NCT ID: NCT03935880

Last Updated: 2022-10-28

Results Overview

The Foot and Ankle Ability Measure (FAAM-ADL) is a self-report outcome instrument developed to assess physical function for individuals with foot and ankle related impairments. The 21-item FAAM-ADL Questionnaire: scored as N/A, unable to do, extreme difficulty, moderate difficulty, slight difficulty, no difficulty, and/or a percentage (scale from 0-100, where higher scores indicate better physical function).

Measure
Cartiva Hemiarthroplasty
Cartiva implant: The procedure starts with a small incision over the top of the 1st MTP joint. The joint is exposed. Bone spurs on the metatarsal and proximal phalanx are resected, leaving approximately 2 mm of surrounding bone on the metatarsal head. A guide pin is placed within the metatarsal and a drill is then used to create a site for the implant. The implant is then placed using the implant introducer. The incision is then closed and a sterile dressing is placed.
Cheilectomy
Bone spur removal Cheilectomy: A small incision is made over the top of the 1st MTP joint. The joint is exposed. Bone spurs on the metatarsal and proximal phalanx are resected. The top of the metatarsal head is then cut with a sagittal saw. Additional bone spurs are resected. The incision is closed and a sterile dressing is placed.

The Foot and Ankle Ability Measure (FAAM-Sports) is a self-report outcome instrument developed to assess physical function for individuals with foot and ankle related impairments. FAAM-Sports Questionnaire is an 8-item survey: scored as N/A, unable to do, extreme difficulty, moderate difficulty, slight difficulty, no difficulty, and/or a percentage (scale from 0-100, where higher scores indicate higher level of physical function).

This is a measure of the amount of dorsiflexion of the first metatarsophalangeal joint. It is performed by the clinician and measured with a protractor in clinic. It was measured preoperatively and post operatively.
