Wichmann J, Gesk TS, Leyer M. Acceptance of AI in Health Care for Short- and Long-Term Treatments: Pilot Development Study of an Integrated Theoretical Model. JMIR Form Res 2024; 8:e48600. [PMID: 39024565 PMCID: PMC11294784 DOI: 10.2196/48600] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2023] [Revised: 02/14/2024] [Accepted: 04/29/2024] [Indexed: 07/20/2024] Open
Abstract
BACKGROUND As digital technologies and especially artificial intelligence (AI) become increasingly important in health care, it is essential to determine whether and why potential users intend to use related health information systems (HIS). Several theories exist, but they focus mainly on aspects of health care or information systems, in addition to general psychological theories, and hence provide a small number of variables to explain future behavior. Thus, research that provides a larger number of variables by combining several theories from health care, information systems, and psychology is necessary. OBJECTIVE This study aims to investigate the intention to use new HIS for decisions concerning short- and long-term medical treatments using an integrated approach with several variables to explain future behavior. METHODS We developed an integrated theoretical model based on theories from health care, information systems, and psychology that allowed us to analyze the duality approach of adaptive and nonadaptive appraisals and their influence on the intention to use HIS. We applied the integrated theoretical model to the short-term treatment using AI-based HIS for surgery and the long-term treatment of diabetes tracking using survey data with structured equation modeling. To differentiate between certain levels of AI involvement, we used several scenarios that include treatments by physicians only, physicians with AI support, and AI only to understand how individuals perceive the influence of AI. RESULTS Our results showed that for short- and long-term treatments, the variables perceived threats, fear (disease), perceived efficacy, attitude (HIS), and perceived norms are important to consider when determining the intention to use AI-based HIS. Furthermore, the results revealed that perceived efficacy and attitude (HIS) are the most important variables to determine intention to use for all treatments and scenarios. In contrast, abilities (HIS) were important for short-term treatments only. For our 9 scenarios, adaptive and nonadaptive appraisals were both important to determine intention to use, depending on whether the treatment is known. Furthermore, we determined R² values that varied between 57.9% and 81.7% for our scenarios, which showed that the explanation power of our model is medium to good. CONCLUSIONS We contribute to HIS literature by highlighting the importance of integrating disease- and technology-related factors and by providing an integrated theoretical model. As such, we show how adaptive and nonadaptive appraisals should be arranged to report on medical decisions in the future, especially in the short and long terms. Physicians and HIS developers can use our insights to identify promising rationale for HIS adoption concerning short- and long-term treatments and adapt and develop HIS accordingly. Specifically, HIS developers should ensure that future HIS act in terms of HIS functions, as our study shows that efficient HIS lead to a positive attitude toward the HIS and ultimately to a higher intention to use.

EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2024; 34:2483-2492. [PMID: 38644419 DOI: 10.1007/s00590-024-03950-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/10/2024] [Accepted: 04/03/2024] [Indexed: 04/23/2024]
Abstract
PURPOSE The purpose of our work was to demonstrate the surgical technique of ankle arthrodesis using the minimally-invasive transfibular (MITF) approach, which minimizes soft tissue damage and is advantageous for high-risk patients. METHODS In this prospective study, a total of 12 patients with end-stage varus ankle osteoarthritis, including high-risk individuals, underwent ankle arthrodesis using the MITF approach. The technique involves a unique osteotomy at the joint space level, minimizing soft tissue detachment from the fibula. The primary outcomes assessed included bony union, time to weight-bearing, correction of varus deformity, and functional outcomes measured by the American Orthopedic Foot and Ankle Society (AOFAS) hindfoot scale. However, the study's limitations encompass a small sample size and the absence of a control group. RESULTS At 6 months post-operation, all patients achieved bony union, with a mean time to union of 13.7 ± 5.2 weeks. The average time to initiate weight-bearing without additional support was 11.2 ± 3.8 weeks. Preoperative varus deformity (17.08 ± 8.36 degrees) and talar tilt (8.75 ± 4.33 degrees) were successfully corrected, with postoperative alignment within 0-5 degrees of valgus. Functional outcomes showed a significant improvement in AOFAS scores from 37.83 ± 7.79 points preoperatively to 77.42 ± 5.63 points one year after surgery (p = 0.002). Minor complications occurred in two patients, both effectively treated with local therapy and antibiotics. CONCLUSIONS The MITF approach for ankle arthrodesis demonstrates promising results in addressing end-stage varus ankle osteoarthritis, even in high-risk patients. However, the study's limitations highlight the need for a prospective comparative clinical trial with a larger sample size to ascertain the technique's effectiveness and safety definitively.

