Design outcomes

Primary

MeasureTime frame
Patient satisfaction with use of clinical scores and questionnaires. The following methods will be used: § The Ankle-Hindfoot Score developed by the American Orthopaedic Foot and Ankle Society (AOFAS), a 100-point scoring system constituted of both subjective and objective clinical parameters. § The Foot Function Index (FFI), a patient derived questionnaire of 23 items, which refers to residual complaints in foot and ankle during daily life (past week). A Dutch version of this questionnaire has been validated. § A Visual Analog Scale (VAS) will be used to score residual pain, limitation of functioning and satisfaction of treatment result. See the appendices for examples. Chart review to record any complication related to the total ankle arthroplasty.

Secondary

MeasureTime frame
Radiographs are studied before, directly after and at latest follow up. These measurements will be carried out by a radiologist not being involved in the treatment of these patients. Criteria used for follow up were as follow: 1. Pre-operative grading of arthritis of the ankle joint, and pre- and post-operative grading of the subtalar joint. 2. Position of the hindfoot (varus/valgus) pre-operative and position of the prosthesis (varus/valgus) post-operative. 3. Osseous integration of the prosthesis. Radiolucency more then 2mm, cavitation or migration of the components were markers of loosening. 4. Measurement of the tibiotalar ratio. 5. Measurement of the inclination of the tibial component to the long axis of the tibia.
