Total joint replacement of the first metatarsophalangeal joint with Roto-Glide as alternative to arthrodesis

First Metatarsophalangeal Joint Replacement in a Patient With Monostotic Fibrous Dysplasia and Associated Metatarsophalangeal Arthritis

Fibrous dysplasia (FD) is a benign disorder characterized by the replacement of normal bone tissue with fibrous connective tissue, making the bone more susceptible to fractures and increasing the risk of developing degenerative arthritis in multiple joints. We present an unusual case of monostotic FD affecting the first metatarsal, accompanied by metatarsophalangeal (MTP) arthritis, which caused difficulties in walking, pain, and reduced quality of life. The patient underwent the first MTP joint replacement using the mobile bearing ROTOglide™ first MTP joint replacement system; the use of this specific implant for this indication appears to be a novel aspect in the existing literature. Following the operation, the patient returned to normal activities, experiencing improvements in pain, walking, and quality of life, thus demonstrating excellent outcomes.

Comparison of Total Joint Replacement With Arthrodesis of the First Metatarsophalangeal Joint

BACKGROUND

The aim of this study was to compare outcome (clinical, patient-reported outcome measures, radiologic, joint motion and pedographic) of total joint replacement with Roto-Glide (RG) and arthrodesis (A) for severe osteoarthritis of the first metatarsophalangeal joint (MTP1).

METHODS

All consecutive patients with arthrodesis and RG from January 23, 2011, until September 18, 2019, at the authors' institution were considered for inclusion in the study. Preoperatively and at follow-up (FU), radiographs, and/or weightbearing computed tomographic imaging were obtained. Standard dynamic pedography was performed. Visual analog scale foot and ankle (VASFA), European Foot and Ankle Society (EFAS) score, MTP1 range of motion for dorsiflexion/plantarflexion (DF/PF) were registered and compared preoperatively and at FU.

RESULTS

Seventy RG and 72 arthrodesis patients were included. Preoperative VASFA and EFAS scores did not differ between the RG and arthrodesis groups (average scores: VASFA, 50.6 and 45.6; EFAS score, 10.7 and 10.6, respectively; each P > .05). Wound healing delays without further operative measures were registered in 4 patients (6%) for RG and 5 (7%) for arthrodesis (P = .67), and 5 revisions in 5 patients (7%) for RG and 12 in 8 (11%) for arthrodesis (P = .05). The longest available FU was higher in RG than in arthrodesis (47 vs 37 months on average, P < .001). Pedography showed higher first metatarsal head or sesamoids and lower great toe force percentage from force of entire foot in RG than in arthrodesis (P = .05) resulting in physiological pattern in RG only. VASFA and EFAS scores at FU was higher in RG than in arthrodesis (average scores: VASFA, 72.6 and 63.6; EFAS score, 16.1 and 14.1, respectively; each P < .05). DF/PF measurement was only possible in RG (average value: DF/PF, 36.1/14.0).

CONCLUSION

We found marginally lower revision rates and higher patient-reported outcome measures, joint motion (DF/PF), and more physiologic force distribution at slightly longer FU for the RG group than the arthrodesis group. Longer follow-up and broader clinical reporting are needed to identify the potential deficits of RG.

A bibliometric analysis of published research employing musculoskeletal imaging modalities to evaluate foot osteoarthritis

Objectives

Temporal and global changes in research utilising imaging to assess foot osteoarthritis is currently unknown. This study aimed to undertake a bibliometric analysis of published research to: (1) identify the imaging modalities that have been used to evaluate foot osteoarthritis; (2) explore the temporal changes and global differences in the use of these imaging modalities; and (3) to evaluate performance related to publication- and citation-based metrics.

Methods

A literature search was conducted using Scopus to identify studies which had used imaging to assess foot osteoarthritis. Extracted data included publication year, imaging modality, citations, affiliations, and author collaboration networks. Temporal trends in the use of each imaging modality were analysed. Performance analysis and science mapping were used to analyse citations and collaboration networks.

Results

158 studies were identified between 1980 and 2021. Plain radiography was the most widely used modality, followed by computed tomography, magnetic resonance imaging (MRI) and ultrasound imaging (USI), respectively. The number of published studies increased over time for each imaging modality (all P ≥ 0.018). The most productive country was the United States of America (USA), followed by the United Kingdom and Australia. International authorship collaboration was evident in 57 (36.1%) studies. The average citation rate was 23.4 per study, with an average annual citation rate of 2.1.

Conclusions

Published research employing imaging to assess foot osteoarthritis has increased substantially over the past four decades. Although plain radiography remains the gold standard modality, the emergence of MRI and USI in the past two decades continues to advance knowledge and progress research in this field.

Long-term results of total joint arthroplasty and phalangeal hemiarthroplasty of the first metatarsophalangeal joint using the ToeFit Plus™ system

BACKGROUND

This paper compares long term success rate of MTP joint replacement for hallux rigidus. We provide long term results of MTP joint replacement with the use of the ToeFit Plus™ System.

MATERIALS AND METHODS

Our group consisted of 19 total joint replacements and 12 hemiarthroplasties in 18 and 11 patients respectively, performed between 2005-2009. The average follow-up period was 12.2 years (range 9.8-13.7, SD 1.1) for total arthroplasty group and 11.1 years (range 9.5-13.9, SD 1.7) for hemiarthroplasty group. In all followed patients AOFAS score was calculated along with the range of motion assessment.

RESULTS

Average AOFAS score improved from 37 preoperatively to 79 at the time of last follow-up in total arthroplasty group and from 45 to 86 in the hemiarthroplasty group, with consideration to the statistically considerable difference of both groups. The total range of motion improved on average from 14° to the current 32° in patients with total arthroplasty and from 15° to 32° with hemiarthroplasty. The total number of cases that required surgical revision was 7 (37%) in total arthroplasty group and 2 (17%) in hemiarthroplasty group.

CONCLUSION

Due to the high percentage of failure that was shown in our long term results, we no longer utilise the ToeFit Plus™ System.