Abstract
Recent advancements in orthopedic surgery have greatly improved the management of musculoskeletal disorders and injuries. This review discusses the latest therapeutic approaches that have emerged in orthopedics. We examine the use of regenerative medicine, including stem cell therapy and platelet-rich plasma (PRP) injections, to accelerate healing and promote tissue regeneration. Additionally, we explore the application of robotic-assisted surgery, which provides greater precision and accuracy during surgical procedures. We also delve into the emergence of personalized medicine, which tailors treatments to individual patients based on their unique genetic and environmental factors. Furthermore, we discuss telemedicine and remote patient monitoring as methods for improving patient outcomes and reducing healthcare costs. Finally, we examine the growing interest in using artificial intelligence and machine learning in orthopedics, particularly in diagnosis and treatment planning. Overall, these advancements in therapeutic approaches have significantly improved patient outcomes, reduced recovery times, and enhanced the overall quality of care in orthopedic surgery.

Clin Orthop Surg 2024; 16:141-148. [PMID: 38304214 PMCID: PMC10825248 DOI: 10.4055/cios23221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Revised: 10/31/2023] [Accepted: 10/31/2023] [Indexed: 02/03/2024] Open
Abstract
Background To evaluate the degree of deformation in patients with ankle osteoarthritis (OA), it is essential to measure the three-dimensional (3D), in other words, stereoscopic alignment of the ankle, subtalar, and foot arches. Generally, measurement of radiological parameters use two-dimensional (2D) anteroposterior and lateral radiographs in a weight-bearing state; however, computer-aided 3D analysis (Disior) using weight-bearing cone-beam computed tomography (CBCT) has recently been introduced. Methods In this study, we compared the 2D human radiographic method with a stereoscopic image in patients with ankle arthritis. We enrolled 57 patients diagnosed with OA (28 left and 29 right) and obtained both standing radiographs and weight-bearing CBCT. Patients were divided by the Takakura stage. The interclass correlation coefficient (ICC) for each result was confirmed. Results On the ICC between 2D radiographs and 3D analysis, the tibiotalar surface angle and lateral talo-1st metatarsal angle showed a good ICC grade (> 0.6), while other parameters did not have significant ICC results. Three-dimension was superior to radiographs in terms of statistical significance. Conclusions We demonstrated that 2D and stereoscopic images are useful for the diagnosis of OA. Our study also confirmed that the radiographic features affected by ankle OA varied. However, according to the results, the typical radiography is not sufficient to diagnose and determine a treatment plan for ankle OA. Therefore, the method of using 3D images should be considered.

