The plantar plate is an important static stabilizer of lesser metatarsophalangeal joints, and disruptions of the plantar plate can lead to significant instability and lesser toe deformities.Our study proposes an inexpensive and versatile method for plantar plate repair
A torn plantar plate is small and difficult to access using regular instruments in a restricted operative field. A unique method for plantar plate repairs was used to repair various configurations of plantar plate tears with standard operative instruments that is available in most operating rooms. A retrospective study was performed on patients who underwent operations for lesser MTPJ instability between September 2015 and December 2019. The outcome analysis included the Lesser Metatarsophalangeal-Interphalangeal Scale from the American Orthopedic Foot and Ankle Society (AOFAS) forefoot score, the Visual Analogue Scale score for pain and satisfaction, and answering the question "Would you recommend this procedure to other patients?"

| Lesser Metatarsophalangeal-Interphalangeal Scale from the Americans Orthopedic Foot and Ankle Society (AOFAS) forefoot score (0-100 points) | One of the most widely used PRO measures for foot and ankle conditions is the American Orthopedic Foot and Ankle Society Score (AOFAS). Developed in 1994, the clinician-based AOFAS covers four different regions of the foot: The ankle-hindfoot, midfoot, metatarsophalangeal (MTP)-interphalangeal (IP) for the hallux, and MTP-IP for the lesser toes. These four anatomic regions have their own version of the AOFAS survey. Each c is designed to be used independent of the others. However, each measure is comprised of nine questions and cover three categories: Pain (40 points), function (50 points) and alignment (10 points). These are all scored together for a total of 100 points. | post-operative >12 months |
| Visual Analogue Scale score (VAS) for pain (0-10 points) | The visual analogue scale or visual analog scale (VAS) is a psychometric response scale which can be used in questionnaires. It is a measurement instrument for subjective characteristics or attitudes that cannot be directly measured. When responding to a VAS item, respondents specify their level of agreement to a statement by indicating a position along a continuous line between two end-points. In this study, pre-operative VAS score and post-operative score for pain were obtained for evaluating the clinical outcome. "0" means no pain; "10" means very painful. | pre-opreative and post-operative >12 months |
| Visual Analogue Scale score for satisfaction (0-10 points) | The visual analogue scale or visual analog scale (VAS) is a psychometric response scale which can be used in questionnaires. It is a measurement instrument for subjective characteristics or attitudes that cannot be directly measured. When responding to a VAS item, respondents specify their level of agreement to a statement by indicating a position along a continuous line between two end-points. In this study, pre-operative VAS score and post-operative score for satisfaction were obtained for evaluating the clinical outcome. "0" means unsatisfied ; "10" means very satisfied. | post-operative >12 months |
| Measure | Description | Time Frame |
|---|---|---|
| hallux valgus angle (degree) | Hallux valgus angle is the angle between the axis of the 1st metatarsal and the axis of the proximal phalanx of the 1st toe. It can only be measured on a radiograph performed whilst weight bearing. In this study, pre-operative and post-operative hallux valgus angle were obtained for evaluating the operative outcome. | pre-opreative and post-operative >12 months |

| 1-2 intermetatarsal angle (degree) | 1-2 intermetatarsal angle is the angle between the axis of the 1st metatarsal and the axis of the 2nd metatarsal. It can only be measured on a radiograph performed whilst weight bearing. In this study, pre-operative and post-operative hallux valgus angle were obtained for evaluating the operative outcome. | pre-opreative and post-operative >12 months |
| Metatarsophalangeal joint angle( for lesser toes, degree) | Metatarsophalangeal joint angle is the angle between the axis of the metatarsal and the axis of the proximal phalanx of the lesser toe. It can only be measured on a radiograph performed whilst weight bearing. positive angle indicates a lateral inclination, and negative angle denotes a varus inclination. In this study, pre-operative and post-operative hallux valgus angle were obtained for evaluating the operative outcome. | pre-opreative and post-operative >12 months |
