness profile in RA patients, accruing savings for the Japanese healthcare payers.

Modern cementless posterior stabilized mobile-bearing total knee arthroplasty shows comparable clinical and radiographical results to its cemented predecessor at 1-year follow-up.

PURPOSE: The purpose of this study was to evaluate perioperative and short-term clinical and radiographical results of a modern PS mobile-bearing cementless TKA system. METHODS: A retrospective review of a consecutive series of TKAs was performed by a single surgeon using a cementless or cemented TKA of the same design (Attune, DePuy Synthes, Massachusetts, USA). The 2011 Knee Society Score, Forgotten Joint Score-12, Hip-Knee-Ankle angle, and the presence of radiolucent lines (RLLs) were reviewed 1-year postoperatively with 1:1 matching performed for age, gender, body mass index, and preoperative UCLA score. Fisher's exact test or independent Student's t-test were used for statistical analyses. RESULTS: Forty-five cementless and 45 cemented TKAs were reviewed after 1:1 matching. The mean operative time was 8.8 min shorter (P < .01), and the mean amount of drainage was 40.0 ml greater (P = .04) in the cementless cohort. At 1-year postoperatively, there were no significant differences in both cohorts in 2011 Knee Scores and Forgotten Joint Scores-12, with no patients requiring revision surgery (NS). The incidence of RLLs was significantly higher in cementless TKAs (51%) than that in cemented TKAs (22%, P < .01). However, the mean width of RLLs in the cementless TKAs (0.2 mm) was significantly smaller (P < .01) than that in the cemented TKAs (0.8 mm) at 1-year postoperatively with no progression. CONCLUSION: A recently introduced cementless PS mobile-bearing TKA design demonstrated comparable postoperative and radiographical results to its cemented predecessor at 1-year follow-up. LEVEL OF EVIDENCE: Retrospective cohort study, Level III.

Foot and ankle functions and deformities focus on posterior tibial tendon dysfunction using magnetic resonance imaging in patients with rheumatoid arthritis.

OBJECTIVES: Posterior tibial tendon dysfunction (PTTD) affects the support of the medial longitudinal arch and stability of the hindfoot. The purpose of this study was to assess the relationships of PTTD with foot and ankle functions and foot deformities in patients with rheumatoid arthritis (RA). METHODS: A total of 129 patients (258 feet) who underwent magnetic plain and contrast-enhanced magnetic resonance imaging were enrolled in this study. Positive magnetic resonance imaging findings were defined as tenosynovitis and incomplete and complete rupture of the posterior tibial tendon. Foot and ankle functions were assessed using the Japanese Society for Surgery of the Foot standard rating system for the RA foot and ankle scale (JSSF-RA) and self-administered foot evaluation questionnaire. Plain radiographs were examined for the hallux valgus angle, first metatarsal and second metatarsal angle, lateral talo-first metatarsal angle, and calcaneal pitch angle. RESULTS: PTTD was associated with motion in the JSSF-RA (p = .024), activities of daily living in JSSF-RA (p = .017), and pain and pain-related factors in the self-administered foot evaluation questionnaire (p = .001). The calcaneal pitch angle was significantly lower in the feet with PTTD than in those without PTTD (median: 16.2° vs. 18.0°; p = .007). CONCLUSIONS: The present study shows that PTTD was associated with foot and ankle functions and flatfoot deformity. Thus, a better understanding of PTTD in patients with RA is important for the management of foot and ankle disorders in clinical practice.

Efficacy of Intra-Articular Injection of 10 mg and 20 mg Triamcinolone for Rheumatoid Arthritis of the Wrist: A Prospective, Randomized, Pilot Study.

Background: To compare the efficacy of intra-articular injection (IA) with 10 mg and 20 mg triamcinolone for treatment of rheumatoid arthritis (RA) of the wrist joint. Methods: We enrolled 20 patients with swelling and pain in wrist due to RA in the present prospective, randomized, pilot study. Patients were randomly assigned in a 1:1 ratio to either the 20 mg or 10 mg group, and received IA of the appropriate dose of triamcinolone. Efficacy was assessed by recording Numerical Rating Scale (NRS) for pain and improvement in power doppler (PD) scale score at weeks 1, 4, and 12 of treatment compared with baseline. The shortened Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH) was recorded at baseline and week 12. Results: The NRS was found to be significantly improved at weeks 4 (p = 0.006) and 12 (p = 0.036) among the total study population. Neither the change in NRS nor the improvement PD scale score from baseline were significantly different between the two groups at any week (NRS: week 1, p = 0.617; week 4, p = 0.727; and week 12, p = 0.878; PD scale score: week 1, p = 0.370; week 4, p = 1.000; and week 12, p = 0.179). Among the entire study population, the QuickDASH was not significantly improved at week 12 nor was the change from baseline significantly different between the two groups at week 12 (p = 0.592). Conclusions: IA of triamcinolone was effective for pain relief in context of RA in the wrist joint. However, in terms of NRS, improvement of PD scale score, and QuickDASH score, the efficacies of 10 mg and 20 mg triamcinolone were not significantly different. Thus, IA of 10 mg triamcinolone may be sufficient for the treatment of RA in the wrist joint.