Sci Rep 2023; 13:18614. [PMID: 37903965 PMCID: PMC10616077 DOI: 10.1038/s41598-023-46034-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Accepted: 10/26/2023] [Indexed: 11/01/2023] Open
Abstract
Ankle arthrodesis is commonly performed to treat end-stage ankle osteoarthritis. The aim of this study was to determine whether the use of fibular autograft might increase the fusion rate and decrease the complication rate in ankle arthrodesis (AA) fixed using cannulated screws. To perform this PRISMA-compliant proportional meta-analysis, multiple databases were searched for studies in which patients undergone AA (using exclusively cannulated screws and augmented with fibular bone graft) were followed. The characteristics of the cohort, the study design, surgical details, the nonunion and complication rate at the longest follow-up were extracted and recorded. The modified Coleman Methodology Score (mCMS) was applied to appraise the quality of studies. Two groups were built: arthrodeses fixed with screws combined with cancellous autograft (G1) and arthrodeses fixed with screws combined with cancellous autograft and augmented with a lateral fibular onlay (G2). A third group (arthrodeses fixed with screws and no graft, G3) was extracted from previous literature for a further comparison. Overall, we included 306 ankles (296 patients) from ten series (ten studies). In G1 and G2 there were 118 ankles (111 patients) and 188 ankles (185 patients), respectively. In patients where cancellous autograft was used, a further augmentation with a fibular lateral strut autograft did not change significantly the nonunion (4% [95% CI 1-9] in G1 vs. 2% [95% CI 0-5) in G2, p = 0.99) nor the complication rate (18% [95% CI 0-36] in G1 vs. 13% [95% CI 6-21) in G2, p = 0.71). Upon comparison with 667 ankles (659 patients, G3) in which arthrodeses had been performed without grafting, the nonunion and complication rates did not differ significantly either (pooled estimates: 3% [95% CI 1-3) in G1 + G2 vs. 3% [95% CI 2-4] in G3, p = 0.73 for nonunion; 15% [8-23] in G1 + G2 vs. 13% [95% CI 9-17] in G3, p = 0.93 for complications). In ankle arthrodesis fixed with cannulated screws combined with cancellous autograft at the fusion site, a construct augmentation with a distal fibular onlay strut graft positioned laterally at the ankle joint does not reduce the risk of nonunion or complication. In general, the use of bone graft does not influence significantly the nonunion nor the complication rate as compared to non-grafted screw-fixed ankle arthrodeses.Kindly check and confirm the corresponding author mail id is correctly identified.It's all correct.

Abstract
This study aimed to compare the efficacy of arthrodesis with various fixation methods in the treatment of advanced ankle osteoarthritis. Thirty-two patients with osteoarthritis of the ankle (mean age 59.91±6.16 years) took part in the study. The patients were divided into 2 groups - Ilizarov apparatus (21 patients) and screw fixation (11 patients). Each group was also divided into subgroups based on etiology - posttraumatic and nontraumatic. The AOFAS and VAS scales were compared in the preoperative and postoperative periods. It was found that screw fixation was more effective in the treatment of late stages of osteoarthritis (OA) of the ankle during the postoperative period. Comparison of the AOFAS and VAS scales showed no significant differences between the groups in the preoperative period (p = 0.838; p = 0.937). After 6 months, the results were better in the screw fixation group (p = 0.042; p = 0.047). Complications were observed for a third of the patients (10 patients). 6 patients had pain in the operated limb (4 patients in the Ilizarov apparatus group). Three patients in the Ilizarov apparatus group developed a superficial infection, and one developed a deep infection. Different etiology did not affect the postoperative efficacy of arthrodesis. The choice of the type of should be related to a clear protocol for the presence of complications. When choosing the type of fixation for arthrodesis, a patient's condition as well as a surgeon's preferences should be taken into account.

Irritation from metalwork after ankle arthrodesis fixed using screws: a proportional meta-analysis and systematic review. Arch Orthop Trauma Surg 2023:10.1007/s00402-023-04813-1. [PMID: 36795152 PMCID: PMC10374802 DOI: 10.1007/s00402-023-04813-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Accepted: 02/05/2023] [Indexed: 02/17/2023]
Abstract
OBJECTIVE Ankle arthrodesis (AA) is often fixed using cannulated screws. The irritation from metalwork is a relatively common complication, but there is no consensus regarding the need to remove the screws on a systematic basis. The aim of this study was to determine (1) the proportion of screws removed after AA and (2) whether predictors of screw removal could be identified. METHODS This PRISMA-compliant systematic review was part of a larger previous protocol registered on the PROSPERO platform. Multiple databases were searched including studies in which patients undergone AA using screws as exclusive fixation method were followed. Data were harvested regarding the cohort, the study design, the surgical technique, the nonunion and complication rate at the longest follow-up. Risk of bias was assessed using the modified Coleman Methodology Score (mCMS). RESULTS Forty-four series of patients from thirty-eight studies (1990 ankles, 1934 patients) were selected. The average follow-up was 40.8 months (range 12-110). In all studies, hardware was removed due to symptoms reported by patients and related to the screws. The pooled proportion of removal of metalwork was 3% (95% CI 2-4). The pooled proportion of fusion was 96% (95%CI 95-98), while the pooled proportion of complications and reoperations (excluding the removal of metalwork) stood at 15% (95% CI 11-18) and 3% (95% CI 2-4), respectively. The mean mCMS (50.8 ± 8.1, range 35-66) revealed only an overall fair quality of studies. The univariate analysis and the multivariate model showed that the year of publication (R = - 0.004; p = 0.01) and the number of screws (R = 0.08; p = 0.01) were associated with the screw removal rate. Specifically, we found that over time the removal rate decreased by 0.4% per year and that the use of three screws instead of two reduced the risk of removal of metalwork by 8%. CONCLUSIONS In this review, removal of metalwork after ankle arthrodesis using cannulated screws was needed in 3% of cases at an average follow-up of 40.8 months. It was indicated only in case of symptoms related to soft tissue irritation from screws. The use of three screws was paradoxically related to a reduced risk of removal of screws as compared to two-screw constructs. LEVEL OF EVIDENCE Level IV, systematic review of Level IV.

