Summary
The ROTO-glide device shows promising early results for first metatarsophalangeal joint (MTPJ) replacement, improving patient function and range of motion. Further evaluation is recommended for this MTPJ implant.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
Background:
- First metatarsophalangeal joint (MTPJ) arthritis management often involves arthrodesis, but joint replacement is an alternative.
- The ROTO-glide prosthesis is evaluated for MTPJ replacement in this study.
Purpose of the Study:
- To conduct a multi-center service evaluation of the ROTO-glide device for first MTPJ replacement.
- To assess the safety and efficacy of the ROTO-glide prosthesis in patients with end-stage MTPJ arthritis.
Main Methods:
- 33 ROTO-glide procedures were performed on 30 patients across 7 UK sites.
- Patients were assessed pre- and post-operatively using AOFAS and Oxford forefoot (MOXFQ) scores, along with plain radiographs.
- Exclusion criteria included hallux valgus, inflammatory joint disease, and ages outside 45-80 years.
Main Results:
- Average patient age was 58.6 years, with a follow-up of 16.9 months.
- Significant improvements were observed in AOFAS scores (41.4 to 76) and MOXFQ index (43 to 17).
- Average range of motion increased from 32° to 61°, with 2 minor complications and no revisions.
Conclusions:
- Early results from this multi-center evaluation support the continued use of the ROTO-glide prosthesis for MTPJ replacement.
- Further evaluation of the ROTO-glide device is warranted based on these positive outcomes.