Joint-Preserving Surgery for Forefoot Deformities in Patients with Rheumatoid Arthritis: A Literature Review.

The combination of first metatarsophalangeal joint arthrodesis and resection arthroplasty of all lesser metatarsal heads has been historically considered the golden standard treatment for rheumatoid forefoot deformities. However, as recent improved management of rheumatoid arthritis have reduced progression of joint destruction, the surgical treatments for rheumatoid forefoot deformities have gradually changed from joint-sacrificing surgery, such as arthrodesis and resection arthroplasty, to joint-preserving surgery. The aim of this literature review was to provide current evidence for joint-preserving surgery for rheumatoid forefoot deformities. We focused on the indications, specific outcomes, and postsurgical complications of joint-preserving surgery in this review.

Difference in patient-reported outcomes of various patellar component designs in total knee arthroplasty: A randomized clinical study.

PURPOSE: This study investigated the clinical effects of different patellar components without being affected by the femoral component design in total knee arthritis (TKA) for patients with knee osteoarthritis (OA). METHODS: In total, 48 patients with OA who met the criteria of the American College of Rheumatology for OA were enrolled and randomly assigned in a 1:1 ratio to two groups according to the usage of patellar component design for TKA (medialized dome type [dome group] or medialized anatomic type [anatomic group]). To evaluate the clinical outcomes for TKA, knee range of motion (ROM), pain intensity of 0-100 mm visual analog scale (pain VAS), and the Japanese Knee Osteoarthritis Measure (JKOM) score were obtained at baseline and year 1. RESULTS: The difference in knee ROM, pain VAS, or total JKOM score at year 1 was not significant between the dome and anatomic groups (p = 0.398, 0.733 and 0.536, respectively). Moreover, similar results were obtained for changes in knee ROM, pain VAS, or total JKOM scores from baseline. In both groups, the pain VAS and total JKOM scores were significantly improved at year 1. CONCLUSION: Both dome and anatomic groups in TKA are significantly effective for pain and function using the JKOM score. However, their efficacy did not differ, according to the JKOM score. Results of this study are rare information focusing on the patellar component design and provide one of the insights into the TKA clinical management.

Patient-Reported and Radiographic Outcomes of Joint-Preserving Surgery for Rheumatoid Forefoot Deformities: A Retrospective Case Series with Mean Follow-up of 6 Years.

BACKGROUND: Rheumatoid arthritis (RA) is an autoimmune disorder and a chronic inflammatory disease that can damage joints throughout the body. As dramatic improvements in medical treatment have contributed to reduced progression of joint destruction, surgical methods for the treatment of RA-related forefoot deformities have gradually changed from joint-sacrificing to joint-preserving. The aim of this study was to assess the long-term outcomes, including patient-reported outcomes, of joint-preserving surgery for forefoot deformities associated with RA. METHODS: This retrospective study included 105 feet in 89 patients with RA who were treated during the period of January 2012 to May 2015 and had a minimum of 5 years of follow-up (mean, 6.0 ± 0.9 years). The patient-reported outcome measure used was the Self-Administered Foot Evaluation Questionnaire (SAFE-Q), which was completed preoperatively and at the latest follow-up (n = 53 feet). The hallux valgus angle (HVA), the intermetatarsal angle (IMA), and the position of the medial sesamoid were measured preoperatively, at 3 months postoperatively, and at the latest follow-up. Cases of delayed wound-healing, hallux valgus recurrence, nonunion at the osteotomy sites, and reoperation were recorded. Kaplan-Meier survival curves were used to determine the estimated survivorship, with reoperation as the end point. RESULTS: Scores of all 5 subscales of the SAFE-Q demonstrated significant improvement at the latest follow-up. The average HVA and IMA decreased significantly 3 months postoperatively, and these measurements remained significantly lower than the preoperative values (p < 0.01). The position of the medial sesamoid at the latest follow-up improved significantly (p < 0.01). Delayed wound-healing was found at the site of surgery in 21 (20.0%) of the 105 feet. Recurrence of hallux valgus was observed in 11 (10.5%) of the feet. There was no case of nonunion at any osteotomy site. Eleven (10.5%) of the feet required reoperation. The estimated survivorship of the studied joint-preserving surgery at 7 years, with reoperation as the end point, was 89.5%. CONCLUSIONS: Satisfactory long-term patient-reported and radiographic outcomes after joint-preserving surgery for forefoot deformities associated with RA can be achieved. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.