Abstract
Актуальность. Несмотря на существующее значительное количество разнообразных методик, применяемых для артродеза голеностопного сустава, ряд авторов указывают на определенные технические сложности указанных операций, потерю коррекции заданного положения таранной и большеберцовой костей в процессе анкилозирования, несращения. Проблема совершенствования методики фиксации при артродезе голеностопного сустава требует новых решений. Цель провести сравнительный биомеханический анализ стабильности фиксации при артродезе голеностопного сустава тремя спонгиозными винтами и разработанной пластиной, комбинируемой с двумя спонгиозными винтами, методом конечных элементов. Материалы и методы. Методом конечных элементов выполнена оценка биомеханических характеристик трех вариантов систем фиксации голеностопного сустава при артродезе: три спонгиозных винта, разработанная пластина, комбинируемая с двумя спонгиозными винтами, проксимальный винт в пластине кортикальный, а также разработанная пластина, комбинируемая с двумя спонгиозными винтами, проксимальный винт в пластине с угловой стабильностью. Изучены напряжения и деформации при приложении различных видов нагрузок. Результаты. В модели фиксации голеностопного сустава передней пластиной, комбинируемой с двумя спонгиозными винтами и проксимальным кортикальным винтом, имплантаты и таранная кость испытывали наименьшие напряжения по сравнению с двумя другими моделями. Так, максимальное эквивалентное напряжение в имплантатах при втором варианте составило 68-124 МПа, при первом варианте 92-147 МПа, при третьем 130-331 МПа. Эквивалентное напряжение в таранной кости во втором варианте фиксации составило от 20 до 46 МПа, в первом и третьем вариантах 28-58 МПа и 47-65 МПа, соответственно. Показатели максимального контактного давления на границе большеберцовой и таранной костей оказались наибольшими в первом варианте по сравнению с двумя другими моделями (34 МПа, 31 МПа и 31 МПа соответственно).
Заключение. Среди изученных систем фиксации голеностопного сустава для артродеза, применение передней пластины, комбинируемой с двумя спонгиозными винтами и проксимальным кортикальным винтом, является наиболее предпочтительным с точки зрения биомеханики.

Abstract
Objective To evaluate the clinical curative effect of Ilizarov external fixation and ankle arthrodesis in the treatment of elderly traumatic ankle arthritis. Methods From June 2013 to August 2019, 72 patients with elderly traumatic ankle arthritis were treated with arthrodesis through Ilizarov external fixation technique in our institution. Conventional double‐feet standing X‐ray films were taken before and after operation. The tibiotalar angle on X‐ray image was measured to evaluate the degree of talipes varus and valgus. The Foot and Ankle pain score of American Orthopaedics Foot and Ankle Society (AOFAS) and Visual Analog Scale (VAS) were compared by using paired t‐test to evaluate the functional recovery. Results All of the patients acquired effective postoperative 18–49 months follow‐up, with an average of 31.5 months. All patients were included in the analysis, among which 38 cases were males and 34 cases were females, with an average of 65.4 years (ranging from 60 to 74). All ankles achieved bony fusion; the clinical healing time was 12.7 weeks on average (11–18 weeks). The AOFAS score was 45.36 ± 6.43 preoperatively and 80.25 ± 9.16 at 12 months post‐operation, with a statistically significant difference (p < 0.0001). The VAS score was 8.56 ± 1.85 on average preoperatively and 2.72 ± 0.83 at 12 months post‐operation, with a statistically significant difference (p < 0.0001). The tibiotalar angle was 101.93° ± 4.12° preoperatively and 94.45° ± 2.37° at 12 months post‐operation, with a statistically significant difference (p < 0.0001). The results of the functional evaluation indicated that 44 patients (61.1%) had excellent results, 18 (25%) had good results, and 10 (13.9%) had fair results. Conclusion Our study demonstrated that it is possible to obtain satisfactory outcome with Ilizarov external fixation and ankle arthrodesis in the treatment of elderly traumatic ankle arthritis.

[PMID: 35743458 PMCID: PMC9224582 DOI: 10.3390/jcm11123387] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2022] [Revised: 06/04/2022] [Accepted: 06/09/2022] [Indexed: 02/04/2023] Open
Abstract
Tibiotalar arthrodesis successfully treats ankle arthritis but carries risk of nonunion. It is unclear whether concurrent distal tibiofibular arthrodesis affects tibiotalar nonunion rate. The purpose of this study is to compare tibiotalar nonunion and complication rates in patients with versus without a distal tibiofibular arthrodesis. This is a retrospective review of 516 consecutive ankle arthrodesis performed between March 2002 and May 2016. A total of 319 ankles (312 patients) underwent primary, open tibiotalar arthrodesis (227 with distal tibiofibular arthrodesis, 92 without). Primary outcome measure was nonunion rate. Secondary outcome measures were time to tibiotalar union, rate of development of post-operative deep vein thrombosis (DVT)/pulmonary embolism (PE), rate of deep wound complications, and rate of return to operating room (OR). No differences in nonunion rates were observed in both cohorts of patients with versus without distal tibiofibular arthrodesis: 17/227 (7.5%) versus 11/92 (12%) (p = 0.2), respectively, odds ratio was 0.74, 95% CI: 0.29~2.08 (p = 0.55). There was no difference in deep wound complications (5.3% versus 10.9%, p = 0.42), time to union (3.7 months versus 4.1 months, p = 0.72), or rate of development of DVT/PE (5.2% versus 2.2%, p = 0.18) between patients with and without distal tibiofibular arthrodesis, respectively. This is the first study directly comparing nonunion and complication rates in primary, open ankle arthrodesis with and without distal tibiofibular arthrodesis. Inclusion of the distal fibular joint with the tibiotalar fusion was not associated with a change in tibiotalar nonunion rate, time to union, wound complications, or postoperative DVT/PE.

Orthop Surg 2022; 14:937-945. [PMID: 35441475 PMCID: PMC9087455 DOI: 10.1111/os.13286] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Revised: 03/18/2022] [Accepted: 03/21/2022] [Indexed: 02/05/2023] Open
Abstract
Objective To evaluate the outcomes of Ilizarov ankle arthrodesis in the treatment of end‐stage varus ankle osteoarthritis (OA). Methods This was a retrospective study of 63 patients with varus ankle OA who underwent Ilizarov ankle arthrodesis between June 2013 and December 2018. There were 24 males and 39 females with an average age of 56.57 ± 4.45 years (range, 47–64 years). Thirty‐six cases were affected on the left side, and 27 were affected on the right side. The patients' mean body mass index (BMI) was 25.18 ± 2.93 kg/m2. According to the modified Takakura staging criteria, there were 18 cases of stage 3b (28.57%) and 45 cases of stage 4 (71.43%). Nine patients were primary (14.29%), 48 were traumatic (76.19%), and six were caused by rheumatoid OA (9.52%). Functional assessments were performed according to the American Orthopedic Foot and Ankle Society (AOFAS) ankle‐hindfoot score, Ankle Osteoarthritis Scale (AOS), and visual analogue scale (VAS). The tibial anterior surface angle (TAS), coronal plane tibial‐talar angle (CPT), talar tilt angle (TT), deformity angle (DA), and tibial lateral surface angle (TLS) were assessed on X‐ray films. Results The average operation time was 147.84 ± 13.67 min (range, 135–168 min). The average follow‐up time was 34.24 ± 8.72 months (range, 24–61 months). Bony fusion was achieved in all ankles, and the fusion time was 12.43 ± 1.99 weeks on average. The average AOFAS score at the final follow‐up increased from 42.14 ± 8.66 to 80.90 ± 6.80. The average VAS score and AOS pain and disability scores at the final follow‐up decreased from 7.29 ± 1.27 to 2.24 ± 0.94, from 67.94 ± 7.68 to 27.92 ± 5.82, and from 71.64 ± 9.37 to 41.32 ± 8.99, respectively. The average TAS, CPT, and TLS at the final follow‐up increased from 77.76° ± 4.44° to 89.81° ± 1.25°, from 69.04° ± 3.73° to 90.43° ± 1.80°, and from 82.14° ± 3.77° to 88.67° ± 2.50°, respectively. The average TT and DA at the final follow‐up decreased from 8.76° ± 4.30° to 2.05° ± 1.28° and from 20.95° ± 3.73° to 1.57° ± 0.93°, respectively. Three patients developed superficial pin tract infections, all settled with local dressing and antibiotic treatment. Two patients were found to have subtalar arthritis and underwent conservative treatment. Conclusion Ankle arthrodesis using the Ilizarov technique is efficient in treating end‐stage varus ankle OA.

Effect of Platelet-Rich Plasma Injections vs Placebo on Ankle Symptoms and Function in Patients With Ankle Osteoarthritis: A Randomized Clinical Trial. JAMA 2021; 326:1595-1605. [PMID: 34698782 PMCID: PMC8548954 DOI: 10.1001/jama.2021.16602] [Citation(s) in RCA: 62] [Impact Index Per Article: 20.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/14/2022]
Abstract
IMPORTANCE Approximately 3.4% of adults have ankle (tibiotalar) osteoarthritis and, among younger patients, ankle osteoarthritis is more common than knee and hip osteoarthritis. Few effective nonsurgical interventions exist, but platelet-rich plasma (PRP) injections are widely used, with some evidence of efficacy in knee osteoarthritis. OBJECTIVE To determine the effect of PRP injections on symptoms and function in patients with ankle osteoarthritis. DESIGN, SETTING, AND PARTICIPANTS A multicenter, block-randomized, double-blinded, placebo-controlled clinical trial performed at 6 sites in the Netherlands that included 100 patients with pain greater than 40 on a visual analog scale (range, 0-100) and tibiotalar joint space narrowing. Enrollment began on August 24, 2018, and follow-up was completed on December 3, 2020. INTERVENTIONS Patients were randomly assigned (1:1) to receive 2 ultrasonography-guided intra-articular injections of either PRP (n = 48) or placebo (saline; n = 52). MAIN OUTCOMES AND MEASURES The primary outcome was the validated American Orthopaedic Foot and Ankle Society score (range, 0-100; higher scores indicate less pain and better function; minimal clinically important difference, 12 points) over 26 weeks. RESULTS Among 100 randomized patients (mean age, 56 years; 45 [45%] women), no patients were lost to follow-up for the primary outcome. Compared with baseline values, the mean American Orthopaedic Foot and Ankle Society score improved by 10 points in the PRP group (from 63 to 73 points [95% CI, 6-14]; P < .001) and 11 points in the placebo group (from 64 to 75 points [95% CI, 7-15]; P < .001). The adjusted between-group difference over 26 weeks was -1 ([95% CI, -6 to 3]; P = .56). One serious adverse event was reported in the placebo group, which was unrelated to the intervention; there were 13 other adverse events in the PRP group and 8 in the placebo group. CONCLUSIONS AND RELEVANCE Among patients with ankle osteoarthritis, intra-articular PRP injections, compared with placebo injections, did not significantly improve ankle symptoms and function over 26 weeks. The results of this study do not support the use of PRP injections for ankle osteoarthritis. TRIAL REGISTRATION Netherlands Trial Register: NTR7261.
